Half-year results to 30 June 2022

 

Gresham House Energy Storage Fund plc, the UK's largest fund investing in utility-scale battery energy storage systems (BESS) to power the renewable energy transition, announces its half-year results for the period ending 30 June 2022.

 

Performance highlights in H1 2022

·    Net Asset Value (NAV) up 53.5% to £785.4mn (31 December 2021: £511.7mn)

·    NAV total return of 27.2% with NAV per share rising to 145.11p (31 Dec 2021 :116.86p)

·    Share price total return of 23.3% vs FTSE All Share Index total return of -4.6% in H1 22.  Since IPO, returns have been 86.9% and 15.8% respectively

·    Dividends of 3.5p per share paid in H1 22, with Operational Dividend Cover at 1.18x

·    Underlying Operational Portfolio Revenue rose 20.6% to £30.1mn (H1 21: £24.9mn) and EBITDA stood at £22.7mn (H1 21: £22.4mn)

·    Weighted average discount rate of 10.79% for assets valued on a discounted cash flow basis (31 December 2021: 10.77%)

 

Deployment, Fundraising

·    425MW across 17 operational projects as at 30 June 2022, which has risen to 500MW across 19 operational projects as at 31 August 2022

·    602MW across 11 projects under construction as at 30 June 2022, 527MW as at 30 August 2022, and a further 90MW (Enderby and Coupar Angus) due to commission in the coming days

·    Total operating capacity of over 1GW / 1.2GWh¹ targeted by end Q1 23. All projects 100%-owned

·    Target portfolio of 1.6GW by mid-2024 with a duration of 2.1GWh[1]

·    £150mn raised in oversubscribed equity placing in May 2022

·    Significant additional pipeline in progress in GB as well as Overseas following recent Investment Policy changes

·    Timely commissioning of projects is our key focus by resolving connection bottlenecks in the industry

 

Market environment and outlook

·    UK renewable penetration reached a record 45.5%[2] in Q1 22 driven by offshore wind

·    11GW of renewable capacity contracted in latest Contracts for Difference (CfD) subsidy auctions, which could drive renewable penetration above 65% within 5 years, underpinning the need for BESS

·    Power price volatility primarily driven by renewables as well as shortfalls in generation capacity and gas supply constraints in Europe in the near term

 

Other highlights

·    NAV per share increase in H1 22 assisted by upward revaluations of projects as they go from being valued at cost to a fair value using a net present value basis, reflecting the attractive underlying internal rates of return (IRRs) of our projects at the time they are acquired. Discount rate assumptions have remained unchanged during the period

·    Revenues have remained high, supported by elevated frequency response pricing and a strong trading backdrop. Frequency response pricing is beginning to drop as additional BESS capacity becomes operational

·    The very recent announcement by the Chancellor of the Exchequer of the cancellation of the previously planned Corporation Tax increase to 25% from April 2023, is expected to contribute positively to the Q3 2023 NAV, and NAV per share. In addition, we are still assessing the potential impact over time of FOREX movements

·    Awarded Best Sustainable Specialist Fund at the Investment Week Sustainable Investment Awards for the second year in succession

 

John Leggate CBE, Chair of Gresham House Energy Storage Fund plc, said:

 

"We are pleased with GRID's performance in the first half of the year as we continue to deploy essential battery energy storage infrastructure and deliver above-target total returns to shareholders. We have started to draw down on our debt facilities as expected. Combined with the £150 million equity we raised from shareholders, we expect these funds to deliver most of the existing pipeline, taking GRID to over 1GW of capacity, currently expected by the end of Q1 2023.

 

"We are ambitious to scale up GRID, both in the UK and beyond, enabling a cost-effective transition to net zero, supporting near-term energy security as gas supplies continue to be unreliable while helping maximise the output from low-cost renewable energy sources."

 

Ben Guest, Fund Manager of Gresham House Energy Storage Fund plc and Managing Director of Gresham House New Energy, said:

 

"It has been gratifying to see an increase in our operational capacity, with lots more expected, which is expected to drive growth proportionately in revenues, EBITDA and dividend cover, all things being equal.

 

"Our next batch of projects is in advanced stages of construction; as of today, a further 527MW across 9 projects are anticipated to commission in the next six months, going into 2023. Beyond that, our project pipeline into 2024 is also strong, with over 500MW planned for the 12-18 months that follow. 

 

"GB needs at least 20GW of BESS by 2030, demonstrating its critical importance to the energy transition. We are working on additional pipeline both in GB and Overseas, and we look forward to providing updates as this work progresses.

 

"The rate of deployment of BESS continues to lag the deployment of renewables in GB and this will continue to underpin revenues for the sector for years to come. However, while this backdrop is positive it is important for the industry to acknowledge the need for the rate of deployment of BESS to accelerate. While lockdowns and supply chain issues caused constraints in recent times, the main bottleneck today is in the slow rate of grid connection activity, impacting the industrywide deployment of BESS. We invite Ofgem, grid companies and other stakeholders to act to solve this issue. It is not in anyone's interest to see the unnecessary curtailment of incremental renewable generation and for associated balancing costs to increase exponentially due to a lack of flexible generation."

 

 The Company's Interim Report and Financial Statements for the period ending 30 June 2022 are included in this announcement http://www.rns-pdf.londonstockexchange.com/rns/7035A_1-2022-9-26.pdf, available on the Company's website https://greshamhouse.com/real-assets/new-energy-sustainable-infrastructure/gresham-house-energy-storage-fund-plc/ and also on the National Storage Mechanism https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

Definition of utility-scale battery energy storage systems (BESS)

Utility-scale battery energy storage systems (BESS) are the enabling infrastructure that will support the continued growth of renewable energy sources such as wind and solar, essential to the UK's stated target to reduce carbon emissions. They store excess energy generated by renewable energy sources and then release that stored energy back into the grid during peak hours when there is increased demand. BESS also provide Frequency Response services to National Grid whereby batteries import and export power with the aim to keep real-time supply and demand in near-perfect balance while also protecting against unexpected outages of major power plants.

Performance Highlights

Net Asset Value (NAV) as of 30 June 2022 rose to £785.4mn or 145.11p per share (vs. 116.86p as at 31 December 2021 and 109.89p as at 30 June 2021).

Full Operational Dividend Cover1 of 3.5 pence dividend was achieved in H1 2022.  This is equivalent to a 4.5% annualised dividend yield based on the closing share price on 30 June 2022.   The Board reaffirms a target dividend of 7.0p for 2022 and expects full Operational Dividend Cover for the full year. The Company will balance future dividend target levels with increases in Operational Dividend Cover.   A new Prospectus was published in May 2022 with an initial equity raise of £150mn which was oversubscribed. The share capital raised, combined with the debt facilities both available and anticipated in the form of the accordion, will allow the Company to execute on the deployment of most of its pipeline of Battery Energy Storage Systems, (BESS) which is expected to see total operating capacity reach 1,597MW.   A first drawdown of £10mn was made from the £180mn total debt facility[4] in May 2022, as deployment into BESS under construction progressed in the period. The Company expects to fully utilise the existing £150mn capex facility by Q1 2023 and has begun looking at extending the facility in the second half of 2022 through the uncommitted accordion already in place.

Operational Highlights

The underlying investment portfolio generated revenues[5] of £30.1mn (June 2021: £24.9mn) and EBITDA of £22.7mn (June 2021: £22.4mn).   While Operational Capacity remained unchanged at 425MW in the six months ended 30 June 2022, the Company is pleased to report that as of 31 August 2022 two additional projects have been commissioned: the 35MW project at Arbroath and the 40MW Stairfoot project.   As flagged in the full year results, assets under construction have continued to experience delays with equipment deliveries and grid connections being experienced industry-wide. The future projections of the pipeline later in this report include these impacts.   The Company also expects the commissioning of the 50MW Enderby project and the 40MW Coupar Angus project in the coming days which will increase Operational Capacity further.  In addition, further capacity currently under construction is expected to become fully operational in the coming months. Total Operational Capacity is expected to reach 690MW by the end of 2022.   During the first half of 2022 four out of five, or 85MW out of 120MW, of the projects contracted in Enhanced Frequency Response (EFR) reached the end of their 4-year contracts. These projects have subsequently entered Dynamic frequency response services, resulting in a like for like increase in revenues. The remaining 35MW project saw its EFR contract end in July 2022 and was also successfully submitted into the newer services.   Work has begun to increase the duration of each of the EFR projects, most to two hours, with construction completion planned for between Q4 2022 and Q1 2023, as detailed in the Investment Manager's report.

2. CHAIR'S STATEMENT

On behalf of the Board, I am pleased to present the Interim Report and Accounts of Gresham House Energy Storage Fund plc (the "Fund" or the "Company") for the six-month period ending 30 June 2022.

Summary

The Board is delighted that the Fund continues to thrive and scale up. 

Strong share price performance has been underpinned by significant uplifts in the Fund's NAV per share which have largely been driven by upward revaluations of projects as they go from being fair valued at cost to a fair value using a net present value basis in accordance with the Company's valuation policy. These valuation uplifts reflect the attractive underlying internal rates of return (IRRs) of our projects at the time they are acquired. We look forward to this theme continuing to drive value as the current pipeline is built out over the coming quarters.

Following shareholder approval of changes to the Company's Investment Policy, the Company is now permitted to invest up to 30% of its gross assets internationally. This important change allows the Manager to pursue opportunities beyond British shores as the BESS market opportunity expands globally with energy security high on the agenda. Exciting as it is, this expansion will be approached in measured steps, to ensure that the risks of different geographies are well understood. The other changes to the Investment Policy approved by our shareholders will provide the Manager with welcome flexibility and ability to operate and execute transactions in a more streamlined and efficient manner.

The Fund's projects also continue to generate above budget cash returns as market fundamentals remain healthy. The key factor driving the revenue generation potential of batteries continues to be the rising penetration of renewables, combined with the falling contribution from gas-fired and coal-fired generation. In this vein, it has been positive to see renewables reach a new record share of electricity generation in the UK in Q1 2022 of 45.5%.  The new UK Government is  expected to continue to support renewables and decarbonisation in order to reduce reliance on fossil fuels and accelerate the UK's strategic agenda towards energy self-sufficiency.

Meanwhile a record 11GW of renewable capacity has been contracted in the fourth Contracts for Difference (CfD) subsidy regime's Allocation Round (known as AR4). 7.6GW of this capacity will be offshore and remote island wind which was contracted at a new record low price of £37/MWh (in 2012 real prices). This, along with other capacity already contracted in AR3, could take UK renewable penetration above two-thirds within the next five years, which might drive significant increases in required BESS capacity.

Whilst market fundamentals remain healthy, the markets are clearly becoming more volatile as inflation grips economies, as interest rates rise and as the geopolitical backdrop turns more unstable. In addition, supply chain challenges remain following two years of COVID-19 related lockdowns and other restrictions, including increased transport costs. The Manager is working hard to build resilience against future disruptions by taking advantage of our scale and expertise and by extracting maximum value from our operational portfolio and construction activities. 

It is clear that Energy Storage is a business strongly driven by the use of data. The Manager's team continues to build on its digital platform, first mentioned at our Capital Markets Day in May 2022, to take advantage of this by combining the huge amounts of market, commercial, technical and other information to which it has access to optimise project designs and revenue generating operations. We look forward to sharing more on this topic shortly.

Last but not least, the Manager continues to progress its ESG (environmental, social and governance) considerations. The Company is committed to reporting against Diversity & Inclusion (D&I) standards and Task Force on Climate-related Financial Disclosures (TCFD) at the next annual report, as well as progressing internally motivated initiatives, with a current focus on a battery supply chain audit and the long-term recycling of batteries.

Fund performance update

The NAV rose significantly in the six months to 30 June 2022 to £785.4mn up from £511.7mn at 31 December 2021. NAV per share increased by 24% to 145.11p, driven mostly by gains from the revaluation of projects previously held at cost now being valued based on the Net Present Value of future cashflows in accordance with the Company's Valuation Policy. This valuation uplift primarily reflects the attractive IRR of projects relative to the Company's weighted average discount rate as well as the benefit of funding incremental projects with debt financing.

The Fund has continued the strong financial performance of 2021 into the first six months of 2022, achieving Operational Dividend Cover[6] of 1.18x (FY 2021: 1.32x). This has been achieved despite an increase in gross dividends paid (due to the increased share count following the Company's equity issuance in May 2022) and while not yet benefitting from operational earnings from the projects that this equity capital has funded. The latter is set to change with operational capacity of the underlying portfolio increasing by 75 MW to 500MW since the period end, as of 31 August 2022.  Further capacity of 240MW is expected to be added in the remainder of 2022, bringing the anticipated operational capacity of the portfolio to 690MW by the end of 2022.

Performance has been underpinned by high prices earned from frequency response services, and from Dynamic Containment (DC) in particular. The volume procured by National Grid ESO has exceeded their forecast levels at the start of 2022, while delays in commissioning new BESS projects in general has resulted in a tight supply and thus high prices. We do expect the frequency response market to become saturated across all contract periods (each 4 hours long) on most days in H2 2022 as our own and other capacity edges the market into oversupply for this service, as the Manager has long expected and predicted. 

Commissioning of our pipeline projects, combined with battery duration extensions at the projects that were previously in EFR contracts, is increasing the revenue-generating potential of the portfolio over the second half of 2022. This is expected to offset expected declines in frequency response service market revenues. Importantly, the Manager is confident that the portfolio will earn revenues at or above the level assumed in our valuation models which underpins the Company's NAV.

Fund strategy and market positioning

In Q2 2022 the Company received shareholder approval for amendments to its Investment Policy. The purpose of these amendments is to carefully position the Company to capture the growth emerging in Overseas Jurisdictions[7] and to drive incremental value for shareholders, by seeking permission to:

·    Invest in Ready-to-Build Projects (up to 10% of GAV[8])

·    Invest in BESS projects in Overseas Jurisdictions (up to 30% of GAV) with or without co-location arrangements[9]

·    Acquire land in connection with BESS projects in the portfolio, and

·    Combine equipment and construction loan buckets into one (combined limit up to 25% of GAV)

The Investment Policy changes will allow the Manager to deploy incremental capital into exciting opportunities in new markets, diversifying revenues and risks whilst maintaining the same focus on the fundamental wholesale market dynamics enjoyed by our BESS projects in the UK. The ability to buy land gives the Manager the opportunity to improve long-term project returns, while the other changes above give the Manager a greater degree of flexibility to execute projects as efficiently as possible.

Capital Markets Day

On 4 May 2022, the Manager hosted its inaugural Capital Markets Day. Over 200 participants registered for the event, which was hosted online and recorded. We appreciate the support of our growing investor base and deepening analyst interest as we continue to provide insights into the Company's business model and how the Company creates shareholder value.

Fundraising

The Company issued a Prospectus in May 2022 for the issue of up to 400 million new shares. Following the publication of the Prospectus, the Company raised £150mn through the issue of 103 million shares at a valuation of 145p per share. 

The Board and Manager were encouraged by the strong uptake of the Company's shares with demand significantly exceeding the share issuance, and we are thankful to our shareholders for their support of the share offer.

Share price performance

During a turbulent time for the UK and global economy, it has been gratifying to see the continuing appreciation in the Company's share price, in particular the continuing premium to NAV per share. We would like to think this might be in part because of our operational track record, the Manager's prudent management of capital and acquisition strategy and the sector's return characteristics which are uncorrelated to broader markets.

The Share Price Total Return since IPO reached 86.9% through to 30 June 2022 (FY 2021: 51.5%) and 23.3% for the six months to 30 June 2022. By contrast, the FTSE all share index Total Return was -4.6% for the six months to 30 June 2022.

ESG - Sustainability

The Manager is working hard on its commitments to integrate sustainability metrics into its project evaluation and operations. The Manager has committed to seven core areas of focus which are highlighted in the Sustainability Report on page 15.

It is worth drawing out the highlights:

-     a commitment to comply with all applicable standards starting with Task Force on Climate-Related Financial Disclosures (TCFD) (which include emissions) and Diversity, Equity & Inclusion disclosures in the next Annual Report and compliance with SDR (and potentially SFDR, the EU equivalent) once the UK standards have been finalised

-     a commitment to proactivity and integrating guidance and feedback from our investors

-     completion of a third-party supply chain audit of the battery market

-     commitment to developing a working policy on battery recycling

The Board is clear on the importance of aligning the ESG activities and measures with the Company's purpose, and that is an active area of discussion between the Board and the Manager.

Outlook

The outlook for the Company remains exciting and the Manager remains focused on future growth opportunities. International markets are starting to open up for BESS investment, with regulatory changes and growing renewable penetration echoing the development seen in the UK, and the Fund is ready to take advantage of this opportunity.  However, over the next two years, the Manager will primarily deliver against its UK and Ireland pipeline. Despite some delays, our ambitions are broadly on track. In summary, the Manager fully expects to continue to build on the pipeline, both domestically and abroad. 

Our scale remains a competitive advantage that we continue to exploit. It allows the Manager to continue investing in its team, to extract synergies and to capture the interest and attention of even the largest battery and other critical equipment suppliers. That in turn allows the Manager to secure timely supplies, even in the current tight market for batteries. 

Staying focused on near term delivery goals, the Company looks forward to the commissioning of the next suite of investment projects and markedly increasing the revenue generating potential of this portfolio as the MWs and MWh scale up. 

Even in the face of the impact of the geopolitical tensions impacting the global energy markets, the Company remains in a strategic sweet spot of opportunity.

3. INVESTMENT MANAGER'S REPORT

Gresham House Asset Management Limited (GHAM) is wholly owned by Gresham House plc (GH), an AIM-quoted specialist alternative asset manager with a market capitalisation of £302mn as at 30 June 2022. Gresham House provides funds, direct investments and tailored investment solutions, including co-investment, across a range of highly differentiated alternative strategies. GHAM's expertise includes strategic public equity, private equity, forestry, housing, new energy and infrastructure.

Portfolio and pipeline overview

In the first six months of 2022 the Company grew its overall portfolio through the acquisition of the project rights relating to Elland (50MW), York (50MW) and West Bradford (87MW) taking the total portfolio capacity to over 1GW as of June 2022 (December 2021: 850MW).

The average battery duration has also increased. New projects will be built with at least 1.5 hour batteries, and in addition, duration extensions are underway for 120MW of assets previously contracted in EFR, which will take the duration for most of those projects to c.2 hours.

The operational capacity of the Company's investment portfolio remained at 425MW across 17 projects as of 30 June 2022 (31 December 2021: 17 projects and 425MW), although it increased to 500MW as of 31 August 2022 with the energisation of Arbroath and Stairfoot. Coupar Angus (40MW) and Enderby (50MW) are expected to be energised in the coming days taking total operational capacity to 590MW. Delays in both equipment availability and connection dates have caused a number of delays to commissioning dates meaning several projects which were originally planned for H1 2022 are now expected in H2 2022.

By the end of 2022, the Company is expected to have 690MW of operational capacity as West Didsbury (50MW), and Penwortham (50MW) commission, resulting in a 62% increase in operational capacity from the half-year stage.

Planning and EPC agreements for the project extensions on the assets previously contracted in EFR (Glassenbury, Cleator, Tynemouth, Port of Tyne and Nevendon) have progressed well and planned outages are expected around the end of the year. Batteries for these project extensions are also ordered. Large total battery orders from the Fund in the last 12 months have resulted in favourable pricing from our suppliers considering the underlying increase in raw material costs. This is a good example of how the Fund is able to benefit from its scale.

In addition to the portfolio and pipeline shown in tables 1 and 2 below, there is a large yet-to-be-announced pipeline of projects at various stages of negotiations and/or development both in the UK and overseas. Further updates on this incremental pipeline will be announced in due course.

As at 30 June 2022, the valuation of the portfolio was £565mn (FY 2021: £389mn, HY 2021: £323mn), a 45% increase since the beginning of the year. The valuation primarily reflects 425MW in operational projects (FY21: 425MW), 487MW of assets in-construction (FY21: 150MW) and cash in hand. The assets in-construction are expected to commission within nine months of 30 June 2022.  The MW capacity of projects valued above cost has increased by 337MW in the last six months, made up of the three acquired projects in the period (Elland, York and West Bradford totalling 187MW), plus Grendon 1 (50MW) and Melksham (100MW).

Fund performance

The first half of 2022 has been another exceptional period for the Company's investments as they continued to benefit from high pricing in Frequency Response services driven by National Grid's demand for these services continuing to exceed the supply (in MW) of BESS capacity.

This has enabled the portfolio to achieve record cash generation and Operational Dividend Cover of 1.18x[10].  

In May 2022, the Company raised £150mn in equity to fund new projects moving into construction. The placing was significantly oversubscribed but the Company exercised capital discipline by not accepting more funds than currently required. This placing, together with the available debt facility (£180mn plus up to £200mn in an uncommitted accordion facility), will now provide the capital for the majority of the existing pipeline shown in Table 2 above.

The Company's share price has continued to outperform equity markets with the Share Price Total Return for the six months to 30 June 2022 reaching 23.3% compared with -4.6% for the FTSE All Share Index, supported by the historic and anticipated NAV growth as pipeline sites are acquired and commissioned. 

NAV per share growth in the first half of 2022 was 24.2% to 145.11p (FY 2021: 116.86p) and was itself largely driven by the revaluation of in-construction assets previously held at cost, as well as strong cash generation from operational assets. We continue to focus on accretive acquisitions with returns above the weighted average discount rate to drive future shareholder value creation via NAV Total Return.

With the growth in NAV, AIFM fees are reducing as a percentage of NAV due to the tiered fee structure (fees on incremental NAVare lower above certain thresholds) helping to keep costs down. Annualised ongoing charges in the period were 1.16% based on the weighted average NAV for the six months to 30 June 2022 (FY 2021: 1.23%, FY 2020: 1.26%), which is among the lowest compared to other listed funds in the market.

Portfolio performance

The portfolio continued to deliver exceptional returns in H1 2022, following a strong year in 2021. Revenue from underlying assets for the period was £30.1mn, up 20.6% on H1 2021 (£24.9mn) and up 13.6% versus H2 2021 (£26.5mn). EBITDA from underlying assets was £22.7mn (H1 2021: £22.4mn, FY 2021: £42.5mn)

Revenues have remained high on the back of high Frequency Response service pricing due to the continued undersupply of MW capacity delivering Dynamic Containment (DC) during the period, compared with the amount procured by National Grid ESO. We expect Frequency Response pricing to begin to drop in the second half of the year as additional BESS capacity becomes operational - see the Market update section for further details.

 Frequency Response services

In total, Frequency Response (FFR, EFR, DC, DM and DR) made up 88.6% of total revenues with DC contributing over half of the revenues at 52.8% of total revenues (2021: 59.6%).

The contribution from EFR fell during the period due to assets coming to the end of their contracts, with only Port of Tyne remaining in EFR at the period end and this contract came to an end in July. Each of the former EFR assets (Glassenbury, Cleator, Tynemouth, Nevendon and Port of Tyne) have now moved into the available services with DC and Firm Frequency Response (FFR) being the focus, delivering an uplift in revenue per MW for the portfolio. These assets will undergo a duration extension to allow them to be better equipped for the trading environment that the sector is moving towards.

Due to the growth in UK BESS capacity and limited overall Frequency Response requirement from National Grid, we had expected that the market would reach oversupply during the first half of 2022. However, delays to construction across the sector and higher demand than forecast have meant this anticipated saturation has not yet occurred but is naturally expected to happen soon as projects do commission.

The Manager has also made the most of relative opportunities in FFR and DC (the two largest end market in Frequency Response), maintaining a greater exposure to FFR in H1 2022 (26.2% of revenues) than in H1 2021 (3.9%), as it has offered better returns.  

The higher procurement by National Grid ESO of DC, in particular over the spring/summer versus their own forecasts has meant saturation has been delayed and pricing has therefore remained high during the period. The Manager is particularly pleased to have been able to maximise upside by being in the DC service at times of peak pricing only and generating better revenues in FFR and trading the remainder of the time.

Also supporting strong DC revenues at peak times was a further change in National Grid ESO's pricing and procurement methodology for DC in April 2022 (following the change to 4-hourly contracts in Q4 2021) in allowing for higher price caps in DC (previously limited at £17/MWh) which then led to increased pricing volatility and higher peak prices. 

This higher pricing manifested most impressively in June 2022 when National Grid ESO required significantly higher volume than planned, translating into over £7mn of revenues for the month for the underlying portfolio, as shown in the chart on page 8. High prices have continued through July and into August; however, we are now seeing more periods of low DC prices.  Based on current project commissioning timelines we are anticipating significantly higher operational capacity by the end of the year which will drive more market saturation and our transition to trading as this begins to offer better returns.

 

Capacity Market (CM) contracts

As announced on 28 February 2022, the portfolio secured a significant volume of record high-priced CM contracts in the auction held in February 2022. Initial expectations for these contracts were for them to add over £108mn of revenue over the life of the assets. As these contracts are CPI linked for 15 years, this amount is now likely to be much higher given recent inflation figures. The first of these contracts to start will be 112MW of 1-year contracts starting October 2022 which cleared at £75,000 per MW, driving a further source of additional revenues in H2 2022.

 

Cost focus

In addition to maximising revenues, we have been focused on cost savings throughout the construction and operational phases of these assets. The size of the Gresham House team has grown significantly over the past 12 months as we look to bring more resource for key functions from transaction execution, asset management, operations and maintenance and project delivery in particular.

The limited pool of insurers to date has meant insurance for projects remains relatively expensive across the sector. To combat this, we have been implementing additional safety measures across our sites where possible and are working with insurers to cover off areas of perceived risk. The work is also feeding into site design for new assets to ensure reduced risk and lower insurance premiums. We are hopeful of reducing rates as the latest safety measures can be demonstrated to reduce risk to insurers. 

 

Market update

The following section provides insights from the Manager on the recent performance and outlook for the end markets the Fund participates in, rather than a report on its own performance.

i)          Frequency Response services

Frequency Response has been dominated by Dynamic Containment since its launch in October 2020; however, additional services have been launched during 2022 completing the suite of services known as Dynamic Frequency Response services first anticipated in National Grid ESO SNAPS plans established in 2017.

These services consist of Dynamic Containment (DC), Dynamic Moderation (DM) and Dynamic Regulation (DR), each of which provides a different power response for a given frequency deviation - see the RH chart. Each of these services is now procured separately for Low (export) and High (import) - each type of service is therefore further denoted by an L or H respectively after the service name.  

DCL was the first to launch in October 2020 with DCH arriving in November 2021, DRH and DRL began in April 2022 with DMH and DML completing the set in May 2022. It is expected that Firm Frequency Response (FFR) will eventually be phased out, most likely in early 2023.

Each of the new services has different operating parameters resulting in a different level of battery cycling. DC is the least onerous and DR the most. Longer duration batteries benefit further as they are less stressed in this service. DR actually has a longer duration design requirement due to the high level of cycling required of the batteries and as such is not feasible for <1 hour BESS.  Due to the relatively low volume requirement from National Grid ESO for DM and DR to date (each c.10% of DC) DC has remained the primary service of interest.

Demand has been greatest in DCL. The higher requirement for the Low service reflects the fact that the primary need from National Grid ESO is on the export side i.e. for protection from "loss of load" such as the unplanned outage of a generator at which time the frequency collapses if not mitigated.  

The DCL service has evolved in three key phases since launch in October 2020 (as depicted in the charts below). The first of these represented the initial design of the service, procured in 24 hour blocks day ahead with a price cap of c.£17/MWh and flat volume requirement of 1,100MW each day. During this time, the market participants all enjoyed consistent revenues at £17/MWh due to the market being undersaturated.

Phase 2 began in November 2021 when procurement was changed to 4-hourly blocks (EFA blocks) on a day ahead basis. Along with this came varied intraday volume requirements by EFA blocks. This drove greater volatility in DC revenues with volume requirements generally falling in many EFA blocks leaving some periods saturated, even clearing at £0/MWh in some instances where no volume was required. This also brought greater upside with price caps in some periods moving up to £48/MWh. These changes generally resulted in marginally lower average pricing than in Phase 1 but if combined successfully with FFR, it could lead to an increase in revenues overall as we proved in February 2022 when the portfolio had a new record month.

 

Phase 3 began in April 2022 when National Grid ESO announced procurement of MWs against a continually changing "buy curve", driven by volume requirements from National Grid ESO's modelling. The result of this was to add volatility of price caps (now changing dependent on volume available) alongside the previously added procurement volume volatility. This period saw National Grid ESO's DCL volume requirements begin to increase as the UK headed towards spring and summer and, with it, higher solar renewable generation. Higher solar generation results in less gas generation which makes frequency prone to dropping more quickly if a power station comes offline unexpectedly, hence requiring more batteries to respond.

The net result of all the above is a much more merchant Frequency Response market. Prices have been able to reach >£100/MWh during this phase, and on occasion have also fallen as low as £0.5/MWh. The increased volatility can be seen by the frequency and magnitude of the spikes occurring from April 2022 in the charts. Through the six months to June 2022, overall National Grid ESO has procured higher volumes in DC than forecast at the start of the year, and this allowed pricing to remain extremely high on most days as the service remained undersaturated for longer despite a growing number of MWs competing for the service. 

The Manager analyses "headroom", the difference between maximum volume required versus volume actually procured, as the best indicator for how close to saturation the market is. This data is from National Grid ESO. In June 2022, headroom was 122MW in DCL with EFA 5 highest at 254MW. This has fallen in July 2022 to 72MW on average, with EFA 5 highest at 138MW of headroom.  

As more BESS projects commission across the industry, the headroom will continue to shrink until it is disappears and the market is oversubscribed the majority of the time. The Fund's own pipeline is likely to cause this market to become oversubscribed in 2022 given the volumes set to commission.

Once the DC market is saturated, contract prices will be influenced by the next best revenue opportunity which is likely to be trading i.e. batteries will step away from offering DC and just trade once pricing falls.   

This will support DC prices as supply comes out but alternative revenues from trading will primarily vary with battery duration. Longer duration assets can generate much greater revenues from trading. For example, a half hour battery looking to trade may need to position itself at half its MW-capacity to emulate a 1-hour battery, to overcome potential overheating when operating as a 30 minute battery, limiting its trading revenues materially.

As we get closer to the point of saturation in Frequency Response markets, we will begin to see greater emphasis on trading either through setting of Frequency Response prices or by moving to trading in the wholesale market and Balancing Market (BM) instead. This is why understanding, and being ready for trading, is key to any investment.

 

ii)         Trading/Merchant markets

Despite the limited exposure to trading from the portfolio in the period, due to the focus being on high Frequency Response, there have been continuing developments which have contributed to a strengthening trading environment for BESS.

Gas prices reached record levels in December 2021, on the back of high demand, low storage levels and fears around disruptions of Russian gas supplies before Russia invaded Ukraine in February 2022. After the invasion gas prices rose further reaching a record high.

Gas prices have remained high and are having a direct impact on electricity prices and volatility, with the price of gas generation often setting the electricity price - a topic capturing the public's and politicians' attention due to high cost of electricity, as the uncertainty of gas supply across Europe remains.

In the longer term we expect for this to return to more 'normal' levels as higher levels of renewables and alternative supplies bring supply and demand back into balance at lower price levels, but in the short term we may experience more extreme pricing, particularly over the winter during higher demand periods.

This, in part, has led the UK Government to launch the Review of Electricity Market Arrangements (REMA) looking to reduce the cost of electricity to consumers, with further information provided later in this report. The wider political response to the rising gas costs has been to focus efforts on the rollout of renewable energy which supports the case for increased demand for BESS.

However, while BESS is a much cheaper alternative power to fossil fuel generation in providing flexibility to manage intermittency, there is simply insufficient BESS capacity to manage current levels of renewable generation and so to meaningfully reduce our reliance on gas. It is therefore likely that, no matter where gas prices head, volatility from renewable generation will continue.

Availability of Russian gas across Europe has driven concerns over energy security, particularly looking forward to the winter. To make matters worse, France has an increasingly unreliable Nuclear fleet. Given the reliance on Nuclear in France the loss of generation has led to the need to import power from other countries. This resulted in April 2022 being the first month of net export through interconnectors in Great Britain (GB) since 2017.  Average interconnector imports in GB were 2.9GW in February 2022 and have since fallen to 2.5GW export in June 2022 effectively creating a c.5GW additional demand requirement to be covered by National Grid ESO.

The combination of high gas prices with increased demand has led to high peak energy prices, whilst high renewable output through the summer has also created negative prices at times, resulting in much greater daily energy price spreads than typically seen during a summer.

The system price chart demonstrates the growing spread between low and high prices with the current spreads in July and August 2022 significantly above previous norms for that time of year and more aligned with the high winter volatility we have seen in the last two winters.

All taken together this presents a favourable trading environment for BESS assets. As system demand increases, and as we head closer to winter, the current market drivers of gas prices and interconnector exports are likely to open up the potential for extreme pricing on particularly high demand days. With prices for Frequency Response services (ignoring any uplift from trading opportunity) expected to begin falling, trading is likely to become the main area of focus for the portfolio.

iii)        International markets

Consistent with the investment methodology used for UK and Ireland assets, the core focus for international investments will be on the evaluation of each market's underlying wholesale market dynamics. We will also be looking for markets with high renewable penetration and/or growth with present or expected wholesale volatility which offers returns in line with stated ranges. Any ancillary services, subsidies or 'locational' opportunities at different locations within any given market will be treated as an additional but short-term benefit, aligning how we think about investments abroad with how we think about them in the UK.

Our team are working hard to evaluate new opportunities overseas and review the available markets to focus on the right areas for investment. There are a number of deals in progress already and we hope to notify shareholders in due course of additional pipeline sites to be added. The scale of opportunity overseas is significantly bigger than the UK market and whilst we remain committed to investment in the UK, and indeed have a considerable pipeline of assets in the UK already, now is the right time to be looking for opportunities to enter international markets, relatively early, in the same way we did in the UK.

 

Construction update

The Manager has experienced challenges energising new BESS projects, in common with other BESS players. A summary of the most significant issues and their current status is shown below:

i)          High overall demand for renewables and BESS: Impact is ongoing

There continues to be huge demand for new projects as a function of the investment appetite of both institutional investors and major corporations (such as the oil majors who are increasingly involved). In the context of BESS, this is creating tight supply chains for inverters, lithium-ion batteries and other electrical components as well as longer lead times. This means contractors are worried about potential higher prices during construction and are increasing their "risk" margins (essentially charging a higher profit margin to protect against unexpected cost increases). Our key mitigation is scale which ensures we have access to equipment and a stronger negotiating position than our competitors which allows us to manage price increases. We are also increasingly procuring components directly, which reduces the impact of "margins being charged on margins" by contractors.

ii)         General inflation and weakening sterling: Impact is ongoing

Higher general inflation and a weak pound is leading to higher labour costs and costs of components sourced abroad. This is also driving higher 'risk' margins from suppliers.  Here, our mitigation is to increasingly source works on an EPCm basis to split out costs in controllable and transparent work packages and proactively manage each of these to minimise risks.

iii)        Commodity prices:  Negative impact turning positive

While we have yet to see significant benefits from this, various commodities and other costs have fallen sharply in recent months. This includes prices for iron-based products, concrete and copper as well as shipping costs.  Debottlenecking of ports, all time high investment in new containers and other shipping and a sharp slowdown in China's housing market are likely to be among the drivers.

iv)        Grid connection challenges: Impact is ongoing

The large number of new grid connections is creating challenges for the grid companies which feeds into our portfolio projects. Capacity is now tight and therefore new capacity has to wait for reinforcements elsewhere in the network. This does not affect projects already in construction as the ability of a new project to connect is studied carefully before a grid connection offer is made.

The challenge for projects in construction is more practically linked to a lack of adequately experienced engineers at the Distribution Network Operators (DNOs) and in all likelihood impacting National Grid as well.  Mitigation here is challenging: engaging positively with the counterparty on the one hand or making complaints (including to Ofgem) are limited remedies for late construction programmes. Further, regulations do not help much: DNOs and National Grid have next to no liability for delays to connections and have a huge amount of time to turn around grid connection offers (pre-construction) or design submissions (during construction). This, combined with the intrinsically intricate nature of the work, the need for safety and a workforce which has retired many of their best staffers and recruited too few over the COVID-19 lockdowns is leaving the industry in a challenging position. Fortunately, some pragmatism is rising to the surface unlocking some delays.

We are factoring in these delays, which are affecting all participants in the market, into new construction programmes and are hopeful that further significant delays at most projects can be avoided. 

The Manager does have two key mitigants but as these are commercially sensitive, they cannot be disclosed here.

 

Valuations and NAV

NAV per share[11] has risen from 116.86p on 31 December 2021 to 145.11p on 30 June 2022. This equates to a NAV Total Return of 27.2% over the last six month interim period.

The largest contribution to NAV growth came from the revaluation of projects previously held at cost, representing £61.2mn (FY 2021: £38.0mn) or 12.12p per share gain. The portfolio valued on a Discounted Cash Flow (DCF) basis consists of 425MW of operational projects as per Table 1 on page 6 and 487MW of in-construction assets. 115MW of projects are held at cost, these projects are under construction with Share Purchase Agreements signed but with completion subject to Provisional Acceptance Certificate issuance. These projects are Coupar Angus (40MW), Arbroath (35MW) and Stairfoot (40MW) with the latter two being operational and Coupar Angus expected to commission very shortly.

The value of the new CM contracts awarded to the Company's projects in the February 2022 auction has also benefited the NAV with a 6.68p per share (£30.6mn) contribution during H1 2022. The remaining uplift from the new CM contracts will come through the revaluation of remaining assets in H2 and once the construction premium is removed from discount rates when assets become operational.

 

Net issuance from equity raised above NAV in May 2022 contributed 2.32p per share to NAV, whilst working capital after deduction of fund costs, transaction costs, debt costs and dividends paid added 0.10p per share to valuations.

Third party revenue forecasts increased substantially in the period following relatively low forecasts at the year-end (which reflected the expectation that DC prices would fall to very low levels). The latest curves reflect the current market conditions of high DC prices on the back of higher volume procurement from the ESO as well as greater trading opportunities heading into the next winter. These therefore provide a short-term uplift in revenues forecasted, whereas the longer term projections remain consistent with previous quarters. The total impact of third party revenue forecast changes in the period was £30.9mn or 6.06p per share.

There have been no changes to the discount rate methodology in the period. The weighted average discount rate is 10.79% for the portfolio (December 2021: 10.77%). The weighted average discount rate for operational assets was 10.55% (2021: 10.57%) whilst in-construction assets had a weighted average discount rate of 11.00% (2021: 11.35%) having fallen due to the addition of CM revenues to the model.  

The main assumption changes for valuations came from updating the inflation rates, with a short-term increase in inflation to 7.5% in 2022, 4.5% in 2023 and falling to 2.5% from 2025. The impact of the update was an increase in valuations of 3.88p per share. We believe our current inflation assumptions are conservative. We will continue to monitor developments in the UK and potentially revisit inflation assumptions ahead of the year end. An increase in inflation rates is expected to increase valuations further.

Valuations by asset can be found in the notes to the financial statements in Note 9 with sensitivities performed on the discounted cash flow modelling for the portfolio shown in Note 15.

 

Regulatory update

On 18 July 2022 we saw the release of two significant energy market reports, the first being the launch of the government's Review of Electricity Market Arrangements (REMA) and the second being National Grid's Future Energy Scenarios (FES) Report for 2022.

REMA is a major review into the GB electricity market design with the aim to ensure cost benefits to customers in the long term. There are several proposals being considered in the review with the key areas of focus for BESS being:

·    Wholesale Markets: first, the introduction of Locational Marginal Pricing (LMP) or 'Nodal' pricing; second, the potential decoupling of the cost of electricity from fossil fuels; and third, changes to the design of the Balancing Mechanism

·    Reforms to the Capacity Market to support low-carbon, flexible technologies which contribute to energy security

·    Review of Contracts for Difference (CfD) and how to incentivise the deployment of renewable generation

REMA is likely to take several years to be fully completed. The deadline for consultation submissions is 10 October 2022 and we are in communication with the relevant parties to get further clarity and feedback on the proposals including ongoing conversations with National Grid ESO on more specific topics coming from REMA.

Given that the build-out of cheap renewables and batteries is a key target for the UK Government and National Grid ESO, and the acknowledgement for the need to encourage more low carbon flexibility to cope with this, we anticipate the net impact of changes to be neutral to positive for the BESS industry. The move to Nodal pricing (which will in any case be at least five years) may present opportunities for greater locational volatility and pricing opportunities for well positioned assets and any changes to CM auctions aimed to encourage BESS, should also be positive.

The Future Energy Scenarios (FES) report for 2022 released by National Grid ESO, was released in tandem with the REMA report. FES 2022 aimed to provide a roadmap for decarbonising energy usage in GB. In each scenario there is a heavy reliance on the further rollout of renewable generation. In all scenarios the ESO significantly increased the amount of storage they expect to see and how early it is deployed. BESS is expected to become the largest share of storage capacity in all scenarios by 2050. The ESO forecasts growth in BESS requirements from 1.6GW in 2021 to 20GW in 2030 and 35GW by 2050 under their 'Leading the way' scenario. In addition to this they also note the need for policy, regulatory and market environments to change for storage assets in order to bring forward the levels of energy storage expected to be needed on the system with particular consideration for developing revenue streams and stacking of services to support business cases for storage projects.

 

Outlook

Through the remainder of 2022 the core focus of the Manager is to increase the operational capacity and revenue potential of the portfolio by commissioning projects due, with the Company targeting 690MW operational capacity in the portfolio by the year end and over 1GW of operational capacity by the end of H1 2023.

This growing operational portfolio should ensure greater cash generation and support Operational Dividend Cover. We anticipate Operational Dividend Cover to increase progressively in line with projects commissioning and expect full Operational Dividend Cover for the year. Dividend levels will continue to be monitored against the level of Operational Dividend Cover.

NAV growth is expected to continue through the end of the year driven largely by revaluation of projects with Coupar Angus, Arbroath and Stairfoot in particular set to be revalued later in the year once they are operational and fully acquired.

As assets under construction commission, and others in the market also come online, we expect to see the remaining headroom for DC disappear, leading to falling Frequency Response service pricing. This should see longer duration assets focus increasingly on the trading potential available to them. The coming winter may see even greater volatility than in previous years, offering significant trading upside from those assets able to trade. We look forward to seeing our portfolio demonstrate their capabilities in this increasingly merchant environment.

The upcoming upgrades to our previous EFR portfolio will increase the duration of these legacy assets allowing them to trade more freely alongside the remainder of our portfolio and ensuring they are capable of earning the revenue opportunity expected over the short to medium term.

The GB electricity market is likely to experience large scale changes over the medium to long term as plans from REMA begin to be put in place. Overall, we believe the UK Government and the ESO remain supportive of BESS and we look forward to ongoing engagement with them to ensure the full benefit of BESS can be felt by the market and by consumers. We remain confident in the opportunity for BESS in the UK markets and are excited by further opportunities open to the Company overseas following the change to the investment policy during the period.

We are seeing comparable market drivers in numerous overseas markets presenting expectations for growing volatility in merchant markets and a solid revenue base. We remain committed to the investment thesis of the fund and hope to have further information on overseas projects in due course. We continue to develop the expertise and size of the team to appropriately match the opportunities ahead.

 

4.    GRID 2022 Interim Report - Sustainability Report

 

In the 2021 Annual Report and Accounts the Sustainability Report detailed the Company's approach to Sustainability including its focus areas. Having reported on 2021 achievements, the report also pointed to our "Future Objectives" which span the period 2022-2025.  The aim of this Sustainability Report is to update our shareholders on the Company's progress on these Future Objectives, listed below as "Objectives" as follows.

 

1.   Commitment to sustainability (Environment)

Objective

Continue to increase capacity under management to increase GRID's contribution to the decarbonisation of the UK's electricity network and a reliable, low-cost energy system.

Update: This is reported on extensively in this Interim Report. In alignment with the Fund's commercial aims, the Manager remains fully focused on growing grid-connected MW and MWh capacity to make a valuable contribution to Net Zero and related goals.

 

2.   Supply chain management (Social)

Objectives

a.   Update the Supply Chain Policy to fully reflect best practice in the market and the commitments of the Investment Manager.

b.   Have a comprehensive supply chain monitoring and management process in place to assess ESG risks in the supply chain and to ensure the compliance of suppliers with the Supply Chain Policy.

c.   Include sustainability criteria into supplier contract renewal and supplier selection decisions.

d.   Engage with key suppliers to enhance their sustainability processes and reduce the Fund's ESG risk exposure.

Update: The Manager is awaiting the completion of an audit of the BESS supply chain, from raw material production to the final product, commissioned earlier this year which is due in Q4. This will inform the actions required for each of the objectives listed above.

 

3.   Marketplace responsibility: processes, policies and education (Governance)

Objectives

a.   Assess all assets against our Sustainable Infrastructure Framework using the ESG Decision Tool and establish plans to rectify any material risks to create and protect value for shareholders.

b.   Ensure the ESG Decision Tool remains up to date to reflect any enhancements to the sustainable investment processes and sustainability related policies.

c.   Finalise ESG KPIs to monitor and measure sustainability performance of the Fund and report these regularly to stakeholders.

Update: These Objectives are ongoing. There is no significant change to report on this occasion. The ESG tool continues to be a valuable tool to focus the Manager on ESG topics.

 

4.   Climate change and pollution (Environment)

Objectives

a.   Report annual carbon footprint to stakeholders.

b.   Set targets and actions to reduce operational carbon emissions.

c.   Apply full TCFD guidance and report in line with recommendations. 

Update: The 2022 Annual Report will report against TCFD and the Manager, Board and our auditors are all preparing for this.

The Manager is also taking active steps to measure energy losses, through on-site energy consumption or losses through heat as the BESS charges and discharges. The Manager is considering alternative designs to reduce such inefficiencies on future sites. As with Objective 1, there is complete alignment between commercial, operational and ESG goals on the subject of carbon emissions.

 

5.   Governance & ethics: engaged and active ownership (Governance)

Objectives

a.   Identify and work with key industry bodies to drive positive industry outcomes linked to sustainability topics.

b.   Track and report on engagement activities and key outcomes.

c.   Increase community engagement, where applicable, continuing to educate the public on the role of BESS in the UK's decarbonisation ambitions.

d.   Solicit, where practical, feedback from key stakeholders who are in a position to contribute.

Update: The Manager is working with industry bodies as well as key industry stakeholders to communicate on various topics. At the top of the agenda at the moment is the Reform of Electricity Market Arrangements, a consultation launched by the Department for Business, Energy and Industrial Strategy (BEIS). This consultation aims to address the challenges the electricity system faces as the energy transition progresses, as well as exploring various ways of addressing the 'cost of living crisis'. Consultation responses are due in October and the Manager is involved in submitting a set of responses.

In the last period we have also shared a questionnaire with our largest shareholders to identify their own priorities, so that in addition to complying with all reporting standards, we also take on board our investors' insights.

 

6.   Natural capital (Environment)

Objectives

a.   Measure and report on key natural capital impacts and dependencies.

b.   Enhance policies and processes to reduce, restore and enhance biodiversity and other key ecosystem services at asset sites.

Update: The Manager is monitoring developments following passing of the Environment Act which will require all developments to create a biodiversity 'net gain' (currently expected from Q4 2022).

 

7.   Waste management (Environment)

Objectives

a.   Work with contractors to incorporate full lifecycle analysis into BESS design to maximise asset life, reduce the overall carbon footprint of constructing and operating projects, and consider end-of-life use to reduce negative environmental and social impacts of battery production and the battery components including raw materials.

b.   Engage with contractors/suppliers on their end-of-life process development and technology.

Update: The Manager is working to fully understand the responsibilities resting with the importer of the batteries, whose obligation it is to recycle batteries at the end of their life. Due to how the construction of the projects has been contracted, this has generally fallen on the EPC contractor. Nevertheless, the Manager is working to understand these obligations too, in order to understand any indirect impacts on the Fund, as well as the implications of being the importer going forward.

 

5. Principal Risks and Uncertainties

Risk management approach

The Company continues to recognise that effective risk management is critical to enable it to meet its strategic objectives.  The Company has a clear framework for identifying and managing risk, at both an operational and strategic level.  Its risk identification and mitigation processes have been designed to respond to the changing environment in which it operates.  The impact of emerging risks on the Company's business model are also considered and used to make informed decisions, including as to the delivery and evolution of the Company's strategy.  The table below captures those risks that would have the most significant adverse impact on the Company (and the underlying investments), based on their impact and/or likelihood. 

 

Existing risks

 

Risk area	Gross impact	Mitigation	Net impact
Availability of batteries and other critical components.   Residual risk: high (2021 FY: N/A)	Inability of the Company to deploy capital raised into investments due to incomplete or lengthening project timescales.   Price increases for components making investments less attractive	The Company's investments are within SPVs and these are subject to a battery order with a Tier 1 supplier which has been secured.  Due to the size of this order, advantageous terms have been secured.	This will remain an issue in the future, although the size and scale of the Company provides the ability to secure key components.
Emerging business model and impact on revenue streams sourced from National Grid mechanisms.   Residual risk: medium (2021 FY: high)	Adverse changes by National Grid in relation to services contracted by them may reduce the size/scope of income earning opportunities to the Company's investments and potential impact on valuation.   HM Government Energy Strategy moves away from intermittent renewable assets which impact on future growth of the Company.	The Company's investments enjoy several different income streams ranging from BM, Capacity Payments, FFR, TRIADs, and DC as contracted services to National Grid; the Company's investments are able to change which income streams are contracted and ascertain the most advantageous on any given time period: this is continuously monitored by the Investment Manager and optimisation partners.   Due to the progressive decommissioning of other carbon intensive options available to National Grid for managing these services, and the need to support the security of this critical national infrastructure, BESS is expected to form an integral part of transforming the electricity sector in the UK.	Battery energy storage is a versatile asset, and it can perform a variety of roles to manage risk.   There is also the potential to "revenue stack" and gain multiple revenue streams from different services.   The income stream opportunities and usage of battery energy storage systems is expected to evolve over time.
Environmental, Social and Governance: production and recycling of batteries creates risk.   Residual risk: medium (2021 FY: medium)	BESS are manufactured, installed, and operated with the intention of driving the transformation to a low carbon energy supply in the UK.  However, the lifecycle ESG impact of the batteries needs to be considered and minimised.	The supply for battery manufacture relies on high quality global partners who ensure their supply chain does not involve the use of illegally or unethically sourced "rare earth" materials or inadequate labour standards.  This could be mitigated by undertaking reviews of the supply chain.   The recycling of the BESS systems is subject to constant development and research; the importer of these batteries (not the Company or SPV companies) is responsible for their disposal, but the Company will facilitate this to ensure low environmental impact.	Some aspects of this are still evolving over time, especially the end use/recycling of BESS.   The ability of the BESS market to drive a low carbon electricity system needs to be considered versus the other, mainly fossil fuelled, options when considering the overall ESG impact of BESS.  Work will continue to minimise this over time.
Valuation risk.   Residual risk: medium (2021 FY: medium)	The Company's investments are valued using discounted cash flows and assessment of future income streams: these valuations may be materially incorrect or not held at fair value.   The impact of volatile inflation and interest rates may impact upon these valuations.	The Company's investments are impaired if income streams are not as profitable as expected or costs are higher than expected.    Risk adjusted discount rates drive valuation along with the external pricing curves.	The Company utilises a modelling methodology which ensures income streams are discounted using appropriate discount rates dependent on the perceived risks.   The weighted average discount rates are reviewed regularly and the Company believes the valuations are conservative.   A third-party valuer reviews valuations and confirms appropriateness.
Operational and performance risk in the underlying investments leading to loss of value.   Residual risk: low (2021 FY: low)	The BESS investments do not perform in the manner expected (i.e. degradation in performance) or are not optimised in the best commercial manner to capture revenue streams leading to reduction in valuations.   Performance within the SPVs may not meet planning or safety requirements and result in curtailment of operations and loss of investment value.   The portfolio relies on contracts with suppliers to maintain certain key equipment: these suppliers may fail to provide adequate support.	The Company underwent a programme of upgrades to the seed assets to optimise these assets and has ensured that the new assets being invested into are designed in a flexible manner.  The battery duration for the new investments is also considered to ensure fullest flexibility for future operation.   Design and commissioning testing takes place in each investment to ensure all relevant planning and HSE conditions are met.  Fire risk, in particular, is carefully assessed and sites are designed and operated to ensure this risk is as low as practicable.    Cyber security risk is managed via secure systems used by optimisation partners.   The portfolio has a number of alternative suppliers and optimisers to manage risk.	The Investment Manager has substantial experience managing BESS assets and works with leading asset optimisers to ensure assets are designed and operated as expected.    Health and safety performance is rigorously tested and reviewed.
Investment in development and construction projects.   Residual risk: low (2021 FY: low)	The Company invests in projects via loans before and after the projects are owned by the Company.  There is a risk that the project does not complete, and the Company incurs financial loss.   The Company invests in construction projects as part of its investment portfolio.   There is a risk of financial loss or delay of revenue generation.   Late delivery of plant items may lead to delay.	The Company does not invest in speculative project development.  Any investments in projects are carefully assessed and vetted by the Investment Manager: they will have secured certain minimum requirements and are expected to be ready to proceed to construction in a relatively short timescale.	Limited exposure to the Company due to careful vetting and management of project development activities and commercial arrangements with the Investment Manager to manage construction risk.   The Company is usually investing in the advance purchase of equipment which has inherent value and can be used on other projects if needed.
Reliance on the Investment Manager.   Residual risk: medium (2021 FY: low)	The Company relies on the Investment Manager as a key supplier.	The Company has long-term contractual arrangements in place with the Investment Manager, and the Investment Manager has confirmed to the Company that the growth of the Company is a key focus area of the Investment Manager.	The Investment Manager remains incentivised to continue to grow the Company and drive value.   The growth in scale and associated activity supplied by the Investment Manager will tend to increase this risk.
Financing risk.   Residual risk: low (2021 FY: low)	Equity or debt financing is not available and the Company is unable to fund its pipeline of assets.   The Company's investments are subject to banking covenants which could be breached if the Company's investments do not perform as expected.   Higher interest rates will increase the Company's cost of debt.	The Company does not enter into unfunded commitments: all committed pipeline can be funded from existing equity finance or the existing debt facility.   The banking covenants have been carefully modelled by the Investment Manager to ensure they are achievable.	Limited overall impact on deployment of pipeline.   As the Company's investments draw down more debt this risk will tend to increase.   As debt is drawn the Company enters into interest rate hedging instruments to manage this risk.
Tax compliance.   Residual risk: low (2021 FY: low)	The Company is registered as an Investment Trust and must comply with certain tests.	The Investment Manager undertakes the relevant tests each quarter and the Company's tax advisers review this regularly.	None.

 

Emerging Risks

Risk area	Gross impact	Mitigation	Net impact
Emerging technology replaces battery energy storage assets.   Residual risk: low (2021 FY: low)	The Company invests in battery storage projects: a new or disruptive technology might adversely impact on the Company's investments.   Future income streams may be reduced if new entrants have significantly lower marginal costs.	The Company utilises proven technologies with associated Tier 1 supplier warranties and performance guarantees.    The Company continues to review available technologies. It is currently viewed as unlikely that a completely new reliable and cost competitive technology will appear during the lifetime of these batteries and impact on the lifecycle of these batteries.	The Company will also benefit from lower costs and the valuation model assumes continuing cost reductions for replacement assets over time.
Potential equipment shortages if China is subject to sanctions.   Residual risk: low (2021 FY: low)	If China invades Taiwan or takes other hostile measures which cause sanctions, the supply chain of crucial equipment would be disrupted.	The Company has relationships with other non-Chinese suppliers, but they are likely to source components from China.   The Company ensures payments are protected via Letters of Credit to ensure no financial loss.	The Company ensures it is securing key equipment orders in advance.

DIRECTORS' REPORT

The Directors present the Interim Report and Accounts of the Company for the period ended 30 June 2022.

The Directors during the period, including their appointment dates, are set out in the Board of Directors summary on page 23.

Company performance

The Directors have reviewed the performance of the Company throughout the period. Details of the performance of each investment owned by the Company are included in the Investment Manager's Report on page 5.

The Directors and Investment Manager have developed several tools to review ongoing performance. These include ongoing monthly and quarterly dashboards detailing the performance of each investment in relation to the individual income streams expected of each investment and performance against costs.  As the Company deploys capital raised, the Directors have a focus on the underlying investment model for each new investment to ensure it meets the Investment Objectives of the Company.

The Directors are satisfied that underlying performance is being developed in line with expectations: the rollout programme of new investments and upgrades and extensions of investments acquired at IPO is continuing to progress well and has ensured an increasing level of operational performance throughout 2022 so far, which is summarised within the Chair's Statement on page 3.

Financial risk management

The Board believes that the main financial risks of the Company relate to the requirement to ensure the capital commitments of the Company are commensurate with the capital available and the ability of the underlying investments to generate income to the Company to ensure the targeted dividend payments can be paid to investors and total NAV return targets are met. The Board constantly monitors these financial risks.

The Company has the ability to assume up to 50% of gearing and may increase gearing in future ensuring any covenants or associated financial instruments are appropriate for the risk profile of the Company.

Share capital

At the period end, the Company had in issue 541,290,353 Ordinary Shares. There are no other share classes in issue. All shares have voting rights; each Ordinary Share has one vote.

All Ordinary Shares are entitled to receive dividends and interim dividends have been paid by the Company, as shown in the table below. No final dividend has been or will be declared, but the Company's dividend policy of paying four interim dividends will be tabled for approval at each annual general meeting.

Period in relation to which dividend was paid	Announcement date	Ex-dividend date	Payment date	Amount per Ordinary Share	Total amount

Going concern

 

The Interim Report describes the Company's business activities, together with factors likely to affect its future performance and development and an assessment of the principal risks and uncertainties facing the Company. The key risks facing the Company include, but are not limited to, the risks mentioned on pages 17 to 20.

 

As at 30 June 2022, the Company had net cash and cash equivalent balances of £222mn (excluding cash balances within investee companies) and no debt. The Company is a guarantor to the £180mn debt facility (£150mn capex facility and £30mn revolving credit facility) entered into by the Midco in September 2021 which was partially drawn at the period end. It is anticipated that the capex facility will be fully drawn during 2022 and 2023 to purchase equipment and make payments under EPC contracts for pipeline projects.

 

Financial models have been prepared on a conservative base case and on a severe but plausible downside case which show that sufficient cash is expected to be available to the Company to meet current obligations and commitments as they fall due and that the debt covenants of Midco's debt facility are expected to be met. The base case assessment considers the Company's ability to continue in operation under the current planned strategy to fund and acquire the currently committed Exclusivity Pipeline. The severe but plausible downside case scenario assumes a reduction in underlying portfolio EBITDA of 25% to the base case. The downside case also takes account of the availability of mitigating actions available to the Directors, such as reducing discretionary spend and pausing the roll-out of projects.

 

The Directors confirm they have a reasonable expectation that the Company has adequate resources to continue its operations for at least 12 months from the date of signing these financial statements. As such, the Directors have adopted the going concern basis in preparing the Interim Report.

 

Directors' responsibilities

The Directors confirm to the best of their knowledge:

·    the Interim Report and Accounts have been prepared in accordance with International Accounting Standard 34 "Interim Financial Reporting" and give a true and fair view of the assets, liabilities, financial position and profit or loss of the Company, as required by DTR 4.2.4 R of the Disclosure Guidance and Transparency Rules;

 

·    the Chair's Statement and Interim Investment Manager's Report include a fair review of the development, performance and position of the Company and a description of the principal risks and uncertainties, that it faces for the next six months as required by DTR 4.2.7.R of the Disclosure Guidance and Transparency Rules; and

 

·    the Investment Manager's Interim Report and Note 20 to the Condensed Financial Statements include a fair review of related party transactions and changes therein, as required by DTR 4.2.8.R of the Disclosure Guidance and Transparency Rules.

1.    General information

Gresham House Energy Storage Fund plc (the Company) was incorporated in England and Wales on 24 August 2018 with company number 11535957 as a closed-ended investment company. The Company's business is as an investment trust within the meaning of Chapter 4 of Part 24 of the Corporation Tax Act 2010. The registered office of the Company is The Scalpel, 18th Floor, 52 Lime Street, London, EC3M 7AF. Its share capital is denominated in Pounds Sterling (GBP or £) and currently consists of Ordinary Shares. The Company's principal activity is to invest in a diversified portfolio of operating utility-scale Battery Energy Storage Systems (BESS), which utilise batteries and may also utilise generators. The BESS projects comprising the portfolio are located in diverse locations across Great Britain.

These interim financial statements cover the period from 1 January 2022 to 30 June 2022, with a comparative period from 1 January 2021 to 30 June 2021, and comprise only the results of the Company as all of its subsidiaries are measured at fair value.

 

2.    Basis of preparation

Statement of compliance

The Interim Report and Accounts have been prepared in accordance with International Accounting Standard 34 'Interim Financial Reporting'. The Condensed Financial Statements have been prepared on a historical cost basis except for financial assets and liabilities at fair value through the profit or loss. The accounts have been prepared on a basis that is consistent with accounting policies applied in the preparation of the Company's Annual Financial Statements for 31 December 2021.

Where presentational guidance set out in the Statement of Recommended Practice (SORP) 'Financial Statements of Investment Trust Companies and Venture Capital Trusts', issued by the Association of Investment Companies (AIC) is consistent with the requirements of IFRS, the Directors have prepared the Interim Condensed Financial Statements on a basis compliant with the recommendations of SORP. The supplementary information which analyses the Statement of Comprehensive Income between items of revenue and a capital nature is presented in accordance with the SORP.

These Condensed Financial Statements do not include all information and disclosures required in the Annual Financial Statements and should be read in conjunction with the Company's audited financial statements for the year ended 31 December 2021, which were prepared in accordance with UK adopted international accounting standards.

There are no new standards, amendments or interpretations at the reporting date which have been issued but are not yet effective, which could impact the Interim Report and Condensed Financial Statements of the Company and which are deemed to be material for the Company.

 

Functional and presentation currency

The currency of the primary economic environment in which the Company operates (the functional currency) is Pounds Sterling (GBP or £) which is also the presentation currency.

Going concern

As at 30 June 2022, the Company had net current assets of £221mn and had cash balances £222mn (excluding cash balances within investee companies), which are sufficient to meet current obligations as they fall due. The major cash outflows of the Company are the costs relating to the acquisition of new assets and payment of dividends, both of which are discretionary (other than committed transactions). All committed acquisitions at the end of the period are sufficiently covered through current cash reserves and debt facilities. The Company had no outstanding debt owing as at 30 June 2022. The Company is an obligor to the debt facility entered into by Gresham House Energy Storage Holdings (the Midco), which was partially drawn at 30 June 2022.

As such, the directors have adopted the going concern basis in preparing the Interim Report and Condensed Financial Statements.

 

3.    Significant accounting judgements, estimates and assumptions

The preparation of the Condensed Financial Statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amount of assets, liabilities, income and expenses. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to the accounting estimates are recognised in the period in which the estimates are revised and in any future periods affected.

During the period the Directors considered the following significant judgements and assumptions:

Assessment as an investment entity

Entities that meet the definition of an investment entity within IFRS 10 are required to measure their subsidiaries at fair value through profit or loss rather than consolidate them unless they provided investment related services to the Company and are not themselves investment entities. To determine that the Company continues to meet the definition of an investment entity, the Company is required to satisfy the following three criteria:

a.   the Company obtains funds from one or more investors for the purpose of providing those investors with investment management services;

b.   the Company commits to its investors that its business purpose is to invest funds solely for returns from capital appreciation, investment income, or both; and

c.   the Company measures and evaluates the performance of its investments on a fair value basis.

The Company meets the criteria as follows:

§ the stated strategy of the Company is to deliver stable returns to shareholders through a mix of energy storage investments;

§ the Company provides investment management services and has several investors who pool their funds to gain access to infrastructure related investment opportunities that they might not have had access to individually; and

§ the Company has elected to measure and evaluate the performance of all of its investments on a fair-value basis. The fair-value method is used to represent the Company's performance in its communication to the market, including investor presentations. In addition, the Company reports fair value information internally to Directors, who use fair value as the primary measurement attribute to evaluate performance.

An indicator of whether a Company is an investment entity is the existence of a formal exit strategy. Although there is currently no documented exit strategy, the assets have a limited life and are not expected to be held indefinitely.

A further indicator of whether a Company is an investment entity is the expectation they hold more than one asset. Following the sale of the investment in Noriker Power in the year to 31 December 2021 the Company holds one investment directly but many investments indirectly, as there is a portfolio of investments within the Midco.

The Directors believe the Company meets the business purpose criteria to invest for capital appreciation and/or income generation and note that the Company is not required to hold its investments indefinitely.

The Directors are of the opinion that the Company meets the typical characteristics of an investment entity and will reassess this conclusion on an annual basis.

Assessment of the Midco as an investment entity

The Midco (see note 9) is not consolidated as it is considered to be an investment entity. The Board of the Midco have considered the requirements of IFRS 10 as per above and confirm the Midco meets these criteria. If the Midco was not considered to meet the definition of an investment entity, then the Company would be required to consolidate the entity. The impact of consolidating the Midco would be to increase the investment value to £577,228,493 (31 December 2021: £401,115,427) and net working capital would decrease by £12,513,504 (31 December 2021: £11,768,679).

Investment Manager not a related party

The AIFM is not disclosed as key management personnel in the financial statements. To meet the key management personnel definition the AIFM would need to have authority and responsibility for planning, directing and controlling the activities of the entity. The Directors are of the opinion that the AIFM does not meet these criteria as the Board has to approve key decisions

Valuation of investments in subsidiaries

Significant estimates in the Company's Condensed Financial Statements include the amounts recorded for the fair value of the instruments. By their nature, these estimates and assumptions are subject to measurement uncertainty and the effect on the Company's Condensed Financial Statements of changes in estimates in future periods could be significant. See note 15 for further details.

 

4.   Fees and expenses

Accounting, secretarial and directors

JTC (UK) Limited acts as secretary and administrator for the Company through the Administration and Company Secretarial Agreement. JTC (UK) Limited is entitled to a £60,000 annual fee for the provision of Company Secretarial services and a £55,000 annual fee for the provision of fund accounting and administration services, based on a Company Net Asset Value of up to £200mn. An ad valorem fee based on total assets of the Company which exceed £200mn will be applied as follows:

§ 0.04% on the Net Asset Value of the Company in excess of £200mn

During the period, expenses incurred with JTC (UK) Limited for administrative and secretarial services amounted to £143,194 (2021: £88,312) with £35,784 (2021: £29,210) being outstanding and payable at the period end.

AIFM

The AIFM, Gresham House Asset Management Limited (the Investment Manager), is entitled to receive from the Company, in respect of its services provided under the AIFM agreement, a fee as follows:

§ 1% on the first £250mn of the Net Asset Value of the Company

§ 0.9% on the Net Asset Value of the Company in excess of £250mn and up to and including £500mn

§ 0.8% on the Net Asset Value of the Company in excess of £500mn

During the period, Investment Manager fees recognised in these Condensed Financial Statements amounted to £2,633,215 (2021: £1,754,677) with £1,438,960 (2021: £896,591) being outstanding and payable at the period end.

7.   Taxation

The Company is recognised as an Investment Trust Company (ITC) for the accounting period and is taxed at the main rate of 19%.

The Company may utilise group relief or make interest distributions to reduce taxable profits for the period to 30 June 2022, therefore, no corporation tax charge has been recognised for the Company for the period.

8.   Earnings per Ordinary Share

Earnings per Ordinary Share (EPS) amounts are calculated by dividing the profit or loss for the period attributable to ordinary equity holders of the Company by the weighted average number of Ordinary Shares in issue during the period. As there are no dilutive instruments outstanding, basic and diluted Earnings per Ordinary Share are identical.

		Revenue  (£)		Capital  (£)	Total (£)
Net profit attributable to ordinary shareholders		10,316,041		131,571,872	141,887,913

Profit per Ordinary Share (basic and diluted) - pence per Ordinary Share		2.47	7.95	10.42

 

9.   Investment in subsidiaries

The Company meets the definition of an investment entity. Therefore, it does not consolidate its subsidiaries but, rather, recognises them as investments at fair value through profit or loss. The Company is not contractually obligated to provide financial support to the subsidiaries and there are no restrictions in place in passing monies up the structure.

The Directors evaluate the performance of the portfolio of energy storage investments through its subsidiary companies on a fair value basis. The income approach is used to value investments as it indicates value based on the sum of the economic income that a project, or group of projects, is anticipated to earn in the future. Where projects are acquired within the quarter to the valuation date, the cost approach is used to determine the fair value.

Therefore, the investments in subsidiaries are measured at FVTPL under IFRS 9, as these financial assets are managed and their performance evaluated on a fair value basis.

15. Fair value measurement

Valuation approach and methodology 

The same valuation methodology and process is followed in these Condensed Financial Statements as was applied in the preparation of the Company's Annual Financial Statements for the year ended 31 December 2021. The Company used the income approach to value its investments.  The income approach indicates value based on the sum of the economic income that an asset, or group of assets, is anticipated to produce in the future. Therefore, the income approach is typically applied to an asset that is expected to generate future economic income, such as a business that is considered a going concern. Free cash flow to total invested capital is typically the appropriate measure of economic income. The income approach is the DCF approach and the method discounts free cash flows using an estimated discount rate (WACC).

Valuation process 

The Company, via the Midco, held a portfolio of energy storage investments with a capacity of 425 Megawatt ("MW") operational (the Investments). The Investments comprise 28 projects held in 24 special project vehicles.

  

All of these investments are based in the UK. The current portfolio consists of non-market traded investments, and valuations are analysed using forecasted cash flows of the assets and use the discounted cash flow approach for valuation purposes.  The Company engages external, independent, and qualified valuers to determine the fair value of the Company's investments or valuations are produced by the Investment Manager.  As at 30 June 2022 the fair value of the portfolio of investments has been determined by the Investment Manager and reviewed by Grant Thornton UK LLP.

 

The valuations have been determined using discounted cash flow methodology, whereby the estimated post-tax future cash flows relating to the Company's equity investment in each project have been discounted to 30 June 2022, using post-tax discount rates reflecting the risks associated with each investment project and the time value of money. The Investment Manager believes that use of post-tax discount rates is most appropriate methodology to determine fair values.

New operational projects acquired are initially held at cost, which is deemed to be fair value, and are revalued once the performance of the assets has been verified. The valuation of these assets, after the initial period, is performed on the same basis as the remainder of the portfolio. Assets in the course of construction are also held initially at cost, but are revalued, with a construction risk premium of 0.5%, once certain criteria are met including the timescale to expected commercial operations and the signing of certain contracts.

The determination of the discount rate applicable to each individual investment project takes into account various factors, including, but not limited to, the stage reached by each project, the period of operation, the historical track record, the terms of the project agreements and the market conditions in which the project operates.

The Investment Manager exercises its judgement in assessing the expected future cash flows from each investment. The Investment Manager produces detailed financial models for each underlying project. The Investment Manager makes amendments where appropriate to: 

a)   discount rates (i) implied in the price at which comparable transactions have been announced or completed in the UK energy storage sector (if available); (ii) publicly disclosed by the Company's peers in the UK energy storage sector (if available); and (iii) discount rates applicable for other comparable infrastructure asset classes and regulated energy sectors; 

b)   changes in power market forecasts from leading market forecasters; 

c)   changes in the economic, legal, taxation or regulatory environment, including changes in retail 
price index expectations; 

d)   technical performance based on evidence derived from project performance to date; 

e)   the terms of any power purchase agreement arrangements; 

f)    accounting policies; 

g)   the terms of any debt financing at project level; 

h)  claims or other disputes or contractual uncertainties; and 

i)    changes to revenue, cost or other key assumptions (may include an assessment of future 

cost trends, as appropriate). 

 

Valuation assumptions include consideration of climate related matters such as expected levels of renewable energy entering the grid system, demand patterns and current regulatory policy. These are factored into the pricing assumptions which are prepared by an independent consultancy.

The Board reviews the operating and financial assumptions, including the discount rates, used in the valuation of the Company's underlying portfolio.

		30 June 2022			31 December 2021
Key valuation input		Range (project) average		Weighted average	Range (project) average	Weighted average
WACC / WADR		9.99% - 11.35%		10.79%	9.99% -11.40%	10.77%
RPI (see assumption below)		2.7%-2.8%	2.7%		2.8%-2.9%	2.8%

 

RPI assumptions include 7.5% for 2022, 4.5% for 2023 and 2.5% from 2025.

 

Another key assumption in the valuation models is the volatility of power prices. Due to the Asset Optimisation strategy, the investments are able to benefit from a range of revenue streams, either arbitrage on power price volatility or FFR and other similar income streams. Due to the nature of the assets owned by the investments, should one revenue stream be impacted the asset is able to switch to alternative sources of revenue to seek to maintain total revenue targets.

 

Sensitivity analysis

The below table reflects the range of sensitivities in respect of the fair value movements of the Company's investments, via the MidCo.

 

The sensitivity analysis does not include an assessment of the fall in the power price as underlying power information is provided on a net revenue basis as the investment portfolio generates value through maximising on the volatility in the market, therefore adjusting revenue as a total is a more relevant measure. Therefore, we have provided a sensitivity based on percentage changes in revenue overall.

The level in the fair value hierarchy within which the fair value measurement is categorised is determined on the basis of the lowest level input that is significant to the fair value measurement in its entirety.  For this purpose, significance of the inputs is assessed against the fair value measurement in its entirety.  Assessing the significance of a particular input to the fair value measurement in its entirety requires judgement, considering factors specific to the asset or liability.  If a fair value measurement uses observable inputs that require significant adjustment based on unobservable inputs or any other significant unobservable inputs, that measurement is a Level 3 measurement.

 

Valuation of financial instruments

The investment at fair value through profit or loss is a Level 3 in the fair-value hierarchy and the reconciliation in the movement of this Level 3 investment is presented below. No transfers between levels took place during the period.

 

16. Financial risk management

As at 30 June 2022 there have been no changes to the financial instruments risk identified in the Annual Financial Statements of 31 December 2021.

The Company is exposed to certain risks through the ordinary course of business and the Company's financial risk management objective is to minimise the effect of these risks. The management of risks is performed by the Directors of the Company and the exposure to each financial risk considered potentially material to the Company, how it arises and the policy for managing it is summarised in the Annual Financial Statements of 31 December 2021.

The Company's only financial liabilities are trade and other payables. The Company has sufficient cash reserves to cover these in the short to medium term. The Company's cash flow forecasts are monitored regularly to ensure the Company is able to meet its obligations when they fall due.

The following table reflects the maturity analysis of financial assets and liabilities.

Asset optimisation

Asset optimisation involves buying and selling electricity in order to capture a spread between the high and low electricity prices on any given day. This can be done via one or more market mechanisms, hence the expression ''Asset Optimisation''.

An asymmetrical grid connection is where the import and export capacities are different.

Balancing Services

National Grid procure services to balance demand and supply and to ensure the security and quality of electricity supply across Britain's transmission system.  These include:

§ Black Start

§ Demand side response

§ Enhanced frequency response (EFR)

§ Firm frequency response (FFR)

§ Short term operating reserve (STOR)

C-rate

A unit to measure the speed at which a battery is charged or discharged.1C reflects a charge of 0% to 100% (or discharge of 100% to 0%) in one hour, a C-rate greater than 1 means a faster charge (or discharge) and less than 1 means a slower charge (or discharge). The C-rate can be calculated as 1 divided by the time it would take for the charge (or discharge) in hours. Therefore, 2C is a half hour charge (or discharge), and 0.5C is a 2-hour charge (or discharge). A BESS max C-rate is calculated as 1 divided by the Battery duration in hours.

Capacity Market

The income received by generators to ensure generation capacity is available to meet shortfalls.

Curtailment

Large wind farms are connected to the UK's high-voltage network and National Grid balances electricity supply and demand.  As demand rises and falls during the day, electricity supply mirrors these peaks and troughs.

National Grid accepts bids and offers from electricity generators to increase or decrease electricity generation as and when required. As such it may mean that there are times when generators are paid to curtail their output (constraint payments).

Dynamic Frequency Services:

 

Consists of three services Dynamic Containment (DC), Dynamic Moderation (DM) and Dynamic Regulation (DR). Each of these services focuses on a different frequency deviation however all have a response power linked to a frequency deviation profile.

Dynamic Regulation is a pre-fault service designed to slowly correct continuous but small deviations in frequency with the aim of regulating frequency around 50Hz. Dynamic Moderation is designed to help manage sudden large imbalances between supply and demand to ensure frequency is maintained within operational limits. Dynamic Containment acts post-fault and is designed to quickly cover lost supply or demand and to help return frequency to within operational limits as quickly as possible.

EPCm

Contracts for Engineering, Construction and Procurement Management.

 

NAV

Net Asset Value being the total Net Assets in the Company divided by the total number of Ordinary Shares in issue as at 30 June 2022.

Ongoing Charges Figure (OCF)

The Ongoing Charges Figure includes all charges and costs incurred by the Company which relate to the ongoing operation of the Company. This includes management fees, administration fees, audit fees, Director's remuneration, depositary services costs and other similar costs. It excludes capital costs and costs of raising new capital. The Ongoing Charges are then divided by the weighted average NAV and annualised.

Ordinary Share

Share in the Company with a nominal value of 1 penny.

Symmetrical

A symmetrical grid connection is where the import and export capacities are the same.

TRIADs

Triads are defined as the three half-hours of highest demand on the GB electricity transmission system between November and February each year, the Triads are part of a charge-setting process. This identifies peak electricity demand at three points during the winter in order to minimise energy consumption. However, Triads must be at least 10 days apart. This is to avoid all three potentially falling in consecutive hours on the same day, for example during a particularly cold spell of weather.
