Centrica and Ceres sign strategic partnership to bring multi‑GW

on‑site fuel cell power to the UK and Europe

Horsham, UK:  Ceres Power Holdings plc ("Ceres"), a UK‑based clean energy technology leader, today announces a collaboration with Centrica plc ("Centrica") to accelerate the deployment of solid oxide on‑site power solutions to meet the multi-gigawatt demand from commercial and industrial customers across the UK and Europe.

With electricity grid connection delays impacting new industrial, commercial and digital projects, the UK and Europe are experiencing a widening gap between demand and available capacity. Through this collaboration, Centrica will be able to offer customers high‑efficiency, low‑carbon, grid independent on‑site power that can be deployed much faster than gas turbines or nuclear.

By bringing together Centrica's market‑leading energy supply, trading and services platform with Ceres' advanced Solid Oxide Fuel Cell (SOFC) and Solid Oxide Electrolysis Cell (SOEC) technologies, the partnership enables fast, scalable deployment of high‑efficiency, fuel‑flexible on‑site generation for data centres, AI compute hubs, advanced manufacturing, logistics and distribution centres, as well as other critical commercial and industrial applications. Ceres' SOFC technology delivers high electrical efficiency, quiet operation and fuel flexibility, operating on natural gas today whilst providing a clear pathway to other fuels such as biogas and hydrogen in the future. The technology is also inherently suited to carbon capture applications.

Initially, Ceres will support Centrica in expanding a new differentiated service-led model for clean power, providing access to British technology at scale and pace through its expanding ecosystem of global manufacturing partners. Ceres will assist Centrica with opportunities across project origination, installation and commissioning, remote monitoring, predictive maintenance and end of life recycling ensuring customers benefit from a full lifecycle solution. In addition, Centrica is also exploring how Ceres' high‑efficiency SOEC technology could integrate with its AMR programme to produce nuclear‑enabled green hydrogen, strengthening the UK's long‑term clean energy strategy.

Centrica's gas and power trading capabilities will underpin a powerful customer proposition that integrates technology and fuel supply, structured energy contracts, long-term cost certainty and optimisation of on‑site generation into flexibility and balancing markets.

Chris O'Shea, Chief Executive of Centrica plc said: "Businesses across the UK and Europe need more power, and they need it faster than the electricity grids can deliver. This partnership is about offering customers a reliable, efficient source of on‑site power that can be up and running quickly. By combining Ceres' technology with our energy expertise, we see a real opportunity to support data centres, AI and industry with cleaner power at scale, while helping to ease pressure on the grid and boost economic growth."

Phil Caldwell, CEO of Ceres said: "This partnership is a powerful realisation of British technology applied at global scale. Leveraging Centrica's energy capabilities and Ceres global network of world‑class manufacturing partners, we can deliver low‑carbon, high‑efficiency power solutions for the fast‑growing data centre and on‑site power sector in the UK and Europe."
