OFGEM ANNOUNCEMENT ON EAST ANGLIA ONE OFTO INVESTMENT

2 November 2022

International Public Partnerships Limited ('INPP' or 'the Company'), the listed infrastructure investment company, notes that Ofgem, as anticipated, published a notice under Section 8A of the Electricity Act 1989 on 1 November 2022 relating to the East Anglia One Offshore Transmission project ('OFTO')[1]. This is a key step towards reaching financial close on the investment that the Company expects to make in the project. The Company expects to invest c.£105 million into the project upon financial close, anticipated to be in December 2022.

The project will be the Company's tenth OFTO investment and relates to the transmission cable connection to the offshore wind farm located c.50km off the coast of Suffolk. The wind farm consists of 102 x 7MW wind turbine generators with an installed capacity of 714MW connected to the offshore substation platforms ('OSP') located within the boundaries of theEast Anglia One wind farm.

This investment will further increase the Company's contribution to the UK's transition to a net zero carbon economy. The East Anglia One OFTO has the capacity to transmit enough renewable electricity to power the equivalent of over 600k homes, increasing the total equivalent across the Company's OFTO portfolio to c.2.7 million homes.

The Company takes no exposure to electricity production or price risk but is paid a pre-agreed, availability-based revenue stream over 21.5 years which is linked to UK inflation (as measured by the Retail Price Index).

As previously announced, the Company is also preferred bidder on Moray East OFTO.

ENDS.
