OFGEM ANNOUNCEMENT ON RAMPION OFTO INVESTMENT

29 September 2021

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 28 September 2021 relating to the Rampion 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. As previously reported, the Company expects to invest c.£40 million into the project upon financial close, anticipated to be in November 2021.

The project will be the Company's ninth OFTO investment and relates to the transmission cable connection to the offshore wind farm located 13km off the Sussex coast. The wind farm consists of 116 x 3.45MW wind turbine generators with an installed capacity of 400MW connected to the offshore substation platforms ('OSP') located within the boundaries of the Rampion wind farm.

This investment will further increase the Company's contribution to the UK's transition to a zero-carbon economy. The Rampion OFTO will transmit green electricity equivalent to around 350,000 UK homes, increasing the number of homes that are powered by the Company's OFTO portfolio to approximately 2.1 million homes.

The Company takes no exposure to electricity production or price risk but is paid a pre-agreed, availability-based revenue stream over 20 years which is fully linked to UK inflation ('RPI').

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

ENDS.
