Octopus Energy has committed to purchasing at least 3 megawatts of Geothermal Engineering Limited's (GEL) constant geothermal output from its United Downs facility, enough to provide clean energy for approximately 10,000 U.K. homes.

Deal Analysis

Octopus Energy's commitment to purchase 3 MW of constant geothermal output from Geothermal Engineering Limited (GEL) via a Power Purchase Agreement (PPA) represents a significant development for the United Kingdom's emerging geothermal sector. This announced PPA, originating from GEL's United Downs facility, is projected to supply clean energy for approximately 10,000 U.K. homes, underscoring a tangible move towards diversifying the nation's renewable energy mix with a baseload power source. This deal is notable for several reasons. It marks one of the earlier commercial PPAs for geothermal energy in the United Kingdom, a market where this technology is still in its developmental stages. The involvement of Octopus Energy, a prominent energy supplier with a focus on renewables, as the offtaker provides crucial long-term revenue certainty for GEL, an independent power producer pioneering geothermal development. While the financial value remains undisclosed, the 3 MW capacity is a foundational step for the United Downs project and signals growing confidence in geothermal's potential to contribute to the UK's energy transition landscape.
