The naturally heated water, exceeding 190°C, generates electricity 24 hours a day, 7 days a week regardless of the weather.
From the article:
The UK’s first geothermal power plant has just begun operations, using hot water from deep underground to create renewable electricity. The United Downs plant in Cornwall has been in development for nearly two decades, and will now begin providing enough electricity to power 10,000 homes. Geothermal power generation comes via energy stored in the form of heat beneath the surface of the Earth. The company behind the project, (GEL) Geothermal Engineering Ltd., had to drill the deepest on-shore well ever drilled on UK soil—over 3 miles deep—to source the geothermal fluid that is used for the power plant. The naturally heated water, exceeding 190°C, generates electricity 24 hours a day, 7 days a week regardless of the weather. The water will help drive turbines to generate electricity for 10,000 homes but will also provide the UK’s first domestic supply of lithium, a critical mineral used in green technology.
