Ecotricity has signed an agreement to provide renewable energy from a fresh source - deep under Cornwall.

Stroud-based Ecotricity, the world's first green energy company, has partnered with Geothermal Engineering Limited to provide geothermal electricity for the first time in the UK.

The site at United Downs near Redruth will generate steam from three miles under the ground.

Ecotricity founder Dale Vince said: "Geothermal is a really exciting form of energy that is untapped in the UK.

"We're pleased to be part of this project and to add the power to our customer's energy mix.

"It has a big role to play in our plans to decarbonise the country."

Ecotricity has agreed a 10-year power purchase agreement for energy generated at the site which will produce a minimum of three megawatts - enough to power 10,000 homes a year via the National Grid.

The plant is expected to be fully operational early next year.

Geothermal Engineering founder Dr Ryan Law said: "We have spent many years working towards this point and are thrilled to see this pioneering geothermal power plant coming together.

"Our work shows the significant potential of geothermal energy to supply both heat and energy across Cornwall.

"We are very excited for the industry, investment and jobs this renewable resource could bring to the region."
