United Downs Deep Geothermal Power is the United Kingdom's first geothermal electricity project. It is situated near Redruth in Cornwall , England. It is owned and operated by Geothermal Engineering (GEL), a private UK company. The drilling site is on the United Downs industrial estate, chosen for its geology, existing grid connection, proximity to access roads and limited impact on local communities. Energy is extracted by cycling water through a naturally hot reservoir and using the heated water to drive a turbine to produce electricity and for direct heating. The company plans to begin delivering electricity (2 MWe) and heat (<10 MWth) in 2024. A lithium resource was discovered in the well.
53-403: The Camborne School of Mines led Cornish Hot Dry Rocks (HDR) project, undertaken in the 1980s at Rosemanowes Quarry , was designed to test the theory of inducing a fracture network within granite to create a geothermal reservoir.

1484-429: The UK has been limited, partly due to the lack of high enthalpy resources, but also due to the availability of cheap fossil fuels. However, when comparisons are made to countries in a similar tectonic setting, it is clear that the UK is underutilising this potential resource. The lack of geothermal development has largely been a result of the availability of North Sea natural gas during the 1980s and 1990s. Interest in
1537-657: The UK is 26 °C, 47 °F per kilometre (42 °C, 76 °F per mile) depth. There is no deep geothermal power generation in the UK. The granite regions of South West England, the Lake District and Weardale and the Eastern Highlands of Scotland are considered most likely to have the best prospects for power generation. In addition to using geothermally heated aquifers, Hot-Dry-Rock geothermal technology can be used to heat water pumped below ground onto geothermally heated rock. Starting in 1977, trials of

This temperature difference is exploited by ground source heat pumps that are used for heating and/or cooling of homes and office buildings. Groundwater in Permo-Triassic sandstones in the UK has the potential to provide an exploitable geothermal resource at depths of between 1 and 3 km (0.62 and 1.86 miles). Since 1979

1802-513: The company failed to secure the necessary additional investment to meet the terms of the grant. By 2016, the company had managed to secure £30 million funding for the project from a combination of the European Regional Development Fund , Cornwall Council and private investors, thus financing the UK's first commercial hot rocks power scheme. In 2019, the company had finished drilling the two geothermal wells;
1855-568: The company received another £15 million in private funding. The geothermal system employed to generate power at United Downs targeted a radiogenic granite batholith that exhibited enhanced permeability due to its intersection with the Porthtowan fault zone . The Cornubian granite batholith stretches from Dartmoor to the Isles of Scilly and contains a high concentration of heat-producing isotopes such as thorium (Th), uranium (U) and potassium (K). This natural heat production means that
