The United Downs Deep Geothermal Power project is the first development of its kind in the UK. It is located near Redruth in west Cornwall and is part-funded by the European Regional Development Fund and Cornwall Council. Two wells have been drilled to intersect a target fault structure that, it is hoped, will provide enough natural permeability to allow circulation between the wells and the generation of between 1 and 3MWe.

Drilling began in November 2018 and was completed at the end of June 2019. The production well reached a depth of 5,275m (MD) and the injection well 2,393m (MD), and the project is now in its evaluation phase.

Peter will outline the geothermal resources in Cornwall, describe the development of the UDDGP project and give an update on progress.
