Ideally new sites would be located on brownfield or industrial land. However, the reality in Cornwall is that there are very few brownfield sites, and almost none that are large enough for a drilling rig and within reach of a suitable fault structure for geothermal fluid flow.

A list of brownfield sites can be found on the Council Register of Brownfield Land or shown on the Cornwall Interactive Map. During geothermal site selection, GEL must weigh up a huge number of factors and where a  brownfield site isn’t available, GEL will do its best to limit proximity to conservation areas and densely populated locations.
