The theoretical potential for 'identified resources' represents the estimated proportion of the geothermal resource that is available for development. The maps are provided in raster format at a 100 m resolution.  For consistency with other legacy estimations, additional columns have been added to the original layers to include the converted value of 'identified resource' to 'recoverable heat' in MW/km2, for equivalence to the method used by D J.R.

(1995). Rollin, K. E., G. A. Kirby, and W. J. Rowley. Atlas of geothermal resources in Europe: UK revision. British Geological Survey technical report WK/95/7, Regional Geophysics Group, 1995: https://webapps.bgs.ac.uk/data/publications/publication.html?id=21735106. The 'identified resources' are defined as a function of the 'heat-in-place', the hydraulic properties of the aquifer, the method of abstraction or recovery factor (F = 0.33) and the reject temperature of the disposal fluid (Tj = 25 °C). As part of the 2025 UK Geothermal Platform project, the maps for each basin were merged into a single layer. For consistency with other legacy estimations, the theoretical potential 'recoverable heat' (MW/km2) was calculated from the 'identified resources' layer using a conversion factor of 0.287, accounting for a recovery factor of 0.1, a plant factor of 0.95, a conversion efficiency factor of 0.85 and a plant operational lifetime of 30 years, for equivalence to the 3DHIP method used in the more recent BGS geothermal resource assessment studies (Jones et al., 2023; Kearsey et al., 2024).
