Peru’s Ministry of Energy and Mines has authorised Hot Rock Peru Limited to proceed with the second phase of its exploration of geothermal resources in the country.

The ministry’s director of electricity, Roberto Tamayo, confirmed work will start in May 2014 in the regions of Ancash, Moquegua, Puno and Arequipa, El Comercio reports.

To reach the extraction phase and the generation of 100 MW, it is estimated that Hot Rock will require an investment of approximately $250m.

Officials from the Geothermal Association of Peru told Andina that South America’s most-promising geothermal resources lay in Peru – an estimated potential of 3000 MW with 2200 MW in the south of the country.
