The John L. Featherstone Plant is a world-class geothermal power generating facility located in the Imperial Valley of Southern California, within the Salton Sea Known Geothermal Resource Area (“KGRA”).  The Facility employs a "triple flash" technology, similar to other plants in the Salton Sea KGRA and in other very robust geothermal resource areas.  Hot, pressurized geothermal brine is brought to the surface from the production wells and energy is extracted by allowing the brine to cool slightly by releasing energy in the form of steam (“flashing”) by sequencing three controlled pressure reduction operations.  The resulting steam is then processed and sent to the turbine generator and the remaining brine is further processed to remove mineral solids prior to reinjection.
