Pioneer Diversifies Its Energy Portfolio Adding Northern California Geothermal

Pioneer Community Energy (Pioneer) added geothermal electricity produced in Northern California from The Geysers to its renewable energy portfolio through a 10-year agreement with Calpine Energy Services, LP (Calpine).

Pioneer’s contract with Calpine runs from 2022 to 2031 and will provide Pioneer with 8 megawatts of renewable energy. The geothermal plants at The Geysers generate electricity 24 hours a day, seven days a week making them an attractive complement to Pioneer’s renewable portfolio. The Calpine contract will also contribute to Pioneer’s long-term Renewables Portfolio Standard requirements as prescribed by the California Public Utilities Commission (CPUC).

The Geysers, consisting of 13 geothermal plants with 725 megawatts of capacity, is the world’s largest geothermal resource developed for electric generation. Located in the Mayacamas Mountains in Lake and Sonoma Counties, the plants harness naturally-occurring hot steam fields below the earth’s surface to make clean, renewable energy.
