Calpine is completing a 25 MW expansion project at The Geysers. The North Geysers Incremental Development (“NGID”) will help meet mid-term reliability needs for the California electricity system.
Currently, with 13 power plants in operation at The Geysers, Calpine Corporation reliably supports California with up to 725 megawatts of clean, geothermal energy every hour of every day. The NGID project expands Calpine’s operations by drilling eleven new production and two new injection wells within the Northern portion of The Geysers resource. Utilizing existing steam field infrastructure, the wells will be drilled on four well pads with piping to transfer the superheated steam to nearby operating geothermal power plants to increase overall output.
NGID is a multi-year project that Calpine will bring on-line in phases, anticipated to be fully completed by June 2026. In operation for nearly 65 years, geothermal from The Geysers is a proven consistent source of renewable energy and the NGID project is the next step in Calpine’s sustainable management approach of the resource while adding to the many community and environmental benefits to local region.
