Calpine, a business unit of Constellation, has announced the completion of a 25-MW expansion project at The Geysers geothermal complex located in Sonoma County, California. The addition builds on Calpine's continued investments in The Geysers to support California's renewable energy goals and follows the completion of a 38 MW energy storage system at the site in 2024. The new capacity will generate enough electricity to power over 25,000 homes each year.
