MCE & Calpine add 7 MW of new geothermal power through the North Geysers Incremental Development project—delivering reliable, renewable energy to MCE’s customers across Contra Costa, Marin, Napa & Solano Counties.
Calpine proudly supports the communities we serve beyond the power we provide.
In 2025, Calpine contributed $50,000 in community donations to Boys & Girls Club of Middletown Rancheria of Pomo Indians, Friends of Boggs Mountain and Luther Burbank Center’s Mariachi Summer Camp. These donations support youth extracurricular activities and wildland restoration efforts.
Through the 25 MW North Geysers Incremental Development expansion project, Calpine will distribute an additional $50,000 in community donations this year.
