Bear Canyon Battery Storage

Having reached commercial operations in Q3 2024, Bear Canyon Energy Storage (“BCES”) is a 13-megawatt (MW) battery energy storage system (“BESS”) on the repurposed Bear Canyon geothermal facility site at The Geysers. BCES uses lithium-ion battery technology to store electricity (charge mode) at times of excess generation and/or low demand and then delivers electricity (discharge mode) back to the grid for use in periods of high demand. The BESS has a 4-hour discharge capability resulting in the ability to discharge a total of 52 megawatt-hours (MWh). 

In addition, BCES has the ability to provide other services such as regulating voltage for protection of the grid.
