Control technology firm Encorp will deploy a new fleet of six microgrids for critical services within the county of Alameda in northern California.
Alameda County government is planning for on-site solar, battery storage, generators and equipment resources to power microgrids supporting its Contract Services Building, the San Lorenzo Library, Social Services, Turner Court Building, Peralta Oaks-Sheriff’s Office and the Santa Rita Jail ROTC Complex (pictured above).
“These projects will deliver substantial environmental benefits by lowering fuel energy costs, reducing greenhouse gas emissions and diminishing our dependence on fossil fuels,” Tom Wesig, energy program manager for Alameda County, said in a statement. “Beyond environmental impact, they will also drive job creation and bolster energy resilience.
Colorado-based Encorp will provide its Egility microgrid control platform and will also serve as engineering, procurement and construction (EPC) lead for all six microgrid projects. The company typically focuses on the technology and software side of the microgrids but has served as EPC contractor for the $1.5 million microgrid for Red Feather Lakes in Colorado and the $5 million Kings River Packing’s Cobblestone facility in central California.
Cost of the Alameda County project is valued at $45.3 million and includes financing and incentives from the federal Inflation Reduction Act of 2022. Four of the six microgrids will be located within low-income zones, Encorp CEO Michael Clark said.

Encorp’s original microgrid work at Santa Rita Jail dates back to 2021. In the past year alone, the company also has contributed microgrid control technologies for projects in Georgia, Bahamas and Scotland, among others.
Pacific Gas & Electric, which is the primary utility for northern California, has interconnected numerous microgrids within its distribution system and also recently announced work on six new remote microgrids for communities.
