Convergent Energy + Power wins 35 MW energy storage contract

Convergent Energy + Power, an energy storage asset developer, is contracted to deliver a 35 MW, 140 MWh energy storage system to provide targeted electric capacity and other benefits to the California grid.

The project was approved by Southern California Edison as part of SCE‘s competitive Preferred Resources Pilot solicitation, a program designed to meet local demand through clean energy resources. SCE recognizes the ability of energy storage to address multiple grid constraints and challenges in cleaner, more responsive and cost-effective ways.

“Energy storage can provide location-targeted capacity that relieves electric system constraints and meets reliability standards, while also increasing grid flexibility and resiliency,” said Christopher Streeter, Convergent’s CIO. “Our team is looking forward to working with SCE to support California’s broader transition to a more advanced, low-emission, cost-efficient electric grid.”

As a technology-neutral energy storage developer, Convergent offers a wide array of technology options for utilities, grid operators and project developers. The company’s projects include a 3 MWh, 6-hour continuous discharge battery used for transmission and distribution system upgrade deferral in Central Maine Power service territory; a next-generation 10 MW, 4-hour hybrid-zinc battery for Pacific Gas & Electric; as well as a 5 MW, 6-minute flywheel and 7 MW, 1-hour battery used for frequency regulation and voltage support services by the Ontario Independent Electricity System Operator.

Convergent successfully proposed to provide four hours of continuous discharge capability for peak shaving and grid balancing services in southern Orange County, an area with significant load growth that was also impacted by the recent retirement of the San Onofre nuclear plant. Beyond their reliability benefits, these new energy storage projects will also bring economic value to California’s wholesale electricity marketplace.
