Durham’s FlexGen to Supply 420MWh of Energy Storage System in California

Durham-based battery energy storage solution and software technology provider FlexGen Power Systems has been selected to supply energy storage technology and software for 420MW of energy storage across four California sites to Middle River Power. The energy storage projects are collocated with existing simple cycle natural gas peaking plants, and the facilities will share interconnection facilities.

Middle River Power operates, manages and develops over 3,000 MW of power.

FlexGen said that collocating the natural gas peaking facilities with battery storage results in significant reductions in greenhouse gas emissions while maintaining reliable, flexible reserve capacity.  The battery facilities will be used to store excess carbon-free power during the day and release it when it is most needed over the evening hours.  Also, gas turbines will dispatch less often than they do usually, resulting in lower emissions, while remaining available to dispatch during extreme conditions.

Kelcy Pegler, CEO, FlexGen said, “Energy storage is critical to the future of the grid, and FlexGen has spent the last decade honing our capabilities to deliver critical energy storage assets to our partners.”

“The energy storage assets store plentiful solar energy in the middle of the day then deploy that energy to the grid during evening peak hours, while maintaining our natural gas facilities as a flexible, reliable backstop” said Mark Kubow, President of Middle River Power. “We are excited to introduce our first tranche of projects that takes such a meaningful step in helping California in the transition to more renewable resources.”

FlexGen offers integration services and software technology for ESS in the US and global market. Its clients and partners include developers, utilities, government agencies and industrial companies.
