Canadian Solar’s project development subsidiary Recurrent Energy has signed a 15-year deal with California utility Pacific Gas & Electric (PG&E) for energy capacity from one of the world’s biggest battery energy storage system (BESS) projects.
Financing has been secured for two projects that will add nearly a gigawatt-hour of battery storage at California solar power facilities this year, by renewable energy company Terra-Gen and private asset management firm Capital Dynamics.
Commissioned at the start of this year, the Alamitos Battery Energy Storage System in California is a landmark project for the industry in having competed against natural gas to provide peaking capacity for the grid. Andy Colthorpe finds out the project’s backstory.
A company that pairs available energy capacity with the needs of electric utilities is preparing to put 288MW of flexible power onto the California grid in time for the summer peak in electricity demand that threatens energy security across the state each year.
Canadian Solar has been on a “transformational journey to accelerate demand” for its battery energy storage services, CEO Dr Shawn Qu said while discussing what has been a quarter beset with difficulties for the company’s solar manufacturing business.
A rapid and significant increase in battery storage capacity will be among factors contributing to an improved energy security position for California’s electricity networks this summer, but the grid is still vulnerable to stress during any extreme heatwaves.
