Energy Storage News:

Augmentation at the Vistra Moss Landing Energy Storage Facility in California has been completed, with the world’s biggest battery energy storage system (BESS) now at 400MW / 1,600MWh. 

Retail and power generation company Vistra Energy brought the 300MW / 1,200MWh Phase 1 of the BESS project online in December 2020 at a site formerly occupied by natural gas turbines at its Moss Landing Power Plant in California’s Monterey County. 

Vistra and lithium-ion battery rack supplier to the project LG Energy Solution held a media day yesterday to celebrate the successful completion in July of Phase 2. Along with the two companies and their engineering, procurement and construction (EPC) partner Burns & McDonnell, the event was attended by representatives from California grid and electricity market operator CAISO, utility Pacific Gas & Electric (PG&E), federal and local authorities and business leaders. 

“This facility provides a solution California desperately needs and this expansion was able to come online at the right time – as the summer heat intensifies and demand for electricity is at its highest,” Vistra CEO Curt Morgan said.

“The state’s laudable immense buildout of intermittent renewable power has both lowered emissions and presented a reliability challenge. California produces an excess amount of renewable power during the day while the sun is up, but often struggles to meet demand as the sun goes down. Our Moss Landing battery system helps to fill that reliability gap, storing the excess daytime power so it doesn’t go to waste and then releasing it to the grid when it’s needed most.”
