Electrochemical and other energy storage technologies have grown rapidly in China. Global wind and solar power are projected to account for 72% of renewable energy generation by 2050, nearly doubling their 2020 share. However, renewable energy sources, such as wind and solar, are liable to intermittency and instability.
At 300MW / 1,200MWh, the BESS is considerably larger than the 250MW / 250MWh Gateway Energy Storage project brought online earlier this year by LS Power, also in California.Not only that, but Phase 2 of Vistra''s
