Batteries helped (mostly) as California’s grid endured record demand

As a power crunch precipitated by an extended heat wave eased, the California Solar and Storage Association (CALSSA) said that the state had more than 80,000 customer-sited batteries connected to the electric grid capable of providing 900 MW of solar power. It said that while not all the batteries were set to discharge during the peak hours of 4pm-9pm on September 6, an estimated 76% were, capable of providing up to 684 MW of power at any given moment. The trade group said that 50% of these batteries’ aggregate power was put into use during peak hours. - Renewable Energy World
