San Diego Gas & Electric (SDG&E) has announced it will double its battery backup capacity in an effort to support its service area’s renewable energy growth.
SDG&E President Scott Drury announced the initiative this week, saying the electric company is at the “forefront” of the industry in terms of energy storage, according to timesofsandiego.com.
The article states that the utility plans to build five more lithium-ion battery backup facilities — including one of the biggest in the United States — over the next three years. The new plants in Escondido, Fallbrook, Miramar, Poway and San Juan Capistrano will add nearly 100 megawatts of capacity
Currently, SDG&E generates 44% of its power from solar and wind but Drury and his team feel even more battery storage capacity is necessary, as it enables the utility to store or release power as needed.
San Diego has long been a proponent of renewable energy. In May 2017, the city and the San Diego County Water Authority are developing a way to store energy by using water. Water officials said it’s expected to save ratepayers money in the long run. The city announced a goal to build an energy storage facility at the San Vicente Reservoir, 25 miles northeast of San Diego.
In terms of battery storage, Arizona Public Service recently announced a first-of-its-kind 50-megawatt (MW) solar-fueled battery to the desert to provide clean power to Arizonans on hot summer days. This project will make Arizona home to one of the largest battery storage systems in the country. The innovative design models how the future of solar and storage can work together to deliver power to customers during peak hours.
