Last year, SCE connected 56 MW of battery storage to the grid. This includes residential, commercial and utility-supply energy storage. SCE also connected 547 MW of solar energy to the grid through new and expanded residential and commercial solar installations as well as through utility-supply sources. SCE has placed among the top-10 utilities for solar every year since the alliance began publishing its solar rankings in 2007.
Last October, SCE shared its plan to meet California’s GHG reduction goals and reduce air pollution. To achieve this, the utility will need to add 30 GW of additional renewable capacity, including wind, solar, geothermal and hydro, to California’s electric grid by 2030.
The addition of large-scale renewables, along with more than 3,600 of SCE’s customers adding rooftop solar every month, makes energy storage increasingly important. Battery storage is a key part of SCE’s strategy to clean the power system along with supporting a sustainable solar industry and customers who choose to go solar.
