The Tehachapi Experiment in Energy Storage

California Takes Lead In Developing Energy Storage

Climate Central, January 13, 2015

The city of Tehachapi, near the crest of a mountain pass in southern California, is a bridge between the Mojave Desert and the San Joaquin Valley — a blustery area serving as an ideal site for a wind farm.

It’s also the site of the Tehachapi Energy Storage Project, an experiment in storing wind power in giant lithium-ion batteries, so far the largest energy storage project of its kind in North America. The project is Southern California Edison’s $50 million effort to demonstrate how energy storage can improve the region’s power grid and help reduce greenhouse gas emissions.

With that and similar projects in the works, California is quickly becoming the U.S. leader in energy storage after the state’s 2013 mandate that its largest utilities have 1,325 megawatts — roughly enough for 1 million homes — of electricity storage operating by 2024 as one step to fight climate change. Storage will help the state reach its climate goal of having 50 percent of its electricity supplied by renewables by 2030.
