All over California, there's evidence of the state's goal to lead the country in renewable energy. Enormous farms of shiny solar panels have popped up across southern California, and gigantic wind turbines dot the landscape outside nearly all the major cities. There are less flashy—and less visible—investments in renewables going on, too. Tucked away in warehouses, trailers and industrial parks are lithium ion batteries that, if all goes well, will play a critical role in helping California hit its ambitious target: to have 50% of all electricity come from renewables by 2050.
Some green energy sources come with a built-in challenge: the wind and the sun can't be turned on and off at will. When it's windy and sunny, an abundance of energy may be harnessed—but any excesses go to waste. That's where batteries, the most common type of energy storage, come in. Batteries solve that problem by allowing utility companies to collect excess electricity and store it for times when the sun may not be shining or the wind not blowing.
“Networks care about reliability,” says Logan Goldie-Scot, an energy-storage analyst at Bloomberg New Energy Finance. “Energy storage is being viewed by network operators as a potential tool in their toolbox, and that hasn’t been the case up until now."
In 2013, California launched an aggressive effort to ramp up large-scale energy storage with an initial goal of building 1,325 megawatts of storage by 2020, the equivalent capacity of two average sized coal-fired power plants. Today, the state is already home to 36% of the country's battery storage capacity with projects continuing to open on a regular basis, according to a Climate Group report. Oregon and Massachusetts have since announced their own storage targets. Meanwhile, dozens of cities have made commitments to get 100% of their electricity from renewables.
