Update: California's Energy Storage Mandate

Randy J. Hill and Elliott J. Williams at Renewable Energy World have the update on California's energy storage mandate. In particular, they look at the effects of AB 2514, which is pushing California utilities to look at technologies beyond pumped storage hydroelectricity.

Although a handful of storage technologies are getting a big boost from that effort, there is little doubt that roughly 75 percent of the state’s energy storage needs in the coming decades will be met by pumped storage hydro, the traditional—and still the most economical—storage solution.
