Utility-Scale Energy Storage: Technologies and Challenges for an Evolving Grid
The U.S. electricity grid was designed to generate electricity and deliver it almost immediately to customers—very little is stored. Adding more energy storage could have benefits, like helping utilities: Meet demand during supply disruptions; Recover faster after outages; Support renewable energy by storing power when natural sources—like wind and sunlight—are abundant and releasing it when they are not. But it can be hard to put storage technologies on a grid that wasn't designed for this use. Also, putting storage on the grid means navigating varied state rules and regulations. We offer policy options to address these and other challenges.
