Getting to 50 GW? The Role of FERC Order 841, RTOs, States, and Utilities in Unlocking Storage's Potential
February 22, 2018
Published by The Brattle Group, Inc.

The study examines the current state and potential future growth of the U.S. market for electricity storage, and finds that storage market potential could grow to 50,000 MW over the next decade if storage costs continue to decline and state regulatory policies build on the recently-issued FERC Order 841 to remove barriers that prevent storage resources from realizing multiple value streams.
