The U.S. energy storage market is primed to grow at a rapid pace. A study by IHS Markit forecasts that the U.S. grid-tied energy storage market will nearly double in 2019 – from 367 MW in 2018 to 712 MW this year – which does not include behind-the-meter energy storage that would add several hundred MW of deployed energy storage to the forecast for 2019. This significant expansion is poised to occur against a backdrop of regulatory changes in federal and state incentive programs, cost improvements and advances in monetization of energy storage. These current and anticipated trends affecting the U.S. energy storage market will have a significant influence on how industry participants choose when, where and how to invest in and develop energy storage technology.
