The Smart Electric Power Alliance (SEPA) announced Tuesday the release of its 2018 Utility Energy Storage Market Snapshot, its second annual overview of the energy storage market.

The report uses data and survey responses submitted directly by 137 U.S. utilities that represent more than 82 million customer accounts.

The study found that U.S. utilities interconnected 216.7 megawatts (MW), or 523.9 megawatt hours (MWh), of energy storage to the grid across 2,588 systems in 2017. By the end of the year, cumulative U.S. deployed energy storage was at 922.8 MW, 1,293.6 MWh across 5,167 systems.

“Nationally, the storage market is quite nascent,” SEPA Senior Research Associate Nick Esch said. “However, state policy action and regulatory action are creating opportunities in local energy storage markets. Hawaii and California are the leading markets today, but Maryland, Massachusetts, New Jersey, New York and Nevada will not be behind for long.”

The report also found that, in 2017, residential energy storage accounted for 13.3 MW, 29.3 MWh; non-residential added 59 MW, 139.7 MWh; and utility supply reported 144.4 MW, 354.9 MWh.

According to the survey, 64 percent of utilities are interested, planning or actively implementing behind-the-meter battery storage customer offerings. The report also noted the many storage technologies currently being deployed in demonstration projects across a wide range of applications.
