US energy storage market nearly doubled in 2018, report says

Dive Brief:

  • U.S. energy storage deployment nearly doubled in 2018 as the nation installed 350.5 MW, 777 MWh — over 80% more than was deployed in 2017 in terms of megawatt-hours, according to a new report.

  • Behind-the-meter (BTM) storage accounted for 53% of the total deployment in megawatts while front-of-the-meter (FTM) installations accounted for 47%, according to the U.S. Energy Storage Monitor 2018 Year-in-Review. FTM installations often had durations of four hours or more.

  • Report authors from Wood Mackenzie and the Energy Storage Association expect the storage market to double in 2019, deploying 1,681 MWh. By 2024, they expect annual deployments to exceed 4.4 GW.

Dive Insight:

The record year for storage in 2018 reflects the increasing competitiveness of batteries and enhanced utility familiarity with the new technology.

Growth in FTM storage was especially pronounced in the fourth quarter, when the U.S. deployed 352 MWh of batteries. Many of those installations were used for capacity, the authors wrote, and had durations of more than four hours.
