US energy storage deployments rise by 80% in 2018, more in 2019

March 5, the US added 777 MWh of storage capacity in 2018, 80% more than in the previous year, and according to Wood Mackenzie Power & Renewables deployment of grid-connected storage in 2019 will jump to 1,681 MWh.

The fourth quarter of 2018 alone set a new record for megawatt hours deployed, mainly thanks to large front-of-the-meter (FTM) projects in Hawaii and Texas, according to the US Energy Storage Monitor 2018 Year-in-Review by Wood Mackenzie and the Energy Storage Association (ESA). Solar-paired and stand-alone storage systems across multiple markets and use cases resulted in a rise in FTM deployment.

In megawatt terms, capacity additions rose 44% to 310.5 MW, with California as the main market. Hawaii, New York and Texas also had a good year.

Wood Mackenzie forecasts annual megawatt deployments in the US of 642 MW in 2019 and a steady pace of growth through 2024, when 4,447 MW are expected to be added. The market size this year is seen to reach USD 951 million (EUR 838.8m), up from USD 486 million in 2018. By 2024, the size of the energy storage market is to reach USD 4.73 billion, according to the market research company.

Growth in the sector is being driven by new mandates, targets and supportive incentive structures for energy storage in different states, FERC Order 841, and new uses in the residential segment.

Brett Simon, senior storage analyst at Wood Mackenzie, explained that residential storage is moving beyond early adopters turning to battery systems for backup power. “We’re seeing the rise of opportunities for time-of-use shifting, solar self-consumption, and even some early examples of employing residential storage for grid services, such as by Green Mountain Power in Vermont and Liberty Utilities in New Hampshire,” Simon said.

The share of behind-the-meter (BTM) systems in 2018 megawatt deployments was 53% and the residential storage market quadrupled year-over-year.
