US adds 2,399 MWh of grid-scale energy storage in Q1

The US has installed 2,399 MWh of grid-scale energy storage in the first three months of 2022, a record for a first quarter and four times the year-ago volume, according to a report released on Wednesday by Wood Mackenzie and the American Clean Power Association (ACP).

The record was achieved in spite of ongoing procurement challenges and project delays, the analyst firm said. It added that the anti-dumping and countervailing duties (AD/CVD) solar tariff investigation initiated in March significantly reduced forecasts for hybrid projects in 2022.

“The Biden Administration’s recent decision to pause AD/CVD solar tariffs for two years restores predictability to both the solar and energy storage markets,” said John Hensley, vice president of research and analytics at ACP. “With well over 50% of utility storage projects being paired with solar farms, this important executive action will help the energy storage market continue to accelerate,” added Hensley.

The US energy storage sector installed a total of 955 MW and 2,875 MWh across all segments in the initial quarter of 2022.

Residential storage deployment hit a record 334 MWh across over 20,000 systems, ahead of the previous record of 283 MWh in the fourth quarter of 2021.

By 2026, Wood Mackenzie expects the residential storage segment to grow by 5.7 GWh per year. On the other hand, non-residential storage is forecast to expand by 1 GW annually by then.
