Despite not quite hitting the numbers anticipated, the US energy storage market set a new record in the fourth quarter of 2021, with new system installations totaling 4,727MWh, according to Wood Mackenzie and the American Clean Power Association’s (ACP) latest US Energy Storage Monitor report, released today. And it could have been so much more. Due to supply chain challenges, over 2GW of grid-scale capacity originally slated to come online in Q4 2021 were delayed to 2022 and 2023. Residential storage had its strongest quarter to date with 123MW installed, (the previous quarterly record was 110MW in Q1 2021). Despite limited battery supply, the segment still managed to grow 85% between 2020 and 2021 in MWh terms, and this is in part due to solar-plus-storage sales in markets outside of California. The national annual total of installed residential energy storage amounted to 436MW. By 2026, annual installations in the residential segment are expected to hit 2GW / 5.4GWh, with California, Puerto Rico, Texas, and Florida leading the way. The residential forecast assumes that the NEM 3.0 proposed decision in California will go into effect as written, although WoodMac analysts said that this is not a certain outcome. If it does not, the forecast would be reduced ~5% annually from 2023.
