The US Is Filled With Batteries: It Already Exceeds 12 GW Of Installed Capacity

It installed a record 4.8 GW in 2022, and installations are expected to reach almost 75 GW between 2023 and 2027.

The US energy storage market installed 4.8 gigawatts (GW) of capacity in 2022, nearly equal to the combined 2020 and 2021 installed capacity of 5 GW, making it a record year for battery storage.

“Energy storage had its best year to date in 2022. Cumulative utility-scale storage capacity increased by 80%. While we did see a slight drop in installations towards the end of the year, the trend is clear: energy storage is on a rapid growth curve and is already a key component in building a resilient grid that supports abundant clean energy.” said John Hensley, vice president of Research and Analysis for the American Clean Power Association (ACP).

According to the latest report U.S. Energy Storage Monitor from ACP and Wood Mackenzie, the market added 1,067 megawatts (MW) across all segments in the fourth quarter of 2022, making the quarter only the fifth-highest for installations, down 33% from the fourth quarter of 2021, which is the highest on record.

Break in the last quarter

Findings from the new report show that the US grid-scale (also called utility-scale) segment installed a total of 848 MW in Q4 2022, down from installations greater than 1 GW. both in the second and third quarters of this year.

The decrease in installed capacity was largely due to supply chain and interconnection constraints. These headwinds continued to affect the project pipeline, with more than 3 GW of projects scheduled to come online in the fourth quarter delayed or cancelled.

However, the residential storage segment increased by 11% compared to the third quarter and broke another record with 171 MW installed, 17 MW higher than the figure for the same quarter of 2022. Installed capacity in this segment increased in all quarters 2022, confirming sustained demand for standby and resilient residential power.

Super growth in the future

Deployment in the community, commercial and industrial (CCI) storage segment rebounded from a significant drop in Q3 2022 with 48 MW installed in Q4, an increase of 78%. Traditionally strong states in the CCI segment, such as New York, rebounded to higher deployment levels that boosted fourth quarter numbers.

“Despite the slow fourth quarter, total installations in 2022 were 44% higher than in 2021. Grid-scale installations were up 7% year-on-year, CCI installations 3% and residential experienced the highest growth, with an increase of 36%. Looking ahead, we expect the US storage market to install almost 75 GW between 2023 and 2027. Grid-scale installations account for approximately 60 GW, or 81% of the new capacity added,” said Vanessa Witte, senior analyst on the team. Wood Mackenzie energy storage facility.

Forecasted capacity for the Grid and CCI segments will more than double by 2023, in part due to strong demand for storage and the start-up of projects delayed from 2022. Wood Mackenzie also expects residential capacity to increase by approximately 88%. in 2023, with four times as much residential storage to be installed in 2027 compared to 2022 volumes.

California, the king of batteries

“California continues to have the largest residential facility market share through 2027 at 47%, far dwarfing any other state. Puerto Rico continues to be the second until 2027, with a share of 11%,” said Witte.

The volume of projects in the interconnection queue from 2023 to 2028 decreased approximately 10% from the last quarter, as a result of the filtering of requests by independent system operators (ISOs) and the withdrawal of requests by from promoters, now that the rush to secure queue positions has eased a bit.

According to the report, 7 GW of projects with an original commercial operation date of 2022 have been deferred to later years or canceled outright, likely due to rising costs or the inability of developers to procure the equipment in a timely manner. .

A relief in battery prices is looming on the horizon as commodity prices have started to decline after prices for battery precursors such as lithium carbonate peaked in the fourth quarter. quarter. Systems costs are expected to decline in 2023, although other issues remain, such as supply delays and an increasingly tight labor market.
