According to survey data recently released by the American Clean Energy Council (ACP), the United States deployed about 5GWh of battery energy storage systems in the first half of 2022, an increase of one-third compared with the same period last year, while the deployment of wind and solar power generation facilities The installed capacity has dropped by 50% to 70%.
In its quarterly report covering all renewables, the American Clean Energy Council (ACP) said 14 new battery energy storage projects were deployed in the U.S. in the second quarter, totaling 992MW/2,468MWh, a 13% increase compared to the same period last year.
The US installed 758MW/2,537MWh of battery storage systems in the first quarter, a 173% increase compared to the same period last year. According to the survey data of research firm Wood Mackenzie, the storage capacity of battery energy storage systems installed in the United States in the first quarter was slightly lower, at 2,339MWh.
This means that a total of 1,751MW/5,015MWh of battery storage systems were deployed in the US in the first half of this year. The American Clean Energy Council (ACP) doesn't say it's a year-over-year increase, but using the two quarters data shows that storage deployments have grown by about a third.
The largest battery storage project installed in the US in the second quarter was Vistra's DeCordova battery storage system in Texas, with a scale of 260MW/260MWh. The largest energy storage capacity is an 800MWh Diablo battery energy storage system developed by LS Power in California.
As of the end of June, the cumulative installed capacity of battery energy storage systems in the United States was 6,471MW, with a total energy storage capacity of 16,792MWh.
Despite the growth in both quarters, more than 1GW of battery storage was deployed in the fourth quarter of 2021 in the strongest quarter on record, according to the annual report released by the American Clean Energy Council (ACP).
During the quarter, about 327MW of solar-plus-storage projects were commissioned. According to the American Clean Energy Council (ACP), solar power and energy storage systems account for three-quarters of the 9,023 MW of installed hybrid capacity in the United States.
Despite an increase in battery storage deployments in the first half of the year, clean energy deployments overall fell 25%, the largest drop in six months since 2018, the American Clean Energy Council (ACP) said.
The decline in clean energy capacity deployed in the second quarter of this year was even greater, falling by 55%. The battery energy storage sector was the only sector to grow, accounting for 31% of the 3,188MW of clean energy installations installed during the same period. The installed capacity of wind power generation facilities decreased by 78% year-on-year, and the installed capacity of solar power generation facilities decreased by 53% year-on-year.
This is partly due to supply chain constraints and grid connectivity issues that have delayed projects. According to the American Clean Energy Council (ACP), there are now 32 GW of clean energy projects delayed, of which 64% are solar, 13% battery storage and 23% wind.
