Research shows that 4.2GW of battery energy storage systems will be newly deployed in the United States in 2021

The U.S. will add nearly 4.2 GW of battery storage capacity to the grid in 2021, according to a recent survey by Bloomberg New Energy Finance, which also focused on growing U.S. lithium-ion battery manufacturing capacity.


According to Bloomberg New Energy Finance's "Sustainable Energy Profile in the U.S.," compiled for the U.S. Sustainable Energy Business Council, this number exceeds deployments in previous years combined.


Projects such as SK Innovation and Ford's Blue Oval City will significantly increase U.S. lithium-ion battery manufacturing capacity


The US will have 4,417MW of battery storage installed in 2021, up 360% from last year, although Bloomberg New Energy Finance says only 77% of this is "confirmed", the rest is "confirmed" estimated". However, the cumulative installed capacity of battery energy storage systems in the United States has reached 6.6GW. The report also highlights two main drivers of growth in energy storage deployments.


First, there is a growing demand for battery energy storage systems due to the increase in renewable energy on the grid. And on the regulatory side, Federal Energy Regulatory Commission (FERC) Order 841, issued in 2018, provided a further boost to the industry by removing barriers preventing energy storage systems from fully participating in these markets.


Although the report warns, as the adoption rate of battery energy storage systems increases, so does the pressure to have a meaningful system-level impact on the grid and electricity markets. Today, about 80% of the installed energy storage capacity in the United States comes from pumped storage power generation facilities, but there has been no new pumped storage power generation facilities since 2004, and the current installed capacity is about 22.5GW.


The Bloomberg New Energy Finance report, which covers all segments of the energy storage market including residential energy storage systems, saw 19,607 deployments in the first nine months of 2021, three more than in the same period in 2020 and 2019, respectively. 2/1 and 1.5 times.


U.S. lithium-ion battery manufacturing capacity has also increased, growing to 60GWh/year by 2021. It is expected to reach nearly 100GWh/year by the end of 2022, although the report predicts no further development.


However, the report states that SK Innovation/Ford's Blue Oval City and Samsung SDI/LG Energy Solution's joint ventures will add 129GWh and 40GWh of batteries in 2027 and 2025, respectively. These are almost three times the current manufacturing capacity.


The broader briefing and methodology of the Bloomberg New Energy Finance report provides a more positive reading than a recent survey by the American Clean Energy Council (ACP), which only covers utility-scale deployments and said last year's clean energy Deployed capacity fell 3% to 27.7GW.


Overall, new U.S. renewable energy capacity deployments rose 5% in 2021 to 37.3GW, Bloomberg New Energy Finance said. This figure does not include battery energy storage systems, which the American Clean Energy Council (ACP) has released for 2021 deployment figures are lower.
