U.S. energy storage market grows 162% year-on-year in the second quarter of 2021

　　According to the latest report released by the research organization Wood Mackenzie and the American Energy Storage Association (ESA), the United States will deploy an energy storage system with an installed capacity of 345MW in the second quarter of 2021. This is an increase of 162% compared to the same period in 2020.

　　The growth momentum of the energy storage market continues to increase because the installed capacity of the energy storage system deployed and opened in the United States in the second half of this year will set a new record. Wood Mackenzie expects to put projects into operation that worth more than US$5 billion in energy storage in 2021.

　　Although the U.S. energy storage market is gaining momentum, the residential battery energy storage market has declined slightly. This is the first decline in this segment in nine quarters (since the fourth quarter of 2018). Although the number of new residential energy storage suppliers is growing rapidly, due to battery production constraints (such as the shortage of Tesla's Powerwall battery energy storage system), the growth of this market segment is hindering.

　　The growth of the community energy storage market in Massachusetts has caused the deployment of non-residential energy storage markets composed of on-site energy storage systems and community-scale energy storage systems to increase by 31% in the second quarter of this year.

　　In the US grid-side (FTM) energy storage market, 218MW/729MWh energy storage systems were deployed in the second quarter of 2021, with California, Texas, and Arizona leading the market. California continued to lead the development of the grid-side market in the second quarter, where most of the installed capacity in the second quarter came from the 100MW/400MWh Saticoy energy storage system deployed by Arevon in Ventura County. The solar + energy storage projects deployed in Texas and Arizona also increased the installed capacity of the grid-side energy storage system in the second quarter.

　　Wood Mackenzie Senior Energy Storage Analyst Vanessa Witte pointed out, "The US energy storage market is still expected to set a new record this year, further proving that battery energy storage systems are becoming more and more popular in the electricity market, and emphasized its importance to the energy transition. ."

　　Jason Burwen, interim chief executive officer of the American Energy Storage Association, said, “The deployment of energy storage has achieved both the decarbonization and resilience goals of the United States. According to the research report on the future development of the solar power generation industry released by the Department of Energy a few days ago, it is estimated that by 2035, the United States will need to deploy solar power generation facilities with an installed capacity of up to 400GW.

　　Energy storage systems can also ensure that power transmission can withstand increasingly frequent and intense weather interruptions, such as the heat waves and hurricanes that occurred in the United States last summer.

　　Investment tax credits have promoted the development of industries such as solar and wind energy, and have the same effect on the energy storage industry. "

　　Continued to strengthen in the second quarter of this year, the US government introduced a number of new incentives for residential and non-residential energy storage systems.

　　The investment tax credit (ITC) for solar power generation facilities has been postponed, and the independent deployment of energy storage systems will receive the investment tax credit (ITC). The energy storage industry is waiting for Congress to pass these two favorable policies in time.
