The global new energy storage sector is experiencing a period of rapid expansion. According to CNESA, the cumulative installed capacity of new energy storage worldwide reached 45.7 GW in 2022, with annual new installations reaching 20.4 GW. China, Europe, and the US will continue to lead the global energy storage market in 2022, accounting for 86% of the global market. This represents a 6 percentage point increase from the same period in 2021. The compound annual growth rate (CAGR) of new installed capacity for electrochemical energy storage is projected to be 63.7% from 2022 to 2027. CNESA also reports that the global installed capacity of electrochemical energy storage reached approximately 97 GWh in 2022 and is expected to reach 1,138.9 GWh in 2027, with a CAGR of 63.7%.
In the domestic market, the prices of lithium carbonate experienced a rapid decline from January to March in 2023. This led to an acceleration of domestic energy storage bidding projects since March. According to statistics from the energy storage and power market, the bidding capacity of domestic electrochemical energy storage amounted to approximately 27 GWh from January to May 2023, with the domestic capacity in May alone reaching around 9 GWh.
In the US market, the installation of energy storage projects from January to May 2023 was impacted by fluctuations in supply chain prices and interest rates. As a result, the process of installation and grid-connection projects has been relatively slow. However, in terms of grid connection planning, as of April 2023, it is expected that 9 GW of electrochemical energy storage will be connected to the grid in 2023, followed by 13.5 GW in 2024. Additionally, 2023 is expected to witness the peak of actual installation and grid connection projects in the US.
