In Hami City of northwest China's Xinjiang Uygur Autonomous Region, the main body of an 1. 5 million kilowatts solar thermal energy storage project has been fully started.
What is the largest grid-forming energy storage station in China?
This marks the completion and operation of the largest grid-forming energy storage station in China. The photo shows the energy storage station supporting the Ningdong Composite Photovoltaic Base Project. This energy storage station is one of the first batch of projects supporting the 100 GW large-scale wind and photovoltaic bases nationwide.
By 2023, an additional 21.5 GW of energy storage had been installed, with over 95% of this capacity being lithium battery-based electrochemical storage (CIAPS, 2024). Several regions in China have already mandated wind and solar power plants to integrate a certain amount of energy storage capacity.
On March 31, the second phase of the 100 MW/200 MWh energy storage station, a supporting project of the Ningxia Power's East NingxiaComposite Photovoltaic Base Project under CHN Energy, was successfully connected to the grid. This marks the completion and operation of the largest grid-forming energy storage station in China.
In 2020, the total installed energy storage capacity was only 35.6 GW, with electrochemical storage accounting for 3.27 GW (CNESA, 2021). By 2023, an additional 21.5 GW of energy storage had been installed, with over 95% of this capacity being lithium battery-based electrochemical storage (CIAPS, 2024).
In the first three quarters of 2024, newly operational non-hydro energy storage installations reached 20.67 GW/50.72 GWh, representing year-on-year growth of 69% in power capacity and 99% in energy capacity.
What is energy storage capacity?
Energy storage capacity is anticipated to reach between 580 and 1400 GW, accounting for 8–20% of total renewable energy capacity, and will be primarily located in regions with a high share of PV generation.
