On June 26, the 55MW/110MWh energy storage power station of China Resources Power successfully achieved full-capacity grid connection in one attempt, marking the first grid-side new-type energy storage project operated by China Resources Power Holdings Company Limited in Taizhou and also the first new-type energy storage power station put into operation in the Taizhou region.

The construction of grid-side new-type energy storage projects is a key task for ensuring power supply during peak summer demand in Jiangsu Province in 2024. It is of great significance in supporting the province's new energy consumption, promoting green transformation, facilitating high-quality development of the energy industry, and achieving carbon peaking and neutrality goals.

Located in the Science and Technology Park in Dainan township, this new-type energy storage power station covers a total area of approximately 41.346 acres with a total installed capacity of 55MW/110MWh. The project has installed 17 sets of 3.35MW/6.7MWh energy storage subsystems, which are aggregated and boosted to 110kV. A new 110kV line is constructed and T-connected to the 110kV Jixun-Guzhuang line, and then connected to the grid at the 220kV Guzhuang substation.

This energy storage power station is expected to have an average annual discharge capacity of approximately 36,000MWh and undergo 365 charging and discharging cycles annually, effectively enhancing the safety, economy, reliability, and flexibility of the regional power grid. Upon completion, the project will contribute to forming a 55MW new-type energy storage emergency peaking capacity in Taizhou before this year's peak summer demand period.
