This week, the prices of DC-side battery cabins slightly decreased. The average price of a 5 MWh DC-side battery cabin was 0.427 yuan/Wh, while the average price of a 3.44/3.77 MWh DC-side battery cabin was 0.437 yuan/Wh.

This week, the price of DC-side battery cabins slightly decreased. The average price for a 5MWh DC-side battery cabin was 0.427 yuan/Wh, while the average price for 3.44/3.77MWh DC-side battery cabins was 0.437 yuan/Wh. In Q2 of 2025, with the successive release of Document No. 394 (spot electricity market) and Document No. 650 (direct connection of green electricity), provinces such as Inner Mongolia and Xinjiang implemented subsidies for ESS installations, encouraging market participation in the construction of grid-side ESS facilities and jointly participating in reforms such as the electricity mechanism and electricity trading. This led to an increase in domestic ESS demand, accelerated shipments of battery cells and integrations, coupled with a reduction in the cost of ESS system components, resulting in a continuous decline in the price of DC-side battery cabins. SMM predicts that the price of DC-side battery cabins may continue to decline slightly in the short term.

On July 7th, the winning bid result for the EPC general contracting tender of the Dapu Xianeng 200MW/400MWh standalone ESS power station demonstration project was announced. The project is planned to be constructed in Meizhou City, Guangdong Province, covering a total area of approximately 36.14 mu. The ESS construction scale is 200MW/400MWh, with LFP batteries used for energy storage. Both the battery system and the power conversion system of the energy storage station adopt an outdoor prefabricated cabin layout scheme. The bid winner's offer was 3,399.48093 million yuan, with a winning bid unit price of 0.85 yuan/Wh after conversion.
