On May 15, the Hainan Talatan 255 MW × 4h energy storage project, developed by China Energy Investment Corporation Co., Ltd. (CHN Energy)’s Qinghai Gonghe Company, achieved a significant milestone as its final module was successfully connected to the grid.
This successful connection signifies the completion of the corporation’s largest electrochemical energy storage power station, solidifying its position as a key player in the energy sector.

Located in the photovoltaic industrial park of Gonghe County, Hainan Tibetan Autonomous Prefecture, Qinghai Province, the project covers an area of approximately 93.5 mu (6.23 hectares). It features a combination of string-type, high-voltage direct-mount, and centralized energy storage systems, comprising 56 storage units and two high-voltage cascaded grid-forming subsystems.
Once fully operational, the project is expected to deliver an annual charge volume of approximately 285,600 MWh and reduce carbon dioxide emissions by about 378.14 tons per year. It will significantly enhance the regional power system’s peak-shaving capacity and improve the flexibility of source-grid-load-storage coordination.
The project plays a vital role in supporting Qinghai’s renewable energy integration and energy structure optimization, contributing to the development of a clean, low-carbon, safe, and efficient energy system.
