China National Nuclear Huineng Chongqing Xiyong Comprehensive Bonded Zone 100MW/200MWh Energy Storage Power Station Project is connected to the grid

On July 25, all battery compartments of CNNC Huineng's 100MW/200MWh energy storage power station project in Chongqing Xiyong Comprehensive Bonded Zone completed rated charging and discharging, marking the full capacity grid-connected operation of the company's first prefabricated large-scale energy storage project.

The project took only 86 days from construction to full capacity grid connection. It is the latest signed and earliest grid-connected project among Chongqing's eight energy storage demonstration projects this year, setting a number of new records in investment decision-making, project construction, and project grid connection for similar projects, fully demonstrating the "China Nuclear Speed" and "China Nuclear Quality". The commissioning of the project will effectively ease the power supply pressure during the "peak summer" period, enhance the peak and frequency regulation capabilities of the power grid, and ensure the safe and stable operation of the power grid.

The project deepens the implementation of the prefabricated cabin technology model for power stations, comprehensively improving the safety, quality, efficiency and benefits of power station construction. The entire station of the project adopts a station construction idea based on prefabricated cabins, and all primary and secondary equipment are placed in cabins. The primary and secondary equipment of the entire station follows the concept of "factory processing and modular construction", and the entire station adopts prefabricated cabin combination equipment to achieve plug-and-play of primary and secondary equipment. At the same time, the electrical equipment and prefabricated cabins in the substation are preinstalled and debugged in the factory, and the whole is sent to the site in sections for splicing and installation. By giving full play to the advantages of prefabricated cabin booster stations, such as small footprint and less civil construction, the construction safety and engineering construction efficiency are effectively improved, the equipment operating environment is greatly improved, and the life of primary and secondary equipment and system quality are comprehensively improved.

In the future, CNNC Huineng Chongqing Company will continue to actively promote the development and construction of new energy projects in Chongqing, and contribute "CNNC strength" to Chongqing's power supply and energy construction.
