en.Wedoany.com Reported - China's Hainan Jia Zheng New Energy Co., Ltd. recently held a groundbreaking ceremony in the Xinglong District of Wanning for its 200MW/350.42MWh hybrid energy storage independent frequency regulation power station project. Wanning Municipal Party Committee Standing Committee Member and Deputy Mayor Liu Chao, Deputy Mayor Shen De'an, and others attended and laid the foundation.
The project is a key initiative for Wanning City, covering approximately 40 mu (about 2.67 hectares) with a total investment exceeding 500 million yuan. It involves the construction of an independent energy storage station primarily based on lithium batteries, along with supporting facilities such as a 220kV booster station. The project adopts energy storage integration technology from a Tsinghua University team and collaborates with Daqo Group's Chongqing Tailai Company, utilizing its energy storage converters. The station has a total scale of 200MW/350.42MWh and innovatively configures a 25MW/60-second supercapacitor system, achieving hybrid energy storage combining batteries and supercapacitors. General Manager Hu Chengyang stated: "This technology combination offers three major functions: efficient frequency regulation, peak shaving and valley filling, and promoting new energy consumption. It can enhance the frequency stability of the Wanning power grid and reduce the risk of new energy fluctuations."
Energy storage is regarded as a critical link in the new power system. Relevant departments in Wanning City proactively provided services during the project's preparation phase to ensure compliant progress. Chairman Huang Qianfei stated that the company will construct to high standards and strive for early commissioning, contributing to the development of Hainan's clean energy island and free trade port.
