江苏首个区域分散建设电网侧储能电站并网运行

Core Viewpoint - The Jiangsu Suqian Zhonghe East Line New Energy 49.8 MW grid-side energy storage power station has commenced operation, marking Jiangsu's first regionally decentralized grid-side energy storage project [1] Group 1: Project Overview - The energy storage station is located within four decommissioned substations in Siyang County, Suqian City, utilizing a "waste-to-treasure" approach to address the challenges of centralized energy storage stations in flexibly absorbing distributed photovoltaic power generation [1] - The energy storage station is expected to achieve an annual charge and discharge volume exceeding 40 million kWh, resulting in a reduction of approximately 50,000 tons of carbon dioxide emissions and saving about 16,000 tons of standard coal consumption annually [1] Group 2: Industry Context - In recent years, renewable energy, particularly wind and solar power, has rapidly developed in Jiangsu, with some areas facing insufficient renewable energy consumption capacity, which affects grid stability [1] - As of the end of October this year, Suqian City has a total installed capacity of over 6.652 million kW of renewable energy, accounting for about 80% of the city's total power generation capacity [1] Group 3: Technological Innovation - The energy storage station employs an innovative "collection station + sub-station" communication architecture, where one storage station acts as the master station, and the remaining sub-stations are interconnected for data sharing, reducing initial construction costs by over 10 million yuan compared to traditional energy storage stations [1]
