Core Insights - The article highlights the operational efficiency and significance of the Sanxia Binhai Energy Storage Power Station, which is the largest string-type energy storage station in China, capable of discharging 400 MWh of clean energy into the grid [1][2]. Group 1: Operational Efficiency - The Sanxia Binhai Energy Storage Power Station performs an average of 1.5 charge and discharge cycles daily to meet the peak electricity demand in the Yangtze River Delta region during high-temperature periods [1]. - The station can release up to 800,000 kWh of clean energy during peak hours, which is equivalent to the daily electricity needs of 300,000 residents [1][2]. Group 2: Technological Advancements - The energy storage station acts as a "stabilizer" for the power system, providing rapid response capabilities to stabilize grid frequency fluctuations, thereby enhancing the consumption of renewable energy [2]. - As of the end of May, the station has completed 557 charge and discharge cycles, delivering a total of 18,600 MWh of energy to the grid, showcasing its high utilization rate [2]. Group 3: Cost Efficiency - The Sanxia Binhai Energy Storage Power Station operates independently, allowing it to directly connect to the grid and participate in power regulation services, which can reduce construction costs for renewable energy plants by over 10% [3]. - The "1-to-N" model allows wind and solar power plants to lease storage capacity, improving storage utilization rates to 88% [3].
