华南地区抽水蓄能加快释放能源转型新动能

Core Viewpoint - The Qiongzhong Pumped Storage Power Station in Hainan is playing a crucial role in supporting the energy transition in the region, with significant increases in operational metrics during the Spring Festival and throughout 2025 [1][2] Group 1: Operational Performance - During the Spring Festival, the Qiongzhong Pumped Storage Power Station is expected to operate nearly 200 times, providing approximately 20 million kilowatt-hours of clean electricity to about 360,000 residents [1] - In 2025, the station recorded 7,117 operational starts, a 7.4-fold increase compared to the beginning of the 14th Five-Year Plan, and adjusted 1.47 billion kilowatt-hours of electricity, a 3.7-fold increase [1] - The frequency of operation for a single unit reached 6.5 times, making it the highest among pumped storage stations in the country [1] Group 2: Regional Context - The South China region, which occupies less than 5% of the national land area, has eight operational pumped storage power stations, accounting for nearly one-fifth of the national total installed capacity [1] - In 2025, the eight operational pumped storage stations in South China collectively achieved over 50,554 operational starts, a 23% year-on-year increase, despite the annual adjusted electricity remaining stable [2] - The increased operational frequency reflects the growing demand for short-term high-frequency starts to accommodate the integration of fluctuating renewable energy sources [2] Group 3: Technological Advancements - The operational model of pumped storage stations is evolving from traditional peak shaving to a more diversified approach, including supporting new energy consumption and facilitating vehicle-grid interaction [2] - The Guangdong centralized control center utilizes big data platforms for remote management of 38 units, allowing one operator to control three large pumped storage stations, achieving three times the efficiency of localized control [2] - The eight operational pumped storage stations in South China have a combined regulation capacity exceeding 25 million kilowatts, capable of absorbing up to 28 billion kilowatt-hours of clean energy annually, contributing to the energy transition [2]
