甘肃光热发电装机规模居全国首位

Core Viewpoint - Gansu Province is set to achieve a solar thermal power generation capacity of 620,000 kilowatts by October 13, 2025, leading the nation in this sector [1] Group 1: Solar Thermal Power Technology - Solar thermal power generation utilizes molten salt and other media to absorb solar thermal energy, converting it into steam energy and then into electrical energy via turbines, differing from photovoltaic solar power [1] - The technology allows for energy storage using molten salt, enabling power generation during nighttime and cloudy days, thus addressing the limitations of photovoltaic systems [1] Group 2: Project Examples and Performance - The Dunhuang Solar Power Industrial Park's 100 MW molten salt tower solar thermal power station exemplifies this technology, using a large array of heliostats to focus sunlight on a receiver, heating molten salt to 540°C-560°C for energy storage [1] - The power station can generate up to 2 million kilowatt-hours in summer and a minimum of 1.2 to 1.3 million kilowatt-hours in winter [1] Group 3: Grid Integration and Benefits - Solar thermal power stations can respond to grid load adjustments similarly to traditional thermal power plants, aiding in peak shaving and frequency regulation while maintaining a fully green energy profile [1] - Gansu Province hosts several solar thermal power projects, including the 100 MW molten salt tower project, demonstrating a commitment to renewable energy integration [1]
