China's largest photothermal power plant is spearheading a "new type of power system" in the country. The photothermal power plant in Dunhuang City of northwest China's Gansu Province covers over 1.4 million square meters, with 12,000 heliostats surrounding a 260-meter-high heat-absorbing tower. In contrast to photovoltaic power plants, a photothermal power plant can intelligently control its numerous heliostats and store solar energy through high-temperature molten salt, releasing it in a planned manner to ensure 24-hour power provision.
