全球能源转型下我国水电发展新趋势

Core Viewpoint - The energy development direction in China is shifting towards clean, low-carbon, safe, and efficient systems, with a significant transformation in the power supply structure from fossil fuels to non-fossil energy sources [1][27]. Group 1: Current Status of Hydropower Development - Hydropower plays a crucial role in China's energy structure, with an expected generation of 1,274.25 billion kWh in 2024, accounting for 13.53% of total power generation [2]. - From January to October 2025, hydropower generation reached 1,131.12 billion kWh, slightly increasing its share to 14.03% [2]. - As of October 2025, the total installed capacity of hydropower is 440 million kW, representing 11.83% of the total power generation capacity in China [4]. Group 2: Installed Capacity and Growth Trends - The total installed power generation capacity in China reached 3,752 million kW by October 2025, a year-on-year increase of 17.45% [4]. - Hydropower's installed capacity growth has slowed, primarily due to the saturation of high-quality hydropower resources and the longer construction cycles compared to wind and solar power [6]. - As of October 2025, conventional hydropower installed capacity is 380 million kW, with a 70.11% development rate of technically exploitable capacity [8]. Group 3: Economic Advantages of Hydropower - Hydropower is recognized for its flexibility and reliability, with a rapid startup time of 1-2 minutes from a standby state to full load [9]. - The average cost of hydropower generation is between 0.1 to 0.3 yuan per kWh, which is competitive compared to other energy sources [16]. - The average on-grid price for hydropower is transitioning from planned pricing to market-based pricing, currently at 0.3 yuan per kWh, which is lower than coal power [16][22]. Group 4: Future Projections and Policy Directions - By 2030, the total installed capacity of conventional hydropower is projected to reach 420 million kW, with an average annual growth rate of 2.02% from 2025 to 2030 [23]. - The demand for flexible adjustment resources in the power system will increase as the share of renewable energy rises, positioning hydropower as a stabilizing force in the energy mix [27]. - The development of pumped storage hydropower is expected to double by 2030, reaching 120 million kW, further enhancing the role of hydropower in energy regulation [12].
