Hydropower has been a strategic boon to economic prosperity in Sichuan, which has huge potential to harness this renewable energy source to accelerate economic growth. January 5, 2022, Sichuan Province carbon Peak implementation plan issued. The plan is put forward to develop hydropower in a scientific and orderly way. We will speed up the construction of the "three rivers" hydropower bases on the Jinsha River, Yalong River and Dadu River, and promote the construction of large and medium-sized hydropower projects in other river basins in an orderly manner. Efforts will be made to adjust and optimize the structure of hydropower development, and priority will be given to the construction of hydropower stations in reservoirs with seasonal adjustment capacity. In the concentrated areas of new energy development and power load centers, combined with the reuse of water resources in water conservancy projects, pumped storage power stations will be planned and built. Keywords: Capital construction, infrastructure construction, domestic engineering news, planning investment

Construction of Yebatan hydropower stations on the Jinsha River, Kara on the Yalong River, and Shuangjiangkou hydropower stations on the Dadu River was accelerated, and new hydropower stations were built on the Xulong and Gangtuo Hydropower stations on the Jinsha River, second-level Yalong River Gen, and Danba hydropower stations on the Dadu River. We will comprehensively optimize hydropower design, construction and management to effectively reduce the cost of hydropower development. During the 14th and 15th Five-Year Plans, the installed capacity of hydropower was increased by 25 million kW and 13 million kw respectively, and the renewable energy system, dominated by hydropower, was further consolidated.

We will promote the north and west extension of the 1,000-kilovolt extra-high voltage AC power grid, and improve and expand the Sichuan-Chongqing extra-high voltage AC ring network. Centering on "inbound", we will speed up the construction of channels for foreign electricity to enter Sichuan. Highlighting the complementarity with the thermal wind and light power supply of Northwest province and the water and light power supply of Tibet region, planning and building the UHV DC project of the power supply from Gansu to Sichuan, the power supply from Tibet to Sichuan, and the power supply from Xinjiang to Sichuan, so as to improve the interworking level and mutual benefit capacity of Sichuan power grid, Northwest power grid and Tibet power grid. Centering on "catch" to enhance the power transmission unit network capacity. By 2025, the power retention capacity of external transmission units will increase by 7.7 million kW to 19.2 million kW.
