In the first half of 2021, all units of Wudongde Hydropower Station will be put into operation to generate electricity. The first batch of units of Baihetan Hydropower Station were put into operation to generate electricity, marking another important milestone in the construction of the hydropower station.

In 1949, some hydropower stations were strengthened and strengthened; in 1980, the reform of the hydropower construction system entered an exploratory period; starting in 2000, a competition mechanism was introduced in the hydropower field, cascade development was developed in basins, and hydropower construction was accelerated the pace; the "13th Five-Year Plan" comprehensively lays out the five-year development of the hydropower industry; the "14th Five-Year Plan" requires accelerating the layout of hydropower stations and promoting clean energy.

It takes many years to sharpen a sword. At present, my country's long industrial chain of hydropower station construction, hydropower operation, and downstream power grid connection is stable. In the first half of 2021, my country's installed hydropower capacity was 380 million kilowatts, a year-on-year increase of 4.9%; the water energy utilization rate in major river basins was 98.43%. As a large-scale platform for clean renewable energy, hydropower has seen steady increases in installed capacity and power generation. my country has abundant water energy resources, and there is still a lot of room for development in the future, and the scale of hydropower installations continues to advance.

　The advancement of wind power in the central and eastern regions is diverging

The installed capacity of wind power is 290 million kilowatts, a year-on-year increase of 34.4%, and the national average The wind power utilization rate was 96.4%, an increase of 0.3 percentage points over the same period.

Wind power stations are advancing from resource concentration areas to load concentration areas, and gradually moving to the central and eastern regions, showing a divergent trend. From January to June 2021, the newly installed wind power capacity in the central, eastern and southern regions accounted for approximately 59%, and the "Three North" regions accounted for approximately 41%. Among them, East China and Central China have more newly installed capacity, reaching 1.08 million kilowatts and 1.88 million kilowatts respectively. Winds in North China and Northwest ChinaThe cumulative installed capacity accounts for more than half of the country, reaching 28% and 24% respectively.

Looking back at the history of wind power: During the "Eleventh Five-Year Plan" period, the industry experienced explosive growth, and wind power equipment manufacturing increased significantly; during the "Twelfth Five-Year Plan" period, the national wind abandonment rate increased, and the installed wind power capacity increased. During the "Thirteenth Five-Year Plan" period, wind power curtailment and power curtailment have eased, and owners' demand for installed capacity has increased. During the "14th Five-Year Plan" period, wind farm construction costs have dropped, the competitiveness of wind power generation has significantly improved, and the economic demand for wind power has been further released.

At present, the price of wind power equipment is relatively low, and the overall trend of wind energy power generation is improving.

Nuclear power technology continues to upgrade and enters the advanced "track"

"Hualong One" adopts multiple defense systems , 177 fuel assembly reactor core, single stack layout, double-shell structure, realizing the principle of defense in depth and greatly improving our country's nuclear technology level.

Since the 1970s, through the reform and innovation, continuous struggle, and bold practice of several generations of nuclear power workers, my country’s nuclear power has achieved a transformation from weak to strong, small to large, and from small to large. Only by following the leap of running parallel to each other can nuclear power plants such as "Hualong One" be born.

In 1974, my country independently designed and built its first nuclear power plant, the Qinshan Nuclear Power Plant; in 1993, it introduced two sets of nuclear power units and established the Daya Bay Nuclear Power Plant. As of June 2021, my country's nuclear power installed capacity was 53.26 million kilowatts, a year-on-year increase of 9.2%. After decades of exploration, nuclear power plants have gone from immaturity to maturity, from technological blanks to overcoming difficulties, and have broken through important difficulties in the construction of clean energy systems.

As a safe, clean and efficient energy, nuclear power is an important branch of my country’s energy supply system. During the "Twelfth Five-Year Plan" period, the development of nuclear power was included in the national plan; with the rapid development of science and technology, nuclear power staff relied on artificial intelligence, big data and other technologies to ensure construction quality and safety; during the "14th Five-Year Plan" period, coastal nuclear power plants will Our country will continue to develop safely and steadily.
