In 2023, the country's new installed power generation capacity will be 3700 million kilowatts, 1 more than the same period last year700 million kilowatts. Among them, the new grid-connected solar power generation capacity is 2200 million kilowatts, 1 more than the same period last year300 million kilowatts, accounting for 58 percent of the total installed capacity of new power generation5%。

By the end of 2023, the installed capacity of full-caliber power generation in the country will be 29200 million kilowatts, of which 15 are non-fossil energy power generation capacity700 million kilowatts, accounting for 50% of the first machine capacity in 2023, reaching 539%。
In terms of types, hydropower 4200 million kilowatts, including 50.94 million kilowatts of pumped storage; nuclear power 56.91 million kilowatts; Grid-connected wind power 4400 million kilowatts, of which 4 are onshore wind power000 million kilowatts, offshore wind power 37.29 million kilowatts; Grid-connected solar power 6100 million kilowatts.

The total installed capacity of grid-connected wind power and solar power generation in the country has increased from 7600 million kilowatts, continuously breaking through the 800 million kilowatts, 900 million kilowatts, and 1 billion kilowatts mark, reaching 10500 million kilowatts, a year-on-year increase of 386%, accounting for 360%, an increase of 6 year-on-year4 percentage points.
Thermal power 13900 million kilowatts, of which 11 are coal-fired power600 million kilowatts, a year-on-year increase of 34%, accounting for 39 percent of the total installed power generation capacity9%, falling below 40% for the first time, a year-on-year decrease of 40 percentage points.
In 2023, the power generation capacity of power plants above designated size in the country will be 891 trillion kWh, a year-on-year increase of 52%。Hydropower generation in power plants above designated size in the country decreased by 5% year-on-year6%。The lack of water storage in major reservoirs at the beginning of the year and the continued low precipitation in the first half of the year led to a year-on-year decrease of 22 percent in hydropower generation from power plants above designated size in the first half of the year9%；With the improvement of precipitation in the second half of the year and the low base of the same period last year, hydropower generation from August to December turned positive year-on-year.
In 2023, the power generation of thermal power and nuclear power in power plants above designated size in the country will increase by 6 percent year-on-year1% and 37%。In 2023, coal-fired power generation will account for nearly 60% of the total power generation, and coal power is still the main power source of China's electric power, effectively making up for the decline in hydropower output.
In 2023, the utilization hours of power generation equipment in power plants of 6,000 kilowatts and above across the country will be 3,592 hours, a year-on-year decrease of 101 hours.
In terms of types, hydropower was 3,133 hours, a year-on-year decrease of 285 hours, of which conventional hydropower was 3,423 hours, a year-on-year decrease of 278 hours; Pumped storage was 1,175 hours, a year-on-year decrease of 6 hours. 4,466 hours of thermal power, an increase of 76 hours year-on-year; Among them, 4,685 hours of coal-fired power were used, an increase of 92 hours year-on-year. 7,670 hours of nuclear power, an increase of 54 hours year-on-year. 2,225 hours of grid-connected wind power, an increase of 7 hours year-on-year. 1,286 hours of grid-connected solar power generation, a year-on-year decrease of 54 hours.
