On July 28, the National Energy Administration held a regular press conference in Beijing to release the energy economic situation in the first half of 2021, the status of renewable energy grid connection, introduce the National Energy Administration’s power flood prevention and disaster relief and peak summer conditions, and interpret the "About Guiding Opinions on Accelerating the Development of New Energy Storage.

Wang Dapeng, deputy director of the New Energy and Renewable Energy Department, briefly introduced China's renewable energy development in the first half of 2021 from five aspects.

Overall development of renewable energy

In the first half of 2021, the National Energy Administration will conscientiously implement the new strategy of "Four Revolutions, One Cooperation" Energy Security, General Secretary Jinping and the decisions and deployments of the Party Central Committee and the State Council, anchor the carbon peak and carbon neutral goals and tasks, and focus on renewable energy planning Policies, major project construction and energy and people’s livelihood guarantee, strive to improve governance capabilities and service levels, and actively promote the high-quality development of renewable energy. The installed scale of renewable energy has steadily expanded. As of the end of June 2021, China's installed renewable energy power generation capacity reached 971 million kilowatts. Among them, hydropower installed capacity is 378 million kilowatts (of which pumped storage is 32.14 million kilowatts), wind power installed capacity is 292 million kilowatts, photovoltaic power generation capacity is 268 million kilowatts, and biomass power generation capacity is 33.19 million kilowatts. Renewable energy power generation continues to grow. From January to June 2021, China's renewable energy power generation capacity will reach 1.06 trillion kWh. Among them, hydropower above designated size was 482.67 billion kwh, a year-on-year increase of 1.4%; wind power was 344.18 billion kwh, a year-on-year increase of about 44.6%; photovoltaic power generation was 157.64 billion kwh, a year-on-year increase of about 23.4%; biomass power generation was 77.95 billion kwh, a year-on-year increase About 26.6%. Renewable energy maintains a high level of utilization. From January to June in 2021, China’s major river basins have abandoned water power of approximately 5.364 billion kWh, and the utilization rate of water energy is approximately 98.43%, an increase of 0.07 percentage points from the same period last year; China’s curtailed wind power is approximately 12.64 billion kWh, with an average utilization rate of 96.4 %, an increase of 0.3 percentage points from the same period last year; China’s waste of electricity was 3.32 billion kWh, with an average utilization rate of 97.9%, an increase of 0.07 percentage points from the same period last year.

Hydropower construction and operation

From January to June 2021, China’s newly added hydropower grid-connected capacity is 7.69 million kilowatts. As of the end of June 2021, China’s installed hydropower capacity is approximately 378 million kilowatts, of which pumped storage is 32.14 million kilowatts. Positive progress has been made in the construction of major hydropower projects. The first batch of units of the Baihetan Hydropower Station was put into operation on June 28 safely and on time. The total installed capacity of the power station is 16 million kilowatts. It is the largest hydropower project under construction in the world and the most technically difficult hydropower project. After completion, it is the second largest hydropower station in the world. The capacity of 1 million kilowatts, the world's first, adopts China's self-designed and manufactured hydro-turbine generator sets that have been produced in China, filling the world's hydropower technology gap. As of July 28, 4 units have been put into operation for power generation; Wudongde All units of the hydropower station have been put into operation in June 2021; the Lianghekou Hydropower Station is expected to be put into operation in September 2021. From January to June 2021, China's hydropower generation capacity above designated size was 482.67 billion kWh, a year-on-year increase of 1.4%. The average utilization hours of hydropower in China was 1,496 hours, a year-on-year decrease of 33 hours. From January to June 2021, China’s major river basins have abandoned water power of approximately 5.364 billion kWh, a decrease of 417 million kWh compared with the same period in 2020, and the utilization rate of water energy is approximately 98.43%, an increase of 0.07 percentage points year-on-year. Water abandonment mainly occurred in Henan and Sichuan provinces. Henan Province’s abandoned water power was 3.372 billion kWh, mainly at the Xiaolangdi Water Control Project. The main reason was that the power plant was flooded in March and all units did not resume power generation until June. Hydropower is 1.160 billion kWh, a decrease of 2.517 billion kWh compared with the same period in 2020; the amount of water discarded in other provinces remains at a relatively low level.

In terms of the distribution of new installed capacity, the central-eastern and southern regions accounted for about 59%, and the "Three North" regions accounted for about 41%. The layout of wind power development has been further optimized. As of the end of June 2021, China's cumulative installed capacity of wind power reached 292 million kilowatts, of which onshore wind power has accumulated 281 million kilowatts and offshore wind power has accumulated 11.134 million kilowatts. From January to June 2021, China’s wind power generation capacity was 344.18 billion kWh, a year-on-year increase of 44.6%; the number of utilization hours was 1,212 hours. Among the provinces with higher utilization hours, Yunnan 1,769 hours, Mengxi 1,426 hours, and Sichuan 1,415 hours.
