Renewable energy construction to speed up green development to add impetus

General Secretary Xi Jinping pointed out that it is necessary to increase efforts to plan and build a new energy supply and consumption system based on large solar power bases, supported by clean, efficient and advanced energy-saving coal power around them, and supported by stable, safe and reliable UHV transmission and transformation lines.

Construction of power transmission channels to help the "development" of new energy.

At present, the world's highest altitude UHV direct current transmission project - the Jinsha River upstream to Hubei ±800 kV UHV direct current transmission project is busy, after completion, it can transport nearly 40 billion KWH of clean electric energy from the Sichuan-Tibet Plateau to central China every year.

"The Sichuan-Tibet Plateau is rich in hydropower and new energy resources with huge reserves. In the next 20 years, large hydropower bases such as the Jinsha River and Lancang River and large-scale photovoltaic bases around them will be developed and built one after another, with a total installed capacity of more than 100 million kilowatts." State Grid Hubei electric power deputy general manager Zhou Xinfeng introduced. As the first UHV DC project to enter the hinterland of the Sichuan-Tibet Plateau, the Jinshang-Hubei project can replace more than 17 million tons of coal every year, reduce about 34 million tons of carbon dioxide emissions, and will significantly increase the proportion of green electricity in central China.

Sichuan-chongqing 1000 kV UHV AC project site equipment roar, after the completion of the project, China's southwest grid main grid voltage level will be raised from 500 kV to 1000 kV, can transport more than 35 billion KWH of clean energy per year; Zhumadian - Wuhan 1000 kV UHV AC project is steadily advancing, which will help the large-scale transmission of clean energy in the west and north to meet the rapid growth of electricity demand in Central China... The construction of transmission channels has been accelerated, effectively improving the consumption level of renewable energy power.

Promote the construction of energy storage and promote the "good use" of new energy.

Nanning, Guangxi, the "14th Five-Year Plan" period in South China's first pumped storage power station to step up construction. "At present, the excavation of the second floor of the underground plant has been completed. It is expected that the excavation and support of the plant will be completed by the end of this year, and the installation of mechanical and electrical equipment will begin." Southern network energy storage company engineering construction management branch engineering department manager Liu Cao said.

In 2022, the construction of pumped storage capacity in China will accelerate significantly. The country newly approved 48 pumped storage projects, installed capacity of 68.9 million kilowatts, more than the "13th Five-Year" period of all approved scale, the year of new production of 8.8 million kilowatts, a record high. This year, the State Grid plans to start construction of five more pumped storage power stations and put four into operation. China Southern Power Grid will continue to accelerate the construction of four pumped storage power stations in Nanning, Meizhou Phase II, Zhaoqing Langjiang and Huizhou Zhongdong.

The growth of new energy storage installations such as lithium-ion battery energy storage, compressed air energy storage, and liquid flow battery energy storage continues to accelerate. By the end of 2022, the installed capacity of new energy storage projects in China had reached 8.7 million kilowatts, an increase of more than 110% over the end of 2021. The relevant person in charge of the National Energy Administration introduced that at present and in the next period, it will speed up the peaking capacity construction of pumped storage, peak gas power, new energy storage and other power systems, and vigorously improve the flexibility of residential and industrial and commercial power load, providing strong support for the development of wind power and photovoltaic.

Low-carbon energy development concerns the future of mankind. China's renewable energy development is in a promising period of strategic opportunities, in-depth implementation of the new strategy of energy security, unswervingly promote the large-scale, high-proportion, market-oriented, high-quality development of renewable energy, the vivid picture of a beautiful China is slowly spreading.
