China News Service, January 25 (Xinhua) The National Energy Administration held a press conference on the 25th to introduce the development of new energy storage in my country in 2023, the construction of a national unified power market system, the background of the establishment of International Clean Energy Day, and my country's contribution to the development of global clean energy. .
At the meeting, Bian Guangqi, deputy director of the Department of Energy Conservation and Science and Technology Equipment of the National Energy Administration, introduced the development of new energy storage in my country in 2023.
He said that in 2023, new energy storage will develop rapidly, with more than 30 million kilowatts of installed capacity in operation.
As of the end of 2023, the cumulative installed capacity of new energy storage projects that have been completed and put into operation across the country has reached 31.39 million kilowatts/66.87 million kilowatt hours, with an average energy storage time of 2.1 hours.
Bian Guangqi introduced that new energy storage has developed rapidly, with more than 30 million kilowatts of installed capacity in operation.
As of the end of 2023, the cumulative installed capacity of new energy storage projects that have been completed and put into operation across the country has reached 31.39 million kilowatts/66.87 million kilowatt hours, with an average energy storage time of 2.1 hours.
The newly installed capacity in 2023 will be approximately 22.6 million kilowatts/48.7 million kilowatt-hours, an increase of more than 260% from the end of 2022, and nearly 10 times the installed capacity at the end of the 13th Five-Year Plan.
From the perspective of investment scale, since the "14th Five-Year Plan", new new energy storage installed capacity has directly promoted economic investment of more than 100 billion yuan, driving the further expansion of the upstream and downstream of the industrial chain and becoming a "new driving force" for my country's economic development.
Many places have accelerated the development of new energy storage, with 11 provinces (regions) having installed capacity exceeding one million kilowatts.
As of the end of 2023, the top five provinces and regions with cumulative installed capacity of new energy storage are: Shandong with 3.98 million kilowatts/8.02 million kilowatt-hours, Inner Mongolia with 3.54 million kilowatts/7.1 million kilowatt-hours, Xinjiang with 3.09 million kilowatts/9.52 million kilowatt-hours, Gansu 2.93 million kilowatts/6.73 million kilowatts, Hunan 2.66 million kilowatts/5.31 million kilowatts, the installed capacity exceeds 2 million kilowatts, and the installed capacity of 6 provinces and regions including Ningxia, Guizhou, Guangdong, Hubei, Anhui, and Guangxi exceeds 1 million kilowatts.
In terms of regions, new energy storage has developed rapidly in North and Northwest China, accounting for more than 50% of the country's installed capacity, of which Northwest China accounts for 29% and North China accounts for 27%.
New energy storage technologies are constantly emerging, and the technical roadmap is “letting a hundred flowers bloom”.
Lithium-ion battery energy storage still occupies an absolute dominant position, and technologies such as compressed air energy storage, flow battery energy storage, and flywheel energy storage are developing rapidly. Since 2023, multiple 300-megawatt-level compressed air energy storage projects, 100-megawatt-level compressed air energy storage projects, and other technologies have developed rapidly. The construction of flow battery energy storage projects and megawatt-level flywheel energy storage projects has begun, and new technologies such as gravity energy storage, liquid air energy storage, and carbon dioxide energy storage have been implemented, showing an overall diversified development trend.
As of the end of 2023, 97.4% of lithium-ion battery energy storage has been put into operation, 0.5% of lead-carbon battery energy storage, 0.5% of compressed air energy storage, 0.4% of flow battery energy storage, and other new energy storage Technology accounts for 1.2%.
New energy storage has multiple application scenarios and effectively supports the construction of new power systems.
The first is to promote the development and consumption of new energy. As of the end of 2023, the installed capacity of new energy energy storage will be approximately 12.36 million kilowatts, mainly distributed in provinces and regions where new energy development is rapid, such as Inner Mongolia, Xinjiang, and Gansu.
The second is to improve the level of safe and stable operation of the system. The installed capacity of independent energy storage and shared energy storage has reached 15.39 million kilowatts, and the proportion is on the rise. It is mainly distributed in Shandong, Hunan, Ningxia and other provinces with greater system adjustment needs.
The third is to serve users with flexible and efficient energy use. Energy storage for industrial and commercial users in Guangdong, Zhejiang and other provinces has developed rapidly.
