By the end of 2023, the country had completed and put into operation a total installed capacity of 31.39 million kilowatts/66.87 million kilowatt-hours, with an average energy storage time of 2.1 hours.
The Zhitong Finance App learned that the official website of the National Energy Administration on January 25 reported that the National Energy Administration held a press conference to introduce the development of China's new energy storage in 2023, the construction of a unified national electricity market system, the background of the establishment of the International Clean Energy Day, and China's contribution to global clean energy development, and answer questions from reporters. Bian Guangqi, deputy director of the Department of Energy Conservation and Technology Equipment, said that new energy storage systems are developing rapidly, and more than 30 million kilowatts of installed capacity have already been put into operation. By the end of 2023, new energy storage projects had been completed and put into operation nationwide with a cumulative installed capacity of 31.39 million kilowatts/66.87 million kilowatt-hours, with an average energy storage time of 2.1 hours. In 2023, the installed capacity was about 22.6 million kilowatts/48.7 million kilowatt-hours, an increase of more than 260% over the end of 2022, and nearly 10 times the installed capacity at the end of the 13th Five-Year Plan.

Bian Guangqi: By the end of 2023, the country had built and put into operation a total installed capacity of 31.39 million kilowatts/66.87 million kilowatt-hours
The National Energy Administration held a press conference to introduce China's new energy storage development in 2023, the construction of a unified national electricity market system, the background of the establishment of the International Clean Energy Day, and China's contribution to global clean energy development, and answer questions from reporters.
[Bian Guangqi, Deputy Director of the Department of Energy Conservation and Technology Equipment] Good morning to all reporters and friends. Next, I will give a brief introduction to the development of new energy storage in China in 2023. In 2023, the National Energy Administration will earnestly implement the new “Four Revolutions, One Cooperation” energy security strategy, anchor the “double carbon” goal, and achieve remarkable results in promoting diversified and high-quality development of new energy storage. New energy storage is increasingly becoming a key technology for building new energy systems and new power systems in China, an important direction for cultivating emerging industries, and an important gripper for promoting the green and low-carbon transformation of energy production and consumption.
New types of energy storage are developing rapidly, and more than 30 million kilowatts of installed capacity have already been put into operation. By the end of 2023, new energy storage projects had been completed and put into operation nationwide with a cumulative installed capacity of 31.39 million kilowatts/66.87 million kilowatt-hours, with an average energy storage time of 2.1 hours. In 2023, the installed capacity was about 22.6 million kilowatts/48.7 million kilowatt-hours, an increase of more than 260% over the end of 2022, and nearly 10 times the installed capacity at the end of the 13th Five-Year Plan. Judging from the scale of investment, since the “14th Five-Year Plan”, the addition of new energy storage installations has directly promoted economic investment exceeding 100 billion yuan, driving further expansion upstream and downstream of the industrial chain, and becoming a “new driving force” for China's economic development.
The development of new types of energy storage has been accelerated in many places, and the installed capacity in 11 provinces (regions) has exceeded one million kilowatts. By the end of 2023, the top 5 provinces and regions with a cumulative installed capacity of new energy storage were: Shandong 3.98 million kilowatts/8.02 million kilowatt-hours, Inner Mongolia, 3.54 million kilowatts/7.1 million kilowatt-hours, Xinjiang 3.09 million kilowatts/9.52 million kilowatt-hours, Gansu 2.93 million kilowatts/6.73 million kilowatt-hours, Hunan, 2.66 million kilowatts/5.31 million kilowatt-hours. The installed capacity of Ningxia, Guizhou, Guangdong, Hubei, Anhui and Guangxi exceeded 1 million kilowatt-hours kilowatts. Looking at subregions, new energy storage is developing rapidly in North China and Northwest China, accounting for more than 50% of the country's installed capacity, of which the northwest region accounts for 29% and North China accounts for 27%.
New energy storage technologies continue to emerge, and the technical route is “in full bloom”. Lithium-ion battery energy storage still dominates. Technologies such as compressed air energy storage, liquid flow battery energy storage, and flywheel energy storage have developed rapidly. Since 2023, construction of several 300 MW compressed air energy storage projects, 100 MW liquid flow battery energy storage projects, and megawatt flywheel energy storage projects has started. 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. By the end of 2023, lithium-ion batteries had been put into operation accounting for 97.4% of energy storage, lead-carbon batteries accounting for 0.5% of energy storage, compressed air accounting for 0.5% of energy storage, liquid flow batteries accounting for 0.4% of energy storage, and 1.2% of other new energy storage technologies.
The new energy storage is effective in multiple application scenarios and strongly supports the construction of new power systems. The first is to promote the development and consumption of new energy sources. By the end of 2023, the installed capacity of new energy distribution and energy storage will be about 12.36 million kilowatts, mainly distributed in provinces and regions where new energy is developing rapidly, such as Inner Mongolia, Xinjiang, and Gansu. The second is to raise the level of safe and stable operation of the system. The installed scale of independent energy storage and shared energy storage reached 15.39 million kilowatts, accounting for an upward trend. It is mainly distributed in provinces and regions with high demand for system regulation such as Shandong, Hunan, and Ningxia. Third, service users use energy flexibly and efficiently, and energy storage for industrial and commercial users in Guangdong, Zhejiang and other provinces is developing rapidly.
Recently, the National Energy Administration organized and carried out pilot demonstration work for new energy storage, and selected a number of new energy storage projects with advanced technical indicators and rich application scenarios. It will use this as a starting point to continue to promote the high-quality development of new energy storage and strive to promote the progress of energy science and technology. Thank you.
