The new energy storage installed machine is competitive in the whole country, leading in Inner Mongolia.

Since 2024, China's new energy storage installed capacity has maintained rapid growth. According to the data of the National Energy Administration, by the end of 2024, the cumulative installed capacity of new energy storage projects completed and put into operation nationwide reached 73.76 million kilowatts/168 million kWh, about 20 times that of the end of the Thirteenth Five-Year Plan, and an increase of more than 130% compared with the end of 2023.

At the same time, in 2024, the development of energy storage in various places showed a competitive trend. The press conference of the National Energy Administration in the first quarter of 2025 announced the top five provinces and regions in the cumulative installed capacity of new energy storage in 2024, namely Inner Mongolia (10.23 million kilowatts/24.39 million kwh), Xinjiang (8.57 million kilowatts/28.71 million kwh), Shandong (7.17 million kilowatts/15.55 million kwh) and Jiangsu (5.62 million kilowatts/11.95 million kwh).

By the end of 2023, the top five provinces and regions in terms of 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) and Hunan (2.66 million kilowatts/5.31 million kilowatt hours). Based on the data of the National Energy Administration, in 2024, the installed capacity of new energy storage in Inner Mongolia increased by 6.69 million kilowatts, in Xinjiang by 5.48 million kilowatts, and in Shandong by 3.19 million kilowatts. The installed capacity of the three provinces and regions entered the top five in China for two consecutive years.

Policies such as low installed base, short construction period and new energy allocation and storage are the main reasons to promote the short-term rapid growth of new energy storage scale in various places. The Special Action Plan for the Development of New Energy Storage in Inner Mongolia Autonomous Region from 2024 to 2025 proposes that the Energy Bureau of Inner Mongolia Autonomous Region should coordinate the development planning, layout and project construction of new energy storage in the whole region, adhere to the principle of centralized concentration and intensive planning, and make overall plans according to the mode of "centralized construction, centralized storage and unified dispatching". In 2024, 10 million kilowatts of new energy storage will be started, and 6.5 million kilowatts/29 million kilowatt hours will be completed and put into operation, and new energy storage will be started again in 2025.

In 2024, Jiangsu became a "dark horse" province to develop new energy storage, and its installed capacity of new energy storage increased by more than 400%. Different from Inner Mongolia, Shandong and Xinjiang, Jiangsu launched new energy storage in 2024 mainly to ensure peak power supply and power grid side energy storage. In March, 2024, the Development and Reform Commission of Jiangsu Province issued the Notice on Further Accelerating the Summit Work of Grid-connected New Energy Storage Projects, which made it clear that after many times of coordination and repeated combing, there were 41 grid-connected new energy storage projects in the province that had accepted the regulations, and they voluntarily promised to be connected to the grid before July 15th, 2024, with a total project capacity of about 4 million kilowatts. The Notice of Jiangsu Provincial Development and Reform Commission in September, 2024 on Issuing the Planning Scale of a Batch of New Energy Storage Projects on Power Grid Side requires that the scale of new energy storage projects on power grid side to be implemented in advance is about 1 million kilowatts, and strive to be put into operation in parallel before the end of 2024 and before June, 2025.

While local policies stimulate the growth of new energy storage installed capacity, they also make the national "qualifying" competition more intense. In mid-2023, the installed capacity of new energy storage in Hunan was 2.64 million kilowatts, ranking second in the country. In 2024, the installed capacity of new energy storage in Hunan increased by less than 300,000 kilowatts, reaching 2.86 million kilowatts, ranking 10th in China. In 2024, Gansu also fell out of the top five list. In recent years, Guangdong has proposed to vigorously develop new energy storage industry. In 2024, the installed capacity of new energy storage in Guangdong reached 3.5 million kilowatts, and the growth potential of new energy storage installed capacity in Zhejiang, Hebei and Guangxi is also great. There are still many points to watch in the follow-up ranking.
