According to the tracking of the energy storage and power market, a number of independent energy storage systems have been launched in Shaoxing, Ningbo and other places in Zhejiang recently. At present, Zhejiang has formulated a relatively complete energy storage policy system, and has launched a demonstration project with a scale of over 1.4GW in 2022. In addition, municipal governments across Zhejiang have also begun to formulate plans for energy storage projects and industrial implementation. This seems to indicate that Zhejiang energy storage will enter a stage of rapid development.

In fact, Zhejiang is not a traditional energy storage hotspot market. Judging from the existing projects in operation, Zhejiang Province is dominated by grid-side energy storage projects. The recent increase in demand for new energy distribution and storage and the development of independent energy storage power stations may bring a new pattern to energy storage applications in Zhejiang Province. Combined with Zhejiang's energy storage scale of about 100MW at the end of 2021 and its cumulative installed capacity target of 3GW in 2025, Zhejiang's new energy storage is expected to achieve nearly 30-fold growth during the "14th Five-Year Plan" period.

Zhejiang Energy Storage Related Policies

According to the tracking of the energy storage and power market, from the second half of 2021 to the present, Zhejiang has released a number of documents related to energy storage development, covering energy storage demonstration project planning, energy storage industry development planning, power auxiliary service market and other aspects. At the same time, the application of energy storage is also emphasized in the development plan of renewable energy. In addition, some cities/counties in Zhejiang Province have also launched energy storage industry policies combined with new energy development according to their own industrial development characteristics, actively seizing the energy storage track and seeking industrial development.

Zhejiang Province Energy Storage Industry Policy

At present, Zhejiang has formed a relatively complete energy storage policy system. In terms of development goals and demonstration applications, Zhejiang has undergone several adjustments, and finally formed the development goal of building 3GW of energy storage during the "14th Five-Year Plan" period.

In terms of energy storage peak shaving compensation, Zhejiang is one of the first regions in China to propose a capacity compensation policy for peak shaving energy storage power stations. Providing a three-year capacity compensation mechanism for energy storage will provide certain support for the early benefits of energy storage power stations ( The compensation standard is declining year by year, at 200, 180, and 170 yuan/kW·year respectively).

Local counties/cities represented by Haining City have proposed a package of energy storage industry development policies based on industrial planning and new energy development strategies, such as:

In March 2021, the "Guiding Opinions on Promoting the Coordinated Development of Source, Grid, Load and Storage and Promoting the Efficient Utilization of Clean Energy" was issued, proposing that in principle, new energy projects should allocate energy storage at 10% of the installed capacity.

In November 2021, the "Implementation Opinions on Accelerating the Development of New Energy Storage" was issued, encouraging newly built new energy projects to allocate energy storage at 10% to 20%, and the energy storage time should not be less than 2 hours.

In May 2022, the "Haining "14th Five-Year Plan" New Energy Storage Layout" and "Haining Energy Storage Industry Planning" were released. It is planned that by 2025, the total output value of the energy storage industry in Haining will exceed 20 billion yuan. By 2030, the energy storage industry The total output value reaches 50 billion to 100 billion yuan. Editor / Xu Shengpeng
