[Two departments: Encourage large new energy bases equipped with new energy storage to participate as a whole in the mid- and long-term cross-provincial market] On November 13, the National Development and Reform Commission and the National Energy Administration issued the "New Energy Storage Implementation Plan for the 15th Five-Year Plan". It is proposed to further promote new energy storage to participate in the electric energy market. Promote the fair participation of new energy storage in the mid- to long-term and spot markets, and encourage new energy storage to rationally arrange operation plans through market price signals. Encourage large new energy bases equipped with new energy storage to participate as a whole in the mid- and long-term markets across provinces and regions. Encourage various localities to promote the construction of energy storage as an independent operating entity to participate in the power market according to local conditions. Study and improve the setting of price limits for the mid- to long-term market and spot market of electricity, and connect various markets to create space for the development of new energy storage. Accelerate the construction of ancillary service market based on actual conditions. In areas where the spot market operates continuously, the establishment of frequency modulation auxiliary service markets should be accelerated, and auxiliary service markets such as backup, ramping, and rotational inertia should be researched and explored to fully reflect the value of new energy storage regulation resources. Support new energy storage to participate in the ancillary service market in various forms such as independent power stations, energy storage aggregators, and virtual power plants. Improve the compensation and allocation mechanism for power auxiliary services.
