In order to further clear the new Energy Storage market orientation, set up perfect market mechanism, price mechanism and operational mechanism, enhance the level of new energy storage using and guide the healthy development of industry, the National Development and Reform Commission, the state energy bureau recently issued by the "about further promoting new energy storage in electric power market and operation notice (hereinafter referred to as the" notice "), It proposes to accelerate the participation of independent energy storage in the mid - and long-term market and spot market. If an independent energy storage station transmits electricity to the power grid, its corresponding charging power shall not bear the electricity price of transmission and distribution, governmental funds and additional charges.
According to the introduction, the new energy storage has the advantages of quick response, flexible configuration and short construction period. It can play a variety of roles in power operation, such as peak, peak, frequency modulation, climbing, black start and so on, and is an important part of the construction of a new power system. It is necessary to establish and improve the market mechanism suitable for energy storage participation, encourage new energy storage to participate in the power market independently, adhere to the market-oriented pricing, continue to improve the dispatching operation mechanism, give full play to the advantages of energy storage technology, improve the overall utilization level of energy storage, ensure reasonable returns of energy storage, and promote the healthy development of the industry.
As required, new energy storage can participate in the power market as independent energy storage. New energy storage projects with legal personality can be converted to independent energy storage and participate in the power market as an independent subject if they have the technical conditions of independent metering and control, access to the dispatching automation system can be monitored and dispatched by the power grid, and meet the requirements of relevant standards and specifications and power market operation institutions. Encourage new energy storage projects existing in the form of auxiliary construction. When the same technical conditions and safety standards are met through technical transformation, they can choose to become independent energy storage projects. According to the relevant requirements of the Guiding Opinions of the National Development and Reform Commission and the National Energy Administration on Promoting the Integration of Charge and Storage of Power Source Network and the Development of Multi-energy Complementarity, the energy storage of the multi-energy complementarity integration project involving scenery, water and fire storage will not be converted to independent energy storage temporarily in principle.
The Circular encourages the installation of new energy storage and the joint participation of their power sources in the electricity market. New energy storage projects existing in the form of allocation are encouraged to participate in the power market in accordance with existing relevant rules by combining with other types of power supply as a whole, provided that the transformation of metering and control systems within the station is completed and relevant technical requirements are met. According to the actual situation of power supply liberalization in the market, new energy stations and allocated energy storage are encouraged to participate in the market jointly, so as to use energy storage to improve the performance of new energy grid and ensure the efficient consumption and utilization of new energy. With the gradual maturity of market construction, it is encouraged to explore a market model in which the same energy storage entity can participate in both independent and joint capacity.
It is worth noting that the circular calls for accelerating the participation of independent energy storage in the power market in conjunction with peak regulation of the grid. Accelerate the participation of independent energy storage in the medium - and long-term market and spot market. In view of the relatively small energy storage capacity at the present stage, independent energy storage is encouraged to sign peak and trough market contracts to play the role of peak shifting and valley filling and peak power generation. If an independent energy storage station transmits electricity to the power grid, its corresponding charging power shall not bear the electricity price of transmission and distribution, governmental funds and additional charges.
To give full play to the advantages of independent energy storage technology to provide auxiliary services. Independent energy storage is encouraged to provide auxiliary services such as active power balancing service, reactive power balancing service and accident emergency and recovery service, as well as rapid active power response service in case of power grid accident, in accordance with auxiliary service market rules or auxiliary service management rules. Auxiliary service fees shall be reasonably shared by the grid-connected subjects and power users on the relevant generating side according to the relevant provisions of the Administrative Measures for Electric Auxiliary Services and the principle of "who provides, who gains, who benefits and who bears".
In terms of energy storage scheduling operation mechanism, the Circular requires that energy storage scheduling operation be optimized mainly in a market-oriented way. For the allocated energy storage that is not involved in the market, especially the allocated energy storage of new energy, the power dispatching institution should establish a scientific dispatching mechanism, and the project owner should strengthen the operation and maintenance of the energy storage facility system to ensure the safe and stable operation of the energy storage system. For energy storage of coal-fired power generation and other types of power supply, refer to the above requirements to further improve energy storage utilization level.
At the same time, it further supports the development of user-side energy storage. According to the actual situation of power supply and demand, the peak-valley price difference should be appropriately widened to create space for the development of user-side energy storage. According to the actual situation of each region, it is encouraged to further increase the upper and lower prices of medium and long term power market and spot market, guide users to proactively configure new energy storage, and increase the revenue channels of energy storage on the user side. Users are encouraged to use energy storage technology to reduce their own peak power demand and reduce the capacity expansion investment of access power system.
In addition, the power grid side energy storage price mechanism is established. Local governments should strengthen scientific planning and effective supervision of power grid side energy storage, and encourage power grid side to build energy storage facilities at key nodes according to the operation needs of the power system. Research on the establishment of power grid side independent energy storage power station capacity price mechanism, gradually promote the power station to participate in the power market; Explore how to include the cost and income of power grid alternative energy storage facilities into the recovery of power transmission and distribution price.
