The new policy supplements the variety of auxiliary services and defines the compensation mechanism and cost sharing principle
On December 27, 2021, Shandong energy storage demonstration project – national power investment Haiyang 101mwh / 202mwh energy storage power station was officially connected to the grid for trial operation, which responded to the policy calls of the national energy administration, such as the provisions on the management of power grid connection operation and the measures for the management of power auxiliary services. The main problems to be solved by the new policy are the following four points:
(1) The existing auxiliary service varieties are insufficient to meet the needs of system operation. Solution: add auxiliary service varieties such as moment of inertia, climbing, stable machine cutting and stable load cutting, promote the consumption of new energy, improve the reliability and power quality of power system, ensure energy security and promote green and low-carbon development.
(2) The power generation side bears the cost of system auxiliary services unilaterally, which can not bear a large number of system access to renewable energy. Solution: it is emphasized that “who provides, who profits; who benefits, who bears” Determine the compensation mode and allocation mechanism. The compensation mechanism of various types of power auxiliary services is defined. When determining the compensation standard in the fixed compensation mode, the factors such as power auxiliary service cost, performance and reasonable income should be comprehensively considered, and the compensation intensity should be determined according to the principle of “compensation cost and reasonable income”; The formation mechanism of market-oriented compensation should consider the principles of power auxiliary service cost, reasonable determination of price range and price formation through market-oriented competition. In terms of allocation, it emphasizes the power auxiliary services serving the overall operation of the power system. The compensation cost is shared by the grid connected entities such as power generation enterprises and market-oriented power users, and the non market-oriented power users are gradually included in the scope of compensation cost allocation. For the power auxiliary services that serve the grid connected entities at the specific generation side, the compensation cost shall be shared by the grid connected entities at the relevant generation side. For power auxiliary services serving specific power users, the compensation expenses shall be shared by relevant power users.
(3) With the increasing volume of electricity traded across provinces and regions, the inter provincial auxiliary service mechanism and cost sharing principle need to be improved. Solution: clarify the responsibilities, obligations, participation methods and compensation sharing principles of inter provincial and inter regional generator units participating in auxiliary services, and establish a sharing mechanism for user participation. Expand the interruptible load of users that can only be adjusted downward to “both up and down” Users can adjust the load, and users can bear the necessary auxiliary service costs or obtain corresponding economic compensation according to their contribution in combination with their own load characteristics, so as to improve the demand side regulation capacity through the market mechanism.
(4) New energy storage, electric vehicle charging network, etc. Shenzhen New Industries Biomedical Engineering Co.Ltd(300832) There is also an urgent need for market-oriented mechanisms to guide and promote development. Solution: this time, the scope of auxiliary service providers will be expanded from power plants to include new energy storage, self owned power plants, traditional high load industrial loads, industrial and commercial interruptible loads, electric vehicle charging networks, aggregators, virtual power plants and other subjects, so as to promote the excavation of flexible regulation capacity on both sides of supply and demand and accelerate the construction of new power systems.
The pressure on the cost bearing of the power generation side system is reduced, which is conducive to the accelerated expansion of China’s large-scale energy storage
The core dilemma of energy storage development lies in the lack of reasonable business model. This policy defines the participation mode and mechanism of energy storage in power assistance, and further straightens out its business development model. The new energy storage is included in the auxiliary service body, and the compensation mechanism and sharing mechanism are defined in terms of cost bearing. The compensation mechanism is a combination of fixed compensation and market-oriented compensation. In terms of allocation, it is clear that the compensation costs of power auxiliary services serving the generation side and the user side are borne by their respective subjects. We believe that this will reduce the pressure on the generation side to bear the system cost to a certain extent, and is conducive to the rapid improvement of the scale of the energy storage system on the generation side.

Risk tip: the policy implementation is less than expected and the market competition is intensified
