On March 28, the National Development and Reform Commission (NDRC) officially issued the "Method of Guaranteed Purchase of Renewable Power Generation" (hereinafter referred to as "Method") in order to strengthen the handling of guaranteed purchase of renewable power generation. The implementation of the method is of great significance to the completion of the policy on the proportion of non-fossil power expenditure in China, the promotion of the structural reform on the supply side of power category, and the promotion of the innovation of power production and power expenditure. Together, the Method is also an important action to support and cooperate with the transformation of China's electric power industry. It is a concrete manifestation of the policy and mission of implementing the renewable power generation category in the transformation of electric power system. At that time, the situation of grid connection of renewable power generation was grim, and the scene of "abandoning wind and light" was prominent. The "Method" was like a "shot in the arm", providing new impetus for the reduction, abandonment and increase of renewable power generation.
According to the spirit of the document, "guaranteed purchases" and "shopping malls" will support the grid-connected consumption of renewable power. Look to the condition at present stage, "assure sex buy" still be a center, bazaar buys and sells make up for. And the guarantee sex of project of power generation of project of renewable power connect a network buys annual go on line electricity quantity is the basis of guarantee sex buy annual use hour number and installed capacity conclude, thus guarantee sex buy annual use hour number became crucial target. "Method" rules of renewable power generation limited area, the power under the State Council shall be responsible for parts with the competent economic operation will be given to transport based on the grid and system, in accordance with all kinds of electricity price benchmarking cover area, refer to allow capital plus reasonable profits, to the various renewable power grid-connected power generation project guarantee bought years use hours, according to the regional actual situation in season to adjust. Also that said, the use of the number of hours for approval, must fit physical bondage (given to transport grid and system), the economic ties (asset price reasonable income), and geographical constraints, on the basis of regional industrial characteristics and renewable power generation), complex thinking factors, in the face of changing environment, how to ensure that the goal of scientific rationality and the accuracy is very important. "Method", points out that buying refers to the renewable power generation full guarantee sex (including electric power dispatching institution) according to the national grid company decided that the benchmark price of the number of hours and ensure to buy used, combined with the market competition mechanism, after execution priority rule of power generation, on the premise of ensure the safety of power supply, buy scheme in full scale in renewable power generation project of electricity on the Internet. Meanwhile, the "method" divided the annual generating capacity of renewable power grid-connected power generation projects into guaranteed purchase power some and shopping mall purchase power some. In accordance with the rules of documents, guaranteed purchase of electricity is made in some cases by organizing the annual power generation plan in priority and signing the preferential power generation contract (miscellaneous contract or contract for difference) with the power grid company to guarantee the purchase in full according to the benchmark feed-in tariff. Beyond the guaranteed purchasing power scale, renewable power generation companies are encouraged to give full play to the advantages of low marginal cost of renewable power power, and complete priority generation and promote multiple full generation by participating in market competition. In addition, the application scale of the document mainly includes wind power generation, solar power generation, biomass power generation, geothermal power generation, Marine power generation and other non-water renewable power. The hydropower generation will be based on the benchmark electricity price determined by the state (or the approved power station electricity price) and the average number of designed hours of use. Through the implementation of long-term electricity purchase and sale agreement, the priority organization of annual power generation plan and participation in spot market trading and other forms, the implementation of the priority power generation guidelines and full guaranteed purchase. Biomass energy, geothermal energy, ocean power generation and distributed photovoltaic power generation projects will not participate in the market competition for the time being, and the online power will be fully purchased by the grid company.
Notably, the Method also clarifies the risk commitment mechanisms and the scale of responsibilities of different entities. This is very important with regard to the standard China renewable power grid generation, correcting the non-standard operating forms and market practices in some areas. The main body of this category mainly includes relevant parts of the government, renewable power generation companies, non-renewable power generation companies, power grid companies and users, etc.
The government concerned part undertook two crucial duty in the meantime; One is to check and ratify the key goal of buying the number of hours of use per year and draw up a plan for generating electricity. The second is to fulfill the responsibility of the supervision of the guaranteed purchase of renewable power generation, to supervise the signing and implementation of the contract, and to carry out harmony on the issues such as power generation limit and reimbursement of Shared expenses. Together, the government supervision part has the responsibility to carry out investigations and regularly release to the public about the situation of constraining power generation and non-compliance. To sum up, the government is to "make plans, regulate harmoniously and protect fairness".
