Policy Interpretation: Establish a new energy storage project management standard to promote the safe and orderly development of the energy storage industry

China Energy Storage Network News: On June 22, 2021, the General Department of the National Energy Administration issued the "New Energy Storage Project Management Specification (Interim) (Draft for Comment)" (hereinafter referred to as the "Specification"). At present, it is the first year of the "14th Five-Year Plan". The new energy storage is facing a critical period of transition from the initial stage of commercialization to large-scale development. There is an urgent need for standardized management. The introduction of the "Regulations" can be described as the right time. The Code puts forward clear and specific requirements for the planning and guidance, filing and construction, grid-connected operation, monitoring and supervision of new energy storage projects, which is of great significance for standardizing the management of new energy storage projects and promoting the orderly, safe and healthy development of new energy storage projects.

"Specification" is based on the objective actual situation faced by my country's new energy storage industry, adheres to problem-oriented and goal-oriented, pays attention to actual results, and faces the difficulties and pain points of the development of the new energy storage industry. The main content includes the following aspects:

First, adhere to the principle of safety first, tolerance and prudence, and solve the contradiction between safety and development. In recent years, there have been many safety accidents of electrochemical energy storage power stations at home and abroad. Among them, the "4.16" safety accident of Beijing energy storage power station caused many casualties, which sounded the safety alarm for the entire energy storage industry and must be highly concerned. The Code adheres to the principle of safety first, tolerance and prudence. On the one hand, it requires to keep the bottom line of safety and put the safety of people's lives and property in the first place; on the other hand, the new energy storage industry is an emerging industry. It is not perfect in technology, standards, applications and other aspects. It is necessary to adopt an inclusive and prudent attitude and adopt a scientific and standardized management system to ensure the safety of new energy storage projects, and can not be used as a reason to hinder the construction of new energy storage projects and the development and progress of technology.

2 is to put forward the new energy storage project life cycle safety management requirements, to solve the problem of unclear responsibility . The safety problems of energy storage projects are not only related to the R & D and manufacturing level of energy storage systems, but also related to power station design, construction and installation, commissioning, acceptance, grid-connected operation, operation and maintenance and other links. The defects and negligence of any link may lead to major safety accidents. The Code puts forward clear safety management requirements for the responsible subjects of the new energy storage project at each stage: in the project filing stage, the relevant units of the new energy storage project shall, in accordance with the requirements of relevant laws, regulations and technical specifications, strictly perform the management procedures of project safety, fire protection and environmental protection, and implement the safety responsibility; Before the commissioning of the new energy storage project, the relevant procedures shall be completed in accordance with the relevant national regulations on quality, environment and fire protection; energy authorities at all levels should strengthen communication and coordination with relevant departments of the local people's government, establish a new type of energy storage project safety management and fire rescue linkage mechanism; project units should implement the work policy of "prevention first, combination of prevention and elimination", implement the main responsibility of fire safety during the operation of the project, and do a good job in the safe operation and management of the project.

3 is to propose that in principle, no new large-scale power battery echelon energy storage projects should be built to avoid high safety risks. decommissioned power battery can make full use of its residual value through echelon utilization before resource recycling. However, decommissioned power battery also faces problems such as uneven quality, short cycle life, high safety risk of thermal runaway, etc. Compared with energy storage projects using new batteries, energy storage projects using echelon utilization power batteries face higher safety risks. Therefore, at this stage, under the condition that the relevant management means and technical conditions of decommissioned power batteries are not yet mature, the safety risk of large-scale power battery echelon utilization energy storage projects is very high and difficult to effectively control, and it is an effective measure to avoid safety risks not to build new large-scale power battery echelon utilization energy storage projects. "Code" requirements: in the battery consistency management technology to achieve a key breakthrough, power battery performance monitoring and evaluation system is sound, in principle, no new large-scale power battery echelon use of energy storage projects. The power battery ladder utilization energy storage project that has been completed and put into operation should regularly evaluate the battery performance, strengthen monitoring and strengthen supervision.

Four is to focus on top-level design and planning guidance to solve the problem of disorderly development. under the goal of "double carbon", the new energy storage industry will usher in historic development opportunities, but it is also faced with the problem of disorderly development, such as unbalanced regional development, overheated investment in some fields, uncoordinated upstream and downstream development, and overcapacity of some products. It is urgent to guide the healthy and healthy development of the industry through top-level design and planning, so as to avoid mass action and disorderly development. The "Code" clarifies that the energy authority of the State Council is responsible for preparing the national new energy storage development plan; the provincial energy authority is in accordance with the national new energy storage development plan, in accordance with the "government guidance, enterprise participation, innovation leadership, demonstration first, market leadership, reform promotion, overall planning, coordinated development" principle, study the key tasks of the region, and guide the development of new energy storage in the region; energy authorities at all levels to strengthen the construction of new energy storage project monitoring and management system, according to the region's new energy storage project filing, construction, operation, market trading situation, research and regularly announced the new energy storage development scale, construction layout, scheduling operation, etc., to guide the new energy storage project scientific and reasonable investment and construction.

5 is to emphasize regulations, qualifications and standards to solve the problem of unfounded and fairness. At this stage, my country's new energy storage-related regulations and standards are not perfect, and testing and certification are not sufficient, resulting in the quality of new energy storage products and projects on the market, and the qualification requirements of relevant participants are not clear. Low barriers and other issues. The "Code" has repeatedly emphasized that in all aspects of the new energy storage project, it must comply with relevant regulations and standards, and relevant entities should meet the corresponding qualification requirements. Relevant requirements include: new energy storage projects shall be put on record management in accordance with relevant laws and regulations; after completing the filing, construction shall be started in time after other relevant construction procedures required by laws and regulations; the construction of new energy storage projects shall meet the requirements of relevant management regulations and standards and specifications, and the units undertaking project design, consultation, construction and supervision shall have the corresponding qualifications stipulated by the state; the main equipment of new energy storage projects shall meet the requirements of relevant standards and specifications, through the testing and certification of the corresponding qualification institutions, the network-related equipment should meet the relevant technical requirements for the safe operation of the power grid; the relevant units of the new energy storage project should strictly implement the project safety, fire protection, environmental protection and other management procedures in accordance with the requirements of relevant laws, regulations and technical specifications, and implement Safety responsibility; before the new energy storage project is connected to the grid and commissioned, relevant procedures should be completed in accordance with the relevant national quality, environmental and fire protection regulations; power grid enterprises shall, in accordance with the requirements of relevant standards and specifications, clarify the process of grid-connected commissioning and acceptance, and actively cooperate with the grid-connected commissioning and acceptance of new energy storage projects; power grid enterprises shall, in accordance with the requirements of laws, regulations and technical specifications, take systematic measures to optimize the dispatching operation mechanism, give priority to scientific calls, ensure the utilization rate of new energy storage, and give full play to the role of new energy storage systems.

6 is to take compulsory retirement measures to solve the problem of extended service and sick work. With the increase of the operating life of the new energy storage project, the aging of the equipment and the attenuation of the battery performance will become more and more serious, and the probability of quality problems and safety accidents will increase. Therefore, it is necessary to carry out project operation status monitoring and safety status assessment, establish the project retirement mechanism, and avoid overdue service and work with diseases. The Code requires the project unit to do a good job in monitoring the operating status of the new energy storage project, monitor the operating conditions of the energy storage system in real time, and organize the demonstration, evaluation and rectification work in a timely manner when the project reaches the design life or the safe operating conditions do not meet the relevant technical requirements. If the relevant requirements are still not met after rectification, the project unit shall take timely project decommissioning measures and report to the original filing authority and other relevant units in a timely manner.

In general, the "Specifications" for the first time clarified the responsibilities and specific requirements of all parties involved in the construction and operation of new energy storage projects, which can effectively avoid problems such as unclear powers and responsibilities and disorderly development. Improve the standardized management level of new energy storage, lay the foundation for the large-scale construction of new energy storage, and will surely promote the rapid development of new energy storage.
