Development and Reform Energy [2017] No. 1701

To the Development and Reform Commissions and Energy Bureaus of all provinces, autonomous regions, municipalities directly under the Central Government, and cities with independent planning status, and the Xinjiang Production and Construction Corps, the State Grid Corporation of China, and the China Southern Power Grid Corporation:

Energy storage is an important component and key supporting technology of smart grids, energy systems with a high proportion of renewable energy, and "Internet +" smart energy (hereinafter referred to as energy Internet). Energy storage can provide peak load regulation, frequency regulation, standby, black start, demand response support and other services for grid operation, and is an important means to improve the flexibility, economy and safety of traditional power systems; energy storage can significantly improve the absorption level of renewable energy such as wind and light, support distributed power and microgrids, and is a key technology to promote the replacement of main energy from fossil energy to renewable energy; energy storage can promote open sharing and flexible trading of energy production and consumption, and realize multi-energy synergy, and is the core foundation for building energy Internet, promoting power system reform and promoting the development of new energy formats.

In recent years, my country's energy storage has shown a good trend of diversified development: pumped storage has developed rapidly; compressed air energy storage, flywheel energy storage, superconducting energy storage and supercapacitors, lead-acid batteries, lithium-ion batteries, sodium-sulfur batteries, flow batteries and other energy storage technologies have accelerated their research and development and application; heat storage, cold storage and hydrogen storage technologies have also made certain progress. my country's energy storage technology has generally already preliminarily possessed the foundation for industrialization. Accelerating the development of energy storage technology and industry is of great strategic significance for building a "clean, low-carbon, safe and efficient" modern energy industry system, promoting the supply-side reform of my country's energy industry, and promoting changes in energy production and utilization methods. At the same time, it will also drive the development of the entire industrial chain from material preparation to system integration, and become a new driving force for improving the level of industrial development and promoting economic and social development. In order to implement General Secretary Xi Jinping's energy strategic thinking on "four revolutions and one cooperation", implement the tasks of the "Outline of the 13th Five-Year Plan for National Economic and Social Development of the People's Republic of China" and the "Energy Production and Consumption Revolution Strategy (2016-2030)", and promote the development of energy storage technology and industry, the following opinions are put forward.

I. General requirements

1. Guiding ideology

We will fully implement the spirit of the 18th CPC National Congress and the Third, Fourth, Fifth and Sixth Plenary Sessions of the 18th CPC Central Committee, thoroughly implement the spirit of General Secretary Xi Jinping's series of important speeches, and in accordance with the major decisions and arrangements of the Sixth and Fourteenth Meetings of the Central Financial and Economic Leading Group and the First and Second Meetings of the National Energy Commission, adapt to and lead the new normal of economic and social development, focus on the overall situation and long-term development needs of the energy industry, closely focus on reform and innovation, focus on mechanism breakthroughs, base on technological innovation, and use application demonstration as a means to vigorously develop "Internet +" smart energy, promote the development of energy storage technology and industry, support and promote the energy revolution, and provide technical support and industrial guarantees for my country's transformation from an energy power to an energy power and for improving the quality and efficiency of the economy.

2. Basic principles

Government guidance and enterprise participation. Strengthen top-level design, increase policy support, study and introduce supporting measures such as finance, and coordinate solutions to major common problems in industry innovation and development. Strengthen guidance and information services, promote the reasonable opening of energy storage facilities, and encourage diversified market players to participate in market competition fairly.

Innovation leads, demonstration takes precedence. Create an open and inclusive innovation environment, and encourage all forms of technological, mechanism and business model innovation. Give full play to the pilot role of demonstration projects, promote the trial of new energy storage technologies and models, and create a good atmosphere for mass innovation.

Market-led and reform-driven. Give full play to the decisive role of the market in resource allocation and encourage social capital to enter the energy storage field. In conjunction with the process of power system reform, gradually establish and improve the price formation mechanism of power market-oriented transactions and flexible resources, restore the commodity attributes of energy, and strive to break through institutional and mechanism barriers.

Overall planning and coordinated development. Strengthen overall planning and optimize the layout of energy storage projects. Pay attention to the coordinated development of upstream and downstream, and optimize the complete industrial chain from materials, components, systems, operations to recycling and reuse. Develop energy storage on the premise of ensuring safety, improve the standards, testing and certification system, ensure product quality and orderly competition. Promote the concept of green design, study and establish a tiered utilization and recycling system for energy storage products, strengthen supervision, and eliminate pollution.

(III) Development goals

The relevant work will be promoted in two phases in the next 10 years. The first phase will achieve the transition of energy storage from R&D demonstration to the early stage of commercialization; the second phase will achieve the transformation from the early stage of commercialization to large-scale development.

During the 13th Five-Year Plan period, a number of pilot demonstration projects with different technology types and different application scenarios were built; a number of major key technologies and core equipment were developed, and the main energy storage technologies reached the international advanced level; a preliminary energy storage technology standard system was established, forming a number of key technical specifications and standards; a number of commercial models that can be promoted were explored; and a number of competitive market players were cultivated. The development of the energy storage industry has entered the early stage of commercialization, and the key role of energy storage in the transformation of the energy system has begun to emerge.

During the 14th Five-Year Plan period, energy storage projects will be widely used, forming a relatively complete industrial system and becoming a new economic growth point in the energy field; fully mastering key energy storage technologies and core equipment with international leading levels, and some energy storage technologies and equipment will lead international development; forming a relatively complete technology and standard system and having international voice; a variety of energy storage business models based on the power and energy markets will flourish; and a number of internationally competitive market players will be formed. The energy storage industry will develop on a large scale, and the role of energy storage in promoting energy transformation and the development of the energy Internet will be fully demonstrated.
