Energy storage is becoming the "new track" of China's power central enterprises

Under the guidance of China's "dual carbon" goal, energy storage, as an important support for the development of renewable energy and the construction of a new power system, is also becoming a "new power" in the competition of China's central power enterprises while the industrial development has entered the "fast lane". track".
    At the 28th Central Enterprise Think Tank Salon and the 3rd "Liupu Kang Energy Forum" hosted by the Central Enterprise Think Tank Alliance and undertaken by the General Institute of Hydropower and Water Conservancy Planning and Design on September 23 , "energy storage" became the participating experts and enterprise representatives repeatedly mentioned keywords. Yi Xuedong, director of the Research Center of the State-owned Assets Supervision and Administration Commission of the State Council of China, pointed out at the forum that the role of central enterprise think tanks should be brought into play to accelerate the coordinated development of new power systems.

The new power system is characterized by new energy as the main body, which determines that energy storage will play an important supporting role in its construction process. Li Sheng, Dean of the General Institute of Hydropower and Water Conservancy Planning and Design, believes that the construction of a new power system will go through three stages of gradual development. %; second, in the stage of accelerating construction, the path of low-carbon power system is basically clear and actively promoted. After the carbon emission of power system remains stable, it begins to decline, and the proportion of new energy electricity in some areas exceeds 50%; third, in the stage of full realization, zero-carbon power system The path is basically clear, various new technologies continue to make breakthroughs, coal power and other high-carbon power sources are withdrawn in an orderly manner, and new energy power accounts for more than 50% and continues to increase, becoming the main power consumer.

"It is necessary to scientifically understand the characteristics of existing renewable energy." Yue Guangxi, an academician of the Chinese Academy of Engineering, pointed out that under the existing technical conditions, it is necessary to correctly match the basic energy capacity and the capacity of unstable renewable energy to maintain the safe and stable operation of energy; energy storage is required. Only by making breakthroughs in new technologies such as flexible peak shaving, can reduce the proportion of basic energy capacity. "Energy storage is an essential measure for building a new type of power system in source, network, and load to realize the decoupling of power generation and use." Peng Cheng, chief technical expert of China Power Construction Group Co., Ltd., said that vigorously developing energy storage is an important current state-owned power enterprise. race track. In 2021, the State-owned Assets Supervision and Administration Commission of the State Council issued the "Guiding Opinions on Promoting the High-quality Development of Central Enterprises and Doing a Good Job in Carbon Peaking and Carbon Neutralization", which clearly stated that it is necessary to accelerate the construction of pumped storage power stations that are ecologically friendly, have mature conditions and excellent indicators. Promote the construction of projects under construction, actively carry out small and medium-sized pumped storage construction in combination with local planning, explore and promote the integration and transformation of water elevators, and develop a modern pumped storage industry. Promote the research and development and large-scale application of new energy storage technologies with high safety, low cost, high reliability and long life.

Zhang Zongliang, an academician of the Chinese Academy of Engineering, believes that the "14th Five-Year Plan" period is a critical period for my country's construction of pumped hydro storage, which is critical for building a new power system, promoting the large-scale and high-proportion development of renewable energy, achieving the goal of carbon peaking and carbon neutrality, and ensuring the power system. Safe and stable operation is of critical significance.

BAUFAR has learned from this forum that, according to incomplete statistics, under the guidance of policies, most of China's central power enterprises have or are deploying in the field of pumped hydro storage, and some of them are also involved in the field of new energy storage. "Scientific and technological innovation is an important way to build a new power system and solve the problems of energy transformation and development. As the main body of innovation, enterprises should continue to improve the technical level of clean and efficient energy development and utilization, and strengthen the research on cutting-edge technologies such as energy storage and hydrogen energy."
