Ningxia accelerates the grid connection of energy storage plants to fully play the role of peak

China Energy Storage Network: Since December last year, Ningxia has accelerated the grid connection of energy storage power plants, including many large-scale energy storage power plants with a capacity of 100 megawatts, and has also given birth to a number of local energy storage power plants of the largest scale. A series of energy storage projects have been connected to the grid and put into operation, making Ningxia's installed energy storage scale the second largest in the country. By the end of April, Ningxia has been grid-connected energy storage power plant 16 grid-connected total scale of 1.324 million kilowatts / 2.653 million kilowatt hours, including grid-side energy storage grid capacity of 1.286 million kilowatts, ranking first in the country. According to statistics, from January to April 2023, Ningxia grid-side energy storage accumulated 196 million kWh of charging, 164 million kWh of discharging, and 112 calls, improving the utilization rate of new energy by about 1.05 percentage points, increasing the grid consumption capacity by a maximum of 1.036 million kW during the daytime when new energy is in full swing, and increasing the peak capacity by a maximum of 0.99 million kW during the evening peak, further increasing the grid This further increases the flexibility of the power grid and gives play to the role of energy storage in supporting electricity.

Multiple energy storage technologies complement each other's strengths

The energy storage industry is characterised by a wide range of technological directions and a spiral of development. Each energy storage technology is suitable for different application scenarios, and the most suitable technology route must be chosen for a particular scenario. Compared with pumped storage, new energy storage technology has become the fastest growing and most promising form of energy storage due to its fast response, flexible configuration, short construction cycle and other advantages, and good matching with new energy development and consumption. China's new energy storage industry as a whole is at the stage of transition from R&D demonstration to the early stage of commercialisation. The National Development and Reform Commission and the Energy Bureau issued the "14th Five-Year Plan" for the implementation of new energy storage development, which clearly proposes to promote the development of diversified energy storage technologies, including sodium ion batteries, new lithium ion batteries, lead carbon batteries, liquid flow batteries, compressed air, hydrogen (ammonia) storage, and other energy storage technologies, Compressed air, hydrogen (ammonia) energy storage, thermal (cold) energy storage, etc. At the same time, many of the above cutting-edge technologies will be included in the demonstration, and pilot demonstrations such as the use of abandoned mine pits for energy storage will be encouraged to promote pilot demonstrations of new energy storage technologies on multiple time scales. For oil and gas companies that are accelerating their transition to new energy, the oil and gas industry is currently in a "golden period" of research and development of special energy storage technologies.
