China Energy Storage Network: State Grid Ningxia Electric Power Co., Ltd. Zhongwei Power Supply Company provided data showing that as of May 26, Zhongwei grid has now been grid-connected energy storage power station 2, capacity 350MW/700MWh, has accumulated 81.978 million kWh of charging, discharge 68.355 million kWh, equivalent to 26,200 tons of standard coal generated, reduce 64,400 tons of carbon dioxide emissions.
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.
China energy storage network: Xinjiang will establish independent energy storage capacity tariff compensation mechanism, in the national introduction of a unified new energy storage capacity tariff policy, the independent energy storage in operation in Xinjiang first in accordance with the discharge volume to implement 0.2 yuan / kWh of capacity compensation, 2024 onwards declining 20% per year until 2025. This is one of the main contents of the "notice on the establishment of sound supporting policies for the healthy and orderly development of new energy storage" recently issued by the Development and Reform Commission of the autonomous region.
China's oil companies to enter the energy storage market still need to find a good breakthrough, based on their own advantages to carry out research and development at the same time, with the help of external high-quality resources, the development of energy storage technology and equipment applicable to the oil and gas industry features, the establishment of sound use of norms, industry standards, regulatory system, pay attention to safety and sustainable development, make full use of the oil area photovoltaic, wind power, geothermal and other renewable energy, accelerate energy storage supporting new energy industry layout In addition, we will complete the clean replacement of energy used in oilfield production, promote low-carbon transformation development and help the country achieve the "double carbon" target.
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.
China's oil and gas companies have a large oil area in the "Three Norths" region, which is rich in solar and wind energy resources. Accelerating the deployment of centralised and distributed wind and solar power generation in oil areas, promoting the electrification of oil and gas field terminals and achieving green power supply, is an important way to achieve clean alternatives. However, new energy generation is intermittent, random, volatile and seasonal, and large-scale access will pose a huge challenge to the safe and stable operation of the grid. Energy storage can effectively suppress new energy power fluctuations, promote balance between power and load, reduce wind and light abandonment, and is a key support technology for new energy power generation. China vigorously promotes scenery with storage, as of August 2022, nine provinces and municipalities have made clear requirements for scenery power generation with energy storage, with a ratio of 5%-30%.
