A reporter from China's ** newspaper recently learned from the Shanxi Provincial Energy Bureau that after five years of trial operation, the Shanxi electricity spot market has been transferred to formal operation since December 22, becoming the first officially operated electricity spot market in China. Industry insiders said that the electricity spot market is conducive to power supply, and when the power demand load is high, a higher ** can better stimulate the enthusiasm of coal power enterprises to generate electricity and achieve a balance between supply and demand. At the same time, higher electricity prices will optimize electricity consumption behavior and reduce peak electricity loads. In addition, the electricity spot market can bring additional income to energy storage, virtual power plants and other entities, promote industrial and commercial users to participate in market-oriented transactions, and facilitate the coordinated development of source, grid, load and storage.
Deepen the reform of the electric power system.
Shanxi is one of the first pilot provinces in China's electricity spot market. According to the Shanxi Provincial Energy Bureau, on December 27, 2018, the Shanxi electricity spot market started trial operation. Since the trial operation, the Shanxi electric power spot market has gone through 7 settlement trial runs, and the operation cycle has been gradually extended from a single day to weekly, semi-monthly, full month, and bi-monthly, and finally achieved continuous trial operation. The continuous trial operation time is as long as 32 months, and it has experienced the inspection of various supply and demand situations and different scenarios throughout the year, and the operation is stable and orderly.
In September 2023, the Electric Power Planning and Design Institute conducted an assessment of the electricity spot market in Shanxi Province. According to the assessment opinion, the Shanxi electric power spot market meets the conditions for trial operation to formal operation.
With the further deepening of the reform of the power system, the power market system has been continuously improved. At present, more than 60% of the total electricity consumption has been traded through the market, and the construction of a electricity spot market is an important measure to accelerate the construction of a new power system.
Since 2017, China has carried out two batches of electricity spot trading pilots. At present, six pilot provinces, including Guangdong, Shandong and Gansu, have carried out long-term settlement trial operation.
Improve the electricity market system.
In October 2023, the National Energy Administration issued the "Notice on Further Accelerating the Construction of the Electricity Spot Market", further clarifying the requirements for the construction of the spot market, further expanding the scope of business entities, coordinating the connection of various market mechanisms, and improving the operation guarantee capacity of the electricity spot market.
The notice requires Fujian to improve the design of the market plan as soon as possible and carry out the trial operation of long-term settlement by the end of 2023Zhejiang will speed up market convergence and start the trial operation of continuous settlement in the spot market before June 2024Sichuan continues to explore a market model and market mechanism that adapts to the high proportion of hydropower in the bumper and dry seasons. In addition, Liaoning, Jiangsu, Anhui, Henan, Hubei, Hebei, Jiangxi, Shaanxi and other provinces strive to carry out long-term settlement trial operation by the end of 2023.
Industry insiders said that Shanxi is at the forefront of the construction of China's electricity spot market, and has a strong demonstration role and reference significance for the relevant policy formulation of other provinces. CITIC ** believes that the power supply structure and load structure are different in various places, and the follow-up reform rhythm and measures will be different.
Huaxin believes that the electricity spot market is conducive to power supply, and in the time period of high power demand load, a higher ** can better stimulate the enthusiasm of coal power enterprises to generate electricity and achieve a balance between supply and demand. At the same time, high electricity prices will optimize electricity consumption behavior, reduce peak electricity loads, and facilitate the consumption and utilization of renewable energy. In addition, the electricity spot market can bring additional income to entities such as energy storage and virtual power plants, and promote industrial and commercial users to participate in market-oriented transactions, which is conducive to the coordinated development of source, grid, load and storage.
Under the power market system of "medium and long-term + spot + ancillary services", it is the basic principle to give priority to the consumption of new energy, and thermal power units have flexible peak regulation capacity to reduce costs.
