电力现货市场建设迈入关键阶段

Core Insights - The construction of China's electricity spot market has entered a critical stage, with seven provincial-level markets officially operational as of August this year, and six others in trial runs, forming a basic framework of "unified market, two-level operation" [1] - The spot market serves as a core platform for electricity resource allocation and is crucial for ensuring energy security, with a trading system covering 26 provinces and over 6,000 power generation entities [1] - The spot market has begun to show its guiding role in the consumption of renewable energy, with inter-provincial market transactions of renewable energy reaching 7.75 billion kilowatt-hours, accounting for 36.5% of total transactions in the first eight months of this year [2] Group 1 - The rapid expansion of new energy installations and issues such as "abandoned light" during midday and supply pressure during peak hours indicate that the market mechanism needs further optimization to adapt to high proportions of renewable energy [1] - The inter-provincial spot market's maximum mutual assistance power reached 14.32 million kilowatts during peak summer electricity usage, effectively alleviating supply pressure in certain regions [1] - Zhejiang's spot market has successfully utilized market price signals to guide users in peak shaving, achieving a reduction of 3 million kilowatts and uncovering over 3.5 million kilowatts of user-side flexible adjustment capacity [2] Group 2 - The increasing share of renewable energy is profoundly changing the operational characteristics of the power system, with negative electricity prices becoming a common issue in regions with high renewable penetration [2] - It is suggested that the response to frequent negative electricity prices should be through mechanism optimization rather than administrative intervention, including controlling the pace of new energy installations and enhancing user-side flexibility [3] - A multi-layered system comprising "energy market + capacity market + ancillary services market" is proposed for future development, ensuring long-term supply capability and allowing flexible resources to gain reasonable returns [3]
