On August 8, the Shandong Regulatory Office of the National Energy Administration issued the "Notice on soliciting opinions on the" Shandong Power Climbing auxiliary Service Market Trading Rules (Draft for Comments) ", marking the official release of the draft for comments on the first domestic climbing auxiliary service market trading rules.The draft for comments include 36 articles related to the basic principles, market members, and organizations of climbing auxiliary services market trading, and etc. The “Compilation Instructions for Shandong Electric Power Climbing Auxiliary Services Market Trading Rules” points out that the current regulating capacity of the Shandong power system is not sufficient to meet actual demands. During the operation of the spot market, there have been instances of insufficient system regulating capacity in some time periods. In 2022, the real-time market experienced a total of 219 instances of insufficient ramp capacity, accounting for 0.625% of the time periods. Among them, 179 instances were peak ramping storage, mainly concentrated between January and May, and 40 instances were peak-load regulation climbing storage (imbalances even after the curtailment of renewable energy), occurring in February. The insufficient regulating capacity on the system's part has led, on the one hand, to the emergence of peak electricity prices, increasing electricity costs. On the other hand, it has added pressure to the secondary frequency regulation of the system, which is detrimental to the secure and reliable operation of the power grid.
