The energy storage power station shall quote based on the charging amount. If it is called in sequence, the charging plan shall be determined by the energy storage power station based on the market clearing results before the day, and the charging power shall be adjusted in real-time according to the daily peak shaving demand. The bid winning price shall be its quotation. If prioritized, the energy storage station will charge according to the daily plan, and its declared price will participate in the overall market ranking. If its declared price is lower than the actual market call * high price, the bid winning price shall be its declared price; If its declared price is higher than the actual market call * high price, the bid winning price is the same period of market * low price.
Energy storage is prioritized for ensuring the safe and stable operation of the power grid, power supply, and clean energy consumption. When necessary, the dispatch center can adjust the market clearance results or charging and discharging plans of the energy storage power station as needed, and inform relevant energy storage entities in advance, and keep records to explain the reasons for mandatory calls for future reference.

The final declaration shall be a valid declaration before and after the transaction declaration deadline.
（1） Thermal power units are quoted based on reduced power generation. Based on the benchmark value of paid peak shaving for thermal power units, set 6 quotation intervals and declare the compensation price for reduced electricity generation. As the depth of peak shaving increases, the quotation should be based on the non decreasing principle, and a small adjustable output should be declared.
If called in sequence, the bid winning price is the quotation corresponding to the load rate of the unit issued by the scheduling command during the trading period. If the output of the unit is higher than the dispatch command value, the bid price shall be the quotation corresponding to the actual load rate of the unit during the trading period.

Allocation fee for deep peak shaving service fee of a certain market entity=(total deep peak shaving service fee - load side market entity service fee) ×∑ (During this trading period, the service buyer's online electricity consumption × Ki)/∑ (the online electricity consumption of each service buyer during the trading period × Ki)
Article 34 【 Allocation Adjustment Coefficient 】 Considering the differences in benefits for buyers of different types of deep peak shaving services in deep peak shaving services, a allocation adjustment coefficient Ki shall be set.
（1） The allocation adjustment coefficient for Qishao DC transmission to other provinces is K1.

The service buyer shall not exceed their approved grid electricity price (or coal-fired power generation benchmark price) for the cost of electricity sharing during a single deep peak shaving trading period.
The value of Ki can be found in Annex 4 "Auxiliary Service Market Coefficient Table".
Article 35 [Connection with Medium and Long Term Trading] The seller's units participating in deep peak shaving trading shall not be deemed to have exceeded or missed the monthly deviation assessment for medium and long term trading due to their own reasons.
Article 36 [Invalid Service] If the seller's unit's output drops below the paid peak shaving reference value due to its own reasons such as startup, shutdown, or non shutdown, it shall not be considered as providing deep peak shaving service.
Article 37 [Exemption from Allocation] The situations where allocation may be exempted are as follows:
