On June 5, the Development and Reform Commission of Guizhou Province issued a public announcement on the Notice on Improving Peak-Valley Time-of-Use Electricity Price (Draft for Opinions). According to
the document, the role of electricity price signals in optimizing the allocation of power resources will be strengthened to better serve the construction of new power systems with new energy as the main body, promote green and low-carbon development of energy, and improve the efficiency of power system operation.
In view of the implementation of two-part tariff for industrial and commercial users (including market-oriented and agent power purchasing users), centralized charging and replacement facilities for electric vehicle, and peak-valley time-sharing tariff for power storage in Guizhou power supply area, the peak-valley period will be divided into peak, flat and valley periods of 8 hours each, and the peak-valley period will be divided into peak, flat and valley periods. The details are as follows:
peak period: 10: 00-13: 00, 17: 00-22: 00;
average period: 8: 00-10: 00, 13: 00-17: 00, 22: 00-00: 00;
valley period: 00: 00-8: 00.
The peak-to-valley price ratio was adjusted from the current 1.5: 1: 0.5 to 1.6: 1: 0.4. That is to say, the peak section price rises by 60 % on the basis of the flat section price, and the valley section price falls by 60 % on the basis of the flat section price. Government funds and additional and basic electricity charges do not participate in the floating.

Notice
on Matters Related to Improving Peak-Valley Time-of-Use Electricity Price (Draft for Soliciting Opinions)
Municipal (State) Development and Reform Commission (Bureau), Guizhou Power Grid Co., Ltd., Guizhou Electric Power Trading Center, Incremental distribution network enterprises:
In order to implement the national green development requirements, give full play to the role of electricity price signals in guiding the optimal allocation of power resources, better serve the construction of new power systems with new energy as the main body, promote the green and low-carbon development of energy, and improve the operation efficiency of power systems, According to the Notice of the National Development and Reform Commission on Further Perfecting the Time-of-Use Electricity Price Mechanism (Development and Reform Price [2021] 1093) and other relevant provisions, combined with the actual changes in the power supply situation in our province. The notice on improving the time-of-use electricity price in our province is as follows:
I. Expanding the scope
of implementation The industrial and commercial users (including market-oriented and agent power purchasing users), electric vehicle centralized charging and switching facilities, and electric energy storage in the power supply area of our province that implement the two-part electricity price system shall implement the peak-valley time-of-use electricity price. Among them, public service electricity such as electrified railway traction, urban public transport, schools, hospitals, tap water production, urban and rural sewage treatment plant production, sewage pumping station production, garbage harmless treatment plant (yard) production, garbage transfer station production and so on does not implement peak-valley time-of-use electricity price.
2. Optimize the division
of peak and valley periods. According to the current load situation of the power system in our province, the peak and valley periods are divided into peak, flat and valley periods of 8 hours each 24 hours a day. The details are as follows:
peak period: 10: 00-13: 00, 17: 00-22: 00;
average period: 8: 00-10: 00, 13: 00-17: 00, 22: 00-00: 00;
valley period: 00: 00-8: 00.
3. Expand the peak-valley electricity price level. The peak-flat-valley price ratio is adjusted from the current 1.5: 1: 0.5 to 1.6: 1: 0.4, that is, the peak-valley electricity price rises by 60% on the basis of the flat-valley electricity price, and the valley-valley electricity price falls by 60% on the basis of the flat-valley electricity price. Government funds and additional and basic electricity charges do not participate in the floating.
4. Improve the settlement method
of peak and valley electricity price (1) Reasonably determine the flat section electricity price. In which, the average section price of agency power purchase user = monthly agency power purchase price + power transmission and distribution price + line loss cost of on-grid link; the average section price of market transaction user = average section transaction price + power transmission and distribution price + line loss cost of on-grid link + system operation cost.
(2) Establish a profit and loss sharing mechanism for peak and valley time-of-use electricity prices. The profits and losses arising from the implementation of peak-valley time-sharing electricity price shall be shared or apportioned by all industrial and commercial users on a monthly basis. Profit and loss of peak-valley time-sharing electricity price of the month = peak-valley profit and loss of agent power purchasing user + peak-valley profit and loss of market transaction user. Among them, the peak-valley profit and loss of the agent power purchasing user in the current month = ∑ (the peak electricity quantity of the current month × the peak electricity price + the average electricity quantity of the current month × the average electricity price + the valley electricity quantity of the current month × the valley electricity price)-∑ the average electricity price of the current month × the electricity consumption of the agent power purchasing user in the current month; The peak-valley profit and loss of the market transaction user in the current month = ∑ (the electricity quantity in the peak section of the current month × the electricity price in the peak section + the electricity quantity in the average section of the current month × the electricity price in the average section + the electricity quantity in the valley section of the current month × the electricity price in the valley section)-∑ the electricity price in the average section of the current month × the electricity consumption of the market transaction user in the current month.
5. Other matters
(1) Users who implement peak-valley time-of-use electricity prices must install time-of-use metering devices to measure electricity consumption in peak, valley and flat sections respectively. Power grid enterprises should pay close attention to the commissioning of metering devices, and before the commissioning of user metering devices is completed, the division of peak and valley periods shall be temporarily implemented in accordance with the original relevant provisions.
(2) If an independent energy storage power station transmits electricity to the power grid, its corresponding charging capacity shall not bear the transmission and distribution price, government funds and additional charges.
(3) By December 31, 2025, the basic electricity charges for centralized charging and replacement facilities for electric vehicle will be exempted.
(4) For users who implement the policy of peak-valley time-of-use electricity price, if the metering device is not at the boundary of property rights, the loss of transformers and lines shall be calculated by converting the electricity quantity of each period into the electricity quantity of each period according to the proportion of the electricity quantity of each period of peak-valley. Power factor adjustment of electricity charges is based on the method of power factor adjustment of electricity charges stipulated by the state, which is based on the electricity charges (deducting government funds and surcharges) and basic electricity charges after the implementation of peak-valley fluctuation by users.
6. Relevant requirements
(1) Municipal (state) development and reform departments shall, in accordance with the requirements of this circular, carefully organize, carefully arrange and strengthen publicity to ensure the full implementation of the requirements of this circular. Effectively strengthen business guidance and urge incremental distribution network enterprises to implement the provisions of this circular.
(2) Guizhou Power Grid Co., Ltd., power supply bureaus at all levels, Guizhou Electric Power Trading Center and incremental distribution network enterprises should actively publicize policies to users and effectively strengthen services.
(3) This Circular shall be implemented as of January, 2023, and the problems arising in the implementation shall be reported to the Provincial Development and Reform Commission in a timely manner. Development and Reform Commission
