On May 31, the reporter learned from the Development and Reform Commission of Henan Province that Henan Province issued the Notice on Relevant Matters Concerning the Adjustment of Industrial and Commercial Time-of-Use Price, and since June 1, 2024, the industrial and commercial time-of-use price has been adjusted to better ensure the safe and stable economic operation of the power system. On the basis of improving the power supply and demand situation and promoting the consumption of new energy, it will further guide users to adjust the power load.
This adjustment makes detailed provisions on optimizing the setting of peak and valley time periods and adjusting the floating ratio of peak and valley. For example, in summer (June to August) and winter (January, February and December), the peak hours (including peak hours) of 8 hours per day (16: 00 to 24: 00) are implemented, in which the peak hours are from 17: 00 to 19: 00 in January and December, and from 20: 00 to 23: 00 in July and August; The trough period is from 0: 00 to 7: 00, and other periods are flat. From March to May and from September to November, the peak period is from 16: 00 to 24: 00, the low period is from 0: 00 to 6: 00, from 11: 00 to 14: 00, and other periods are flat.
Adjust the peak-to-valley price ratio, and the floating ratio of peak, flat segment and trough is adjusted to 1.72∶1∶0.45, and the floating ratio of peak is 1.2 times that of peak.
"Further improving the time-of-use electricity price, especially reasonably widening the price difference between peak and valley electricity prices, is conducive to guiding users to use more electricity during the low hours of the power system, creating more space for the development of new energy storage, and promoting the accelerated development and effective consumption of new energy sources such as wind power and photovoltaic power generation, with a view to achieving peak carbon dioxide emissions and carbon neutrality in the medium and long term." The relevant person in charge of the Henan Provincial Development and Reform Commission said that the adjustment of the industrial and commercial time-of-use electricity price is expected to achieve the following positive effects:
Promote the matching of power generation and consumption curves and the consumption of new energy. In order to solve the current imbalance between power generation and power consumption at noon, and ensure the safe and stable operation of the power grid, the three hours of concentrated photovoltaic output from 11: 00 to 14: 00 will be adjusted from peak hours to flat periods or low valleys, and users will be guided to adjust production load and use more electricity at noon, which is expected to reduce the light rejection rate by 1.61 percentage points.
Better serve the power supply. Appropriately extend the evening peak hours to 24: 00, and set the peak hours from July to August at 20: 00 to 23: 00, which can transfer 2.5 million kilowatts of evening peak load every year.
It is convenient for enterprises to adjust production time sequence. 16 consecutive hours from 0: 00 to 16: 00 are flat or low, and enterprises can produce continuously for a long time. At the same time, for enterprises with large daytime electricity consumption and poor load adjustment ability, the implementation of flat or valley electricity price at noon can reduce the impact of the current noon peak electricity price on electricity cost.
