Guide industrial and commercial off-peak electricity consumption and Beijing time-of-use electricity price to advance
Beijing's time-of-use electricity price mechanism has been optimized again. According to the requirements of the National Development and Reform Commission, combined with the specific situation of Beijing, after soliciting opinions from the public and fully researching and demonstrating, recently, the Beijing Municipal Development and Reform Commission officially issued the "Notice on Further Improving the City's Time-of-Use Electricity Price Mechanism and Other Related Matters" (hereinafter referred to as the "Notice") to optimize the peak-to-valley period and peak-to-valley price difference of electricity prices, further play the role of electricity price signals, guide industrial and commercial users to stagger peak power consumption, and better ensure the safe, stable and economic operation of the power system. After the adjustment of the peak-to-valley time-of-use electricity price mechanism, the price of electricity for residents will not be affected, the cost of electricity for agriculture will be stable and falling, and the electricity fee for small, medium and micro businesses will remain basically stable.
Optimize peak-to-trough hours and spreads
According to the relevant person in charge of the Beijing Municipal Development and Reform Commission, the "Notice" mainly improves the current time-of-use electricity price from the aspects of clarifying the scope of implementation, optimizing the division of time periods, and adjusting the peak-to-valley price ratio.
In terms of the scope of implementation, the scope of implementation of the city's time-of-use electricity price policy is clearly defined as all industrial and commercial users except for subways, trolleybuses, and electrified railway traction electricity, and the implementation scope of the peak electricity price policy is industrial and commercial users with a transformer capacity of 100 thousand volt amperes (kilowatts) and a voltage level of 1 thousand volts and above.
At the same time, the adjustment has further optimized the division of time periods, and the annual peak and valley periods are divided into three sections of peak, flat and trough for 8 hours each according to 24 hours, and the peak hours are adjusted from the original 5 hours during the day and 3 hours at night to 3 hours during the day and 5 hours at night, and the valley section remains unchanged, and the peak electricity price of 3 hours per day is implemented in summer (July and August) and winter (December and January) respectively.
In addition, the peak-to-valley price ratio has also been adjusted this time, and the peak-to-valley electricity price ratio of the unitary system has been adjusted to 1.71:1:0.36 (less than 1,000 volts) and 1.8:1:0.3 (1,000 volts and above), and the peak-to-valley electricity price ratio of the two-part system has been uniformly adjusted to 1.6:1:0.4. The peak price is 20% higher than the peak price.
Residential electricity prices will not be affected
According to reports, Beijing's improvement of the time-of-use electricity price mechanism is a specific measure to implement the national requirements. The National Development and Reform Commission requires all localities to further improve the time-of-use electricity price mechanism, and puts forward specific requirements for the scope of implementation, peak-to-valley periods, and peak-to-valley price differences.
The relevant person in charge of the Beijing Municipal Development and Reform Commission said that the time-of-use electricity price is conducive to improving the overall utilization efficiency of the power grid. Based on the time value of electric energy, the time-of-use electricity price mechanism divides the daily time into three periods: peak, flat and trough, and formulates different electricity price levels respectively, so as to give full play to the role of electricity price signals, and guide power users to use less electricity during peak hours and more electricity during trough hours, so as to ensure the safe and stable operation of the power system and improve the overall utilization efficiency of the system.
In addition, the city's time-of-use electricity price mechanism needs to be further improved. Beijing is one of the earliest provincial-level regions in the country to implement the time-of-use electricity price mechanism, and over the years, it has repeatedly expanded the implementation scope of peak and valley electricity prices, adjusted the peak and valley electricity price periods, and better played a role in guiding the price leverage of resources to rational allocation and utilization. With the optimization of the energy structure and the adjustment of the power consumption structure, the characteristics of the city's time-based power load are also constantly changing, and it is necessary to further improve the time-of-use electricity price mechanism.
"The improvement of the time-of-use electricity price mechanism has little impact on the total cost of electricity in the society, the income of power grid enterprises remains unchanged, and the overall level of sales electricity prices remains basically stable. The relevant person in charge of the Beijing Municipal Development and Reform Commission said that in addition to the price of electricity for residents is not affected, the cost of electricity for agriculture has been steadily reduced, and the electricity cost of small, medium and micro businesses has remained basically stable.
Specifically, the price of electricity for residents will not be affected, and the adjustment scope of the time-of-use electricity price plan will be industrial and commercial electricity, and the cost of electricity for residents will not be affected; the cost of electricity for agriculture will be stable and decreasing; the peak-to-valley time-sharing of agricultural electricity will be cancelled, and the cost of agricultural electricity will be further reduced, and the cost of electricity for agriculture will be implemented according to the flat electricity price, and the cost of electricity will be reduced by about 1 cent, with an average annual cost of 18 million yuan; the electricity fee of small, medium and micro businesses will remain basically stable; considering that the peak regulation capacity of small and medium-sized micro businesses is weak, the peak-to-valley price ratio of industrial and commercial users less than 1,000 volts will be maintained at the original low level, and the peak electricity price will not be implemented for the time being, so as to ensure that the electricity bill of most users remains basically stable。
The cost of electricity will decrease during the trough period
Due to the reasonable widening of the peak-to-valley electricity price spread, the electricity cost of users who can use electricity at off-peak times and use more electricity during trough hours will decrease, and on the contrary, they need to bear the increased power supply costs during peak hours. In other words, if the majority of industrial and commercial users actively optimize their own electricity consumption behavior within the scope of peak regulation capacity, the burden of electricity bills will be further reduced.
For example, a restaurant with an annual electricity consumption of 50,000 kWh has a peak, flat and valley electricity ratio of 40%, 35% and 25% respectively, which belongs to the unitary electricity consumption mode of less than 1,000 volts in the suburbs. Before the policy adjustment, the merchant spent about 47,100 yuan on electricity every year. After the policy is perfected, if the electricity consumption habits remain unchanged, the electricity expenditure will be about 46,800 yuan, a decrease of 0.03 thousand yuan, or 0.6%, of which the adjustment of the peak-to-valley price ratio will affect the electricity expenditure of about 0.02 thousand yuan, and the adjustment of the peak period and price ratio will affect the electricity expenditure of about 0.01 thousand yuan.
If the restaurant has the willingness to adjust the peak regulation, and actively adjusts 5% of the peak electricity to the valley section by adjusting electricity consumption habits, energy-saving transformation, energy storage and other methods, then the annual electricity bill of the merchant can be reduced to 45,500 yuan.
"The further improvement of the time-of-use electricity price mechanism can better guide users to stagger peak power consumption, ensure the safe and stable operation of the power system, reduce economic and social operating costs, and at the same time facilitate the consumption of green electricity and provide more space for the development of the energy storage industry. The relevant person in charge of the Beijing Municipal Development and Reform Commission said.
It is worth noting that the "Notice" also emphasizes that all non-grid direct power supply entities shall collect electricity fees from end users in strict accordance with the market-based transaction price of electricity or the peak and valley time-of-use electricity price purchased by power grid enterprises on behalf of power grid enterprises, and shall not add other fees to the electricity charges of end users.
