Commercial and industrial energy storage is about to explode!
On November 28, the Development and Reform Commission of Fujian Province issued a notice on improving the time-sharing tariff policy. The notice states that in order to strengthen synergy with the market, deepen the construction of the medium- and long-term, spot and auxiliary service markets for electricity, and further optimize the peak-valley price differential through the market formation of time-sharing tariffs, the tariff policy will be implemented from January 1, 2024, with a validity period of five years.
Adjusting the division of time periods and the floating range of peaks and valleys.
The province's peak hours are 10:00-12:00, 15:00-20:00, 21:00-22:00;
The valley period is 0:00-8:00;
The rest are the usual periods.
The upward fluctuation rate is 58% during peak hours and
63% downward fluctuation during valley hours.
The peak to valley ratio is 4.27:1.
The peak tariff is set up from July to September, 11:00-12:00 and 17:00-18:00 are the peak hours, and the upward fluctuation rate is 80%.
If based on this condition, industrial and commercial energy storage customers in Fujian Province can develop the following charging and discharging strategies：
Overall, the further improvement of the time-sharing tariff mechanism, to maintain the basic stability of the average price of industrial and commercial users, is conducive to better guide the user peak shaving and filling in the valley, improve the supply and demand situation of electricity, and promote new energy consumption, whether it is for the short term to ensure the security and stability of the economic operation of electric power, or for the medium and long term to achieve the goal of carbon peaking and carbon neutrality are of positive significance.
It is reported that as of October 2023, Fujian Province, compared with the end of 2015 ("12th Five-Year Plan" period), the proportion of coal-fired units with strong peak shifting capacity has decreased from 70% to 37.4%, while the proportion of nuclear power with relatively weaker peak shifting capacity has reached 14.5%, and the pressure on peak shifting has increased, and at the same time, the proportion of installed new energy sources, such as wind and solar power, has reached 19.2%, and the proportion of their output has reached 19.2%. reached 19.2%, its output does not match with the peak hours of electricity consumption, and, the difference between peaks and valleys of electricity consumption is large and long, in 2022, the maximum difference between daily electricity consumption in the province peaks and valleys of 14.47 million kilowatts, and the maximum difference between peaks and valleys of more than 10 million kilowatts of the number of days there are 162 days.
