Use peak and valley electricity price energy storage project

Can user-side energy storage projects be profitable?

At present, user-side energy storage mainly generates income through the arbitrage of the peak-to-valley electricity price difference. This means that if the peak to valley price difference is higher than the levelized cost of using storage (LCUS), energy storage projects can be profitable.

How to improve peak-valley price mechanism?

1. Improve the peak-valley price mechanism. l Scientifically divide peak and valley periods. All localities should consider the local power supply-demand status, system power load characteristics, the proportion of new energy installed capacity, system adjustment capabilities, and other factors.

What should be considered when determining the peak-valley price?

Where the proportion of installed renewable energy power generation capacity is high, full consideration should be given to the fluctuation of new energy power generation output and the changing characteristics of the net load curve. l Reasonably determine the peak-valley price.

How many provinces have a peak to Valley electricity price difference?

The State Grids and China Southern Power Grids of 29 provinces, autonomous regions and municipalities announced the electricity tariffs for industrial and commercial users in December 2021. According to the statistics, 14 provinces and cities have a peak to valley electricity price difference that exceeds 0.7 yuan/kWh.

What is a deep valley electricity price mechanism?

Where cogeneration units and renewable energy have a large proportion of installed capacity, and where the contradiction between phased oversupply and demand in the power system is prominent, a deep valley electricity price mechanism can be established concerning the peak electricity price mechanism.

How do I determine the peak-valley price gap?

l Reasonably determine the peak-valley price. All localities should consider the local power system peak-valley ratio, the proportion of new energy installed capacity, system adjustment capacity, and other factors, and reasonably determine the peak-valley price gap.
