6 FAQs about [Use peak and valley electricity price energy storage project]

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 is the value of energy storage?

The value of energy storage is that the prosumer will store part of the surplus generation and use it for their own use when the electricity price is high.

What if Peak-Valley ratio exceeds 40%?

When the peak-valley ratio is expected to exceed 40% in the previous year or the current year, in principle, the electricity price difference should not be less than 4:1; and it should not be less than 3:1 in other places. 2. Establish a peak electricity price mechanism.

Does peak-valley spread affect peak-shaving of the power grid?

Although wider peak-valley spread promotes cost-savings for LEM participants, the effects on peak-shaving of the power grid is marginal. This is because the peak-valley mechanism is still insufficient to identify all potential spikes in power supply, so the storage and reserve capacity resources cannot reach the efficient allocation.

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.

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.
