Household peak and valley electricity prices and energy storage

When is peak and Valley electricity consumption?

There are three peak values and three valley values every year, with peak periods in February, May, and September and valley periods in March, June, and November. The variation in peak and valley electricity consumption of urban residents is closely related to holidays and the demand for comfortable living.

What is residential electricity consumption behaviour?

Residential electricity consumption behaviour is an essential expression of the demand-side response in the power system. Sharing energy storage facilities and backup resources on the energy-using side can effectively regulate grid balance.

How do C&I energy storage projects benefit from Peak-Valley arbitrage?

C&I energy storage projects in China mainly profit from peak-valley arbitrage while reducing demand charges by monitoring the inverters’ power output in real time to prevent transformers of industrial parks from exceeding their capacity limits.

What is the standard for peak and Valley price fluctuations?

The same standard exists for peak and valley price fluctuations; i.e., the standard of peak hours will be 50% higher than the standard of flat hours, while the standard of low valley hours will be 50% lower than the standard of flat hours (Provincial Gansu Development and Reform Commission, 2020).
