5 FAQs about Peak and valley electricity price energy storage equipment

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.

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.

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 much does a kWh cost in Guangdong?

In the five cities of the Pearl River Delta of Guangdong, the peak price was RMB 1.49/kWh, and the trough price was RMB 0.289/kWh, meaning a peak-to-trough gap of RMB 1.2/kWh, making Guangdong the province of the largest peak-to-valley spread as of mid-2023.
