Maximizing Benefits from Peak-Valley Price
As part of user-side energy storage projects, the operation mode is “peak shaving and valley filling,” effectively regulating electricity
1. Peak-Valley Price Arbitrage Peak-valley electricity price differentials remain the core revenue driver for industrial energy storage systems. By charging during off-peak periods (low rates) and discharging during peak hours (high rates), businesses achieve direct cost savings. Key Considerations:
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.
As the peak-valley electricity price difference, annual average irradiance and annual average wind speed decrease, the optimal allocation capacity and the annual net revenue of the BESS also decrease.
On the one hand, the battery energy storage system (BESS) is charged at the low electricity price and discharged at the peak electricity price, and the revenue is obtained through the peak-valley electricity price difference. On the other hand, extra revenue is obtained by providing reserve ancillary services to the power grid.
