Battery energy storage significantly contributes to peak shaving by reducing electricity consumption during periods of high demand, thus stabilizing the power grid and lowering costs for consumers. Here’s how it works:
Contribution of Battery Energy Storage to Peak Shaving
- Energy Storage During Off-Peak Hours:
- Battery Energy Storage Systems (BESS) store energy during off-peak hours when electricity prices are generally lower. This stored energy can be drawn from the grid or generated by on-site renewable sources like solar or wind power.
- Discharging During Peak Hours:
- When demand for electricity peaks, the stored energy in the BESS is dispatched to meet part of the demand. This reduces the load on the electric grid, effectively shaving off the peak demand.
- Cost Savings:
- Peak shaving with BESS can lead to substantial cost savings, especially for commercial and industrial consumers who face high demand charges during peak hours. By using stored energy instead of grid power, they avoid paying premium prices for electricity.
- Grid Stability:
- By stabilizing demand spikes, BESS help maintain grid stability and reduce the strain on the electrical infrastructure. This is particularly important with the increasing integration of intermittent renewable energy sources.
- Flexibility and Resilience:
- Battery energy storage enhances the flexibility and resilience of the power grid, allowing it to better adapt to changing energy needs and unexpected outages.
