Peak load shaving is a strategy used to reduce the maximum demand for electricity during peak usage times. This is important because high demand can strain the electrical grid, leading to increased costs and potential outages. By lowering the peak load, utilities can manage resources more efficiently and maintain a stable supply of electricity. Methods for peak load shaving include using energy storage systems, such as batteries, and demand response programs that encourage consumers to reduce their energy use during peak hours. These approaches help balance the load on the grid and can lead to cost savings for both utilities and consumers, while also promoting sustainability.
