Peak shaving is the process of reducing a facility's maximum power demand during periods when electricity prices are highest, typically late afternoon. Benefit: By using stored energy during peak hours, businesses can significantly lower their demand charges, as they are. . In markets such as China, Europe, and North America, the peak-to-valley price ratio can reach 3:1 or even higher. Over time, this erodes profits and limits production. . In an era of rising electricity costs, unpredictable peak demand charges, and growing pressure for energy independence, peak shaving energy storage is no longer a luxury—it's a necessity. Peak demand occurs in the morning and evening, straining the grid and risking outages when supply can't meet demand.
