Peak shaving

Peak shaving reduces a site's highest electrical demand by controlling loads, using stored energy or combining both approaches. The aim is to keep short periods of high demand below a target level. On an EV charging site, chargers can be throttled when building demand is high, or a BESS can supply part of the load so less power is drawn from the grid. Peak shaving can reduce exposure to capacity constraints or demand-related charges where those apply. Its value depends on the site's load profile, tariff and available control assets.
