Definition
Peak shaving is the practice of reducing a facility's highest instantaneous power demand during periods when electricity is most expensive or the grid is most constrained. Because commercial utility bills often include steep "demand charges" based on a site's single highest 15-minute draw of the month, trimming those peaks can cut the bill significantly even if total energy consumed stays the same.
How it works
The most common method is to pair the load with a battery energy storage system: the battery charges from the grid (or on-site solar) during cheap off-peak hours and discharges during peaks, so the meter never sees the full spike. Alternatively, dispatchable loads can simply curtail. Bitcoin mining is uniquely suited to the curtailment approach—ASICs can throttle or pause within seconds, letting an operator shed load during peak-price intervals and resume when rates fall.
Why miners care
Peak shaving reshapes the relationship between a mining operation and its utility. By capping instantaneous demand, a site can sometimes connect to a smaller, cheaper interconnection than its nameplate would otherwise require, and it can participate in demand-response programs that pay miners to reduce load. Combined with off-peak charging and an inverter-based storage stack, peak shaving turns a volatile power bill into a managed cost—one of the levers that keeps marginal mining economics viable.
