Peak demand is the greatest instance of power usage in a given time frame, typically a fifteen minute interval, and is measured in kilowatts (KW). Peak demand charges encourage property managers to minimize energy consumption.
Why it Matters
Peak demand times tend to be at the beginning of the workday, when buildings are starting up in the morning. To mitigate against peak demand charges, engineers can stagger equipment start times. Energy management software can help you reduce peak demand costs by alerting you when there is an irregular spike in consumption.
