Maximum Demand | [portable]

Thus, demand charges act as an economic signal: Flatten your load profile, and we’ll reward you.

Reality: A welding shop may use little kWh but has brutal 15-minute peaks. Demand can exceed energy charges.

For facilities with many non-critical loads, install a demand controller. It monitors real-time power and sheds loads (e.g., heaters, battery chargers, pool pumps) when consumption approaches the MD setpoint. maximum demand

(or peak demand) refers to the highest level of electrical power drawn by a system or consumer over a specific timeframe, typically a 15- or 30-minute interval. While energy consumption measures total electricity used (kWh), maximum demand measures the "peak rate" of that usage (kW or kVA). Why Maximum Demand Matters

In many regions (e.g., USA, India, Southeast Asia), rates range from per month. A facility with an MD of 500 kW paying $15/kW incurs $7,500/month —just for demand. Thus, demand charges act as an economic signal:

How to avoid maximum demand penalties in your electricity bill

Despite using the same amount of energy, Factory B will pay a drastically higher electricity bill. Why? Because the utility must build and maintain transformers, cables, and substations capable of delivering 100 kW instantaneously—even if that peak lasts only 15 minutes. For facilities with many non-critical loads, install a

Reducing Maximum Demand is a strategic process known as or Peak Lopping . Here are the most effective strategies:
