Gone are the days of manual spreadsheet guesswork.

Create a table:

Used when designing a new installation. You sum all connected loads, then apply demand factors and diversity factors. maximum demand calculation

For the , MD is the basis for demand charges, often the largest component of an industrial electricity bill. A typical commercial tariff might charge $10 per kW of MD plus $0.10 per kWh. A factory with an MD of 1000 kW thus pays $10,000 in demand charges before any energy charges. Reducing MD by just 100 kW through load shedding or power factor correction saves $1,000 monthly—a powerful incentive. Gone are the days of manual spreadsheet guesswork

: Collect time-series load data from energy meters, supervisory control and data acquisition (SCADA) systems, or data loggers. Resolution should be at least 1-minute intervals, preferably 15- or 5-second intervals, to capture rapid changes. For the , MD is the basis for
