Comprehensive Guide: Maximum Demand Calculation

1. What is Maximum Demand?

Maximum Demand (MD) is the highest average power (kW, kVA, or A) drawn by an electrical installation over a specified time interval (typically 15, 30, or 60 minutes) during a billing or assessment period.

Part 1: What is Maximum Demand? (Beyond the Basic Definition)

Maximum Demand is defined as the highest average load (in kilowatts, kVA, or amperes) that occurs within a specified time interval over a billing period. The interval is typically 15, 30, or 60 minutes, depending on the utility company. maximum demand calculation

While specific formulas vary by region, the logic generally follows these steps: Comprehensive Guide: Maximum Demand Calculation 1

Method A: The Diversity Factor Method (Design Stage)

Used when designing a new installation. You sum all connected loads, then apply demand factors and diversity factors. Part 1: What is Maximum Demand

: Restricting the demand by using a protective device (like a circuit breaker) with a fixed rating that the installation cannot exceed. Assessment

Part 6: Advanced Strategies – Controlling Maximum Demand

Once you calculate MD, the next step is active management. You want to lower the MD without stopping production.

Assuming a diversity factor of 0.8, the maximum demand can be calculated as:
