## What does peak demand mean?

Peak demand, peak load or on-peak are terms used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than average supply level. Peak demand fluctuations may occur on daily, monthly, seasonal and yearly cycles.

## What is maximum demand electricity bill?

Maximum demand term or Maximum demand indicator (MDI) This is the maximum power value, usually the average of 15 minutes, reached during the billing period (this average time may vary depending on the country). Once the value is higher than the contracted power, the customer will pay a penalty on the electricity bill.

## Is it cheaper to do laundry at night or during the day?

## How do you calculate maximum demand load?

For example, the maximum demand of a 240 V single-phase 8 kW shower heater can be calculated by dividing the power (8 kW) by the voltage (240 V) to give a current of 33.3 A.

## How can peak demand be reduced?

Another way to reduce peak demand is to install equipment that uses less energy. Using more efficient equipment reduces the base load of energy used at all times, effectively shrinking the entire demand curve in a downward direction. … This would then reduce the peak demand load down to 975 kW.

## What is the difference between peak and off peak electricity?
