A14. How do you calculate maximum demand?

Maximum Demand (sometimes referred to as Capacity) can be calculated by identifying the highest amount of electricity used for any given day within the period.
  • Where Maximum Demand is for 5 minute intervals, the highest 5 minute interval usage that occurs during each ‘To Date’ period is identified and multiplied by 12 to obtain the maximum demand expressed in kW.
  • Where Maximum Demand is for 15 minute intervals, the highest 15 minute interval usage that occurs during each ‘To Date’ period is identified and multiplied by 4 to obtain the maximum demand expressed in kW.
  • Where Maximum Demand is for 30 minute intervals, the highest 30 minute interval usage that occurs during each ‘To Date’ period is identified and multiplied by 2 to obtain the maximum demand expressed in kW.
