What is DEMAND (KW) The term "demand' refers to the demand made by the customer upon the Company for the reserve of certain capacity. Whatever the energy requirements may be, we must maintain facilities with sufficient capacity to meet the maximum requirements of our customers. Even though these facilities may not always be used at full capacity, they are nonetheless required so that the electricity is available to customers whenever they want it. The demand charge reflects these capacity-related costs. Demand is the rate of electricity used (measured in kW) in 30-minute intervals. What is an ERIF?
