Paying too much for hydro?

摘要

When did you last analyze your electrical utility bill? Have you seen a charge for demand and wondered what it's for? As a hydro user, you are billed based on the amount of electrical energy you consume measured in Kilowatt hours (Kwh). One Kwh is theenergy required to run a 100 watt light bulb for 10 hours or a 1000 watt heater for one hour. The total energy consumed between meter readings will account for the energy charge of your bill. The second part of your bill is the demand charge. Demand charge is not a physical property of electricity, but rather a charge to cover the utility's cost of maintaining excess capacity to meet the large peek electrical requirements of a customer. When we turn on any electrical device we have become accustomed tothe fact that enough electrical power will be available instantaneously to supply our various needs.
