Demand is the highest amount of electricity used at any one time. Demand is instantaneous use at a given moment.
For example, the more appliances being used all at once, the higher the demand for the electrical system. Using the electric oven, washing machine, clothes dryer, microwave, and space heater at one time creates greater demand than only using the oven and washing machine at once.
As your power provider, SEC must meet members' demands for electricity. SEC must be ready for the fluctuations in demand, including the highest peaks. The demand billing rate recovers our cost to make power available to you at any given point during the day. In order to recover those costs fairly, we apply the rate individually, based on the maximum amount of power you use at one time during the month.
