GLOSSARY

  • Voltage Reduction
    If, after other steps to manage capacity have been taken and the demand for electricity continues to exceed generating capacity, the electric utility can reduce voltage by five percent. This reduction essentially stretches out the available supply of electricity to all customers. It is rarely noticed by customers but may affect sensitive electronic equipment.
  • Power Warning
    Public appeals when an immediate reduction in power usage is necessary to avert overload of the electrical system. Public appeals are made when other efforts (e.g. emergency purchases, voluntary curtailment, contracted curtailment and voltage reduction) have been unsuccessful in bringing supply and demand back into balance.
  • Power Caution
    Notification that electric reserves are lower than normal and steps are being taken by utility personnel to maintain the integrity of the on-line generation and transmission facilities.

FAQs

  • Q: What should customers do with appliances and electronic equipment?

    If power to your home or business is interrupted, the best thing to do is leave only a light or two on -- so you know when power is restored. Turn any air-conditioning appliances off, if possible. Keep any refrigerators or freezers closed as much as possible until power returns.

    Customers are asked to turn off electrical equipment during a blackout so that when power is restored, the system can return to normal as quickly as possible. If large equipment is not switched off, the surge of power trying to restart all of this equipment will trip a circuit breaker again. This could delay by hours the orderly restoration of power to an area.
