GLOSSARY

  • Power Watch
    Advisories to be announced when conditions are such that further steps to manage capacity could affect the public.
  • 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.
  • Conservation Day
    Public appeal to customers to conserve electricity in anticipation of heavy electrical demand and unhealthy air quality conditions, usually due to humid weather.

FAQs

  • Q: What effect does a voltage reduction have on my service?

    Generally, a voltage reduction would have no noticeable effect on your service. Standard household appliances and electrical equipment are designed to tolerate a ten per cent change in voltage. Utilities regularly perform five percent voltage reduction tests with little notice to customers. 

    Customers concerned about their electric service or sensitive electronic equipment should check their equipment manuals or with their equipment suppliers about precautionary measures to protect equipment or data. Computer users should save files and data frequently.
