GLOSSARY

  • Power Watch
    Advisories to be announced when conditions are such that further steps to manage capacity could affect the public.
  • Power Interruption Alert
    When possible, the public would be alerted that load shedding or rolling blackouts are imminent.
  • 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.

FAQs

  • Q: How does one remain on the CONVEX Authorized Personnel List?

    The individual will be placed on the Authorized Personnel List (APL) for the location specified by their supervisor. If the individual transfers to another location, CONVEX will need to receive a letter from their Supervisor or New Supervisor that the individual is knowledgeable of the equipment at the new location and request the APL be changed to the new location.

    Everyone on the Authorized Personnel List (APL) is required to attend a one-half day Switching and Tagging Refresher Course every three (3) years to remain on the Authorized Personnel List.
