GLOSSARY

  • Power Interruption Alert
    When possible, the public would be alerted that load shedding or rolling blackouts are imminent.
  • Rolling Blackouts
    Temporary interruption of electrical service. ISO New England would implement rolling blackouts only if and when New England's electrical system is unable to meet heavy peak demands because of an extreme deficiency in the power supply. By temporarily disconnecting electrical circuits on a rotating basis, a majority of customers have power, inconvenience is minimized and a more serious widespread problem is averted. Each rotation is of a specific duration, usually no longer than a few hours, but it could take longer in some locations due to the manual nature of the operation.
  • Load Shedding
    An almost instantaneous cutting of power to customers because demand for electricity has outstripped supply.

FAQs

  • Q: How many times would you have to do this?

    Public appeals are one of several steps utilities can take in times of excess demand to safeguard the electric system. During periods of hot weather and when available generating capacity is limited, appeals may be issued whenever heavy electricity use reduces power reserves to unacceptably low levels.
