GLOSSARY

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

FAQs

  • Q: How much difference can turning out lights and appliances really make?

    It makes a big difference -- about 400 to 450 megawatts region-wide -- which in times of peak use is a very important part of the utilities efforts to safeguard the electric system. (A megawatt is one million watts and serves roughly 300 single homes.)
