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 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.
  • Power Watch
    Advisories to be announced when conditions are such that further steps to manage capacity could affect the public.

FAQs

  • Q: Could this happen to customers more than once?

    Yes, but it is unlikely. When load shedding occurs, the electric companies would disconnect as many customers as necessary and then restore them when rolling blackouts begin. Rolling blackouts disconnect blocks of customers in rotating sequences and would continue until the utilities are able to bring supply and demand back in balance.
