GLOSSARY

  • Load Shedding
    An almost instantaneous cutting of power to customers because demand for electricity has outstripped supply.
  • Power Watch
    Advisories to be announced when conditions are such that further steps to manage capacity could affect the public.
  • 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.
