What are "rolling blackouts"?
Rolling blackouts are temporary interruption of electrical service. NYISO will implement rolling blackout only if and when New York's electrical system is unable to meet heavy peak demands because of an extreme deficiency in 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.
