Rolling outages possible during extreme weather

You hear the term rolling blackout or scheduled power outage, but what is it exactly? A rolling blackout, also referred to as rotational load shedding or feeder rotation, is an intentionally-engineered electrical power shutdown in which electricity delivery is stopped for non-overlapping periods of time over different parts of the distribution region. This helps bring the supply of and demand for electricity back into balance and prevent the possibility of longer, more widespread outages.
