New York relying much less on Indian Point for energy
Electricity Fact Sheet
Con Ed reports that the energy load drops to that level between 3 AM and 5 AM, Sunday mornings, about three times in the late spring and three times in the early fall when it is too cool for air conditioning, too warm for electric heaters, and the city sleeps. During those isolated periods the 2,000 megawatts from Indian Point - if it were all used in the region - would comprise 40%.
If it were legitimate to use the exception, when most electrical systems were turned off, it would also be legitimate to claim that the most consistent power source in the region is the Eveready Bunny, whose batteries powered flashlights throughout the New York City/ Westchester County grid during the 2003 Blackout.
