NYISO calls upon demand response to maintain reliability in frigid weather

The NYISO also encouraged consumers to help conserve electricity by adjusting thermostats to a comfortable but lower than normal setting if conditions permit

To support electric system reliability throughout the Northeast and Midwest regions as frigid weather conditions impact electricity use and power production, the New York Independent System Operator (NYISO) called for the activation of voluntary demand response programs (programs under which consumers reduce usage) statewide between 4 p.m. and 10 p.m. January 7.

The NYISO also encouraged consumers to help conserve electricity by adjusting thermostats to a comfortable but lower than normal setting if health conditions permit, refraining from using major electric appliances such as stoves, dishwashers and clothes dryers and turning off unnecessary electric lights and appliances from 4 p.m. to 10 p.m.

With extremely cold temperatures throughout the state and across much of the country, the NYISO anticipates the peak demand for electricity could rise to near-record levels for a winter day. The previous record winter peak demand of 25,541 MW was set on December 20, 2004.

Peak loads are measurements of the average total electric demand by consumers for a one-hour period. In recent years, the annual average hourly demand for electricity in New York State has been in the range of 18,000-19,000 MW.
