In order to help protect the state's grid during a heat wave last week, the New York Independent System Operator (NYISO) notes that its demand response programs were a "key to successfully managing record energy demand."

According to the NYISO, the sixth day of a persistent heat wave produced record demand for electricity across New York. On Friday, the operator recorded an hourly average peak load of 33,956 MW, surpassing the previous record of 33,939 MW set on Aug. 2, 2006.

Other daily peak loads recorded in New York last week were 32,703 MW on Monday, 32,223 MW on Tuesday, 33,254 MW on Wednesday and 33,450 MW on Thursday.

Throughout the record-setting week, the NYISO says unprecedented levels of generator availability were experienced, with every bulk-power-producing asset within New York state in operation. However, the NYISO says managing electricity supply was only part of the equation.

Combined with statewide calls for voluntary reductions from the governor and local requests from utilities and power authorities, the NYISO has more than 1,200 MW of demand response resources to help manage demand during the highest demand periods.

The programs were deployed to relieve the historically congested areas of the lower Hudson Valley and southeastern New York every day last week and were activated statewide on Thursday and Friday.

“Due to the superb teamwork and coordination of New York’s transmission-owning utilities, electric generating companies, demand response resources, energy services providers and government agencies, we have successfully met record-high electric demand with sustained reliable operation of the bulk electric system,” says NYISO President and CEO Stephen G. Whitley.
