As people use more energy to cool their homes during increasing heat waves, one thing utilities are trying is to reward homes for reduced energy use during peak times. [Wall Street Journal]
As residents of the East Coast cranked up their air conditioners in last week’s stifling heat wave, utility officials turned not only to every available power plant but also to increasingly popular “demand response” programs that reward customers for cutting power use at peak times.
In the energy world, where units of electricity are measured in “megawatts” or millions of watts, these peak-time conservation efforts are said to provide valuable “negawatts” that help cushion the electric grid against surges in demand that can send prices soaring and even cause outages.
In New York, for example, a program run by the state’s grid operator produced energy savings on Friday equivalent to the output of two large power plants. Electricity use that day peaked at 33,955 megawatts, beating the prior state record set Aug. 2, 2006, of 33,939 megawatts.
The program was crucial, said Tom Rumsey, vice president of external affairs at the New York Independent System Operator, which manages power flows in the state. “Every generating asset we had was working all week and we were just a couple hundred megawatts away” from running dangerously low on power.
