New York May Reach 100 Degrees as Power Use Sets a RecordBrian K. Sullivan and Jim Polson
Temperatures in New York City, where electricity consumption hit an all-time high, will soar close to 100 degrees Fahrenheit (38 Celsius) again today and humidity will make the weather feel more like 110, which may spur electricity consumption an all-time high for the state.
Yesterday, a new daily temperature record of 100 degrees was set at John F. Kennedy International Airport, breaking the mark of 96 set last year, according to the National Weather Service. The temperature reached 101 at Newark Liberty airport, 100 at La Guardia airport and 98 at Central Park.
Those levels may be reached again today, said Lauren Nash, a weather service meteorologist in Upton, New York.
“The big story today is going to be the excessive heat warning,” Nash said by telephone. “The temperature could hit 101, 102 in some areas.”
Heat warnings and advisories are in place from Maine to Iowa and across southern Canada as the heat wave enters its sixth day in many places. The temperatures have spurred energy demand as people in the high-population areas of the eastern U.S. and Canada have turned to air conditioning to cool.
Electricity consumption in New York City hit a record 13,214 megawatts, enough for 10.5 million homes on an average day, at 2 p.m., Chris Olert, a spokesman for utility Consolidated Edison said today in a telephone interview. The previous record was set July 22, 2011, he said.
New York’s grid operator forecast it may also set a statewide record peak consumption today of 34,600 megawatts, enough for more than 27 million homes on an average day, according to U.S. Energy Department estimates. All available power plants in the state are running, the New York Independent System Operator Inc. said in a statement.
Actual consumption may be less because the grid operator triggered conservation incentives that may curtail 1,200 megawatts, said Ken Klapp, a spokesman for the grid operator in Rensselaer, New York. The state record for peak power use, 33,939 megawatts, was set Aug. 2, 2006.
PJM Interconnection LLC, operator of the largest U.S. high-voltage network, forecast peak electricity consumption will decline 0.7 percent from yesterday’s use of 158,156 megawatts, enough for 126.5 million homes on an average day.
Today’s high temperature in Boston may reach 101, according to the weather service. In Philadelphia, it may peak at 99; in Washington 97; in Chicago 98; and 93 in Detroit, according to the weather service.
Toronto may reach 95 today and Montreal near 90, according to Environment Canada.
“Today is the final and probably peak heat day for the Eastern heat event with mid- to upper 90s widespread, but also some 100 Fahrenheit hits again in spots like New York and Boston,” said Matt Rogers, president of the Commodity Weather Group LLC in Bethesda, Maryland. “Rains increase this weekend in the East with a cool front arrival.”
Environment Canada issued severe thunderstorm watches across southern Ontario and Quebec as the cold front arrives. Those storms are expected to move south into the U.S. tomorrow, according to the Storm Prediction Center in Norman, Oklahoma.
