New York City Power Jumps to 8-Year High as Temperatures Decline

Jan. 23 (Bloomberg) -- Wholesale electricity jumped in the Northeast, reaching an eight-year high in New York, as freezing weather spurred demand while heating-fuel costs increased.

Below-normal temperatures that swept into the region at the start of this week dropped further today, according to AccuWeather Inc. in State College, Pennsylvania.

Natural gas for delivery in Manhattan rose to a five-year high while prices in New England reached the highest in nine years. Gas-fired plants accounted for 51 percent of power generation in New England as of 1:50 p.m., according to ISO New England, the region’s grid operator.

“Judging from how firm power prices look here, it’s a little bit colder than people were expecting,” said Tom Hahn, vice president of U.S. power derivatives at brokerage ICAP Energy LLC in Durham, North Carolina. “These are the highest prices we’ve seen in a while.”

Real-time on-peak spot wholesale power in New York City averaged $469.69 a megawatt-hour as of 2:13 p.m., heading for the highest average for any day since at least January 2005, according to New York Independent System Operator Inc. data compiled by Bloomberg. On-peak hours are between 7 a.m. and 11 p.m., according to the grid operator.

New England averaged $214.98 a megawatt-hour as of 2:13 p.m., heading for the highest daily on-peak average since July 22, 2011, according to ISO New England Inc. data compiled by Bloomberg.

Low Temperatures

The temperature in Manhattan was 18 degrees Fahrenheit (minus 9 Celsius) at 5:48 p.m., down from the average low for the day of 27 degrees, AccuWeather said. Boston was at 14 degrees versus the normal low of 22 for the day.

Demand in New York City may peak at 7,246 megawatts in the hour starting at 5 p.m., NYISO data show. Power consumption peaked at 7,423 megawatts at 6:05 p.m. yesterday, 4.8 percent higher than the forecast for the day.

Total demand across the New York state grid will be close to 24,000 megawatts today, about 9,000 megawatts below summer peak demand, said Kenneth Klapp, a spokesman for the grid operator in Rensselaer, New York. “That’s high,” he said. Electricity consumption is highest during the summer because of air-conditioner use.

Power demand from Maine to Connecticut was 18,500 megawatts as of 12:10 p.m. and may peak at 20,800 megawatts at 6:30 p.m. today, according to ISO New England Inc. Consumption yesterday peaked at 19,817 megawatts.

Klapp and Lacey Ryan, a spokeswoman for ISO New England in Holyoke, Massachusetts, both said power prices during this cold snap are also being driven higher by generation costs.

Iroquois Zone 2 gas outside of New York City rose $11.1247, or 51 percent, to $33.1235 per million British thermal units on the Intercontinental Exchange, the highest price since January 2008. Spot gas at the Algonquin City Gates for delivery to locations including Boston rose $10.0578 per million Btu, or 47 percent, to $31.2684, the highest since January 2004.
