U.S. Northeast Power Prices Slump as Cooler Weather Quells Load


June 5 (Bloomberg Energy) -

U.S. Northeast spot power prices for energy delivered tomorrow fell today as cooler weather was expected to reduce air-cooling demand, traders said.

According to the PJM Interconnection LLC hub, electric demand across tomorrow's sixteen peak hours was expected to drop an average of 1,263 megawatts an hour, or nearly 3 percent from today's levels, to 41,263 megawatts an hour.

The Bloomberg peak day-ahead PJM power index fell $5.12 a megawatt-hour from yesterday to $34.40, a 12.9 percent decline.

"Prices are not going to be that strong tomorrow and Friday," said one northeast utility power trader. "We're expecting some pretty strong thunderstorms here, if that happens, that'll really cool things off."

According to Lexington, Massachusetts-based Meteorlogix, temperatures in Philadelphia were expected to reach a high of 79 degrees Fahrenheit tomorrow, down from today's forecast for a daily high of 90 degrees. Overnight temperatures will decline to 59 degrees, down from tonight's forecast high of 72 degrees.

Weather-related demand for tomorrow was forecast to decline as far north as the New England Independent System Operator, though not as severely as was expected in southern sections of the region.

New England utility power requirements for tomorrow's 16 peak hours were expected to average 16,301 megawatts an hour, 150 megawatts an hour less than today's projected load, according to estimates from the New England ISO.

The Bloomberg New England daily peak power index rose an average of 88 cents to $35.63, mostly amid reports that North Atlantic Energy Service Corp's 1,160-megawat Seabrook Unit 1 reactor was operating at reduced capacity.

The company said it reduced output at the unit to correct a heater drain problem. Traders said they expect the unit to resume full capacity soon as operators were increasing output by about 3 percent an hour. The company completed a planned refueling and maintenance outage on May 31.

In New York, west-to-east transmission congestion problems persist on the Central East Gathering System, traders said.

The western New York peak power price at Zone A trailed peak power values in New York City by $28.97 a megawatt-hour. The Bloomberg eastern New York index at Zone G fell $6.27, or 13.6 percent from yesterday, to $40.00 a megawatt-hour. -Brian Whary
