Electricity Prices in Mid-Atlantic States Fall as Demand Drops

Jan. 30 (Bloomberg) -- Spot wholesale electricity prices on PJM Interconnection LLC’s network fell as higher temperatures following days of frigid weather reduced demand on the largest U.S. power grid.

Prices also slid from the Northeast to Texas, and from California to the Midwest.

Consumption on the PJM network, which stretches from Washington to Chicago, dropped 6 percent to average 112,202 megawatts for the hour ended at 3 p.m. from the same time yesterday, grid data compiled by Bloomberg showed.

The temperature in Washington reached 33 degrees Fahrenheit (1 Celsius), 7 above yesterday’s high, at 3 p.m., according to AccuWeather Inc. in State College, Pennsylvania.

Spot prices at PJM’s benchmark Western hub, which includes deliveries to Washington, fell $102.79, or 70 percent, to average $43.77 a megawatt-hour for the hour ended at 3 p.m. from the same time yesterday, the grid data showed. Prices at the Eastern hub, which includes New Jersey, slid $107.34, or 67 percent, to average $52.51 a megawatt-hour.

PJM West on-peak power traded $26.36 below the Eastern hub, compared with a discount of $40.76 yesterday and a three-month average discount of $11 for PJM West.

New York City prices declined $173.72, or 50 percent, to average $174.72 a megawatt-hour at 3 p.m., while Boston prices fell $56.39, or 26 percent, to average $161.98 a megawatt-hour.

In Texas, prices at the North hub, which includes Dallas, and at the Houston hub declined $6.55, or 19 percent, to average $28.85 a megawatt-hour for the hour ended at 2 p.m. local time from the same time yesterday, the grid data show.
