Summer’s last blast causes power price surge in East

While many people think of Labor Day as the unofficial end of summer, the air conditioning season clearly hasn’t ended on the power grid for much of the East Coast.

New England had the highest reported spot power price for delivery Sept. 11 at $180.72/MWh. The New England spot power price was up more than 219% over the prior day, according to Energy Information Administration (EIA) figures.

The Mid-Atlantic and New York City were also feeling the heat with spot power prices at $103.37 and $97.32 respectively.

By comparison, the highest listed spot price in EIA’s other seven reporting regions was $51.84 in the Midwest.

The Boston forecast called for a high temperature of about 91 degrees. One weather service said it is rare for the Boston temperature to rise above 82 degrees at this time of year. The National Weather Service (NWS) has issued a heat advisory for eastern Massachusetts and southern New Hampshire, saying the high humidity could make it feel hotter than 100 degrees.

The Washington, D.C. forecast predicted a high of 93 degrees and a 95-degree high was forecast for New York City. That’s pretty steamy for football season.

Meanwhile, the NWS said widespread showers and thunderstorms will continue across much of the Southwest and Central Rockies on Sept. 11. As a result, flash flooding will be a serious threat in these regions.
