GMA: ‘Heat Dome’ Will Bring Record Temps–And Risk Of Power Grid Collapse

On Good Morning America, ABC’s Sam Champion warned East Coast viewers it’s not just going to be insanely hot today, but–brace yourself–you might not have air conditioning to endure the heat. Champion says the monster heat wave is pushing power grids toward capacity as temperatures hover around 100 degrees and energy consumption strains the system. It’s called a “heat dome,” a shroud of high pressure that’s keeping millions of Americans stuck in a prison of hot, humid air–and a very real possibility of power failures.

As ABC News reports this morning, cities are bracing for the worst:

New York City’s Consolidated Edison reports that its system is at 93 percent capacity. The New York area will presumably break its record for power consumption today, and break the weekend power consumption record Saturday. The city can reportedly expect power outages to pop up during the next few days.

In Chicago, Commonwealth Edison reached an all-time peak usage milestone late Wednesday, while ISO New England – which covers six states from Connecticut to Maine — forecasts that demand Saturday will peak at 27,350 megawatts, putting it in the top 10 of usage days.

Intentional rolling blackouts have already begun in the Detroit area.
