Intense Heat Strains Power Grids for 100 Million North Americans
Power grids serving more than 100 million North Americans are bracing for a demand surge as unseasonable heat strains electrical equipment scheduled for repairs.
Unseasonable heat is placing a strain on power grids serving over 100 million North Americans, according to reports. Some areas are experiencing temperatures more than 20 degrees above normal, with triple-digit heat forecast in the South through Sunday. St. Louis is expected to reach a sweltering 99F and is under a heat advisory.
This heat is occurring just as power plants were set to undergo maintenance, exacerbating the strain on the grids. The Midcontinent Independent System Operator reported 51 gigawatts of generation outages, while the PJM Interconnection LLC grid, which covers Chicago, Washington DC, and Virginia's Data Center Alley, expects electricity usage to surpass 132 gigawatts.
PJM officials have requested a waiver of emissions rules to allow plants to operate at full capacity. Spot power prices in the largest US grid have jumped above $4,300 per megawatt-hour. Aging generating stations are facing increased stress due to the prolonged heat and growing demand from industries and data centers.
