Real-time wholesale electricity prices in Dominion Energy’s Virginia service area surged past $1,800 per megawatt-hour early Sunday, pushed by Winter Storm Fern and demand that outstripped forecasts in the nation’s busiest data-center hub. That’s up from roughly $200 just a day before. PJM Interconnection expects winter demand to hit a peak of 147.2 gigawatts on Tuesday, breaking the previous January 2025 record of 143.7 GW. Data from PJM showed Dominion’s load running about 5% higher than forecast Sunday morning.
