Data Center Alley Briefly Unplugs, Rattling Dominion's Grid
D sits 27% above its 52-week low of $55.854 on light trading volume (0.2× avg).
Summary
A transmission line fault in northern Virginia caused data centers to disconnect ~3 GW of demand, destabilizing the grid for several minutes. Dominion Energy confirmed the fault and said data centers switched to backup power, with operations returning to normal quickly. The incident underscores the operational risks of rapid data center load growth in Dominion's service territory, which is central to the company's growth narrative. This follows the May 2026 merger announcement with NextEra Energy, where data center demand was a key driver. The event may attract regulatory scrutiny over grid reliability and ride-through requirements for large customers.
At the time of this announcement, D was trading at $71.04 on NYSE in the Energy & Transportation sector, with a market capitalization of approximately $62.5B. The 52-week trading range was $55.85 to $72.99. This news item was assessed with negative market sentiment and an importance score of 7 out of 10. Source: Dow Jones Newswires.
