Live News

Published May 3, 2026: On a recent episode of the *Prof G Markets* podcast, veteran data center infrastructure executive John Perella revealed a previously unreported near-miss grid event in Virginia that nearly triggered widespread rolling blackouts. Nine regional data centers went offline and switched to backup power during an unplanned grid disturbance; when grid power was restored, the absence of expected data center load caused a grid over-frequency event that came within 0.3 Hz of automati Southern Company (SO) - AI Data Center Gigawatt Expansion Poses Material Grid Stability, Regulatory and Demand RisksObserving correlations between markets can reveal hidden opportunities.

Key Highlights

Several core takeaways carry material implications for utility investors, particularly holders of SO: First, grid stability risk from uncoordinated AI buildouts is no longer theoretical, with the Virginia near-miss demonstrating that even small mismatches between data center load and grid supply can trigger cascading systemic events, raising the likelihood of near-term federal regulatory intervention.

Expert Insights

From a fundamental valuation perspective, SO’s current share price largely prices in the upside of 12.9% wholesale sales growth from AI demand, but fails to account for three material downside risks that support our bearish 12-month outlook. First, regulatory risk: The Virginia near-miss has already prompted the DOE to draft proposed rules that would extend data center interconnection approval timelines by an estimated 18 months for projects over 100 MW, a change that would delay 7 of the 12 planned AI data center hookups in SO’s Southeastern service territory, per our analysis. We estimate this would cut SO’s projected 6.8% annual wholesale revenue growth through 2028 by 270 basis points, leading to a 6.2% downside to consensus FY27 EPS estimates. Second, demand forecasting risk: Perella’s observation that most interconnection queue projects are undercapitalized means SO’s long-term demand projections, which assume 9 GW of new AI data center load by 2030, may be overstated by as much as 40%. If only 5.4 GW of that projected load comes online, SO’s planned $14 billion in grid upgrade capex for AI interconnection would leave roughly $3.2 billion in stranded assets, pressuring return on equity by an estimated 120 basis points. Third, operational risk: Should a grid stability event tied to AI data center load occur in SO’s service territory, the company would face mandatory regulatory fines, customer restitution costs, and required grid hardening spending that could add up to $1.8 billion in unplanned capex over three years, per utility sector precedent. While SO could mitigate these risks by partnering with hyperscalers on demand response and load-shifting programs similar to NextEra’s NVIDIA collaboration, management has not disclosed any such strategic partnerships on recent earnings calls, leaving the company exposed to near-term downside. We maintain a bearish rating on SO with a 12-month price target of $62, representing a 7.1% downside from its May 2, 2026 closing price of $66.75.
