American Electric Power is reviewing exits from PJM and SPP over slow generation…
Brief
U.S. utility sector headlines (Utility Dive, May 6, 2026) center on grid strain from rapid large-load growth and the evolving role of nuclear and renewables. American Electric Power is weighing leaving PJM or SPP because slow generation interconnection is constraining its response to contracts for 63 GW of new large load by 2030. Xcel’s tariff agreement with Google is being positioned by CEO Bob Frenzel as a repeatable model to attract hyperscalers while accelerating renewables. TVA reports nuclear now supplies 41% of its power and interim CEO Mike Skaggs seeks clarity on new nuclear technologies and federal coordination. Duke added 2.7 GW of data-center contracts in Q1 (total 7.6 GW, ~66% under construction) and maintained a $103 billion capital plan. Meanwhile, NERC’s Level 3 alert requires seven prescribed actions by Aug. 3, 2026 to mitigate immediate risks from computational load losses.
Why it matters
American Electric Power is reviewing exits from PJM and SPP over slow generation interconnection amid surging customer demand; AEP utilities have contracts for 63 GW of new large load across their multistate footprint by 2030 (Utility Dive, May 6, 2026).
Key details
- Xcel Energy’s CEO Bob Frenzel said the company’s tariff deal with Google creates a template for courting large loads while doubling down on renewables as the primary supply strategy.
- Tennessee Valley Authority generation is now 41% nuclear; interim CEO Mike Skaggs said TVA will clarify its position on new nuclear technologies and coordinate with the federal administration and its board on future paths.
- Duke Energy added 2.7 GW of contracted data center load in Q1 2026, bringing total executed data center agreements to 7.6 GW — nearly two-thirds of which are already under construction — while keeping its $103 billion capital plan unchanged from 2025.
- NERC issued a Level 3 alert calling computational/data center loads an “immediate risk,” mandating seven actions for certain grid participants by Aug. 3, 2026 to address potential data center load losses.
