Investment Thesis
Constellation is the largest nuclear power operator in the US — 21 reactors, 10 sites, producing 10% of US carbon-free electricity. The Microsoft deal to restart Three Mile Island Unit 1 (2028) proved that hyperscalers will pay a significant premium for 24/7 carbon-free baseload. Constellation is the most direct listed bet on nuclear renaissance driven by AI power demand.
Key Drivers
- Microsoft Power Purchase Agreement: 20-year PPA for Crane Clean Energy Center (Three Mile Island restart) sets the template for hyperscaler-nuclear partnerships.
- Existing Fleet Value: Nuclear plants have sunk costs paid; marginal production cost is $20–30/MWh vs $80+ for gas peakers.
- Policy Tailwind: IRA nuclear production tax credits and bipartisan support for nuclear extension.
Risk Factors
- Regulatory Licence Extensions: Each plant requires NRC approval for life extension.
- Grid Reliability Costs: Maintenance surprises at ageing plants create one-time cost hits.
