Constellation Energy

Type: Company — Independent Power Producer / Nuclear Operator

Constellation Energy is the largest operator of nuclear power plants in the United States, with a fleet of approximately 24 GW across 21 reactors at 12 stations. Spun out of Exelon in February 2022, Constellation operates exclusively in competitive wholesale markets — making it the purest nuclear IPP in the US and the prime beneficiary of AI-driven nuclear demand.

Strategic Position in AI Power

Constellation is the central corporate entity in the hyperscaler nuclear PPA wave:

• Microsoft/Crane (TMI restart): 20-year PPA for all output from the 835 MW Crane Clean Energy Center (formerly Three Mile Island Unit 1, closed 2019). FERC granted a waiver June 1, 2026 to transfer 760 MW of Capacity Interconnection Rights from Eddystone; NRC restart decision expected mid-2026; restart target 2027. Water intake permit from Susquehanna River Basin Commission still pending (73.2M gallons/day).
• Meta/Clinton Power Station: 20-year PPA for power from Clinton Power Station in Illinois, beginning 2027.
• Life extension: Constellation is pursuing 80-year license renewals across its fleet to maximize the value of low-cost, permitted nuclear assets.

Anchor-deal context (new source): The Constellation↔Microsoft 20-year PPA to restart Three Mile Island Unit 1 (Pennsylvania) was signed in Sep 2023 — the opening deal of the hyperscaler nuclear-procurement rush (restart → first corporate SMR PPAs → multi-GW advanced-reactor deals). Evidence: moderate (multi-source synthesis, hyperscaler-nuclear-procurement)

Key Business Facts

• Fleet: ~24 GW, 21 reactors, ~800-900 TWh/year generation
• Primary markets: PJM (Mid-Atlantic/Midwest), MISO, NYISO
• Operating cost advantage: existing nuclear costs ~$30-50/MWh; long-term PPAs at $80-120/MWh = structural margin expansion for 20 years
• Westinghouse: not owned by Constellation (owned by Brookfield/Cameco JV), but Constellation uses Westinghouse fuel and services

Outstanding Questions

• When does the Crane/TMI restart receive NRC approval and water intake permit? (2026 decisions are gate-critical for 2027 restart)
• How much of the existing fleet will Constellation commit to additional long-term PPAs vs keep on merchant exposure?
• Does Constellation acquire any new nuclear assets (e.g., Palisades if Holtec restart struggles)?
