Summary
Summary of the 8-K filed September 20, 2024. Cited figures are marked; the original filing is the authoritative source.
On September 20, 2024, Constellation Energy (CEG) disclosed a 20-year power purchase agreement with Microsoft, its largest-ever PPA, to restart Three Mile Island Unit 1, which will be renamed the Crane Clean Energy Center (CCEC).
Microsoft will purchase the plant's full output (about 835 MW) to help match the power its PJM data centers use with carbon-free energy. The plant was retired in 2019 for economic reasons. Restart is targeted for 2028, and the company plans to pursue a license renewal extending operations to at least 2054.
The restart is contingent on NRC approval following a comprehensive safety and environmental review, along with state and local permits, a PJM interconnection process, and FERC approval for grid synchronization. Management estimates about $1.6 billiona of capex to be deployed for Crane through 2028, with annual spend peaking around $625 million in 2026. Management said the project raises its base EPS growth rate from at least 10% to at least 13% annually over 2024 to 2030, exceeds its double-digit unlevered return threshold, and meets eligibility for the 45Y clean energy production tax credit.
For investors, the key takeaways are the long-term contracted revenue from a creditworthy counterparty, a meaningful uplift to earnings growth, and a sizable but manageable capital commitment. The principal risks are regulatory timing, since NRC approval is the gating item, along with execution risk on a plant that has been idle for five years and the project's dependence on the continued availability of federal tax credits. The filing contains no quantified contract revenue, so the financial impact can be assessed only through management's EPS and capex guidance.

03—Questions
Frequently Asked Questions
How large is the Microsoft agreement and what does it cover?
It is a 20-year fixed-price offtake agreement for the plant's full output, about 835 MW, which management says provides roughly 7 million MWh of new supply annually. The filing does not disclose the contract's dollar value.
What is the expected earnings impact for shareholders?
Management says the project raises Constellation's base EPS growth rate from at least 10% to at least 13% annually from 2024 through 2030. These are management projections, not guaranteed outcomes.
What could delay or derail the restart?
Key gating items include NRC approval of the restart after a comprehensive safety and environmental review, state and local permits, PJM interconnection studies, and FERC approval to sync to the grid. The NRC process is estimated at 18–24 months, and the plant has been shut since 2019, so restoration and execution risk are significant.
How much capital will Constellation need to invest?
The investor presentation shows approximately $1.6 billion of capex for Crane, spread over 2024–2028 with about $75 million in 2024, $350 million in 2025, $625 million in 2026, $425 million in 2027, and $125 million in 2028. This spending is included in the company's capital allocation plans.
Does the project depend on tax incentives?
The company says the project meets eligibility criteria for the 45Y clean energy production tax credit. Because this credit is federal, changes to tax policy could affect the project's economics, though the filing does not quantify that sensitivity.
