- Financing summary: Dresden Unit 1 was developed under a 1955 fixed-price General Electric contract valued at $45 million. NRC material states that General Electric designed the plant and that $15 million of the contract price was contributed by Nuclear Power Group; a historical account states that Commonwealth Edison paid $30 million toward the contract and spent an additional $6 million outside it. These amounts describe Unit 1 construction financing and costs, not sale consideration. The October 2000 Unicom-PECO merger gave Unicom shareholders 0.875 Exelon shares and $3.00 in cash per Unicom share, but that was corporate merger consideration rather than a separately disclosed Dresden asset-sale price. — Friday Matinee Special Feature: Atomic Venture · confidence: medium

## Data quality

- The October 2000 ownership change is characterized as a Unicom/Commonwealth Edison corporate merger and Dresden license transfer to Exelon Generation, not as a separately priced asset sale. No standalone Dresden sale consideration was identified. A 2024 reference to a $350 million repowering investment concerns Constellation's renewable and wind fleet, including the Criterion Wind Project, rather than a Dresden nuclear repowering project; it is therefore excluded from the Dresden project-financing history. no separate expansion or repowering project for the Dresden nuclear units was established in the cited record.
