- Who owns Monticello Nuclear Facility?

- Is this the same as Monticello Nuclear Facility LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Northern States Power Co - Minnesota here — not the project company that holds the asset.

This page shows only what EIA files, and does not assert a corporate structure it cannot see.
