Signal notes
Operator "Atlas Power" has no operators.yml entry — needs one before the operator field can be set. Reported operating in Butte since 2019, hence status operational. Capacity: NorthWestern Energy to supply 75 MW beginning 2026, with up to another 75 MW over 3-5 years (expansion not yet firm, so capacity_mw reflects the initial 75 MW). Single source (Daily Montanan) → medium confidence.
