NorthWestern Energy Submits FERC Dam Safety Follow-Up Plan
NorthWestern Energy filed a follow-up plan with the Federal Energy Regulatory Commission on dam safety findings at its Missouri-Madison Project, including panel replacements, updated operating procedures, revegetation monitoring, and bridge access limits for the Rainbow and Black Eagle Developments. The regulator response appears operationally contained and does not materially change near-term earnings, alongside reaffirmed 2026 guidance of $3.68–$3.83 per share.
