Senate Bill No. introduced by A. Olsen mandates that all public utilities in Montana develop a comprehensive plan by May 30, 2026, detailing their strategies for procuring 100% of their retail energy sales from renewable resources, including potential hydroelectric options. Additionally, the plan must address the challenges and timelines associated with reducing greenhouse gas emissions, in alignment with the state's constitutional obligation to maintain a clean and healthful environment.

The bill also requires that each public utility submit their plan to the Energy and Telecommunications Interim Committee by June 1, 2026. This committee is tasked with reviewing the submitted plans, inviting public comments, and providing recommendations to the 70th legislature regarding the outlined options and challenges. The act is set to take effect immediately upon passage and approval.
