SB188

Revising solar energy policy laws

Vetoed·6/9/25

Montana SB188 establishes the Montana Solar Shares Act, regulating shared solar energy facilities and on-bill credits for subscribing customers.

Montana SB188, known as the Montana Solar Shares Act, sets forth regulations for shared solar energy facilities, which are solar energy facilities with outputs shared through subscriptions. These facilities must be interconnected to a public utility's distribution system, have a generating capacity between 50 kilowatts and 5 megawatts, and be located within the service territory of the public utility. The act mandates that public utilities grant on-bill credits to subscribing customers for their proportion of the facility's electricity generation.
