What We Do For You

One of the smallest agencies in Montana state government, the Montana Public Service Commission (PSC) strives to ensure that ratepayers have continued access to utility services that are affordable, reliable, and sustainable for the long-term. In pursuit of this goal, the PSC regulates the rates and service quality for investor owned electric, natural gas, water, waste-water, and legacy telecommunication companies. It’s the PSC’s job to balance the interests of ratepayers who are concerned about utility rate increases, with the need to maintain a financially sound utility that is capable of providing reliable service. More Info
