Myths or Facts? Understand The Facts Behind NorthWestern’s Rate Review
There's a lot of talk about NorthWestern Energy’s proposed rate changes — but not all of it is true. It’s time to separate fact from fiction and understand why these changes are crucial for ensuring reliable energy for our customers and avoiding an energy crisis.
You've Heard the Myths
Now get the facts about NorthWestern's rate review in Montana.
On Nov. 19, 2025, the Montana Public Service Commission (PSC) voted on our July 2024 request to update our electric and natural gas rates. A public hearing on that request was held in June. The final order to implement the Montana PSC action is expected to be issued by the PSC by Dec. 24, 2025.
Myth:
NorthWestern Energy rates are increasing 26% for residential customers.
Fact:
The new electric rate approved by the Montana Public Service Commission begins Feb. 1. A monthly bill for a residential electric customer using 750 kilowatt hours per month will decrease $2.16, or 1.83% compared to typical bill with January rates. Compared to a typical bill in July 2024, which is when the request for a Regulatory Rate Review was filed, a monthly bill for a residential electric customer will increase $5.89, or 5.35%.
The new natural gas rate approved by the Montana Public Service Commission begins Feb. 1. A monthly bill for a residential natural gas customer using 65 therms per month will increase $1.62, or 2.92% compared to a typical bill with January rates. Compared to a typical bill in July 2024, which is when the request for a Regulatory Rate Review was files, a monthly bill for a residential natural gas customers will increase $5.22, or 10.06%.
Myth:
NorthWestern Energy’s residential customers’ interests were not represented in rate reviews.
Fact:
The Montana Consumer Counsel advocates for consumers in hearings before the Montana Public Service Commission and did so in NorthWestern Energy’s regulatory rate review. The Montana Consumer Counsel is a party in the partial electric rate settlement and the full natural gas rate settlement.
Myth:
NorthWestern Energy is investing in natural gas and coal generation in Montana instead of resources that will be economically viable for the long term.
Fact:
NorthWestern Energy needs more resources that can generate power on demand, 24/7, located in Montana and dedicated to serve Montanans to meet our responsibility to provide our customers with reliable energy service, keep them safe in all weather conditions and avoid an energy crisis.
NorthWestern Energy’s Montana electricity supply mix includes 33% carbon-free hydro and about 24% renewable energy generation, including wind and solar. Renewable energy is used when available, but since we can’t control the wind or sun, our power supply needs reliable backup resources to meet demand. Today, those resources are existing coal and new natural gas plants. That is why we have agreed to take on a larger share of the Colstrip Plant and that is why we made the investment to build the Yellowstone County Generating Station.
Myth:
NorthWestern Energy’s residential customers are bearing the heaviest costs of the newly approved rates.
Fact:
Cost of service studies show that some customer classes subsidize others. The large industrial customers are still subsidizing residential customers.
Myth:
NorthWestern Energy’s Montana rates are the highest in the region.
Fact:
NorthWestern Energy rates are below the national average for both electric and natural gas in Montana, in fact, natural gas is over 40 percent lower than the national average. There are 113 electric and natural gas energy service providers in the United States going through regulatory rate reviews right now.
