Key Points
- The
Montana Public Service Commission (PSC) approved a temporary reduction in
electric rates for NorthWestern Energy customers, effective July 2, 2025. - NorthWestern
Energy had previously implemented a rate hike of up to 17% without PSC
approval in May 2025, citing state law that allows such action if the PSC
does not decide within nine months. - The
newly approved rate reflects a 4.2% increase, down from the initially
proposed 8.3% hike, following a settlement involving key stakeholders such
as the Montana Consumer Counsel and the Montana Large Customer Group. - For a
typical residential customer using 750 kWh per month, the temporary change
means a monthly bill reduction of $4.48 compared to the May 23 rate. - The
PSC’s decision passed with a narrow 3-2 vote and is subject to further
review as the larger rate case continues. - If the
PSC’s final decision results in a lower rate than the current temporary
rate, customers will receive a refund with interest. - The
Yellowstone County Generating Station (YCGS) methane gas plant near
Laurel, Montana, is a major factor in the ongoing rate case, with costs
and prudency under scrutiny. - The
rate case remains ongoing, with briefs due in July and August and a final
PSC order expected later in 2025. - NorthWestern
Energy emphasizes the complexity of delivering reliable energy and the
need for transparent communication with customers. - Consumer
advocates and some customers have criticized NorthWestern Energy’s use of
the self-implementation statute and lack of advance notice for the May
rate hike.
The Montana’s largest utility, NorthWestern Energy, will
temporarily lower electric rates for its customers following a contentious
regulatory battle and public outcry over an unapproved rate hike earlier this
year. The move comes as the Montana Public Service Commission (PSC) seeks to
balance consumer protection with the utility’s financial needs, and as the
state’s energy landscape faces scrutiny over new infrastructure investments and
rising costs.
Why Did NorthWestern Energy Lower Rates for Montana
Customers?
As reported by the editorial team at KXLF, the Montana
Public Service Commission (PSC) approved a temporary rate reduction for
NorthWestern Energy customers after months of examination, including an
eight-day evidentiary hearing. The process began when NorthWestern Energy
filed for an 8.3% rate increase in July 2024, citing increased costs for
electric service delivery and the construction of the Yellowstone County
Generating Station (YCGS), a new methane gas plant near Laurel, Montana.
In May 2025, NorthWestern Energy implemented a 17% rate hike
without PSC approval, leveraging a Montana statute that allows utilities to
self-implement new rates if the PSC does not act within nine months. This
move sparked concern among customers and regulators alike. As Amanda Eggert of
Montana Free Press reported, NorthWestern Energy’s action was unprecedented in
Montana and affected all customer classes, including residential, commercial,
and industrial users.
How Was the New Rate Determined?
According to NBC Montana, after extensive hearings and
negotiations, NorthWestern Energy agreed to a settlement with several key
stakeholders, including the Montana Consumer Counsel, the Montana Large
Customer Group, the Federal Executive Agencies, and Walmart Inc.. The
settlement reduced the proposed rate hike from 8.3% to 4.2%, which the PSC
approved with a 3-2 vote.
The new temporary rate took effect July 2, 2025, and will
remain in place until the PSC issues a final order later this year. For a
typical residential customer using 750 kilowatt-hours per month, this means a
monthly bill reduction of $4.48 compared to the temporary rate that began on
May 23, 2025.
What Did the Montana Public Service Commission Say?
As quoted by Alana Lake, Executive Director of the PSC, in
KXLF’s coverage,
“This Commission and staff take seriously the PSC’s mandate to
protect the public interest while balancing those of the utility. After careful
evaluation of the law and arguments presented by all sides, the Commission’s
action this week will prevent ongoing unnecessary rate hikes for Montana
families and businesses”.
PSC President James Brown said in a November 2024 statement,
“With today’s outcome, the Commission has once again satisfied its obligation
to customers of NorthWestern Energy to ensure utility rates are fair and
justified. The entire Commission recognizes that Montanans have been facing
historically high prices for everything from housing to health care, food to
insurance, diesel fuel and gasoline for the last four years. Going into the
holiday season this year, electricity bills will be going down for NorthWestern’s
electricity customers in the interim period, more than offsetting a smaller
increase in their natural gas bills”.
What Was NorthWestern Energy’s Response?
In a July 2, 2025, press release, NorthWestern Energy
emphasized its commitment to reliability and transparency:
“Providing reliable
energy 24/7 is complex, and customers deserve accurate and transparent
information about their electric rates. Our investment decisions focus on
maintaining reliability and safety, while keeping bills as low as possible”.
The company also clarified that if the PSC’s final decision
results in a lower rate than what’s currently being charged, customers will
receive a refund for the difference, with interest. NorthWestern Energy
encouraged customers struggling with bills to reach out for assistance and
noted that energy rate adjustments are communicated through customer bills.
What Do Consumer Advocates and Customers Say?
The Montana Environmental Information Center (MEIC) has been
a vocal critic of NorthWestern’s rate practices, particularly regarding the
costs associated with the YCGS methane gas plant. As reported by MEIC, the
plant’s construction cost NorthWestern upwards of $320 million, with ratepayers
potentially on the hook for over $2.3 billion. MEIC argued that the company’s
claims of $58 million in annual market savings are unsubstantiated and
insufficient to justify the investment.
MEIC was the only intervenor to file a formal objection to
NorthWestern’s interim rate increase, leading to the PSC’s rejection of a $58
million “bridge rate” for YCGS. This decision resulted in a $7.92 monthly
saving for electric customers using 750 kWh.
Customers expressed frustration with NorthWestern’s use of
the self-implementation statute and lack of advance notice for the May rate
hike. As reported by KXLF, customer Ryan Hessler said,
“Just the concept of
raising it makes sense. You need to do that at some point, but doing it without
telling people, without any sort of public comment… It’s not very good optics
for a company to do that out of nowhere, especially for a significant increase
that could really affect people”.
What Is the Immediate Impact on Bills?
According to NorthWestern Energy’s official statement, the
temporary rate reduction will lower the typical residential customer’s bill by
$4.48 per month compared to the rate in effect since May 23, 2025. The
PSC’s earlier decision in November 2024 had already resulted in a 7.24% interim
reduction, saving customers about $7.96 per month.
However, as reported by the Montana Free Press and other
outlets, customers have seen significant volatility in their bills over the
past year, with the average residential customer paying $127.16 in July 2025,
up from $101.14 in May 2024—a more than 25% increase in just two months.
Will There Be Further Changes?
The rate case is ongoing, with NorthWestern Energy required
to submit an opening brief by July 21, 2025. Intervenors will file response
briefs by August 11, and NorthWestern will reply by August 26. The PSC is
expected to issue a final order later in 2025, which could result in further
adjustments to customer rates.
If the final approved rate is lower than the temporary rate,
NorthWestern Energy will refund customers for any overcharges, with interest,
as confirmed by both the company and the PSC.
What Role Did the Yellowstone County Generating Station
Play?
The Yellowstone County Generating Station, a methane gas
plant near Laurel, Montana, has been at the center of the rate case. As
detailed by MEIC, the plant’s construction cost and projected impact on rates
have drawn criticism from consumer advocates, who argue that the investment is
risky and may not deliver promised savings.
The PSC denied NorthWestern’s request for a $58 million
“bridge rate” to recover costs associated with the plant, stating that the
prudency of the investment remains under review.
What’s Next for NorthWestern Energy and Its Customers?
The PSC will continue its analysis of the evidence and
arguments presented by all parties before issuing a final decision. The outcome
will determine whether the temporary rate remains in place, is further reduced,
or is increased. Stakeholders, including consumer advocates and large
customers, will have the opportunity to influence the final order through their
briefs and public comments.
What Should Customers Do in the Meantime?
NorthWestern Energy advises customers to monitor their bills
for updates and to contact the company if they have concerns about payment. The
utility offers billing and payment options to assist those experiencing
financial hardship.
In summary, the temporary rate reduction for NorthWestern
Energy customers in Montana is the result of a complex regulatory process
involving utility requests, stakeholder negotiations, and public scrutiny. The
final impact on customer bills will depend on the outcome of the ongoing PSC
review, with further changes possible before the end of 2025.
