Montana Electric Bill Rates
We want you to have the facts
We’re committed to keeping you informed about your energy rates and helping you understand what’s changing.
On Oct. 1, the Supply Rate on your electric bill will decrease. For a typical residential customer using 750 kilowatt-hours, this means your monthly bill will decrease by $8.57 or 6.58%.
Your electric bill includes several rate components:
- Supply Rate: The cost of the electricity used in your home or business. This rate is adjusted quarterly and is also reviewed annually through a "true-up" process that aligns the amount collected from customers with the actual cost of electricity over the previous 12 months. The Supply Rate is the portion of your bill that will change on Oct. 1.
- Delivery Rate: This covers the cost of delivering electricity to your home or business. This rate is not changing.
- State and Local Taxes: the cost of property taxes on powerlines, pipelines, generation facilities and other infrastructure that provide energy service to our customers in Montana. These costs are implemented by the State of Montana and flow through to customer bills.
You can track your energy use and compare bills anytime in My Energy Account. You’ll also find helpful tips to manage your energy costs.
We work every day to provide the safe, reliable energy service our customers depend on while keeping rates as affordable as possible.
Strategic investments in our energy system enable us to meet your energy needs today and prepare for tomorrow.
If you’re having trouble paying your bill, please don’t wait—reach out to us. We offer billing and payment options that may help.
Looking ahead:
- The electric Supply Rate and State and Local Taxes will be adjusted next on Jan. 1, 2027.
