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 $11.08 or 9%.
Your electric bill includes two types of rates:
- Supply Rate – This is the cost of the electricity itself. It changes quarterly based on market prices. This is the rate that will change Oct. 1.
- Delivery Rate – This covers the cost of delivering electricity to your home or business. This rate has not changed.
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’re working hard to keep your service reliable and your bills as low as possible. Our electric reliability is better than the industry average, and our rates are below the national average. We carefully manage costs and invest in sustainable energy systems to serve you now and into the future.
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 will be adjusted next on Jan. 1, 2026.
- In July 2024, we submitted a request to update Delivery Rates. A public hearing concluded on June 18, 2025, and we expect a final decision from the PSC in fall 2025.
If you're a commercial, industrial, or non-residential customer and have questions about how these changes may affect your bill, please call us at 888-467-2669.
