E+ Green for Montana Customers

NorthWestern Energy’s electricity supply mix for our Montana customers includes nearly 60% clean energy made.

Our Montana electric customers can "green up" their electricity usage with green power. You don’t have to install anything or make a big investment. The E+ Green Program gives you a way to reduce your electricity-based carbon footprint and supports the development of new renewable generation. Use the E+ Green Calculator to see the expected addition to your monthly bill.


To learn more or sign up, call 888-467-2669 or contact us via the link below.

For example, an average NorthWestern Energy residential electric customer in Montana uses about 750 kWh a month.
  • If an average customer wants to add 40% more carbon-free electricity, they would buy 3 blocks of E+ Green for an extra $3.75 a month.
  • If an average customer wants to add 100% renewable resources, they would buy 8 blocks for an additional $10 a month.

Your E+ Green charges will be added to your NorthWestern Energy bill and you may change the amount you buy at any time.

For more information or to sign up, call 888-467-2669 or contact us.


Note: The E+ Green Program is offered to Montana electric customers as a regulated program as required by Montana law.

NorthWestern Energy supports the E+ Green program with renewable energy certificates (REC) purchased from the Bonneville Environmental Foundation from resources in the Northwest, Montana as available, or Wyoming.
