One hundred years ago, electricity and natural gas service to a home or business was a luxury; today, it is essential. Yet, even though energy plays a vital role in our lives, it is easy to take for granted. We at NorthWestern Energy believe that wise use of our energy is good for the environment, saves money in your home and business and keeps our nation's energy supply more reliable.

For more than 30 years, we have worked to design and refine programs that help Montana customers use energy more wisely. We recently expanded many of the programs to our South Dakota customers.

Depending on where you live and whether we are your energy provider, we offer energy-efficiency rebates for existing and new homes and energy appraisals and audits. We also offer programs and incentives to encourage the development and use of renewable energy and low-income weatherization programs. In addition, we offer efficiency programs, rebates and incentives for commercial, industrial and irrigation customers.

For details on whether one of these programs is right for you, visit or call (800) 823-5995.
