NorthWestern Energy offers a variety of rebates for residential customers to make energy efficiency improvements in their existing homes. Customers who purchase or implement energy efficient appliances, lighting, HVAC services, insulation and programmable thermostats are eligible for prescriptive rebates from NorthWestern. There are also many rebates available for both electric and natural gas space and water-heating. Details for all rebate offerings are found on the program web site listed above.

In addition to the home improvement rebates listed above, The E+ New Homes Program offers rebates for new home construction that incorporates certain energy efficiency measures. Members can receive rebates in the new home program in three ways: By installing Energy Star® light fixtures and CFLs, by building a home that qualifies under the NorthWestern Energy Star Homes standards, or by including other specific energy efficiency measures in the new construction.
