NorthWestern Energy offers multiple rebate programs for commercial and industrial customers to make energy efficient improvements to their businesses. This includes lighting, heating, irrigators, insulation, VFDs, refrigeration, air conditioning, appliances, and water heating incentives. Equipment requirements and specific rebate amounts can be found on the program web site.

The E+ Commercial Lighting Rebate Program offers rebates for the removal of old, less efficient lighting products which are replaced with high efficiency technologies. The program is primarily for retrofit projects. Specialized lighting application projects in new construction will be considered on a case-by-case basis. Program specifications can be found in the rebate application form.

The E+ Premium Efficiency Motor Rebate Program offers commercial and industrial customers incentives for motor retrofits or new construction. Motor purchases placed in stock are not eligible for this rebate. A chart of the rebate amounts can be found on the motor rebate application form. The application must be received by NorthWestern Energy within 90 days of motor purchase. NorthWestern Energy also provides a Motor Rewind Rebate Program to help customers reduce electricity costs when rewinding existing electric motors. Motors between 20 horsepower (HP) and 500 HP with a standard motor design (such as NEMA Premium and Epact), rewound by qualified Green Motors Practice Group members, will qualify for this rebate.
