NorthWestern Energy offers multiple rebate programs for commercial and industrial customers to make energy efficient improvements to their businesses.  The E+ Commercial Natural Gas Savings Program, for both existing businesses and new construction, offers incentives on a variety of equipment designed to improve energy efficiency. Many of the rebates are calculated based on KBtu/hr output rating of installed equipment. Prior to rebate payment, NorthWestern Energy representatives may inspect completed jobs.
