NorthWestern Energy - Custom Business Efficiency Program

July 21, 2023


The E+ Business Partners Program offers funding for electric and/or natural gas energy efficiency and/or load management projects in retrofit and new construction applications including commercial, institutional, industrial, agricultural, and multi-family residential facilities/systems. Both natural gas and electric customers are eligible for this program. It is not available for businesses already enrolled in the electric or natural gas “Choice” programs.

NorthWestern Energy will examine the level of funding or advisory services it will invest in specific conservation or load management measures based on the life expectancy, reliability, and availability of the conservation resource, cost to NorthWestern Energy of administering the project, level of design assistance funding already attained, the projected payback to the entity owner, funding available from other sources, the value to the distribution system, and the renewable resource available.

Projects must demonstrate the cost-effectiveness of specific conservation and/or load management measures. These projects must also assure reliability and availability of equipment, while demonstrating the availability of qualified design services, contractors, and maintenance services. The deadline for project RFP submissions is June 30 annually. Customers should call the Regulatory Support Services department at 1-888-700-6878 for more information.
