In an era of increased attention to energy issues and related costs, more and more people are looking for ways to manage energy consumption. That is why NorthWestern Energy created the Efficiency Plus (E+) brand to signal ways that the consumer can reduce their use and seize the savings.

Because we are a regulated utility, E+ program offerings vary depending upon which state you live in. Nevertheless, no matter where you are - NorthWestern Energy has many helpful ways to be energy efficient.

We created the Efficiency Plus (E+) brand to identify tools and information for our customers to better manage their overall energy costs and, where applicable, obtain rebates or incentives to help offset the purchase and installation of qualifying measures.
