E+ Energy Efficiency Offerings

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.

Top 10 Tips for Energy Efficiency

  1. Compare your energy usage on your billing statement from month to month and from year to year to become aware of what impacts your energy use.
  2. Evaluate your insulation levels to determine if you have enough to keep you warm in the winter and cool in the summer. In the winter, cold floors and walls are a sign of a poorly insulated home.
  3. Check your hot water heater’s temperature to make sure it’s safe and efficient — 120 degrees is plenty!
  4. Check your refrigerator and freezer temperatures to make sure the refrigerator is set between 37 and 40 degrees F and your freezer temperature is between 0 and 5 degrees F.
  5. Check your heating equipment to make sure it is working properly and clean or replace the furnace filters.
  6. Inspect your windows and doors for air leaks. If you see daylight around a door or window frame, then the door or window leaks. Seal up the leaks by caulking, adding weather stripping, or installing a door sweep.
  7. Wrap your hot water tank and install pipe insulation on the first 10 feet of the hot water pipe.
  8. Install low-flow faucet aerators and showerheads.
  9. Replace incandescent light bulbs that are used more than three hours a day with energy-efficient CFLs or LEDs.
  10. See what rebates or tax credits may be available for qualifying insulation measures, programmable thermostats, and high efficiency natural gas equipment.

Is your home energy efficient?

The greenest kilowatt hour is the one that is never generated. That’s why energy efficiency is an important first step in a “greener” energy footprint. We offer the FREE E+ Home EnergyCheck to our Montana space or water-heating customers. It’s a great way to learn and find ways to reduce your current energy consumption and make your home energy efficient.

If your home doesn’t qualify for our EnergyCheck program, we recommend you check out the ENERGY STAR Home Advisor® to see what might make sense for your home. After you’ve taken steps to reduce your energy usage through improvements such as additional insulation, air sealant measures, lighting, windows, ENERGY STAR appliances and electronics, etc., then adding a renewable energy system may be your next choice.
