Bozeman Solar Project

The City of Bozeman partnered with NorthWestern Energy to install a 385 kW utility scale solar array at the Wastewater Treatment Facility. The City of Bozeman is leasing the land to NorthWestern Energy for 5 years, and NorthWestern Energy was responsible for all costs associated with the project. Montana State University is an additional project partner. The project covers 2.5 acres and incorporates 1,152 solar panels, and will produce enough electricity to offset the annual consumption of 60 Montana homes. 

 A key component of the electrical design was NorthWestern Energy's desire to test "smart inverter" functions in relationship to large scale integration of distributed energy systems on their utility grid. A communication tower at the site allows NorthWestern Energy to remotely control the advanced inverter functions while also providing a platform for system monitoring and data acquisition. A publicly accessible website will be available with details system information and real time power production.


 The City of Bozeman is working with the Montana Renewable Energy Association to review local processes to identify opportunities for improved efficiencies to make installation of solar energy systems more accessible to Bozeman residents and businesses. Learn more here.

Energy Retrofits

The City of Bozeman is continually looking for opportunities to increase the energy efficiency of our own facilities and operations. We are currently implementing an LED street light retrofit, and  completed an investment grade energy audit through McKinstry in 2016 and are in the process of implementing recommended efficiency projects from that audit. 

Idle Free Bozeman

It’s as simple as turning your key when you’ll be stopped for 30 seconds or longer. Save gas, save money, no-brainer.

Idle Free Bozeman is focused on reducing vehicle idling in Bozeman. Idling contributes to poor air and water quality, and generates unnecessary greenhouse gas emissions. Idle Free Bozeman has done baseline monitoring on current habits, given a survey on motivations for idling, created educational materials, and is planning many outreach strategies in the community at large.



Energy Retrofits

The City of Bozeman is continually implementing energy retrofits on City-owned facilities, including an LED Streetlight project and an investment grade audit through McKinstry.
