Maps & Data

See the latest trends and get the information you need about distributed generation (net metering), community scale, and utility scale renewable energy generation in Montana.


This series of maps and charts illustrates current and historical development of renewable energy in Montana, including both on-site 'net metering' systems and utility scale projects.

The Net Metering, All Utilities page summarizes data about on-site solar photovoltaic, wind and hydroelectric systems interconnected to one of 15 Montana electric utilities. Additional data is provided specifically for NorthWestern Energy net metering systems. Off-grid projects and solar thermal systems are not included at this time.

Utility scale projects are mapped separately. Those projects include renewable energy generating facilities (wind, hydroelectric, biomass, landfill/wastewater methane) in Montana that sell electricity to a utility, or that are owned by a utility.

Data was last updated December 2017.
