Billings is Montana's largest city and sits in the Yellowstone River valley at approximately 3,100 feet elevation. NorthWestern Energy is a true single utility — it serves both electricity AND natural gas for most of Billings, which simplifies coordination for heat pump conversions and any project touching both systems.
NorthWestern Energy serves Billings for both electricity and natural gas (1-888-467-2669 / northwesternenergy.com). For kitchen projects involving both gas appliances and electrical circuits, one call to NorthWestern covers all utility coordination. Confirm gas availability and stub-in at your address before finalising any gas cooking design.
Most Billings single-family homes have full basements — the Yellowstone River valley's residential construction overwhelmingly uses basement foundations. Kitchen drain and supply lines run in the basement ceiling and are accessible from below without any floor cutting. This is a significant cost advantage over slab-on-grade markets: moving the kitchen sink or adding an island drain can typically be done from the basement without opening the kitchen floor.
