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 service-entrance work, panel upgrades, or any project touching both systems, one call to NorthWestern covers all utility coordination. Start contact the same day as city permit submission — service scheduling adds 2–5 weeks.
Billings' older housing stock in the Heights, West End, and downtown-adjacent neighbourhoods may have 100A service from mid-century upgrades. EV chargers (7–11 kW) and cold-climate heat pump circuits added to a 100A panel push capacity limits. A MT licensed electrician should assess panel capacity before adding high-draw circuits. NorthWestern's single-utility structure means the panel upgrade and any related gas service coordination can both be handled through one contact.
