Commercial

Precision Electrical for the Spaces Businesses Depend On.

From ground-up construction to tenant improvements and full-system retrofits, Millennium Electric delivers commercial electrical work built to perform — on schedule, on spec, and up to code.

We serve office buildings, retail centers, healthcare facilities, schools, and mixed-use developments across Montana, Wyoming, and North Dakota. Our union-trained crews bring the professionalism and technical depth that commercial projects demand, with the project management to back it up.

What We Do

New Construction Full electrical scope for commercial builds from the ground up; working directly with GCs, architects, and project owners to hit milestones and deliver complete, code-compliant systems.

Tenant Improvements & Retrofits Reconfiguring an existing space or upgrading aging systems? We handle commercial TIs and retrofits with minimal disruption to your operations and tenants.
