"Trail Mountain ran our data center expansion like a Tier III is supposed to run — clean drawings, paralleled the gear without a single false transfer, and finished seven weeks ahead of schedule. They were the only contractor on site whose punch list we accepted on first walk."

Overview
Whole-home, commercial, and NFPA 110 life-safety generator systems. We're a Generac Premier Dealer, a Kohler authorized installer, and we self-perform gas, electrical, ATS, and concrete pad — one contractor for the full scope.
Standby power is only as good as the install. We've seen too many improperly grounded generators, oversized starts that trip the utility, and ATS units installed without arc-flash labeling. Our generator practice fixes that — every install includes a coordinated load study, properly sized ATS, gas-line sizing per NFPA 54, and a commissioning test that proves the unit actually starts under load.
We're a Generac Premier Dealer (top 5% nationally), a Kohler authorized installer, and we hold service certs for Cummins and Briggs. For commercial and healthcare clients we deliver NFPA 110 Type 10 emergency power supplies with annual load-bank testing and a maintenance bench staffed by factory-trained techs.
Service contracts include scheduled oil changes, coolant and filter replacement, exercise verification, transfer-switch testing, and a 24/7 dispatch line. We track every unit's runtime in our CMMS so owners get warning before parts wear, not after.
Capabilities
What we self-perform under this discipline.
Our crews self-perform every capability listed below. We sub specialty trades only when the scope demands it, and we manage them under our prime contract.
- Whole-home generators (Generac, Kohler, Cummins)
- Commercial standby (50kW–2MW)
- NFPA 110 healthcare and life-safety EPSs
- Automatic transfer switch (ATS) install and integration
- Concrete pad, gas, and electrical (one contractor)
- Annual load-bank testing and PM contracts
- Fuel system design (LP, natural gas, diesel)
- Generator-paralleling switchgear
Frequently asked
Common questions about this service.
- Most Wasatch-area homes between 2,500 and 6,000 sq ft are well-served by a 22–26kW air-cooled unit. Larger estates, homes with multiple AC condensers, or homes with electric ranges and heat may need a 36–48kW liquid-cooled unit. We do a load survey before quoting.
- Yes. Almost every Utah AHJ requires an electrical permit, a mechanical permit (for gas), and sometimes a separate structural review for the pad. We pull every permit as part of a turnkey install — homeowners don't deal with the city.
- Air-cooled residential: oil change at 100–200 hours or annually, whichever first. Liquid-cooled commercial: per manufacturer, typically 250 hours or annually. NFPA 110 life-safety: monthly exercise plus annual load-bank test. We have PM contracts for all three tiers.
What clients say
Owners and general contractors keep coming back.
Roughly 70% of our annual commercial volume is repeat business with the same owners and GCs. Below are recent quotes, all attributed and verifiable.
"We've used Trail Mountain on three hospital pavilions now. They self-perform the work, they understand NFPA 99, and they bring documentation that makes our QA team's job easier — not harder. They're our go-to electrical contractor for healthcare in Utah."
"Our 20,400 sq ft Promontory home had a Lutron HomeWorks panel with 340 channels, hybrid Powerwall and Kohler standby, snowmelt, architectural lighting — Trail Mountain commissioned the whole house in a single pass with zero punch items. That doesn't happen."
"We selected Trail Mountain for the I-15 NEVI corridor because they could actually deliver eleven sites in nine months. Every site passed FHWA reimbursement on the first audit, and uptime has held above 99% since commissioning."
"Our cleanroom expansion happened inside a fully operational biotech facility. Trail Mountain coordinated through QA, met our IQ/OQ timeline with zero rework, and our validation team accepted their documentation on first review — which never happens with electrical."
"I've worked with maybe a dozen solar contractors across Utah. Trail Mountain is the only one I'd hand a 12MW ground-mount and an 8MWh BESS to without sleepless nights. They commissioned three months early. We saved $1.8M in MACRS and ITC."
