Longmont, CO

Depends entirely on what has to stay on. A small dental office keeping lights, computers, and a fridge online might be 20–30kW. A restaurant running walk-ins, the HVAC, the kitchen hood, and the POS system could be 60–100kW or more. We do a commercial load study, size to your critical loads, and give you the math in writing.

Typical range is $10,000 to $50,000 or more depending on kW size, fuel type, transfer switch complexity, concrete pad work, and enclosure requirements. We quote the whole scope — generator, ATS, fuel line, pad, permit, inspection, commissioning — as one itemized number.

Natural gas if you have commercial gas service — unlimited runtime and no refueling. Propane for facilities without gas service, with an onsite tank sized for your expected runtime. Diesel for critical facilities where fuel independence matters more than cost. We'll walk the options with you based on the site.

Yes. Commercial generator installs require building permits, electrical permits, fire department review, and utility interconnection paperwork. We file everything, handle the inspector walks, and keep the project moving so the generator is commissioned on schedule.
