Commercial Generators & Backup Power in Manchester, NH

New Hampshire's grid takes a beating — nor'easters, ice storms, and summer microbursts knock out Eversource service somewhere in the region every year, and the outages rarely respect business hours. For a restaurant, that's a walk-in full of spoiled inventory. For a medical office, it's a canceled schedule and refrigerated vaccines at risk. For a warehouse near the airport moving freight on deadlines, it's a dock at a standstill. A properly installed standby generator turns all of that into a thirty-second blip.

Generator projects succeed or fail at the sizing stage, so we start with your load reality: which circuits must stay live, which can wait, and what the true startup demand looks like when compressors and motors all try to come back at once. From there we handle the complete installation — pad and placement, fuel coordination with your propane or gas supplier, automatic transfer switch wiring, and load-shed provisions when it makes sense to back up the essentials instead of the whole building.

Standby power is life-safety-adjacent work with real code requirements, and we treat it that way: NH electrical permits, state inspection, and commissioning under load before we call it done. We also service and maintain existing commercial generators, because the machine that saves your quarter is the one somebody exercised, load-tested, and inspected all year.
