Commercial standby generator installation for restaurants, medical offices, retail centers, and multifamily properties throughout Miami-Dade and Broward County. Automatic transfer — no manual intervention required.
From a 30 kW unit for a small restaurant to a 500 kW installation for a multifamily complex, we handle every phase of the project — design, permitting, installation, and commissioning.
Full commercial installation including concrete pad, transfer switch wiring, fuel system connection, and utility coordination. We handle everything from design through final inspection and commissioning.
An ATS is what makes a standby generator actually standby. It monitors grid power 24/7 and switches to generator automatically within seconds — no employee needs to do anything for your operation to stay running.
Proper sizing starts with knowing what you actually need to power. We assess your critical circuits — refrigeration, HVAC, lighting, equipment — and calculate the minimum and recommended generator size before quoting anything.
Most commercial generators in South Florida run on natural gas (connected to the utility line) or propane. We install the fuel system for either option and coordinate with the utility for natural gas tie-ins.
Some buildings need a panel upgrade or a subpanel to properly integrate a commercial generator. We assess your existing service and make any necessary upgrades so the generator powers the right circuits reliably.
A generator that hasn't been run in months may not start when you need it most. We offer maintenance contracts for commercial generators — oil changes, load bank testing, battery checks, and transfer switch verification.
When a major storm moves through South Florida, some neighborhoods lose power for three days. Some for two weeks. The businesses still operating during that window — the restaurants feeding first responders, the pharmacies filling prescriptions, the hotels housing displaced families — are the ones that installed generators before the season started.
A commercial standby generator isn't an optional amenity. For most South Florida businesses, it's insurance against the kind of loss that doesn't appear on an insurance claim.
Walk-in coolers, fryers, refrigeration, and POS — a full kitchen demands 45–100 kW. Food safety regulations don't allow exceptions for weather events.
Exam equipment, refrigerated medications, and patient safety systems require reliable backup power. NFPA 99 sets specific requirements for healthcare facilities.
Elevators, water booster pumps, common area lighting, access control, and security cameras — all critical systems that tenants depend on around the clock.
Staying open while competitors are dark is one of the strongest competitive advantages a South Florida business can have during and after a major storm.
Every site is different, and we always perform a load analysis before recommending a size. The table below reflects common scenarios for South Florida commercial properties.
| Business Type | Typical Size | What It Covers | Avg. Installed Cost |
|---|---|---|---|
| Small Office / Retail Suite | 20–45 kW | Lighting, outlets, 1 HVAC unit, POS | $8,000–$18,000 |
| Restaurant (Full Kitchen) | 45–100 kW | Kitchen equipment, walk-in refrigeration, HVAC, POS | $15,000–$35,000 |
| Medical Office / Clinic | 80–150 kW | Exam equipment, refrigeration, full lighting, HVAC | $20,000–$50,000 |
| Large Commercial Building | 150–250 kW | Full building — all circuits and systems | $35,000–$80,000 |
| Multifamily / Apartment Complex | 150–500 kW+ | Elevators, pumps, common areas, select units | $50,000–$150,000+ |
Costs are installed estimates including generator unit, pad, transfer switch, fuel system, and permit fees. Actual cost depends on site conditions, generator brand, and fuel type selected.

Every year, South Florida businesses wait until they see storm coverage on the news to start calling generator companies. By then, unit lead times have stretched to 6–8 weeks, crews are booked out, and permit offices are backed up.
Businesses that install before May consistently get better availability, shorter lead times, and more thorough installations because their crews aren't racing a deadline. Here's what off-season installation looks like compared to storm season:
Questions we hear from property managers, business owners, and GCs before their first commercial generator project.
Commercial installations involve larger units (20–500 kW vs. 11–24 kW residential), three-phase power in many cases, more complex automatic transfer switch configurations, and stricter permitting requirements in Miami-Dade and Broward. Commercial sites also often require a concrete equipment pad, extended fuel runs, and coordination with the utility for natural gas tie-ins. We handle all of it — the process for the client is the same as residential, just with more moving parts on our end.
Sizing depends entirely on your critical loads. A small office or retail space typically needs 20–45 kW. A restaurant with full kitchen and walk-in refrigeration usually requires 45–100 kW. Medical offices and clinics commonly need 80–150 kW. Multifamily properties range from 150 kW to 500 kW or more, depending on how many systems need to stay on. We perform a load analysis before recommending any generator — oversizing wastes money, undersizing means something you needed still goes dark.
Yes — automatic transfer switches (ATS) are standard on every commercial generator installation we do. An ATS monitors the utility feed constantly and switches to generator power within 10 seconds of detecting an outage. No employee has to flip a switch, turn a key, or even be on site. We install both open-transition and closed-transition transfer switches depending on whether the business can tolerate the brief interruption during switchover.
Once the generator is on-site, most commercial installations take 2–5 days from delivery to energization, depending on generator size, site conditions, and fuel system complexity. The bigger variable is the permit timeline: Miami-Dade typically processes commercial electrical permits in 1–2 weeks during non-storm season. During the 4–6 weeks before hurricane season, both unit delivery and permit processing slow significantly. We're transparent about timelines in every estimate so you can plan around them.

Availability fills up in April and May. The businesses that aren't scrambling in June are the ones that planned ahead.
