Commercial backup is about protecting what your business cannot afford to lose: refrigeration, point-of-sale, servers, medical or dental equipment, security, and the lights and HVAC that keep customers and staff comfortable. We size the generator to your critical loads, favor an automatic transfer switch for hands-free changeover, and plan the installation to minimize disruption to your operation. The result is a business that keeps working through the outages that shut competitors down.
Whether you run a restaurant, a medical or dental office, a retail store, or a facility with critical equipment, one call gets you a licensed electrician and Generac dealer who sizes commercial backup correctly and installs it right.

02 — THREE REASONS
Three Reasons Businesses Invest in a Standby Generator
An outage costs more than the generator
For most businesses, a single extended outage means lost sales, spoiled product, missed appointments, and idle staff, and a bad storm can do it repeatedly. A commercial generator turns those losses into a non-event, keeping the doors open while competitors go dark. A restaurant that loses a walk-in cooler, or a dental office that cancels a day of appointments, can see the cost of one bad storm rival the cost of the generator itself.
Critical loads cannot wait for the grid
Refrigeration, servers, medical and dental equipment, security systems, and life-safety systems do not tolerate an outage, and some carry regulatory or liability exposure if they go down. A standby generator with an automatic transfer switch keeps these critical loads running within seconds of a power outage, with no one on-site needing to act. For medical, dental, and food-service operations, that is about compliance and safety as much as revenue.
Authorized-dealer installation and support
A commercial generator is a serious investment, and as a Generac Authorized Dealer, we install it to factory standards, register the warranty, and back it with our workmanship warranty. That matters most during the high-demand windows after a regional storm, when the difference between a dealer relationship and a general installer is how quickly your business is back up.

05 — HOW WE SCOPE COMMERCIAL GENERATORS
How We Scope a Commercial Generator
Commercial generator pricing depends entirely on the system's size and complexity, so we scope and quote each project individually after assessing your business.
What drives a commercial generator project
The generator size your critical loads require, single-phase versus three-phase power, the transfer switch and load management, the fuel source and distance, any service or panel work, and your facility's layout all shape the project. A small office and a full-service restaurant or medical facility are very different jobs, and we scope to yours.
A firm, itemized proposal
Rather than a generic price, we provide a written, itemized proposal after a site assessment, so you see exactly what the system includes and what it costs. We size to what your business actually needs, so you are not paying for capacity you will not use or leaving critical equipment unprotected.
06 — VIRGINIA BEACH LOCAL CONDITIONS
Virginia Beach Conditions That Affect Commercial Backup
Commercial backup power has specific local drivers in this region. Here is what matters here.
Storms shut local businesses down
This region loses power in hurricanes, nor'easters, and summer storms, sometimes for days, and every one of those outages is lost business for operations without backup. That recurring exposure is exactly why commercial standby generators are a sound investment here, and we size them for the multi-day outages our storms actually produce, not a brief flicker. A business that plans backup around a two-hour interruption is unprepared for the reality of a regional storm that keeps the grid down for three or four days, which is the scenario we design around here.
Critical facilities cannot go dark
This area has a dense mix of medical and dental offices, restaurants, retail, and small industrial operations, many with refrigeration, servers, or patient-care equipment that cannot lose power. For these businesses, an outage is more than an inconvenience, and we build backup around the specific critical loads each operation depends on. A server room, a walk-in cooler, and a bank of exam-room equipment each have very different power needs, and we scope the generator to the loads that actually keep your particular business running.
Dealer support matters most after a storm
When a named storm hits, demand for generators, parts, and service spikes across the region at once, and that is when a Generac dealer relationship counts. Our dealer relationship means parts and factory support during those high-demand windows, which is precisely when a business most needs its backup power backed by more than a one-person shop.
Natural gas in the city, three-phase where needed
Many commercial sites in the built-up parts of Virginia Beach, Chesapeake, and Norfolk have natural gas, which we favor for a commercial generator, so there is no tank to manage, and many carry three-phase power that the generator and transfer switch must match. We handle both, matching the system to your building's actual fuel and power rather than a residential default.
Salt-air siting for the enclosure
A commercial generator sits outside for its whole life, and coastal salt air corrodes outdoor equipment, so placement and the connections around it matter more here. We site the unit and its transfer equipment thoughtfully and use corrosion-aware practices, so the generator holds up in a coastal environment.
