Generac Commercial Generators, Planned Around Your Business

A commercial standby generator supplies selected building systems when utility power fails. With an automatic transfer switch, the system can detect an outage, start the generator, and transfer the connected loads to backup power.

Energo offers and installs Generac and other commercial generator systems. The right choice starts with what you need to power, the electrical capacity required, and the space and fuel options at your property. A small storefront, office building, and multifamily property can have very different requirements.

Our team helps you evaluate the equipment and installation scope that fit your building, with ongoing maintenance and repair support after installation.

Commercial Generator Installation, from Assessment to Testing

Energo helps coordinate your generator project from equipment selection and site preparation through installation and final testing. Our licensed electricians and plumbers handle the electrical and plumbing work within their trades, with project requirements reviewed for your building.

  1. Identify the essential loads. Decide which equipment and building systems need backup power, including motor-starting demands.
  2. Evaluate the site. Review generator placement, access, ventilation, exhaust, noise, and the proposed fuel supply.
  3. Plan the installation. Confirm equipment sizing, transfer-switch arrangements, required permits, and the work included in your proposal.
  4. Install and test. Complete the agreed work and check operation before the system is handed over.

For NYC projects, see the Department of Buildings guidance on emergency backup power systems. Explore our commercial plumbing and electrical services for related building work.

Plan the Right Fuel Supply for Your Generator

Your generator’s fuel must match the equipment specifications and the site’s approved installation. Commercial standby systems may use natural gas, diesel, or propane, depending on the model and applicable requirements. Fuel choice affects storage, utility connections, and refueling plans.

Energo’s commercial motor fuel services include diesel and gasoline delivery. If your equipment requires delivered fuel, tell us the specified fuel, tank details, and site access so our team can review a suitable delivery arrangement. Gasoline delivery is for compatible equipment and an appropriate on-site storage setup.

Natural gas connections and propane storage involve different planning requirements. We review fuel needs as part of the generator discussion rather than treating every system as interchangeable.

Local Generator Support for NYC-Area Businesses

Energo works with commercial properties across Brooklyn, Queens, Manhattan, the Bronx, Staten Island, Westchester, and Nassau. Our team helps building owners and property managers plan backup power around the realities of their site.

Tell us your address, building type, and whether you need a new installation or service for existing equipment. See our service areas for Energo’s wider range of building services.

Commercial Generator Maintenance & Repairs

Backup equipment needs attention even when outages are infrequent. Energo provides commercial generator maintenance and repair support to help keep your system prepared for use.

Follow the manufacturer’s service schedule, with maintenance based on the model, operating hours, and site conditions. Battery condition, oil and filters, cooling, and visible leaks all matter to readiness; an automatic exercise cycle does not replace scheduled service.

If your generator has a warning light, trouble starting, or an unsuccessful test run, share the brand, model, and symptoms with our team so we can arrange the appropriate service discussion.

Generator Pricing & Financing for Your Project

Your commercial generator installation quote depends on the equipment capacity, transfer switch, electrical and fuel connections, site access, permits, and installation work. A property assessment helps define what your project actually requires.

Energo offers financing options for qualified generator projects, subject to credit approval and applicable lender terms. Ask about current options when you request your proposal.

What Our Customers Are Saying

    I had been a Petro customer for more than 20 years, but with the cost of everything continuing to rise, including heating oil and the yearly maintenance plan, I decided it was finally time to shop around. After comparing several companies, I chose Energo. Not only did they offer the best pricing I found, but the customer service has been excellent from the very beginning. Everyone I’ve dealt with has been extremely helpful, patient, and willing to explain everything clearly. They consistently followed up after our conversations, which I really appreciated. I gave Petro the opportunity to match Energo’s pricing, but they were unable to do so. After being a customer for more than two decades, switching companies was a big decision, but Energo made the transition very easy. Immediately after I signed up, Energo arranged for a service technician to come to my home, inspect and clean the boiler, and make sure everything was in good working order. That level of attention and service gave me even more confidence that I had made the right decision. So far, I am extremely happy with my decision to switch to Energo. Great pricing, excellent communication, and outstanding customer service. I would definitely recommend them to anyone looking for a reliable heating oil and service company.

    We recently became new customers with Energo for residential heating and oil needs. From the very start It’s been a great experience. The person I’ve worked the most closely with is Effie, and she’s been amazing. The services they provide, the options offered, and the personal care they provide to make sure you are receiving the best possible experience has been very impressive. We were working with a different oil and heating company prior and the difference is extremely striking. This is so much better, so much easier, and so much more pleasant all around. I recommend them without any reservation whatsoever!

Commercial Generator FAQs

What size commercial generator does my business need?

Generator size depends on the equipment you need to power, running loads, motor-starting demands, and which systems operate at the same time. Building square footage alone is not enough. Energo reviews your backup power priorities and site conditions before recommending equipment.

How much does commercial generator installation cost in NYC?

The price depends on generator capacity, transfer-switch equipment, electrical and fuel connections, placement, site access, permits, and installation work. A site-specific proposal is the best way to compare the full project cost. Request a quote with your location and the systems you want to back up.

Do I need permits to install a commercial generator in NYC?

Yes. Permanent backup power installations in NYC require the applicable permits and properly licensed trades. The filings and approvals depend on the electrical work, fuel system, equipment location, and project scope. Energo reviews those requirements as part of installation planning.

Will a standby generator start automatically during an outage?

A standby generator paired with an automatic transfer switch can detect a utility outage, start, and supply the connected loads automatically. There is a transfer interval before generator power is available. The equipment included in the backup system determines what stays powered.

What fuel do commercial standby generators use?

Commercial standby generators may run on natural gas, diesel, or propane, depending on the model and installation requirements. These fuels are not interchangeable. The equipment specifications, available fuel supply, storage restrictions, and applicable local requirements guide the choice.

How often does a commercial generator need maintenance?

Follow the manufacturer’s maintenance schedule for the specific model and its operating hours. Site conditions and extended use can require additional service. Routine automatic exercise cycles do not replace scheduled maintenance or checks of the system’s condition.

Can Energo help with an existing commercial generator?

Yes. Energo provides commercial generator maintenance and repair support. Share the generator’s brand, model, service history, and any warning messages or starting problems so our team can review the appropriate service for your equipment.

Is financing available for commercial generator installation?

Energo offers financing options for qualified generator projects, subject to credit approval and applicable lender terms. Ask about current financing options when requesting your installation proposal.

Where does Energo offer commercial generator installation and service?
