Generac: The Leader in Gaseous-Fueled and Modular Power

From Home Standby to Industrial Might: The Generac Story

Founded in 1959 by Robert Kern, Generac built its reputation by engineering the first affordable home standby generators, effectively creating the residential backup power market. This focus on accessible, reliable power laid the groundwork for a strategic and successful expansion into the commercial and industrial sectors during the 1980s.  

A pivotal moment in the company’s history came in 1989, when Generac introduced the first-ever gaseous-fueled automatic home standby system. This early and deep investment in natural gas and propane engine technology became the cornerstone of their industrial strategy, positioning them as a leader in cleaner, cost-effective power solutions. Today, Generac is a total energy solutions company, offering one of the widest ranges of power products in the marketplace, from portable generators to multi-megawatt industrial installations.

Profile

Generac differentiates itself through a focus on innovative technology, scalability, and providing a strong return on investment.

The Generac Generator Portfolio

Generac Industrial Energy builds systems that generate, manage, and distribute power as one ecosystem.

  • Product lines: Stationary diesel, natural gas, and factory bi-fuel generators. Modular Power Systems (MPS) for paralleling. Mobile generators, ATS, BESS, and microgrid controllers.
  • Power range: About 10 kW to more than 3 MW per unit. MPS can scale to multi-megawatt solutions with built-in redundancy.
  • Fuel options: Strong emphasis on natural gas and propane, with diesel and bi-fuel for sites that want gaseous economics and diesel start reliability.

Why Generac

  • Gaseous engine expertise: Spark-ignited engines are designed specifically for generator duty. That means lower maintenance and cleaner operation for many applications.
  • Modular Power Systems: Multiple smaller units operate as one plant. Gain N+1 or N+2 redundancy, add capacity as you grow, and service units without shutting down.
  • Total energy approach: Integrate storage, controls, and on-site generation for resilience and cost control.
  • Attractive TCO: Natural gas pricing, right-sized modules, and simple scaling can make the numbers work for both CapEx and OpEx.

    Are Generac natural gas generators a good fit for cold climates?

    Many newer Cummins diesel models are HVO-capable. We verify compatibility by model and can help with fuel commissioning and documentation.

    What is a Generac Bi-Fuel generator?

    Bi-Fuel runs primarily on natural gas with diesel for ignition. It combines long runtime and lower fuel costs with the starting characteristics of diesel.

    Do used Generac generators come with a warranty?

    Used units do not carry a new manufacturer warranty, but Generator Source offers warranty options or guarantees on select units. Ask about coverage for the specific generator you are considering.

    Can Generator Source assist with installation and ongoing maintenance for a used Generac generator?

    Yes. We can handle installation and connect you with our service teams for maintenance, parts, and technical support. Service locations include Austin, TX, Brighton, CO, Jacksonville, FL, and Pensacola, FL.

    How do I know the condition of a used Generac generator?

    Every unit receives a comprehensive 31-point inspection, including load bank testing. We share reports, photos, and often videos so you have full transparency on condition and performance.

    Are replacement parts readily available for older Generac generator models?

    Yes. Generac’s global parts and service network is a major advantage. Parts for most Generac engines and generator models are widely available, which supports long-term ownership.
