Diesel Service & Supply

What Diesel Service & Supply does

Generator Source, LLC, operating under the brand "Generator Source," is a privately held US-based provider of commercial and industrial generator solutions, legally organized as an LLC in Colorado with headquarters at 625 Baseline Rd, Brighton, CO 80603. The company sells, services, maintains, and rents diesel, natural gas, and bi-fuel generator sets across a power range of 20 kW to 2 MW+, carrying an owned inventory of 350+ units across major OEM brands including Caterpillar, Cummins, Generac, MTU, Rehlko/Kohler, and Multiquip. It operates as a direct inventory owner rather than a broker, with a proprietary 31-point inspection process applied to all equipment before sale or rental, and EGSA-certified technicians capable of custom engineering work spanning ATS installation, control panel upgrades, frequency/voltage conversions, paralleling, load bank testing, and oil analysis across Deep Sea, Woodward, Caterpillar EMCP, and Cummins Power Command control platforms.

The company's revenue model combines one-time equipment sales (new, new surplus, and used), recurring rental revenue from rentals delivered nationwide (20 kW to 2 MW+), and recurring service revenue from preventative maintenance contracts, emergency repair, fuel delivery, and load bank testing. Service delivery is anchored by a multi-state field network covering Colorado, Florida (Jacksonville and Pensacola), and Texas (Austin), with 24/7 emergency response capability. Go-to-market is sales-led via direct phone (877-866-6895) and web-based quote requests, supplemented by a knowledge base and technical content marketing (generator calculators, fuel consumption charts, conversion tools) targeting organic search traffic.

The customer base is horizontally diversified across mission-critical facilities (data centers, hospitals, hospitality, cold storage), construction/mining/industrial, government/municipalities, and agriculture, with named testimonials spanning commercial real estate, agricultural processing, and SMB buyers. Authorized reseller partnerships with Caterpillar and other major OEMs, combined with BBB accreditation and 50+ years of combined expertise, anchor the company's brand positioning as a trusted, single-source alternative to OEM-direct or broker channels. Note: The firmographic block in the input references "Diesel Service & Supply" in Hibbing, Minnesota with 5 employees, which conflicts with the substantive operational data; the analysis above is grounded in the operational data spanning Generator Source, LLC.
