Kohler Power Systems has manufactured industrial generators since 1920 — longer than any other major generator brand. Power Generation Enterprises maintains California's largest inventory of Kohler commercial and industrial generators, with units from 100kW to 1,500kW available from our Santa Clarita facility. Our Kohler inventory spans diesel, natural gas, and bi-fuel configurations, covering EPA Tier 2 through Tier 4 Final emissions standards.
The Kohler REZGT series leads California's natural gas generator market, offering CARB-compliant operation with the reliability demanded by hospitals, data centers, and high-rise commercial buildings. On the diesel side, the Kohler REOZJD and REOZMD platforms deliver proven performance in construction, healthcare, and municipal applications. Kohler's signature Fast-Response excitation system stabilizes voltage within 10% within one cycle — critical for sensitive electronic loads.
Kohler-specific advantages: Kohler builds its own engines, alternators, and transfer switches — vertical integration that gives you a single-source warranty and eliminates the finger-pointing between component suppliers common with other brands. Kohler automatic transfer switches (ATS) are among the most specified in commercial construction. We stock both generator sets and Kohler ATS units.

Kohler Power Systems has manufactured generators since 1920 — making Kohler the oldest continuously operating generator manufacturer in the United States. Founded by Walter Kohler Sr. to power his Wisconsin manufacturing plant, the power systems division has grown into a global leader in commercial and industrial generator production from 10kW to 4MW. Kohler's vertical integration — manufacturing its own engines, alternators, and automatic transfer switches — gives buyers a single-source warranty and eliminates finger-pointing between component suppliers that plagues other brands. The Kohler REZGT series dominates California's natural gas generator market; the REOZJD and REOZMD diesel series are specified by hospitals, data centers, and commercial developers across the country.
Kohler manufactures the engine, alternator, transfer switch, and controls — providing a single-source warranty, one contact for service escalation, and seamless ATS integration.
Kohler's Fast-Response excitation stabilizes output voltage within one electrical cycle of applying full load — critical for motor loads, elevators, and sensitive equipment.
Kohler manufactures a full range of automatic transfer switches from 100A to 4,000A+ — allowing complete system sourcing from one manufacturer with a unified warranty.
Kohler PowerBoost delivers extra starting current during the first moments of load application, allowing the generator to start larger motors and compressors without oversizing.
Kohler REOZJF and REOZMD diesel series are available in Tier 4 Final configurations, meeting EPA and CARB standards. Kohler was among the first OEMs with factory-integrated Tier 4 Final systems.
Kohler's REOZGT natural gas generator series (100kW-600kW+) is CARB-compliant — the preferred choice for California commercial standby applications where diesel permitting is restricted.

How Much Does an Industrial Generator Cost? Complete Pricing Guide 2026Top 10 Kohler Diesel Generators for Sale in 2025Kohler industrial generator prices range from $25,000-$55,000 for the 125REZGT natural gas model to $225,000-$350,000 for the 1500REOZDD diesel system. The 275REOZJF (275kW diesel) runs $55,000-$95,000; the 500REOZMD (500kW) runs $85,000-$145,000. California's largest Kohler inventory is at Power Generation Enterprises — call (818) 484-8550 for current pricing.
The Kohler REZGT series is Kohler's natural gas generator line from 100kW to 600kW+. The 125REZGT (125kW) is the most widely specified model in California commercial standby applications. REZGT generators are CARB-compliant, feature Kohler's Fast-Response excitation system, and are powered by Kohler's own engines — providing a single-manufacturer warranty covering engine, alternator, and controls.
Kohler's key differentiator is vertical integration — they manufacture their own engines, alternators, and transfer switches, providing a single-source warranty and single point of accountability. CAT and Cummins have larger dealer networks. For buyers in the 100-1,500kW range who value warranty simplicity and ATS integration, Kohler is an excellent choice.
Kohler's Fast-Response excitation system stabilizes generator output voltage within 10% of nominal within one electrical cycle of applying full load — significantly faster than many competing generators. This is critical for facilities with large motor loads (HVAC, elevators) or sensitive electronic equipment that cannot tolerate voltage sags during generator startup.
Yes. Kohler REOZJF and REOZMD diesel series are available in Tier 4 Final configurations meeting EPA and CARB requirements. Kohler was among the first generator manufacturers to offer factory-integrated Tier 4 Final systems across its commercial product line. Contact Power Generation Enterprises for current Tier 4 Kohler inventory.
Yes. Kohler manufactures a complete line of automatic transfer switches from residential 100A units to industrial 4,000A+ switchgear. Kohler ATS units are specified by electrical engineers on commercial and healthcare projects nationwide. Power Generation Enterprises stocks Kohler ATS units alongside generator sets for complete system sourcing.
Kohler dominates the commercial and industrial generator market (100kW+); Generac is stronger in the residential and light commercial segment (up to 150kW). Kohler's industrial product line is rated for heavier duty cycles and has a more robust dealer/service network in commercial construction. For commercial and industrial applications, Kohler is generally the preferred specification.
Kohler PowerBoost delivers extra current during the first moments of load application — useful for facilities with large motor loads. It allows the generator to start motors and compressors that would otherwise require an oversized generator. PowerBoost is standard on Kohler commercial generator sets.
Kohler industrial generators are designed for 30,000+ hour service lives in standby applications. Kohler's factory maintenance schedule calls for oil and filter changes every 500 hours, annual load bank testing, and major inspections at 6,000-hour intervals. Single-manufacturer (engine, alternator, controls) maintenance simplifies the service relationship.
Yes to both. Power Generation Enterprises ships Kohler generators from our Santa Clarita, California facility — California's largest Kohler inventory. Financing is available for qualified buyers. Call (818) 484-8550 for current availability, pricing, and financing options.
