Kohler KG100

Overview#

The Kohler KG100 is a 100-kilowatt commercial standby generator and the first turbocharged unit in the KG gaseous lineup. Below it, the KG60 and KG80 use naturally-aspirated engines; at 100 kW and above, Kohler transitions to forced-induction platforms that deliver more power from a similar footprint.

This is the sweet spot for medium-to-large commercial facilities: full-service hotels, large retail centers, multi-family residential buildings, light industrial operations, and non-critical hospital loads where gaseous fuel is preferred over diesel.

The turbo difference#

The KG100's turbocharged inline-6 is a meaningful platform change from the KG60/KG80 naturally-aspirated V8s:

• Higher power density — 100 kW from a package similar in size to the 80 kW NA unit
• Better fuel efficiency under load (turbo recovers exhaust energy)
• Smoother operation — the inline-6 is inherently balanced vs the V8's secondary vibration
• Additional service item — turbo bearings and intercooler hoses are new wear items not present on the NA units

Sizing guidance#

• 80 kW continuous at 80% loading
• Motor starting up to 15 HP without soft-start
• Step up to KG125 if peak demand exceeds 80 kW or large motor starts are frequent

The KG100 is the right call when your load study shows 60-80 kW peak with meaningful motor-starting transients that the KG80 can't absorb cleanly.

OnPoint service experience#

The KG100 turbo platform requires slightly different attention than the NA units below it. We add turbo inspection (bearing play, oil drain condition, intercooler hose integrity) to the annual service checklist. Otherwise, the ignition and coolant service patterns mirror the rest of the KG line. The inline-6 is notably smoother and quieter than the V8 under sustained load — building occupants notice the difference.
