The Kohler KG200 is a 200-kilowatt commercial standby generator and the largest unit in the KG industrial gaseous lineup. At this size, the architecture transitions from the 6.2L KG6208 V8 used in the KG40-KG125 to Kohler's purpose-built KG10V08T: a 10.3L turbocharged and aftercooled V8 with heavier rotating assembly, larger bearings, and longer service life expectancy.
This is the capacity range where gaseous gensets compete directly with small diesel units for institutional applications — hospitals (non-life-safety loads), government buildings, large hotels, campus distribution, and edge data centers where air quality regulations or site constraints favor gas over diesel.
Common pairing: two KG200 units paralleled for 400 kW with redundancy
The KG200 is frequently specified where the total load is 120-160 kW but the owner wants significant headroom, or where paralleling two 200 kW units provides both capacity and N+1 redundancy more cost-effectively than a single larger unit.
The KG200 large-frame platform requires more physical space for service access — the walk-in enclosure option exists for a reason. The KG10V08T is a V8 (8 spark plugs), so ignition service is comparable in plug count to the smaller KG-series V8s, but each plug change is more labor-intensive due to the engine size and packaging. We recommend the walk-in enclosure for any site where the KG200 will be serviced on a regular schedule. The turbo V8 is mechanically robust but demands attention to the charge-air cooler and turbo oil drain lines.

Estimate runtime on this tank
Fuel demand at 75% load
2,100,000 BTU/hr≈ 2100.0 cf/min @ 1,000 BTU/cf
On utility natural gas the runtime is generally unlimited provided the supply line and meter can deliver this BTU/hr at the engine's required inlet pressure (typically 5–14" WC residential, up to 5 psi commercial). Confirm against the OEM's published fuel-pressure spec.

Frequently Asked Questions
What is the standby power rating of the Kohler KG200?
The KG200 is rated 200 kW standby (180 kW prime) at 60 Hz. It uses Kohler's KG10V08T 10.3L turbocharged-aftercooled V8 — a purpose-built stationary platform shared with the KG150.
What engine is in the KG200?
The Kohler KG10V08T: a 10.3L (632 cu. in.) turbocharged and aftercooled V8 with 116.8 mm bore × 120.6 mm stroke and 9.3:1 compression. It runs at 1800 RPM (60 Hz) and is rated up to 245 kW (330 HP) on natural gas at the engine shaft.
Can the KG200 be paralleled?
Yes, with the Kohler APM603 paralleling controller and appropriate switchgear. Paralleling two KG200 units provides 400 kW with N+1 redundancy capability.
What ATS for 200 kW?
At 480V three-phase: 300-400A ATS. ASCO 7000 Series or Kohler KCS are standard at this capacity. For critical facilities, consider bypass-isolation configuration.
