200 kW standby / 175 kW prime · Natural Gas / LPG · Liquid-cooled
200 kW natural gas / LP standby generator from Blue Star Power Systems. PSI 11.1L turbocharged inline-six, Basler DGC-2020 controller, 208-600V output.
The Blue Star NG200-01 is a 200-kilowatt natural gas / LP standby generator built around the PSI 11.1-liter inline-six. It is rated 200 kWe standby / 175 kWe prime on natural gas (130 kWe standby on LP). This is one of the volume models in Blue Star's gaseous product line — appropriate for hotel, school, large multi-family, hospital non-critical, and light-industrial standby applications where natural gas is the preferred fuel.
The NG prefix in Blue Star's nomenclature designates the larger PSI HD / Doosan-PSI–powered gaseous units (above 150 kW), distinguishing them from the PS-prefix smaller-PSI-engine units and the GM-prefix small-block units.
150-200 kW continuous standby loads on natural gas or LP fuel
Sites where the gaseous fuel infrastructure is the principal advantage (no diesel storage, lower environmental risk, generally lower fuel cost per BTU)
The PSI 11.1L engine family is less common in our service territory than PSI's 8.8L V8, but the underlying service procedures are similar — spark plugs, ignition coils, charge-air cooler hoses, and oil / air filters all cross-reference to PSI's published catalog. The Basler DGC-2020 controller is consistent across the Blue Star line, so a technician familiar with one Blue Star unit can service any other in the catalog. Parts lead time from PSI's national distribution is the main consideration in markets without a local Blue Star dealer.

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 rating of the NG200-01?
The Blue Star NG200-01 is rated 200 kWe standby / 175 kWe prime on natural gas at 60 Hz / 1800 RPM per the OEM spec sheet. The LP (propane) standby rating is 130 kWe. The PSI 11.1L engine produces 315 bHp (235 kWm) at standby, leaving sufficient margin for the published 200 kWe electrical output.
What engine is in the NG200-01?
The PSI 11.1L — an 11.1-liter inline-six turbocharged-aftercooled spark-ignition engine, rated 315 bHp (235 kWm) at 1800 RPM standby. The 11.1L PSI platform is positioned between PSI's 8.8L V8 and the larger 18L and 20L engines used on competing 250+ kW-class units. It is purpose-built for stationary spark-ignition genset duty and is EPA-certified for emergency standby.
How does the NG200-01 compare to a Cummins C200 N6 or Kohler KG200?
All three are 200-kW-class natural gas standby gensets at 1800 RPM. Cummins uses its own QSJ8.9G turbocharged inline-six. Kohler uses a 14.6L V8 (KG14V) on the KG200. Blue Star uses the PSI 11.1L I-6. Cummins offers vertical integration (engine + alternator + controller all Cummins) and the densest dealer network. Blue Star's value is open-architecture componentry — engine, alternator, and controller are independent third-party brands serviceable by any qualified technician.
Can the NG200-01 run on LPG?
Yes — the NG200-01 supports natural gas, LP propane, or combined fuel operation. LP rating is typically slightly lower than NG; confirm the specific LP standby figure on the spec sheet, as it varies with fuel BTU content and inlet pressure.
