Overview#
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-powered gaseous units above 130 kW, distinguishing them from the PS-prefix units (PSI 8.8L V8) and the GM-prefix small-block units.
The PSI 11.1L inline-six#
PSI's 11.1L spark-ignition platform sits in the middle of the company's industrial-genset engine lineup:
- Inline-six rather than V8 — slightly longer engine but simpler service access on critical-path components
- Turbocharged with aftercooling for the power density needed at 200 kW
- Purpose-built for natural gas / LP — not a converted diesel or automotive engine
- EPA Stationary Spark Ignition certified for emergency-standby duty under 40 CFR 60 Subpart JJJJ
When to spec the NG200-01#
- 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)
- Facilities preferring open-architecture componentry — PSI engine, third-party alternator, DSE DCP7310 controller — over proprietary OEM platforms (Cummins PowerCommand, Kohler KG)
Our service experience#
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 DSE DCP7310 controller is consistent across Blue Star's current gaseous 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.
