Blue Star PS150-01
150 kW standby · Natural Gas / LPG · Liquid-cooled
150 kW natural gas / LP standby generator from Blue Star Power Systems. PSI 8.8LTCAC turbocharged-aftercooled V8, DSE DCP7310 controller, single- and three-phase 120-600V.
The Blue Star PS150-01 is a 150-kilowatt natural gas / LP standby generator built on the PSI (Power Solutions International) 8.8LTCAC turbocharged-aftercooled V8. It is rated 150 kWe standby on natural gas and 125 kWe on LP at 60 Hz / 1800 RPM. Available in single-phase (120/240V) and three-phase (120/208V, 240V, 480V, 600V) configurations. Controller is the DSE DCP7310. Fuel pressure requirement is 11 in. water column — standard utility service.
The PS prefix in Blue Star's model nomenclature denotes the PSI engine family. Larger Blue Star gaseous units use the NG prefix.
The PSI 8.8LTCAC platform is one we service across multiple brands at the 150 kW class, so the PS150-01 is functionally familiar despite the Blue Star packaging. Standard service items — spark plugs, air filter, oil and filter, ignition coils — cross-reference to PSI's published catalog. The DSE DCP7310 controller is the same unit found across Blue Star's current gaseous lineup, making programming and diagnostics consistent with their larger models.

Adjust load percent and tank size to estimate runtime. Pre-filled with this model's spec where available.
Estimate runtime on this tank
Fuel demand at 75% load
1,575,000 BTU/hr≈ 1575.0 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 PS150-01?
The Blue Star PS150-01 is rated 150 kWe standby on natural gas and 125 kWe standby on LP at 60 Hz / 1800 RPM. It is available in single-phase (120/240V) and three-phase (120/208V, 240V, 480V, 600V) configurations. Fuel pressure requirement is 11 in. water column.
What engine is in the PS150-01?
The PSI 8.8LTCAC — Power Solutions International's 8.8-liter turbocharged-aftercooled V8 spark-ignition engine rated for stationary standby duty. This platform is EPA certified under 40 CFR 60 Subpart JJJJ and shares the same basic architecture found in several competing 150 kW gaseous standby units.
Is single-phase output available on the PS150-01?
Yes. The PS150-01 is one of the few Blue Star gaseous models available in single-phase — 120/240V single-phase via the Stamford UCDI274J1 alternator. Three-phase configurations are 120/208V, 240V, 277/480V, and 347/600V. This single-phase option is not available on larger Blue Star gaseous models (NG300-01 and above are three-phase only).
How does the PS150-01 relate to the NG150-01?
Both are 150 kWe standby NG/LP generators on the PSI 8.8LTCAC V8, sharing nearly identical specifications. The PS prefix and NG prefix models in this size class use the same engine platform — confirm with Blue Star which chassis and controller variant applies to your specific order. The NG150-01 appears in Blue Star's current NG-designated gaseous catalog.
What is the fuel pressure requirement for the PS150-01?
The PS150-01 requires 11 in. water column inlet fuel pressure — standard utility residential and light-commercial NG service. This is substantially lower than the 30 in. WC required by larger Blue Star gaseous units (NG800-01 and above). Verify sustained pressure under full load at the regulator outlet before commissioning.
