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 8.8L turbocharged V8 with charge-air cooling, Basler DGC-2020 controller, 208-600V output.
The Blue Star PS150-01 is a 150-kilowatt natural gas / LP standby generator built around the PSI (Power Solutions International) 8.8L turbocharged-aftercooled V8. It sits in Blue Star's middle gaseous range — appropriate for medium-commercial standby loads where a gaseous fuel supply is preferred over diesel: medium retail centers, full-service hotels, schools, multi-family residential, and light-industrial.
The PS prefix in Blue Star's model nomenclature denotes the PSI engine family; the GM prefix denotes their smaller GM-derived gaseous platforms, and the NG prefix denotes their larger PSI HD / Doosan-PSI gaseous range.
PSI's 8.8L V8 is one of the most widely deployed industrial spark-ignition engines in the 100-200 kW NG genset class:
Purpose-built for gaseous fuel — not a converted automotive or marine engine
Turbocharged-aftercooled for power density at moderate displacement
Catalytic-converter compatible for additional emissions control on sites that need it
Rated for stationary emergency standby under EPA 40 CFR 60 Subpart JJJJ
The same 8.8L PSI block underpins competitive units from Generac Industrial, Kohler, Gillette, and others — meaning service literature and parts availability are broad.
The PSI 8.8L is a platform we service across multiple brands, 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 Basler DGC-2020 controller is straightforward to interrogate locally and remotely. As with the rest of the Blue Star line in our market, the main consideration is dealer access: we recommend customers stock primary service items on-site rather than relying on next-day local availability.

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 engine in the PS150-01?
PSI's 8.8L turbocharged-aftercooled V8 (designation 8.8LTCAC). Power Solutions International is a US engine manufacturer that specializes in stationary spark-ignition engines for the genset market — the same 8.8L V8 platform appears in competing units from Generac Industrial, Kohler, and Gillette. Compression ratio is 10.1:1 and the engine is rated approximately 261 HP (195 kWm) at 1800 RPM in this application.
Why use a turbocharged spark-ignition engine on natural gas?
At 150 kW continuous output, naturally-aspirated NG engines start to require very large displacement to deliver the rated power, which adds weight and cost. Turbocharging with charge-air cooling lets the 8.8L V8 produce 150 kW reliably at 1800 RPM. The trade-off: a few extra service items (turbo bearings, charge-air cooler hoses) versus a naturally-aspirated unit at the same kW.
Can the PS150-01 run on LPG (propane) as well as natural gas?
Yes — the unit is configured for natural gas / LP / dual-fuel operation. PSI's 8.8L spark-ignition platform handles both fuels with a fuel-system swap or dual-fuel regulator. LP standby kW is typically slightly lower than NG due to lower volumetric energy density of propane vapor; confirm the LP rating on the specific spec sheet.
How does the PS150-01 compare to a Kohler KG125 or KG200?
The Kohler KG125 (125 kW NG) and KG200 (200 kW NG) bracket Blue Star's 150 kW PS150-01. Kohler uses its own KG6208THD V8 (6.2L) on the KG125 and a 14.6L V8 on the KG200. Blue Star's PS150 uses the PSI 8.8L V8. The engineering trade-offs are similar; differences come from integrator packaging, controller (DSE 7320 on Kohler vs Basler DGC-2020 on Blue Star), and dealer network.
