Overview#
The Blue Star PS130-01 is a 130-kilowatt natural gas / LP standby generator built around the PSI 8.8LTCAC V8 — the engine platform used across Blue Star's PS-prefix gaseous units. It is rated 130 kWe standby on natural gas and 125 kWe on LP (the closest LP-to-NG ratio of any Blue Star gaseous model in this range). The PS130-01 is the top of the PS-prefix line below the larger NG-prefix units that begin at 150 kW.
The PSI 8.8LTCAC engine#
The PSI 8.8LTCAC is an 8.8-liter V8 turbocharged-aftercooled spark-ignition engine:
- V8 configuration — 4.35-inch bore × 4.50-inch stroke, 535 cu in displacement, 10.5:1 compression ratio
- 261 bHp (195 kWm) at 1800 RPM standby
- High ambient / altitude tolerance — full output to 122°F inlet air temperature and 4,000 ft altitude before deration begins
- Compact footprint — the V8 package produces the smallest OPU in the 130 kW class
Deration factors: 1.5% per 10°F above 122°F inlet air temperature; 2.5% per 1,000 ft above 4,000 ft altitude.
LP vs. NG parity#
The PS130-01's LP rating of 125 kWe is within 4% of its NG rating of 130 kWe — an unusually small gap for a gaseous genset. This makes the PS130-01 attractive for installations where the fuel supply may switch between natural gas and LP depending on supply conditions or site configuration.
Alternator configurations#
| Voltage | Phase | Alternator | Connection |
|---|---|---|---|
| 120/240V | 1 | Stamford UCI274H | 12-lead DD |
| 120/208V | 3 | Stamford UCI274F | 12-lead WYE |
| 240V | 3 | Stamford UCI274F | 12-lead DELTA |
| 277/480V | 3 | Stamford UCI274E | 12-lead WYE |
| 347/600V | 3 | Stamford UCI274E | 4-lead WYE |
All configurations carry 125°C standby temperature rise and ±1% voltage regulation.
When to spec the PS130-01#
- 100–130 kW standby loads on natural gas or LP
- Hot climate or high-altitude sites where the PSI 8.8L's extended deration thresholds (122°F / 4,000 ft) are required
- Applications where LP and NG output parity matters (125 vs. 130 kWe)
- Projects needing single-phase 240V output at the 130 kW tier
- Where physical footprint is a constraint — the PS130-01 OPU (96 x 54 x 62 in, 2,950 lbs) is substantially more compact than the NG150-01 at the next tier up
Our service experience#
The PSI 8.8L V8 is the most common engine platform across Blue Star's sub-150 kW gaseous line. Spark plugs, ignition coils, and air filters are the primary service items. The 1.5-inch NPT fuel inlet and small oil system (2.00 gal capacity) reflect the compact engine size. Parts availability through PSI's distribution network is generally good for this high-volume platform.
