Blue Star NG650-01P
650 kW standby / 550 kW prime · Natural Gas / LPG · Liquid-cooled
550 kW prime-rated natural gas / LP generator from Blue Star Power Systems. PSI 32L V12 turbocharged-aftercooled, DSE DCP7310 controller, three-phase 208-600V.
The Blue Star NG650-01P is the prime-rated variant of the NG650-01, delivering 550 kWe continuously on natural gas (350 kWe on LP). It uses the identical PSI 32L V12 platform and physical enclosure as the standby NG650-01. Three-phase only — no single-phase option. The NG650-01P carries a 1-year / 1,500-hour prime warranty.
Service procedures are identical to the NG650-01 standby. Prime-duty use means higher annual hour accumulation on the V12 — plan for more frequent spark plug and ignition coil service intervals per PSI's prime-duty schedule.

Estimate runtime on this tank
Fuel demand at 75% load
6,825,000 BTU/hr≈ 6825.0 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 prime rating of the NG650-01P?
The Blue Star NG650-01P is rated 550 kWe prime on natural gas and 350 kWe prime on LP at 60 Hz / 1800 RPM, backed by a 1-year / 1,500-hour prime warranty. The paired standby unit is the NG650-01 at 650 kWe standby NG / 400 kWe standby LP.
How does fuel consumption compare between NG650-01 and NG650-01P?
At 100% load: NG650-01 standby consumes 7,259 ft³/hr NG (650 kW); NG650-01P prime consumes 6,268 ft³/hr NG (550 kW). LP at 100% prime is 1,900 ft³/hr vs. 2,177 ft³/hr at standby.
What are the deration thresholds for the NG650-01P?
The NG650-01P prime uses 87°F inlet air and 3,000 ft altitude as deration start points. This differs from the standby NG650-01 which uses the standard 77°F / 1,200 ft. The prime variant's better deration tolerance reflects the lower continuous load relative to engine capacity.
Is single-phase output available on the NG650-01P?
No. The NG650-01P is three-phase only, in 208V, 240V, 480V, and 600V configurations.
