Blue Star NG150-01P
150 kW standby / 125 kW prime · Natural Gas / LPG · Liquid-cooled
125 kW prime-rated natural gas / LP generator from Blue Star Power Systems. PSI 8.1LT inline-six, DSE DCP7310 controller, 208-600V, continuous prime duty.
The Blue Star NG150-01P is the prime-rated variant of the NG150-01, rated 125 kWe continuous on natural gas (95 kWe on LP). It is built on the same PSI 8.1LT inline-six platform as the standby NG150-01 and shares an identical physical footprint. The "-P" suffix designates prime-continuous duty: unlimited hours per year at rated load, backed by a 1-year / 1,500-hour prime warranty.
Service intervals and parts cross-references are identical to the NG150-01. The primary difference at service is the prime-duty hour accumulation — plan for more frequent oil and spark plug changes relative to a standby unit that runs infrequently. PSI recommends confirming service intervals with their published prime-duty maintenance schedule when the generator is used for continuous operation.

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 difference between the NG150-01 and NG150-01P?
The NG150-01 is the standby-rated variant at 150 kWe on natural gas. The NG150-01P is the prime-rated variant of the same physical unit, rated 125 kWe continuous on natural gas (95 kWe on LP). Prime rating allows unlimited hours of operation per year at rated load; standby rating is for infrequent emergency use only. Both units use the identical PSI 8.1LT engine and share the same physical footprint and weight.
What is the prime rating of the NG150-01P on natural gas vs LP?
The NG150-01P is rated 125 kWe prime on natural gas and 95 kWe prime on LP (propane). The LP rating is lower due to LP's different BTU content and combustion characteristics. Both fuels require 11 in. water column inlet pressure at the 1.5-inch NPT connection.
What warranty covers the NG150-01P?
Blue Star covers the NG150-01P with a 1-year / 1,500-hour prime warranty, as specified on the OEM spec sheet. The standby variant (NG150-01) carries a 2-year / 2,000-hour standby warranty.
What controller does the NG150-01P use?
The DSE DCP7310 digital control panel — identical to the standby NG150-01. It provides CAN Bus J1939 ECU communications, 8 programmable inputs, 10 contact outputs, RS485, NFPA 110 Level 1 compatibility, and IP 65 ingress protection.
