Blue Star NG300-01
300 kW standby / 260 kW prime · Natural Gas / LPG · Liquid-cooled
300 kW natural gas / LP standby generator from Blue Star Power Systems. PSI 14.6L turbocharged V8, DSE DCP7310 controller, structural steel base, three-phase 208-600V.
The Blue Star NG300-01 is a 300-kilowatt natural gas / LP standby generator powered by the PSI 14.6L V8. It is rated 300 kWe standby / 260 kWe prime on natural gas (200 kWe standby on LP). The NG300-01 shares the same engine platform, structural steel base, and physical footprint as the NG265-01, extracting an additional 35 kWe from the same 456 bHp powerplant. At this power level, single-phase output is not offered — the NG300-01 is three-phase only.
The same 891 cu in V8 that powers the NG265-01 at 265 kWe delivers 300 kWe in the NG300-01 through higher loading of the 456 bHp engine. Key specifications:
The NG300-01 and NG265-01 share the same engine, base, and enclosure dimensions, making parts and service procedures interchangeable. Confirm gas supply infrastructure can support the 3-inch NPT inlet and 3,269 ft³/hr peak NG consumption before installation — this is a meaningful step up from the 2-inch inlet on the NG200-01.

Estimate runtime on this tank
Fuel demand at 75% load
3,150,000 BTU/hr≈ 3150.0 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 NG300-01?
The Blue Star NG300-01 is rated 300 kWe standby on natural gas (200 kWe on LP) at 60 Hz / 1800 RPM. The PSI 14.6L V8 produces 456 bHp (340 kWm) at standby — the same engine used in the NG265-01 but tuned for 300 kWe output. The prime-rated variant is the NG300-01P at 260 kWe on natural gas.
What engine powers the NG300-01?
The PSI 14.6L V8 — an 891 cu in (14.6L) turbocharged-aftercooled eight-cylinder engine (5.04-inch bore x 5.59-inch stroke, 10.5:1 compression). The NG300-01 uses the same engine family as the NG265-01; the additional 35 kWe of output comes from higher loading of the same 456 bHp powerplant.
Does the NG300-01 offer single-phase output?
No. The NG300-01 is three-phase only, available in 208V, 240V, 480V, and 600V configurations. Single-phase 240V is not offered at this power level. The NG265-01 and below include a single-phase 240V option.
What alternators does the NG300-01 use?
For 208V and 240V three-phase, the Stamford S4L1D-E41 (12-lead WYE and DELTA respectively). For 480V three-phase, the Stamford S4L1D-D41. For 600V three-phase, the Stamford S4L1S-D4. All carry 125°C standby temperature rise and ±0.5% voltage regulation.
How does LP consumption compare between NG265-01 and NG300-01?
LP fuel consumption at 100% standby load is identical between the NG265-01 and NG300-01 at 933 ft³/hr — both use the same engine with the same LP calibration. The difference in NG output (265 vs 300 kWe) comes from higher natural gas energy density utilization.
