Overview#

The Blue Star PD300-01 is a 300-kilowatt Tier 3 diesel standby generator powered by the Perkins 1706D-E93TAG2 — the second calibration of the 9.3-liter, six-cylinder turbocharged and charge-air-cooled platform. The PD300-01 shares its engine architecture and 120×66 in footprint with the PD250-01, differing primarily in the TAG2 engine calibration, a slightly heavier alternator (S4L1D-D41 vs S4L1D-C41), and 200 additional pounds on the same structural base.

Blue Star Power Systems (North Mankato, Minnesota) pairs the 1706D-E93TAG2 with a Stamford S4L1D-D41 alternator and DSE DCP7310 controller. At 6,050 lbs and 88 dBA, the PD300-01 is three-phase only — applications requiring single-phase output at this power level should specify the PD250-01 instead. Deration: rated power is available to 3,281 ft (1,000 m) at 104°F (40°C).

The 1706D-E93 at 300 kW#

The TAG2 calibration increases the turbocharger boost and fuel delivery calibration over the TAG1, adding 50 kWe on the same 9.3-liter platform. Ventilation requirements are identical between the PD250 and PD300 (17,032 CFM radiator airflow), making it straightforward to swap or upgrade within the same equipment room. The exhaust temperature steps up from 925°F (TAG1) to 959°F (TAG2), and fuel consumption increases from 19.1 to 22.3 gph at full load.

When to spec the PD300-01#

  • 275–300 kW three-phase emergency standby loads on diesel fuel
  • Facilities where the 120×66 in footprint is established and the PD250 is already installed (same footprint allows footprint-neutral upgrade)
  • Commercial buildings, light-industrial facilities, telecom sites, and pump stations in the 300 kW tier
  • Sites with adequate altitude and ambient temperature headroom (rated to 3,281 ft / 104°F)

Our service experience#

The PD300-01 transitions to 24V battery system (vs 12V on PD20–PD200 models) — verify battery system compatibility during commissioning. Both the PD250-01 and PD300-01 share identical ventilation requirements, which simplifies dual-generator installations or planning for load growth. Follow the Perkins 1700D generator series maintenance schedule, including charge air cooler and turbocharger inspection at recommended intervals.

Estimate runtime for the Blue Star PD300-01

Adjust load percent and tank size to estimate runtime. Pre-filled with this model's spec where available.

Estimate runtime on this tank

Estimated runtime

11.6 hours(0.5 days)

Fuel consumption ≈ 17.20 GPH at 75% load. Estimate based on industry-typical 1800 RPM standby curves (≈0.07 GPH/kW at full load). Actual consumption varies by engine, ambient temperature, fuel quality, and tuning.

Frequently Asked Questions

What engine does the PD300-01 use?
The Perkins 1706D-E93TAG2 — a 9.3-liter, six-cylinder turbocharged and charge-air-cooled diesel. The TAG2 calibration of the 1706D-E93 platform produces 300 kWe standby, one output step above the TAG1 (250 kWe, PD250-01) on the same engine architecture. It carries EPA Tier 3 certification for stationary emergency applications. Rated power is available up to 3,281 ft (1,000 m) at ambient temperatures to 104°F (40°C).
What controller does the PD300-01 use?
The DSE DCP7310 Digital Control Panel, with CAN Bus J1939 engine communication, digital metering, RS-485 interface, 8 programmable contact inputs, 10 contact outputs, and NFPA 110 Level 1 compatibility. The panel is cULus Listed and CE Approved with IP 65 ingress protection (with supplied gasket). A 24V battery system and 24V 5 Amp battery charger are standard.
How does the PD300-01 compare to the PD250-01 and PD350-01?
The PD250-01 (TAG1) and PD300-01 (TAG2) share the same 1706D-E93 engine platform and identical 120×66 in footprint — only 200 lbs separate them (5,850 vs 6,050 lbs). The PD250 supports single-phase output; the PD300 is three-phase only. At 300 kWe, the PD300-01 burns 22.3 gph vs 19.1 gph at full load. The PD350-01 steps up to the larger 2206D-E13 platform (12.5L) on a 140×72 in footprint at 7,875 lbs.
What are the ventilation and thermal requirements for the PD300-01?
The PD300-01 requires 17,032 CFM of radiator cooling airflow — the same as the PD250-01, since both use the same 1706D engine platform and radiator configuration. Combustion air draw is 951 CFM. Heat rejected to the coolant circuit is 466,260 BTU/hr; heat radiated to ambient is 363,960 BTU/hr. Exhaust exits at 959°F at 2,435 CFM. For fuel planning: at full load (22.3 gph), a 1,000-gallon tank provides approximately 45 hours of runtime.
