Overview#
The Blue Star PD100-01 is a 100-kilowatt Tier 3 diesel standby generator powered by the Perkins 1104D-E44TAG2, a 4.4-liter electronically injected turbocharged and charge-air-cooled four-cylinder engine — pushed to its peak standby output. It shares the 90×44 in equipment pad with the PD80-01, making it a direct power upgrade for sites where 80 kW is insufficient.
Blue Star Power Systems (North Mankato, Minnesota) pairs the 1104D-E44TAG2 with a Stamford UCI274C alternator (stepping up from the UCI224 frame to the 274 frame) and DSE DCP7310 controller. At 2,500 lbs, the PD100-01 is only 75 lbs heavier than the PD80-01, meaning equipment rooms designed for either model can accept the other without structural modification.
The 1104D-E44TAG2 at Peak Output#
At 100 kWe, the 1104D-E44TAG2 is running at its peak rated standby capacity for this configuration. The engine's thermal profile is identical to the PD80-01 — same coolant heat rejection, same exhaust conditions — because the added load is absorbed by the larger alternator rather than increased engine output. This means the 100 kWe rating is achieved through a higher-rated generator rather than a fundamentally different engine calibration, and the engine service experience mirrors the PD80-01 closely.
When to spec the PD100-01#
- 80–100 kW emergency standby loads on diesel fuel
- Sites with an established 90×44 in equipment pad upgrading from 80 kW
- Light-industrial, commercial, and municipal applications with Tier 3 acceptance
- Competitive bids against a Kohler 100REOZK or Cummins C100D6 on a Perkins-powered option
Our service experience#
Because the PD100-01 runs the 1104D-E44TAG2 near its peak output, we recommend load bank testing at commissioning and at each annual service. Fuel consumption at 75% load (6.24 gph) compared to full load (7.64 gph) shows good load efficiency; the unit performs well at partial load. Follow the Perkins 1100D generator series service schedule and inspect the intercooler connections annually.
