Overview#
The Blue Star VD275-01 is a 275-kilowatt EPA Tier 3 diesel standby generator built around the Volvo Penta TAD853GE — the highest-output variant of the 7.7L inline-six engine family. It tops the TAD851-853GE range, sitting above the VD250-03 (250 kW) and VD230-01 (230 kW). This is a current-production active model.
Blue Star Power Systems, Inc. is a Minnesota-based generator-set integrator acquired by DEUTZ AG in August 2024. Like other current-production models, the VD275-01 uses the updated component platform: DSE DCP7310 controller and Stamford alternator.
The Volvo Penta TAD853GE platform#
The TAD853GE is the peak-output variant of Volvo Penta's 7.7L industrial diesel family:
- Same 7.7L displacement as the TAD851GE (VD230-01) and TAD852GE (VD250-03) — identical bore, stroke, and compression ratio (17.5:1)
- Highest output tuning — 419 HP vs 397 HP (TAD852GE) and 364 HP (TAD851GE), achieved through increased boost and fueling
- 94% generator efficiency (per Volvo Penta rating) — the highest of the three TAD variants
- Same altitude deration as the VD250-03 — rated power available only up to 1,640 ft (500 m). For higher-altitude sites, the VD230-01 (4,921 ft ceiling) is the safer choice.
Variant selection guide#
The VD275-01 fills the gap between Blue Star's 250 kW and 300 kW offerings:
- VD250-03 (250 kW, Volvo TAD852GE) — 25 kW less from the same 7.7L block. Choose this if the load study shows peak demand under 250 kW.
- VD300-01 (300 kW, Volvo Penta) — next step up, moving to a larger-displacement Volvo Penta engine. Choose this if 275 kW is marginal for the load study.
- VD230-01 (230 kW, Volvo TAD851GE) — same block, 45 kW less, but holds its rating to nearly 5,000 ft elevation. The conservative choice for sites above 1,640 ft.
For sites requiring Tier 4 Final emissions (California new installations, non-emergency prime), consult Blue Star for the closest Tier 4 equivalent in this kW class.
When to spec the VD275-01#
- 220-275 kW continuous emergency standby loads on diesel fuel at sites below 1,640 ft elevation
- Mid-to-large commercial facilities: full-service hotels, large retail, school campuses, municipal buildings
- Sites where Tier 3 emissions are permitted (most US jurisdictions for stationary emergency standby)
- Load studies where 250 kW (VD250-03) is marginal but 300 kW (VD300-01) is oversized
- Competitive bids against Kohler, Cummins, and Generac units in the 250-300 kW class
