The Blue Star MD2000-01 is a 2,000-kilowatt Tier 2 diesel standby generator — the top of Blue Star's Mitsubishi diesel product line. It is powered by the Mitsubishi S16R-Y2PTAW2-1, a higher-output variant of the 65.4-liter, 16-cylinder V-configuration S16R platform, producing 2,923 HP at 1800 RPM. At 2 MW, this is a utility-class standby generator used in large data centers, hospital campuses, industrial complexes, military bases, and critical municipal infrastructure.
Blue Star Power Systems (North Mankato, Minnesota; DEUTZ AG subsidiary since 2024) assembles the MD2000-01 on a structural steel base — the same 244×89 in footprint as the MD1600-01, though 14 inches taller at 135 inches — with a Stamford S7L1D-G alternator (480/600V; consult factory for 208/240V) and DSE DCP7310 controller. The 4160V configuration uses a Stamford S9M1D-B4 medium-voltage alternator, distinct from the MVWI series used on the V12 models.
The S16R-Y2PTAW2-1 is the high-output calibration of Mitsubishi's S16R generator engine. Compared to the MD1600-01's S16R-Y2PTAW-1, it achieves 2,923 HP (vs 2,346 HP) through revised fuel system mapping at a slightly reduced compression ratio (14.0:1 vs 14.5:1). This is a pattern also seen between the JD275-02 and JD300-02 in Blue Star's John Deere lineup: the same displacement, different calibration, different output ceiling. The dual intercooler/jacket water cooling system remains identical in architecture to the MD1600-01.
The MD2000-01's 86,078 CFM ventilation requirement and 37,725 lb OPU weight make the equipment room engineering as significant as the generator selection itself. Fuel at 155 gph means a 2,000-gallon tank provides approximately 12.9 hours of runtime at full load. At this power level, fuel logistics, transfer pump sizing, and secondary containment are engineering disciplines in their own right. We recommend an outdoor weather-protective or sound-attenuated enclosure as the default configuration unless the mechanical and structural budget for an indoor installation is already established.

Frequently Asked Questions
What engine does the MD2000-01 use?
The Mitsubishi S16R-Y2PTAW2-1 — a 65.4-liter (3,989 cu in), 16-cylinder V-configuration turbocharged and water/air-intercooled diesel producing 2,923 HP at 1800 RPM for standby use. It shares the bore and stroke (6.69×7.09 in) and displacement with the MD1600-01's S16R-Y2PTAW-1, but uses a different fuel system calibration (indicated by the '-2' suffix) and a lower compression ratio (14.0:1 vs 14.5:1) to achieve 400 kWe more output. EPA Tier 2 certified for stationary emergency standby.
What alternator does the MD2000-01 use?
The alternator selection is voltage-dependent. At 480V (4-lead wye) and 600V (4-lead wye), Blue Star specifies the Stamford S7L1D-G. At 208V and 240V, the specification is 'Consult Factory' — 3,000+ amp single-phase-equivalent configurations require factory engineering at 2 MW. For the 4160V configuration, a Stamford S9M1D-B4 medium-voltage alternator is installed. All are 4-pole, brushless single-bearing units.
What controller does the MD2000-01 use?
The DSE DCP7310 Digital Control Panel — CAN Bus J1939, digital metering, RS-485, 8 programmable contact inputs, 10 contact outputs, cULus Listed, CE Approved, NFPA 110 Level 1 compatible.
How does the MD2000-01 differ from the MD1600-01 if they use the same engine displacement?
Both the MD1600-01 and MD2000-01 use 65.4L S16R engines with identical bore and stroke. The MD2000-01 uses the S16R-Y2PTAW2-1 variant, which has a revised fuel system calibration (the '-2' suffix) and a slightly lower compression ratio (14.0:1 vs 14.5:1) to support higher peak cylinder pressures for the additional 400 kWe output. The MD2000-01 is 14 inches taller (135 in vs 121 in) and 3,275 lbs heavier (37,725 vs 34,450 lbs). Fuel at full load increases from 127 to 155 gph.
What are the ventilation requirements for an indoor MD2000-01 installation?
The MD2000-01 requires 86,078 CFM of radiator cooling airflow — equivalent to a large commercial HVAC system — and 7,274 CFM of combustion air. Heat radiated to the equipment room is 2,349,660 BTU/hr, with an additional 2,662,440 BTU/hr rejected through the jacket water cooling circuit. At 2 MW, an indoor installation is an infrastructure project requiring a dedicated mechanical engineering scope for ventilation, structural pad, and fuel storage. Outdoor installation with a weather-protective enclosure is often more practical at this power level.
