BUY New & Used Commercial Backup Generators 2000kW-2299kW GENERATORS FOR SALE

Industries That Use 2000 kW to 2299 kW Generators

Buyers at two megawatts are rarely covering one building’s emergency panel. They are covering a whole site, or one leg of a redundant plant, and the load study behind the purchase is usually shared between the owner, an electrical engineer, and the utility before anyone picks a unit.

• Data centers: Colocation and enterprise halls where the uptime terms written into customer contracts decide how many independent 2 MW units sit on the pad, not just their combined output.
• Hospitals: Medical campuses that want one machine large enough to carry life-safety and critical loads across several wings, with transfer timing set by code.
• Universities: Central plants backing labs, residence halls, and research freezers across a campus from a single generator yard.
• Oil and gas: Terminals and processing facilities where the set may carry operating load for long stretches rather than waiting for an outage.
• Rock crushing and aggregate: Crushing and screening plants running large motors as primary power, where starting the crusher sets the size more than the running total does.
• Water districts: Treatment plants with banks of high-horsepower pumps that have to come back on line in sequence after a utility loss.
• Manufacturing and cold storage: Large plants and refrigerated warehouses where compressors and process motors make this a motor-starting decision before it is a capacity decision.

Our industries served pages carry sizing notes for each sector.

• Weight and footprint: 47,523 lb and 254.9 x 99.9 x 135.2 inches for mtu’s open DS2000, before any enclosure or tank.
• Cooling air and noise: 111,890 SCFM through the DS2000 radiator at its 50 °C rating, and 98.7 dB(A) at 7 m with the set open.
• What we list: diesel standby sets certified to EPA Tier 2, built at exactly 2000 kW, most of the used ones under 650 hours.

Every Unit We’ve Listed Here Is a 2000 kW Set

Nothing we have listed in this band has been rated between 2001 kW and 2299 kW. Each unit is a 2000 kW diesel standby set certified to EPA Tier 2:

The hour meters tell the story. The 2007 Cummins DQKAB sets are listed at 150 hours, which averages out to fewer than 10 hours a year, about what routine exercise and the occasional outage add up to. The highest-hour unit on the list, a 2010 Baldor power module, is still under 650. Whatever is on the ground today is in the listings above, and our 2000 kW generators page goes deeper on that single size.

Four Published Sheets Rated at or Near 2 MW

Diesel and natural gas both reach this output. These are the manufacturer figures we reference most for a 2 MW set:

The 2000 kW on each of these sheets means something different. The DS2000 figure is a standby rating, and mtu approves it for an average output of no more than 85% over 24 hours, with no overload capability. The Cummins gas set is rated for continuous duty and needs 2.2 to 6.5 psi at its fuel shutoff valve inlet. Cat’s G3520 accepts 100% block load in one step, which matters when a whole facility transfers at once, and its heat rate at 2000 ekW works out to about 18.2 MMBtu/hr. Jenbacher does not publish gas flow or inlet pressure for the J612 and ties its data to gas quality and ambient conditions, so those numbers have to come from the data sheet for the exact unit.

Diesel Consumption at 2000 kW and 2250 kW

Our diesel fuel consumption chart has two rows inside this band:

mtu’s figures for the DS2000 track the chart’s 2000 kW row closely at every step it publishes: 143 gal/hr at full standby load against 141.9, 106 gal/hr at 75% against 103.5, and 74 gal/hr at 50% against 72.2. mtu names #2 diesel or HVO as the recommended fuel.

Over 24 hours at full load, a 2000 kW set burns about 3,406 gallons by the chart and about 3,432 by mtu’s figure, and a 2250 kW set about 3,830. At half load a 2000 kW unit uses roughly 1,733 gallons a day. Bring those numbers to the tank design alongside whatever runtime your code, your insurer, or your customer contracts require.

Output Current at the 2 MW Mark

Three-phase current at 0.8 power factor, from our generator amperage chart:

mtu’s DS2000 sheet lands within a few amps of the chart, at 3,007 A at 480V and 347 A at 4,160V. The chart marks 208V and 220V unavailable at both sizes, so low-voltage service in this band means 480V or 600V. Our power calculators will turn a load list into a working kW figure before you settle the voltage.

Should a Single 2000 kW Set Run at 480V or 4160V?

Either works at exactly 2 MW, and the answer comes from what the set connects to and how far its power has to travel.

At 480V a 2000 kW set delivers about 3,015 A, so the main breaker, the bus, and the cable runs to the transfer equipment are all built for three thousand amps, with several conductors per phase. At 4160V the same output is about 348 A, roughly a ninth of the current, on far smaller cable, but the alternator, switchgear, and terminations become medium-voltage equipment with their own clearances and testing. A building that already distributes at 480V, with the set near the main switchboard, usually stays low voltage. A campus loop, a medium-voltage substation, or two sets on a common bus usually points to 4160V. mtu gives its DS2000 dimensions for the open 480V unit and notes the length can change at other voltages, so ask for the drawing at the voltage you intend to buy. On the gas side, Jenbacher offers the J612 from 480V up to 13.8kV.

How Many 2 MW Units Does a Data Center SLA Call For?

As many as the redundancy level in the contract requires, which at this size usually means more than one.

2000 kW is the output where the largest data centers stop relying on a single generator. A hall with 2 MW of critical load built to N+1 needs at least one unit beyond what the load needs, so two 2000 kW sets; a 2N design duplicates the whole generator plant. In colocation and hyperscale work, the service levels promised to tenants can dictate the count of independent units as directly as the kilowatt total does, and the generator specification follows the contract. That puts paralleling controls and switchgear into the budget, along with the target transfer time and the largest motor start in the cooling plant. A single 2000 kW set still fits an enterprise hall or any facility whose spec stops short of redundancy. Our data center generator page covers sizing for both cases.

What a 2000 kW Generator Room Has to Move and Muffle

Air and sound, in volumes large enough to shape the room before the generator arrives.

mtu’s DS2000 sits on a structural steel base with a unit-mounted radiator, and at its 50 °C (122 °F) rating that radiator needs 111,890 SCFM of cooling air. Indoors, all of it has to enter through intake louvers and leave through a discharge path without circling back to the radiator face, which fixes the size of the wall openings and any ductwork. Open, the set measures 98.7 dB(A) at 7 m (23 ft) at full standby load, so a room near offices, patient areas, or a property line needs acoustic treatment on those same openings. Outdoors, the choices are a weather enclosure, a sound-attenuated enclosure, a walk-in enclosure, or a container, and each one adds weight and changes the crane pick. On the DS2000, 2021 IBC seismic certification and HCAI pre-approval are optional, which decides how the base is anchored on healthcare and seismic-zone sites.

Is a Low-Hour Used 2000 kW Set Worth Buying?

Often, because a used 2 MW standby unit has usually spent its life waiting between tests, and the hour meter shows it.

Six of the units in the table above are used, with 150 to 645 hours on 2007 to 2015 builds. Low hours alone don’t close the question on a machine like that. Read the service records, ask how the set was stored and exercised, and confirm the control platform will work with your switchgear. Check the rating behind the 2000 kW as well: a standby set that will carry load for long stretches is outside its rating, as mtu’s 85% average limit on the DS2000 makes plain. Every unit we list at this size is Tier 2, the certification these sets carry for stationary emergency service, so confirm that matches your air permit.

New is the right call when a spec requires a factory warranty, current controls, or new equipment outright; mtu’s basic limited warranty on the DS2000 runs two years or 3,000 hours. We carry new Cummins C2000D6E and DQKAB units alongside the used frames, so compare used industrial generators and new industrial generators side by side. To cover a gap while a permanent set is sourced or rebuilt, Stag Power Rentals handles temporary megawatt work, and our generator financing options can keep a purchase on schedule.

Where 2000 kW to 2299 kW Sits Among Nearby Bands

If the study lands just under 2 MW, one set from the band below keeps paralleling gear out of the project. If motor starting or growth pushes past 2,300 kW, move up rather than run a 2000 kW unit at its ceiling.

Our 2000kW – 3000kW generators page covers the whole tier above two megawatts, and shop by kW lists every output we carry.

Inspected, Load Tested, and Backed After the Sale

Every generator we sell goes through a 22-point inspection and load bank testing before it ships, and on a low-hour standby frame that test is what proves it can carry its rated load after years of short exercise runs. We’ve been buying and selling industrial generators for over a decade. Each purchase carries our 30-day IronClad warranty, and our service and maintenance team handles scheduled testing, industrial generator repair, and emergency service once the unit is in place.
