BUY New & Used Commercial Backup Generators 1900kW-1999kW GENERATORS FOR SALE

Industries That Use 1900 kW to 1999 kW Generators

A load study that lands in the 1,900s usually comes from a facility that has already counted every building, line, and motor it must keep running. The buyers below tend to arrive with a number, not a guess, and the open question is whether to buy right at it or round up.

• Data centers: Enterprise halls that have outgrown a 1500 kW frame but don’t need a paralleled plant, where the critical load plus cooling comes in just below 2 MW.
• Hospitals: Campus expansions where a new wing pushes an existing essential load past what the old set carried, and the replacement has to cover the whole list at once.
• Water districts: Treatment plants and large pump stations, where several big motors set the figure and the margin above them is what keeps a pump start from tripping the rest.
• Universities and campuses: Central plants serving a cluster of buildings from a single machine, sized zone by zone until the total sits under 2,000 kW.
• Airports: Terminal and airfield loads with backup written into regulation, where the set has to carry everything on the essential bus together.
• Oil and gas processing: Plant and field sites with long-hour duty, the one place in this band where the prime or continuous rating matters more than standby.
• Heavy manufacturing: Plants with large compressors, presses, or chillers, where the starting step of the biggest motor pushes a 1,700 kW running load toward 2 MW.

Sector-by-sector sizing guidance lives on our industries served pages.

1900 kW to 1999 kW Generators at a Glance

• Apparent power: 2,375 to 2,499 kVA at 0.8 power factor.
• Current at 480V: our chart has no row in this band; it lists 2,640 A at 1750 kW and 3,015 A at 2000 kW, and the calculated figure is about 2,857 A at 1900 kW and 3,006 A at 1999 kW.
• Diesel burn at full load: between the chart’s 124.2 gal/hr at 1750 kW and 141.9 gal/hr at 2000 kW.
• Weight on either side: 28,443 lb wet for an open Kohler KD1500 just below the band, 47,523 lb for an open mtu DS2000 just above it.
• Supply: nothing listed inside the band right now, against nine units listed at exactly 2000 kW.
• What decides it: your average load against the rating you buy, and whether the last 100 kW is worth the extra current and fuel.

Nothing Listed Between 1900 kW and 1999 kW Right Now

The inventory panel above shows no units in this band today. That isn’t unusual: large standby sets tend to be built at round outputs, and what we list clusters at 1500 kW and 2000 kW rather than in between. The nearest stock is just above the band, on our 2000 kW generators page:

Every one of those is a Tier 2 diesel, and none of the used sets has reached 650 hours. Just below the band, the 1500 kW generators page carries used Cummins DQGAB, Caterpillar 3512C, and Detroit Diesel / MTU 1500DSEB sets. For everything below 2 MW in one view, see the 1500kW – 1999kW range.

The Spec Sheets That Bracket the Band

No sheet we work from is rated inside 1900 to 1999 kW, so these four show what sits on each side of it:

The Jenbacher J612 is the only sheet here whose range reaches past 1999 kW without being a 2000 kW diesel. It’s offered from 480V up to 13.8kV, and Jenbacher notes its data depends on gas quality and ambient conditions, so get flow and inlet pressure from the sheet for the specific engine you are quoted. For emergency standby the practical comparison is the two diesels: going from the KD1500 to the DS2000 raises full-load burn by about 37 gal/hr and current at 480V from 2,256 A to 3,007 A on the makers’ own sheets.

Fuel Rows at 1750 kW and 2000 kW

Our diesel fuel consumption chart steps in 250 kW increments and has no 1900 kW row. A set in this band burns somewhere between these two lines:

The gap between the two rows at full load is 17.7 gal/hr. Over 24 hours, that is about 2,981 gallons at 1750 kW against about 3,406 gallons at 2000 kW, so a set in the 1,900s needs a tank sized near the upper figure for the same runtime. mtu’s sheet for the DS2000 lists 143 gal/hr at full standby load, within about a gallon of the chart’s 2000 kW row, and names #2 diesel or HVO as the recommended fuel.

What matters more than nameplate burn is what the set burns at your actual load. A 2000 kW set carrying 1,900 kW is running at 95% of its rating, and the chart and sheets put its consumption close to the full-load figure, not the 3/4 one.

Amps at 480V, 600V, and 4160V Around 1900 kW

The two nearest rows on our generator amperage chart, three-phase at 0.8 power factor, with the band’s endpoints calculated from kVA because the chart has no row for them:

The chart marks 208V and 220V unavailable at both rows, so 480V is the lowest practical voltage here. Moving from 1900 kW to 2000 kW adds roughly 158 A at 480V but only about 18 A at 4160V, which is why the step up is an easy decision on a medium-voltage site and a harder one on a low-voltage switchboard that was laid out around the smaller figure. mtu’s DS2000 sheet gives 3,007 A at 480V and 347 A at 4,160V, in line with the chart. Our power calculators will turn your load list into a current figure at your own voltage.

Is the Last 100 kW Worth Crossing 2 MW For?

Usually yes, unless your switchgear, fuel system, or pad was designed around the smaller set.

Buy inside 1900 to 1999 kW when you are replacing a set of that size into an existing installation and the breaker, cable, tank, and pad are already built for it, or when a spec or permit names the output. In that case matching what is there is cheaper than re-engineering around 2000 kW. Step up when the installation is new or being rebuilt anyway, when the load study has no margin left once the largest motor start is included, or when you want the wider choice of new and used units that 2000 kW offers. Altitude and sustained heat both cut available output, so a site that is hot or high should be checked against the derated figure before you settle on a number in the 1,900s.

Standby Headroom: Average Load Against the Rating

If your facility runs near 1,900 kW for long stretches, a 2000 kW standby rating may not cover it, so compare on prime or continuous ratings instead.

Standby ratings come with conditions. mtu limits the DS2000’s standby rating to an average output of no more than 85% across a 24-hour period and allows no overload, which caps the average at 1,700 kW on a 2000 kW set. A load that averages in the 1,900s during an extended outage sits above that line even though it is under the nameplate. Kohler’s KD1500 sheet shows the same gap from the other side of the band: its prime figure at 480V is 150 kW under its 1500 kW standby rating. Ask for the prime or continuous figure on any set you consider here, and size against that if the generator will carry load for days rather than hours. Diesel units are under industrial diesel generators and sets built for fixed backup duty under industrial standby generators.

Why a 2000 kW Set Is Often the Easier Buy

Because that is where the supply is, new and used.

We have nine units listed at exactly 2000 kW from four makers, including used sets with 150 to 645 hours and new Cummins C2000D6E and DQKAB units, while nothing is listed inside this band. Hold out for 1,950 kW and you are choosing from whatever turns up. Accept 2000 kW and you can usually weigh a low-hour used frame against new stock. The trade is fuel and current: the chart’s full-load row climbs 17.7 gal/hr from 1750 kW to 2000 kW, and a 2000 kW set carries roughly 158 A more at 480V than a 1900 kW one, which matters only if the installation can’t absorb it. If cost is the obstacle, our generator financing options spread the purchase, and our rental side, Stag Power Rentals, can bridge the gap while the permanent set is sourced.

Running a Larger Set Below Its Rating

A 2000 kW set at partial load burns about what a smaller set burns at full load, so stepping up costs little in fuel when your load sits well below 2 MW.

The makers’ sheets show it directly. mtu lists the DS2000 at 106 gal/hr at 75% of its standby rating, or 1,500 kW, while Kohler lists the KD1500 at 105.9 gal/hr carrying the same 1,500 kW at full load. At half load the DS2000 burns 74 gal/hr. The caution runs the other way: a diesel that spends long periods lightly loaded can build up unburned fuel in the exhaust, so a 2000 kW set bought for a 1,200 kW load is a different problem from one bought for 1,950. Exercise it under real load or with load bank testing on a schedule.
