Two thousand kilowatts is where used-generator buying gets serious. We stock 118 units at this rating right now, and almost every one of them comes from a hospital, a Tier I or Tier II data center, a paralleled prime-power install, or a large process plant that decommissioned a building. The buyer at this size isn't shopping — they're sourcing. Most calls we take on a 2000 kW unit are from a facilities engineer or an EPC who already has the spec, the switchgear plan, and the pad poured. They want to know hours, tier, alternator condition, and whether we can ship before their commissioning window closes.
The four engine platforms that actually hit 2000 kW standby in a single skid are the Caterpillar 3516 family (B HD and C HD with the older DITA topping out around 1850 kW), the Cummins QSK60 in DQGAA and DQKAB ratings, the Kohler 2000REOZMD (which is an MTU 16V4000 G23 under the enclosure with Kohler's Decision-Maker controls), and the stand-alone MTU 16V4000. We've sold all four. The 3516B and the QSK60 dominate the older fleet — both are 25-year platforms with parts support that's still strong. The 2000REOZMD and the MTU 16V4000 stand-alone are the modern Tier 2 / Tier 4 picks.
Pricing in our inventory runs roughly $135K for an older 3516B with high hours and a beat-up enclosure, up to $650K for a low-hour Tier 4 Final 16V4000 with a sound-attenuated package and integrated paralleling controls. The middle of the bell curve — a 2010-era 3516B HD with 800 hours, factory-rebuilt alternator, indoor or weather-protective enclosure, complete maintenance records — clears at $275K to $400K depending on aftertreatment status and switchgear inclusion. We have a Kohler 2000REOZMD in stock right now (unit GS4806) that fits this profile.
The conversation we have most often at 2000 kW is single-engine vs. paralleled. A buyer evaluating this size is usually also pricing 2× 1000 kW or 2× 1250 kW. We'll walk through the trade-offs honestly — single-engine is simpler, cheaper to install, and easier to service, but you have a single point of failure. Paralleled gives you N+1 redundancy and partial-load efficiency, but the switchgear adds $40K-$80K and the install gets messier. For data centers chasing Uptime Institute Tier III or IV, paralleled wins. For most other applications at this size, the single 2000 kW unit is the right answer. Call us at (818) 484-8550 — we ship from Santa Clarita to anywhere in North America and we've moved enough 2000 kW iron to know what works.

Two thousand kilowatts is the threshold class for serious backup power. Below 1500 kW you're in the world of mid-size hospitals, suburban data centers, and large commercial buildings — there are dozens of engine platforms competing in that range. Above 2500 kW you're into 20-cylinder territory: CAT 3520, Cummins QSK78, MTU 20V4000 — the heavy-industrial and utility-scale class where most buyers parallel multiple smaller engines instead. The 2000 kW slot sits at the upper limit of what a single 16-cylinder engine can deliver in a standard skid, and that's exactly why it became the standard for full-Tier data center modules and Class A hospital campuses.
The engineering reality: a CAT 3516 and a Cummins QSK60 are both V16 engines displacing roughly 60 liters, both designed in the 1990s and refined continuously since, both rated for 30,000+ hours of service life with disciplined maintenance. They are the workhorses of the 2000 kW class. The Kohler 2000REOZMD is the same idea executed differently — Kohler put MTU's 16V4000 G23 (built by Rolls-Royce Power Systems) under their enclosure with their own switchgear and Decision-Maker 6000 controls. That gives Kohler a 2000 kW product without designing their own V16, and it gives buyers MTU's German-engineered durability with Kohler's North American service network.
What separates 2000 kW from anything smaller is the switchgear. At 480V three-phase, a 2000 kW load draws roughly 3,000 amps continuous. That means 2500A or 4000A breakers, paralleling switchgear if you have multiple sources, and an Automatic Transfer Switch sized correctly for the inrush. The unit price of the generator itself is often less than half the project cost — switchgear, fuel storage, controls integration, exhaust, and intake/cooling all scale up. We sell the iron, but we'll talk through the rest of the project with you because we've seen what gets missed.
We hold 118 generators rated at exactly 2000 kW across CAT 3516, Cummins QSK60, Kohler 2000REOZMD, and MTU 16V4000 platforms. That is one of the largest concentrated 2000 kW inventories in North America, all stored at our Santa Clarita, CA facility.
Tier 4 Final at this size requires SCR / DEF aftertreatment that adds $30K to $60K to a unit. We stock both — Tier 2 for off-road and prime-power applications where it is permitted, Tier 4 Final for California, New York, and any new permit-required install.
At 2000 kW the difference between a $185K unit and a $385K unit is hours, oil sample history, and load-bank documentation. Every unit we list shows hours from the controller readout, and where the seller provided records we forward them to you in full.
We sell single 2000 kW skids for buyers who want simplicity, and we sell pairs (2x 1000 kW or 2x 1250 kW) for buyers who need N+1 redundancy. Tell us your application and we will tell you honestly which approach fits your project budget and uptime requirement.
Most of our 2000 kW inventory came out of decommissioned hospital campuses or data center buildings being repowered. These units were maintained on Joint Commission or Uptime Institute schedules. The maintenance paper trail is what holds value at this size.
A 2000 kW skid weighs 35,000 to 50,000 lbs depending on enclosure and fuel tank. We coordinate flatbed or RGN transport from Santa Clarita to any continental US destination, and we handle export paperwork for international buyers.
Range in our inventory is $135K to $650K. The variables that move price most: hours on the engine (under 500 vs. over 2000), emissions tier (Tier 2 vs. Tier 4 Final, the latter adds $30K-$60K of aftertreatment), enclosure type (open skid, weather-protective, sound-attenuated Level 2 or Level 3), and whether the unit includes a paralleling switchgear lineup or just the genset itself. A typical 2010-era CAT 3516B HD with 800 hours and a sound-attenuated enclosure clears at $275K to $400K.
Honest answer: it depends on your service network. The CAT 3516B is the most common 2000 kW engine in the world and parts are available everywhere. The Cummins QSK60 has a slightly stronger oil-and-gas service footprint. The MTU 16V4000 (whether stand-alone or under a Kohler 2000REOZMD enclosure) is the modern engineering choice — quieter, cleaner, and built for continuous duty — but the dealer network is thinner outside major metros. If you have a CAT dealer five miles away and you are sizing for emergency standby, buy the 3516. If you have an existing MTU fleet, stay MTU.
Single 2000 kW wins on capex, footprint, and install simplicity. You save $40K to $80K in switchgear and you only have one set of fuel lines, one exhaust stack, one cooling package. Paralleled 2x 1000 kW wins on redundancy — you can take one offline for maintenance without losing capacity, and a single engine failure does not take down the whole load. Data centers chasing Uptime Tier III or IV essentially require parallel because they need concurrent maintainability. Most hospitals at 2000 kW go single-engine because NFPA 110 only requires one transition path.
It is an MTU 16V4000 G23 engine with a Kohler-branded enclosure, Kohler Decision-Maker 6000 controls, and a Kohler-spec alternator. Kohler does not manufacture a V16 in-house — they partner with Rolls-Royce Power Systems (which owns MTU) for their largest units. The 2000REOZMD gives you German engine engineering with Kohler North American service support. We have one in stock right now (unit GS4806).
It depends on your jurisdiction and application. In California, any new permitted standby install that runs more than the limited-use exemption hours per year typically needs Tier 4 Final. SCAQMD, BAAQMD, and SJVAPCD all push hard on this. Tier 4 Final at 2000 kW means SCR with DEF (urea) injection plus a DPF — that is real capex (the aftertreatment package alone runs $40K-$80K) and real opex (DEF refills, DPF regens). Outside California, Tier 2 is often acceptable for emergency-only standby. We stock both. Tell us your AHJ and your run-hours profile and we will tell you what you actually need.
A CAT 3516B or Cummins QSK60 with documented oil-sample history and disciplined maintenance will run 25,000 to 35,000 hours before a major in-frame overhaul. We see units that came out of standby service with 800 to 3000 hours — those have decades of useful life left. Continuous-prime-power units coming off oil-and-gas sites can show 15,000+ hours and still be solid buys for backup duty, where they will see less than 100 hours per year.
A 2000 kW diesel at full load burns roughly 130-150 gallons per hour. NFPA 110 requires Level 1 systems to have enough fuel for the full classified runtime — typically 8 hours minimum, sometimes 24, 48, or 72 hours for hospitals and data centers. A 24-hour bulk tank at 2000 kW is around 3,500 gallons. Day tanks are usually 100-200 gallons with auto-fill from the bulk tank. Plan the fuel system before you buy the generator — it is a significant fraction of total project cost.
Yes. We ship from our Santa Clarita, CA yard nationwide. A 2000 kW skid with sound-attenuated enclosure typically weighs 40,000 to 50,000 lbs and ships on a flatbed or RGN trailer. Permits are required for over-dimensional or over-weight loads in most states. We coordinate the freight or you can arrange your own. Lead time from order to truck-out is usually 7-14 days depending on inspection scope. International export from Long Beach is also routine for us.
Most of our 2000 kW units are sold genset-only. Some come with their original paralleling switchgear if the seller decommissioned the whole lineup together. CAT EMCP 4.4 or 4.5, Cummins PowerCommand 3.3 or 3.6, MTU MGC 3000, and Kohler Decision-Maker 6000 are the four most common controllers we encounter — all support paralleling natively. If you need switchgear we can quote ASCO, Russelectric, or Cummins PowerCommand lineups separately.
Yes. We buy used generators across all sizes, and 2000 kW units with documented hours and maintenance records hold the strongest residual value of anything in the industrial generator market. If you are upgrading from an older 3516 or QSK60 to a Tier 4 Final replacement, call us before you scrap the old unit — we have routinely paid $35K to $95K for units that contractors quoted at scrap-metal value.
CAT 3516, Cummins QSK60, Kohler 2000REOZMD, and MTU 16V4000 — we have all four platforms on the yard right now. Hours, photos, maintenance records, and freight quotes available within 2 business hours. Call (818) 484-8550 or use the form. We ship from Santa Clarita to anywhere in North America.
