A popular size for mid-sized commercial and light industrial sites

A 200kW generator backs up a whole mid-sized building, HVAC included. It’s a common pick for schools, nursing homes and assisted living, big-box and grocery stores, large office buildings, cold storage rooms and light manufacturing. It’s also a popular rental size for construction sites and events.

Our 200kW stock changes week to week. It usually runs from brand-new units to used standby sets from Generac, Olympian, Kohler, Multiquip and others, almost all diesel.

Every unit is ours. We buy and own our inventory outright, so we can tell you where a generator came from, how it was used and what our technicians found when they went over it. Units ship from our yards in Brighton, Jacksonville, Pensacola and Austin, and we can get them to a site anywhere in the contiguous US, with Canada and Mexico on request.

What a 200kW generator can power

Typical buyers include:

• Commercial buildings: large offices, schools, big-box retail and grocery stores
• Healthcare: nursing homes, assisted living facilities, surgery centers and large clinics
• Industrial: machine shops, light manufacturing, cold storage and distribution
• Municipal: lift stations, water booster stations, and police and fire stations
• Agriculture: irrigation pumps, and poultry and dairy operations

Size for starting loads, not just running loads. Rooftop HVAC units, compressors and pumps pull several times their running current for a moment when they start, and that is usually what decides whether 200kW is enough.

200kW generator specs

A 200kW standby generator is rated at 250kVA. Amps are three-phase at a 0.8 power factor, from our kVA, kW and amperage chart. Most 200kW sets run at 480V or 208V.

Voltage (three-phase)	Amps
208V	694
240V	601
480V	301
600V	241

Fuel use below is estimated from our fuel consumption charts. Actual use depends on the engine and site conditions.

Load	Diesel (gal/hr)	Natural gas (ft³/hr)
1/4	4.7	952
1/2	7.7	1,500
3/4	11.0	2,066

Before a unit ships we can put it on a load bank so you can see it carry load. Our YouTube channel has load bank runs on generators across the size range.

200kW generator FAQ

How many amps does a 200kW generator put out? At three-phase and a 0.8 power factor, a 200kW generator delivers about 301 amps at 480V, 241 amps at 600V, 601 amps at 240V and 694 amps at 208V. Your electrician will size the breaker and transfer switch from those numbers.

How much fuel does a 200kW generator use? A diesel 200kW unit burns roughly 7.7 gallons an hour at half load and 14.4 at full load. At three-quarter load that is about 264 gallons over 24 hours. On natural gas, figure about 1,500 cubic feet an hour at half load and 2,583 at full load.

Is a 200kW generator the same as 250kVA? Yes. Generators are usually rated at a 0.8 power factor, so 200kW of real power equals 250kVA. You’ll see both numbers on spec sheets and nameplates.

What’s the difference between a standby and a prime rating? A standby rating is for backup power during outages. A prime rating is for running as the main power source for long stretches, and it’s often around 10% lower, so a 200kW standby set may carry about 180kW prime. Check the spec sheet for each unit.

Can two smaller generators do the job of one 200kW unit? Yes. Two 100kW units paralleled through switchgear can share a 200kW load and give you redundancy if one goes down for service. The trade-off is the cost and complexity of the paralleling controls. We can help you compare both setups.

Should I buy new or used? Used units cost less and are often ready to ship now, while new units can carry a factory lead time. We stock both. Every used unit lists its hours and year, and we’ll send photos and a walkaround video of the actual generator before you commit.

How much does a 200kW generator cost? Price depends on whether it’s new or used, its hours, brand, fuel type and enclosure. Tell us about your site and we’ll send pricing on every 200kW unit that fits.

Can I rent a 200kW generator instead? Yes. Our rental teams in Colorado, Florida and Texas can set you up for a short-term job, an event or while you wait on a permanent unit. See generator rentals.
