750 kW Generators for Industrial Plants, Mining Operations, Remote Sites, and More

Large industrial facilities, hospitals, data centers and remote areas without utility power are all served by 750 kW generators. The set can run heavy-duty motors, pumps, air conditioning, refrigeration and lighting together, and it also supports construction sites, outdoor events and emergency response.

Neighborhood and Microgrid-Scale Applications

750 kW is large enough to function as more than backup for a single facility — it’s a size that shows up in neighborhood-level emergency response and early-stage microgrid projects, where the generator is effectively acting as a temporary utility for a cluster of buildings rather than one site. This makes it a common size for disaster response planning at the municipal level, and increasingly for facilities experimenting with microgrid resilience ahead of a full renewable-plus-storage buildout.

Choosing 750 kW for Industrial Duty

Sizing 750 kW means reading the load list the way a utility planner would: peak demand, diversity between buildings, and the portion that can never drop. Include the largest motor starts and the growth already planned. Our power calculator is a useful starting point. The amperage chart has no 750 kW row, but its 700 kW and 800 kW rows (3 phase, 80% power factor) list 2,430 A and 2,780 A at 208V and 1,052 A and 1,203 A at 480V. Generac lists 1,129 A at 480V for its 750 kW sets.

Fuel Flow and Gas Pressure Behind a 750 kW Set

Diesel and gas versions of a 750 kW set from the same maker differ in engine size, fuel line, and footprint.

• Diesel: The diesel fuel consumption chart lists a 750 kW generator at 16.3, 27.4, 39.3, and 53.4 gal/hr from 1/4 to full load, as estimates. Generac’s SD750 has an 18.1 L Perkins engine rated 750 kW (938 kVA) standby and 675 kW prime, with the prime rating not available in the U.S. It lists 14.3, 25.6, 38.0, and 49.7 gal/hr at standby, and sub-base tanks of 334 gallons (6 hours), 1,001 gallons (20 hours), or 2,002 gallons (40 hours).
• Natural gas: Generac’s SG750 is a 33.9 L, 12-cylinder set rated 750 kW standby. It lists 4,518 scfh at half load and 8,370 scfh at full load on a supply pressure of 14 to 20 inches of water column, so the gas service has to be sized for that flow.

Both fuels are cataloged separately in industrial diesel generators and industrial natural gas generators.

Enclosure Levels and Footprints for 750 kW Sets

At 750 kW the enclosure choice sets the footprint, the lifting weight, and how much noise reaches the neighbors. Both Generac 750 kW sets come as an open set or in a weather-protected enclosure, in steel or aluminum, or in Level 1 or Level 2 sound-attenuated enclosures. The diesel SD750 adds a steel-only Level 3. The sheets list no dB(A) values, so ask for noise data on the exact enclosure.

• SD750 open set: 154.4 x 71.0 x 74.5 inches and 10,468 to 10,913 lb. The weather-protected steel enclosure adds 2,467 lb on a 207.4 x 71.0 x 80.0 inch footprint, and Level 1 is 247.5 inches long.
• SG750 open set: 178.3 x 82.6 x 110.3 inches and 14,824 to 16,967 lb. Weather-protected steel versions weigh 18,631 to 20,666 lb, and Level 2 versions run 340.0 x 151.4 x 153.0 inches.
• Delivery: Weights at this size call for a crane or heavy rigging and a pad rated for the set plus its tank, and Generac notes its dimensions are approximate and for estimation only.

Where a 750 kW Quote Changes: Sound Level, Base Tank, Pad Work

What goes into a 750 kW quote:

• Condition: Compare new generators with used generators: whether the set is new or used is one of the larger price variables at this size.
• Enclosure level: Open set, weather-protected, and Level 1, 2, or 3 sound enclosures, in steel or aluminum, change both cost and weight.
• Sub-base tank: The SD750 offers 334, 1,001, or 2,002 gallons, matching 6, 20, or 40 hours.
• Engine and fuel: The diesel set uses an 18.1 L Perkins engine and the gas set a 33.9 L V12, and fuel type moves price.
• Site work: Pad, rigging, and delivery distance add to the total.
