500 kW Generators for Production Lines, Manufacturing Plants, Large Facilities, and More

A 500 kW generator is a common choice for entire office buildings, medical equipment, telecommunications and data center operations, and for large manufacturing facilities running production processes. It also powers multiple motors, pumps and fans and serves as backup during blackouts.

500 kW as an Entry Point for Data Center Power

500 kW is often where data center operators start the sizing conversation, even though it’s on the smaller end of what larger facilities eventually need. Smaller colocation sites, edge data centers, and IT infrastructure supporting a single building typically fall in this range, while hyperscale facilities scale up from here into the multi-megawatt territory of paralleled units. What matters most for data center applications at this size is fast, automatic transfer — the switchover from utility to generator power needs to happen within seconds to avoid any interruption to server uptime.

Outage Performance and Load Assessment at 500 kW

A 500 kW set often backs a whole facility rather than one process, so the sizing question becomes which circuits transfer to the generator and which stay off. Draw that boundary on the one-line diagram, total the transferred loads, and test the result against the largest motor start. Our power calculator is a useful starting point for that total. Amps at 208V, 480V and other voltages are listed on our amperage chart.

LP Backup and Gas Rating Limits at 500 kW

At 500 kW, diesel units usually carry their fuel in a base tank, while natural gas units are tied to the site’s gas service. Diesel. Our diesel fuel consumption chart shows the 500 kW row at 11 gal/hr for 1/4 load, 18.5 gal/hr for 1/2 load, 26.4 gal/hr for 3/4 load, and 35.7 gal/hr for full load. That chart is for diesel only and does not apply to natural gas sets. For a specific model, check the manufacturer’s sheet. Caterpillar’s XQ500, for example, lists 35.9 gal/hr at 100% of its standby rating. Natural gas. Kohler’s 500REZXD makes 500 kW standby on natural gas with a 21.9 L D219L engine and is EPA-certified for stationary emergency use. Kohler lists 5888 cfh at full load and 3414 cfh at half load, and calls for 7.0 to 11.0 in. H2O of supply pressure measured at the generator fuel inlet. It is a dual-fuel model that can switch to LP vapor, but its LP standby rating drops to 295 kW, so loads should be planned around that lower figure if LP is the backup fuel. For wiring, the 500 kW row of our amperage chart lists 1735 amps at 208V and 752 amps at 480V. Our power calculators can help you check whether 500 kW covers your load. Natural gas units and diesel units are on separate pages, each unit labeled by fuel.

Road Width, Height, and Weight for Containerized 500 kW Sets

At 500 kW, a towable set is usually a container on a chassis, so check the size on the road as well as the electrical rating. Under FHWA standards, states may not set a width limit of more or less than 102 inches on the National Network, and there is no federal height limit; FHWA reports state height standards from 13.6 feet to 14.6 feet. Caterpillar’s XQ500 rental power module (500 kW standby, 455 kW prime, Tier 4 Interim) shows the numbers to check:

• Package: A 20′ ISO high cube container on a 2-axle, 20′ ISO container chassis, with an anti-lock brake system.
• Footprint on the chassis: 240 in long, 96 in wide, and 150 in tall. Off the chassis, the container is 102 in tall.
• Weight: 22,590 lb with oil and coolant and an empty tank, or 27,595 lb with full fuel. The chassis adds 7,450 lb.
• Fuel on board: A 700-gallon double-wall UL-listed tank, rated by Cat for 24 hours of runtime at 75% of prime +10%.
• Site impact: Rated at 72 dB(A) at 7 m, with 110% spill containment for engine fluids.

Your route, permits, and the height of the delivery vehicle still need to be checked for each move. For towable units, visit our trailer-mounted generators.

Container, Skid, or Switchgear Included? Pricing a 500 kW Unit

A 500 kW purchase can be a containerized rental module, a skid-mounted standby set, or a dual-fuel gas unit, and each is priced on different terms. Compare these items:

• Package type: A 20′ ISO container on its own chassis, like the Caterpillar XQ500, comes with its own fuel tank, silencer, and enclosure. A skid-mounted standby set may need those items bought separately.
• Emissions level: The XQ500 is Tier 4 Interim. The Kohler 500REZXD gas set is EPA-certified for stationary emergency use. Each certification limits where and how the unit can run.
• Fuel flexibility: Dual-fuel gas sets add automatic transfer between natural gas and LP. On the Kohler 500REZXD, LP output is 295 kW compared with 500 kW on natural gas.
• Transport: With full fuel and its chassis, the XQ500 is a heavy load. Delivery distance and permit requirements affect what you pay to get it on site.
• History of the unit: New industrial generators come without run time. For used industrial generators, compare hours and service records.
• Paralleling and switchgear: Breakers, controls, and load-sharing wiring for multiple units are separate costs.

Manufacturing and Processing Loads Backed by 500 kW

A 500 kW set carries the main circuits of manufacturing and processing lines through an outage, then returns them to utility power through its transfer equipment when service resumes.

Starting Point Questions for a 500 kW Buyer

• Single mid-size manufacturing facility or infrastructure project → our 400 kW generator may cover it for less
• Small data center, larger manufacturing operation, or citywide backup power → 500 kW is a common starting point
• Hyperscale data center or heavy industrial complex → look at our 600 kW generator and above, often deployed in parallel for large-scale redundancy
