Power Requirement Analysis for 65 kW

Sizing a 65 kW generator starts with separating resistive loads such as heaters from inductive ones such as motors, because motors draw a starting surge well above their running figure. Add the growth you expect and note how long each load runs between rests. Temperature and altitude also lower an engine’s output, so a site with either may need the next size up. Our power calculator and a conversation with a generator specialist will confirm the match. Our amperage chart has no 65 kW row. Its 60 kW row (3 phase, 80% power factor) lists 208 A at 208V and 91 A at 480V, and its 75 kW row lists 261 A at 208V and 113 A at 480V. A 65 kW set draws somewhere between those two rows.

Refill Schedules and Gas Metering at 65 kW

At 65 kW, the fuel decision is mostly a question of refills: diesel has to be delivered and topped off on a schedule, while natural gas arrives through the meter as the engine draws it.

• Diesel tank sizes vary: Read the tank capacity on the spec sheet before you plan deliveries. Caterpillar’s DE65 GC lists a 27.2 US gal tank and, in 60 Hz service, burns 4.8 gal/hr at 100% load, 3.6 gal/hr at 75% and 2.5 gal/hr at 50%. Cat rates that model at 60 ekW (75 kVA) for 60 Hz standby; the 65 kVA figure applies at 50 Hz.
• Our chart: The diesel fuel consumption chart has no 65 kW row. Its 60 kW row reads 1.8, 2.9, 3.8 and 4.8 gal/hr at 1/4, 1/2, 3/4 and full load, and its 75 kW row reads 2.4, 3.4, 4.6 and 6.1 gal/hr. Those rows are estimates for diesel units and should not be used for natural gas units.
• Natural gas supply: Nothing to refill, but the gas service has to keep up with the engine. Generac’s SG070 (70 kW standby) sheet lists natural gas use of 928 scfh at 100% load and 475 scfh at 50%, with an operating fuel pressure of 5 to 14 inches of water column on natural gas.

Stock is sorted by fuel, with diesel units in one place and natural gas units in another.

Fuel and DEF Capacity on a Trailer at 65 kW

A trailer package can hold far more fuel than a standby set with a small base tank, and that decides how often someone has to drive out with a refill. Doosan Portable Power’s G70WDO-3A-T4F is one example; Doosan rates it at 56 kW (70 kVA) prime at 480V, so confirm that figure against your load first.

• Fuel on board: 110 gal usable, with a printed runtime of 25 hours at 100% load.
• DEF: a 5.1 gal tank for the SCR aftertreatment on its Tier 4 Final Doosan D34 engine, so diesel exhaust fluid belongs on the refill list too.
• Size on the road: 163.8 in long, 71.3 in wide and 93.3 in high with running gear, and 5550 lb ready to run.
• Running gear: Doosan lists torsion-style axles with a choice of electric or hydraulic surge brakes and an adjustable-height hitch across its G20 to G70 models.

Towable options at this size are on the trailer-mounted generators page.

Pricing Tanks and Fuel Systems on 65 kW Units

The cost of a 65 kW unit follows from these differences.

• Tank and fuel system: A 27.2 gal integral base tank, as on the Cat DE65 GC, and a 110 gal trailer tank with a separate DEF tank, as on the Doosan G70, are different builds with different costs.
• Condition: Compare new generators against used generators; on a used unit, service records and run hours shape its value.
• Output and voltage: Breakers and cable are sized to the current at your voltage, which is why a 208V installation costs differently from a 480V one. Use our amperage chart and power calculators to set those numbers.
• Emissions equipment: Tier 4 Final mobile units carry aftertreatment such as the DOC and SCR system on the Doosan G70.
• Mounting and transport: Trailer, skid or enclosed base, plus the haul out to you, are part of the bill.

How Long Will a 65 kW Generator Run?

Runtime depends on the fuel burn at your load and the size of the tank. Our diesel fuel consumption chart has no 65 kW row; its 60 kW row lists 1.8, 2.9, 3.8, and 4.8 gal/hr at 1/4, 1/2, 3/4, and full load, and its 75 kW row lists 2.4, 3.4, 4.6, and 6.1 gal/hr. Divide your tank size by the burn rate at your load to estimate hours of runtime. In industrial operations, the 65 kW generator provides a dependable power supply for machinery, equipment, and essential systems. With its capacity to provide continuous power, the 65 kW generator can help reduce downtime and support productivity during outages or remote operations. Each generator is built with durable fuel tanks and designed to accommodate various fuel types, ensuring dependable operation in a wide range of conditions. Depending on the product and model, 65 kW generators may come in different configurations, each offering specific features and dimensions tailored to industrial demands. Equipped with advanced controls and a reliable alternator, this generator type offers a dependable solution across many industrial applications.

Mixed Industrial Loads: Staying at 65 kW or Moving Up

A 65 kW set suits mixed industrial and commercial loads without being right for every job. Lighter loads, such as a single major piece of equipment or short runtimes, fit our 60 kW generator, while heavier continuous loads, several production lines or planned expansion fit our 70 kW generator, which adds headroom without a major jump in price.

Repair Support Once a 65 kW Set Is in the Field

Turnkey Industries has supplied quality generators for 10 years. A technician inspects and certifies each 65 kW unit before sale, and the 30-day IronClad warranty stands behind it. The service and maintenance team can be called on once the unit is installed. Look over the inventory or contact us with questions.
