GENERATORS BY INDUSTRY
Generators for Oil & Gas: What the Fields Run and What We Buy
In oil and gas, the generator often IS the power — remote sites with no grid run on diesel 24/7. That prime-power duty creates a distinct used market with its own rules.
Prime power, not standby.
The key distinction: prime power means running as the main source for unlimited hours; standby means waiting for the grid to fail. Oilfield units are prime-rated — typically 500 to 2,500 kW, skid-mounted for transport between sites, and paralleled so multiple units share the load and any one can be serviced without dropping the field.
A 725 kW-class oilfield unit is a workhorse size — big enough to matter, mobile enough to move with the operation.
Why skid-mounted and paralleled.
Oilfield equipment moves. Skid mounting lets a generator travel with the rig or production package, and paralleling lets operators add or remove capacity as the site’s load changes. It is modular power by design — which also makes these units straightforward to resell as complete running packages.
When oil & gas sells its used generators.
Site decommissioning, rig moves that strand power packages, and fleet standardization programs all release units. Prime-power hours run higher than standby duty — so hour meters and maintenance records matter more here than anywhere else. Well-documented oilfield units with mid-life hours are the sweet spot of this market.

FREQUENTLY ASKED QUESTIONS
Questions, answered.
What is prime power vs standby power?
Prime power is the main source — rated for unlimited hours, which is how remote oilfield sites run. Standby is backup for grid failure. The duty rating determines the unit’s design life and value.
What size generators do oilfields use?
Typically 500–2,500 kW prime-rated units, skid-mounted and paralleled — modular power that moves with the operation.
Why are oilfield generators skid-mounted?
Mobility: the power package travels with the rig or production site, and paralleling lets operators scale capacity up or down as loads change.
When does oil & gas sell used generators?
On site decommissioning, rig moves, and fleet standardization. Hour meters and maintenance records matter most in this prime-duty market.
Does Ironcrest buy used oilfield generators?
Yes — prime-power units included. Send the nameplate, hour meter, and photos; we buy single units and fleets nationwide.
INDUSTRY POWER
No grid. No problem. Just diesel.
Oilfield power is a different world from standby backup: these generators run as the primary power source, around the clock, in remote locations. Sizing, packaging, and duty ratings all follow from that reality.
