Capacity upgrades
Facility expansion, changing loads and infrastructure upgrades can leave a previous generator outside the new power plan, even if it was still operating when replaced.
Surplus industrial power equipment
Sell surplus industrial generators.
Move beyond idle equipment.
A replaced standby unit. A generator from a closed facility. Equipment purchased for a project that changed. We work with companies looking to sell industrial generators they no longer need.

How surplus happens
Your power requirements change.
Your equipment inventory should follow.
Generators are purchased for a specific need: backup power, remote operations, temporary projects or on-site generation. When that need changes, a substantial asset can remain on a pad, in a warehouse or in a yard without a clear next step.
Closures & consolidation
Plant shutdowns, site relocations and consolidation can release generators and associated equipment that are no longer required at the original location.
Projects & fleet changes
Cancelled installations, completed temporary work and adjustments to equipment fleets can create unused or underutilized generator inventory.
Before declaring a generator surplus, confirm with facilities and operations that it is no longer required for backup coverage, planned projects or internal redeployment.
Identify the asset
Industrial generators come in different configurations.
We welcome inquiries about complete generator sets and related power equipment. Fuel type, rated output, installation configuration and condition help establish what you have and whether further evaluation makes sense.
Diesel generator sets
Industrial diesel units in open, enclosed or containerized configurations. Include the engine model, generator set designation, fuel tank arrangement and operating hours.
Natural gas & propane units
Gas-fueled generator sets. Identify the specified fuel and configuration from the equipment documentation rather than assuming the unit can run on another fuel.
Standby generators
Units installed for backup power. Record the standby rating, exercise and service history, and any recent load testing. Low hours alone do not establish condition.
Prime & continuous-duty units
Equipment identified for prime or continuous operation. Provide the manufacturer’s stated duty rating and available maintenance records alongside the output rating.
Mobile & trailer-mounted sets
Generators used for temporary work or company fleet operations. Describe the trailer, enclosure, connection panels and included equipment, plus any ownership documents available.
Associated power equipment
Transfer switches, switchgear, paralleling controls and other components offered with the lot. List each item separately and identify what is included with the generator.
These categories can overlap: a diesel unit may also be mobile or standby-rated. Describe the actual configuration and use rather than relying on a single category.
Recognizable equipment. Specific details.
The brand starts the conversation.
The nameplate moves it forward.
Have a generator set from one of these manufacturers or product families? Include it in your inquiry. Other brands and legacy units are welcome too.
Caterpillar / Cat · Cummins · Kohler · Generac Industrial Power · mtu · FG Wilson · Atlas Copco · Multiquip
Brand names identify equipment only. Generators Outlet does not claim manufacturer authorization, endorsement or affiliation.
Identify the complete generator set.
An engine brand alone may not identify the assembled unit. Capture the generator set, engine and alternator nameplates, along with the controller details when available.
- Full model and serial numbers
- kW and kVA output, as marked
- Standby, prime or continuous rating
- Voltage, phase and frequency
- Fuel type and indicated operating hours
Keep the rating basis clear. Standby, prime and continuous outputs should not be treated as interchangeable, and kW and kVA describe different quantities.
Condition tells part of the story
Hours matter.
History adds the context.
A low-hour generator may have spent a long time idle. A higher-hour unit may have detailed service records. Neither situation can be assessed from the hour meter alone.
Share what is known: last operation, maintenance history, load-bank test reports, storage conditions, leaks, alarms, repairs and missing components. If the equipment has not been tested recently, describe its status clearly.
Existing photos, inspection reports and operating videos can help document condition. Any new testing or disconnection should be arranged through qualified personnel.
A practical path to the next step
Start the discussion before the removal deadline.
A generator is more than a line on an inventory sheet. Clear equipment information and an understanding of site access help make a proposed transaction easier to evaluate.
Gather the equipment details
Collect nameplates, overview photos and available records. Identify the generator, associated components and any items that will remain at the site.
Explain the scope
Describe condition, ownership, location and timing. Note whether the unit is connected, whether access is restricted and what you know about loading requirements.
Discuss a sale
Send an inquiry for review. Inventory fit, commercial terms, inspection requirements and responsibility for removal and transport need to be agreed for the specific asset.
Value and logistics belong together
Look beyond the original purchase price.
Potential resale value depends on specifications, condition, completeness, records and demand. Location, access and removal requirements also affect the practicality of a transaction.
A recognized brand, large output rating or low hour reading does not guarantee an offer. A clearly described asset gives the review a stronger starting point.
Make site conditions visible early.
- Indoor equipment room, rooftop, outdoor pad or storage yard
- Doorways, clearance and vehicle access
- Known lifting or loading constraints
- Electrical, fuel and exhaust connections still attached
- Included tanks, exhaust components and controls
- Site scheduling or contractor requirements
Keep components and documentation together while the sale scope is being discussed. Agree on disconnection, removal and handling responsibilities before work begins.
Common questions
Selling surplus industrial generators
Can I inquire about a generator that is still installed?
Yes. Include photos showing the installation and explain whether it remains connected or in service. Site access and the scope of disconnection and removal need to be reviewed before a transaction is finalized.
What if the generator has not run recently?
Describe it as untested or state when it last operated, if known. Share service records and storage history. Do not claim operational readiness based only on prior use or an hour meter reading.
Can I submit non-running or incomplete equipment?
Yes. Disclose faults, missing parts and any diagnosis already available. Whether there is a suitable opportunity depends on the specific unit, condition and logistics; acceptance is not guaranteed.
Do you consider unused generators from cancelled projects?
We welcome those inquiries. Include storage and commissioning status, documentation, included accessories and clear photos. Distinguish never-installed equipment from units that were installed but not put into regular service.
Should I include the transfer switch or switchgear?
Include any associated equipment you intend to sell, with its own identification and photos. Specify whether it is part of the generator lot or offered separately. Compatibility should be verified from the relevant documentation.
Is a purchase or price guaranteed?
No. Any offer depends on review of the equipment, condition, scope and logistics. Share the information you have to establish whether further evaluation is appropriate.
Put idle power equipment on the agenda
Have an industrial generator your company no longer needs?
A single standby unit or multiple generator sets — start with the details you have and let’s discuss the opportunity.
