How Much Is a Used Data Center Generator Worth?

A used data center standby generator is typically worth between $8,000 and $250,000+ depending on kW rating, brand, runtime hours, fuel type, and whether an enclosure and transfer switch are included. Low-hour diesel units from Caterpillar, Cummins, and Kohler hold the most value. Data Center Buyers pays top dollar and quotes within 24 hours.

Standby generators are among the highest-value assets in any data center decommission. This guide explains what determines a used generator's resale value and how to maximize your return.

What determines a used generator's value?

Power output (kW/kVA) is the primary driver, followed by runtime hours — low-hour units command a strong premium because they have most of their service life remaining.

Brand and fuel type matter too: diesel units from Caterpillar, Cummins, Kohler, Generac Industrial, and MTU are the most liquid. A weatherproof enclosure, sub-base fuel tank, and matching automatic transfer switch all add value.

Typical used generator value ranges

Smaller units (100–500 kW) commonly range from roughly $8,000 to $60,000, while large units (750 kW to 3 MW+) can reach well into six figures, especially low-hour, late-model diesel sets with full accessories.

These are indicative ranges; your firm offer depends on the specific model, hours, and configuration.

How to sell your generator for the most

Document the model, serial, kW rating, hours, fuel type, and accessories, and include nameplate and installation photos. Recent load-bank or maintenance records help buyers price confidently.
