2007 CAT 3516C-HD 2500kW Diesel Generator Set

This 2007 Caterpillar 3516C-HD diesel generator set is a large-frame, ultra-high-capacity power system designed for utility, data center, energy, and heavy industrial standby and prime power applications. The unit is rated 2,500 kW standby and 2,250 kW prime at 60 Hz, operating at 1,800 RPM, and produces 277/480V, three-phase power. With only 690 original operating hours, this generator represents an exceptional opportunity to acquire a low-hour Caterpillar megawatt-class package.

The generator is powered by the legendary CAT 3516C-HD diesel engine, a heavy-duty platform engineered for high continuous loads and prime power duty. Controls are provided through a Caterpillar EMCP 3.3 digital control panel, offering full system monitoring, diagnostics, and protective shutdowns. Electrical output is delivered through two factory main breakers (one 4000-amp and one 3200-amp), allowing flexible high-capacity power distribution.

This unit is housed in a weatherproof enclosure and mounted on a massive 5,000-gallon sub-base diesel fuel tank, supporting extended runtime for critical installations. The package includes electric start, engine-driven radiator, standard air cleaners, 24-volt battery system with charging alternator, and a 120-volt battery charger. Built during Caterpillar’s heavy industrial era, this 3516C-HD platform is well-suited for data centers, utilities, mining, large manufacturing facilities, and prime power applications requiring dependable multi-megawatt output.
