Cat G3520K Natural Gas Generator Set — 2,541–2,552 ekW, 97.6L V20
New Caterpillar G3520K natural-gas generator set for sale — a 2.5 MW-class continuous-rated V20 with up to 46.3% electrical efficiency, built for prime and grid-parallel power.
New Caterpillar G3520K natural-gas generator set available through Pantheon. Its 97.6-litre turbocharged and aftercooled V20 is rated 2,552 ekW continuous at 60 Hz (2,536 ekW with engine-driven pumps) and 2,541 ekW at 50 Hz, at 44.9–46.3% electrical efficiency depending on package. Cat offers it in High Response and High Efficiency packages, each at 0.5 or 1.0 g/bhp-hr engine-out NOx (250 or 500 mg/Nm³), with SCR aftertreatment for tighter limits. The engine turns 1,500 rpm; at 60 Hz the generator is driven through a speed-increasing gearbox. Generator voltages run from 480 V to 13.8 kV, and the set carries UL 2200 and CSA listings and ISO 8528-5 G1/G2 transient capability. It is the newest member of the G3520 line, alongside the G3520H (about 2.5 MW at 45%) and the G3520 Fast Response for standby duty. Exact rating, package, and configuration confirmed at quote.
