Custom Built 500-2000 kW Power Module Generators from WPP

If your business is in the market for a cost-effective and reliable mobile diesel generator (power module), you’ve likely found that expensive 500kW and smaller EPA Tier 4 Final generators are the only options on the market and delivery lead times are nearly a year.  At Worldwide Power Products, we’re pleased to say that’s no longer the case…

Our inventory now includes WPP-crafted, 500kW to 2000kW Power Modules in new, custom 20-40 foot high-cube containers with both low hour and refurbished Caterpillar generator sets. We have successfully completed and shipped dozens of custom power modules, with more in production and due to be completed in 2023 and beyond.

Proven Design

The design of our WPP500 Power Modules is based on the popular CAT XQ500 unit.

Many of the same elements users have come to appreciate with that unit–the UL1446 Recognized Class H Insulation, the distribution panel with customer convenience panel and multiple output receptacles–are included here, while some have been improved upon, such as the fuel tank size (700 gallon to 805 gallon) and the prime power runtime at 75% load (24 hours to 31 hours).
