Backed by Support You Can Count On
XQ2000 power modules are warrantied by WPP and backed by the same caliber of industry-leading support we provide for all our products.
We also offer fleet assessments to evaluate your existing inventory of power modules or generators, as well as refurbishment services such as engine overhauls and electrical system upgrades, to help you get the most life out of your current assets.
WPP works with CAT dealers to refurbish, recondition, or trade in existing power modules.

Common Questions About the XQ2000
How can refurbished power modules extend the life of my CAT rental fleet?
Refurbished modules allow dealers to keep high-hour units earning revenue instead of sidelined in the yard. WPP rebuilds and packages modules with new or reconditioned components, so you get reliable performance without the expense of Tier 4 Final systems. For dealers, that means stronger utilization rates, fewer gaps in the rental fleet, and more time before major capital outlay is required.
What’s the difference between Tier 4 Final and non-Tier 4 Final power modules?
The introduction of Tier 4 Final emissions standards changed everything in the mobile power market. These systems add complexity, higher upfront cost, and more expensive maintenance. Non-Tier 4 Final refurbished modules provide a cost-effective alternative—especially for low-load rental applications—without the downtime and headaches that often come with aftertreatment systems.
How quickly can I get a power module delivered?
Most packagers require 9–12 months or more to deliver a new module. WPP’s inventory is in stock and ready to move—typically under 4 months. That means you can respond to seasonal demand spikes, fleet gaps, or customer emergencies faster.
What sizes and kW ratings are available for your power modules?
We offer modules from 500–2000 kW, packaged in 20–40 ft ISO containers. Whether you need a 500 kW unit for pipeline projects or a 2 MW module for peak-shaving and utility support, we can size your solution to match your rental strategy.
Do your power modules integrate with CAT paralleling and control systems?
Yes. WPP’s modules are designed with utility and island mode paralleling, smart buss distribution, and advanced controls. They integrate seamlessly into mixed fleets, including CAT dealer fleets, so you can deploy them without extra infrastructure or control headaches.
What design features reduce downtime and make these modules rental-ready?
Our modules are built for ease of use in the field:
- Smart Buss Distribution with multiple connection options (camlocks, lugs, bare cable)
- Over-the-radiator exhaust (no roof penetrations or rain caps required)
- Built-in fuel pump system for easy external fuel supply
- Service-friendly layouts that simplify maintenance and shorten turnaround times
How do WPP’s power modules lower total cost of ownership for dealers?
- Lower upfront investment compared to Tier 4 Final units
- Reduced maintenance complexity and downtime
- Faster deployment = more billable hours
- Extended useful life of rental fleets without major capex
Are your refurbished CAT power modules EPA compliant?
Yes. All refurbished units meet EPA compliance standards for their class. WPP ensures emissions compliance while still delivering the performance and simplicity rental fleets demand.
Can I trade in or refurbish my existing CAT modules with WPP?
Yes. WPP works with CAT dealers to refurbish, recondition, or trade in existing modules. We help you maximize ROI on aging assets and keep your rental fleet competitive.
How do power modules fit into my rental fleet strategy during peak demand seasons?
Rental demand often spikes during hurricane season, utility outages, or industrial shutdowns. Having ready-to-deploy refurbished modules gives you faster response, higher utilization, and better margins without tying up capital in brand-new Tier 4 units that may sit idle.
