Every PowerCore-Series unit ships from our 180,000 sq ft Pasadena assembly facility fully documented, fully witnessed via encrypted video, and backed by a 7-Year Uptime Guarantee that no competitor in our tier will put in writing. Browse the catalog below or specify directly with our applications engineers.
INCLUDED ON EVERY UNIT SHIPPED SINCE 2019 7-Year Uptime Guarantee · 99.97% availability · financial penalties per hour of deviation
Each family is built on the same control architecture, the same emissions platform, and the same factory acceptance testing protocol. The difference is duty cycle, installed footprint, and how the unit integrates with your site.
250 kW — 2.5 MW · Diesel & Gas
1 MW — 25 MW · Utility-Grade
250 kW — 12 MW · BESS-Integrated
The PowerCore-PP family covers the 250 kW to 2.5 MW load band across diesel and natural-gas prime movers. Configurable for 480 V to 13.8 kV service, every unit ships with a factory-mapped control board, on-board paralleling switchgear, and a witnessed live factory acceptance test before crate-out.
This matrix lists the standard feature set delivered on every PowerCore-Series shipment. Procurement and engineering teams use this table as the baseline specification against which alternate quotes can be benchmarked. Everything listed is contractual — not optional.

Hybrid is not a genset with a battery bolted on. The PowerCore-Hybrid controller is a proprietary dispatch optimizer — patented, in production since 2018, and continuously improved against field telemetry from every unit shipped. It sequences diesel run-time against battery state-of-charge, load forecast, fuel cost, and emissions targets in 1-second intervals.
Predicts the 30-minute load curve from 14-day rolling telemetry, ramp-rate constraints, and the operator's published dispatch schedule.
Pre-charges the BESS asset during low-load windows; absorbs peak transients with the battery; runs the diesel at its most efficient BSFC point.
Selects which gensets run, in what order, and at what load percentage to minimize fuel burned per kWh delivered — averaging 38% less than diesel-only across the deployed fleet.
Logs every dispatch decision; pushes a daily performance report to the operator; flags deviations from contract before they trigger an alarm.
Two 2 MW diesel gensets running in parallel can hold a 3 MW peak — but they burn fuel continuously, even at 30% load, and they rack up run-hours on the engines that shorten overhaul intervals. A single 2 MW diesel + 1.5 MW BESS holds the same peak, runs the engine at its sweet spot, and burns up to 38% less fuel per kWh delivered. The math is the same on a refinery island, a data hall, a copper mine, or a remote village.
A WesCorp applications engineer — all 84 hold active PE licenses in U.S. jurisdictions — will size the system against your load profile, fuel logistics, emissions jurisdiction, and interconnect requirements. You leave the call with a preliminary one-line diagram, a budgetary kW figure, and an honest read on whether a PowerCore-Series unit is right for your site.
