Industrial Power Systems / Engineering Proposal 04
Ruggedized Power Systems, Engineered From 250 kW to 25 MW.
WesCorp Energy designs, manufactures, and commissions diesel, gas, and hybrid power plants that keep refineries, mines, and data halls running when the grid cannot. Every unit ships pre-tested, pre-mapped, and contractually backed by a 7-Year Uptime Guarantee — written into every purchase order since 2019, with financial penalties per hour of deviation.

Engineered Power Platforms
Three product tiers. Distinct duty cycles. One engineering bench.
Every PowerCore-Series unit ships from our 180,000 sq ft Pasadena, TX assembly facility and is acceptance-tested before containerization. Pick the tier that matches your site's load profile — then scope a site assessment against it.
PowerCore-Prime
750 kW — 8 MW
Prime Power
Built for off-grid and weak-grid sites where utility power is unreliable or absent: mining, remote oilfields, and islanded industrial plants. Rated for unlimited running hours at variable load.
- Duty
- Variable, unlimited hours
- Fuel
- Diesel / Natural Gas / Dual-fuel
- Certification
- UL 2200 · EPA Tier 4 Final
- Buyer Fit
- Procurement leads at mining, O&G upstream
PowerCore-Continuous
1 MW — 25 MW
Continuous / Mission-Critical
Engaged for refineries, data halls, hospitals, and utility substations that cannot tolerate a transfer event. Sized for sustained load with paralleled units and N+1 redundancy architecture.
- Duty
- Continuous, baseload equivalent
- Fuel
- Natural Gas (preferred) / Diesel
- Redundancy
- N+1, N+2 paralleling architecture
- Buyer Fit
- Data centers, refineries, hospitals
PowerCore-Hybrid
250 kW — 12 MW
Hybrid Microgrid
Pairs a genset with battery storage and our proprietary load-sharing controller. Cuts diesel consumption 38% on average across 1,200+ deployed microgrids — without sacrificing ride-through.
- Duty
- Hybrid cycling, peak-shaving
- Controller
- Proprietary, patented load-share
- Diesel Reduction
- 38% avg. vs. genset-only baseline
- Buyer Fit
- Remote operations, cost-of-fuel sites

Request a Site Assessment →Eight Contractual Capabilities
Differentiators our competitors won't put in writing.
Each capability below is grounded in a measurable artifact — a contract clause, a patent filing, a CSA Group audit, or a published warranty term. These are the terms we negotiate with.
01
99.97% Contracted Availability
7-Year Uptime Guarantee on every PowerCore-Series genset shipped since 2019 — with financial penalties per hour of deviation. No competitor in our tier offers the same in writing.
02
84 PE-Licensed Engineers, Zero Subcontracting
Every power system is engineered in-house by PE-licensed electrical and mechanical staff. No third-party design work, no outsourced load calcs, no finger-pointing downstream.
03
38% Diesel Reduction, Proprietary Controller
Our patented load-sharing controller is field-proven across 1,200+ deployed microgrids — averaging a 38% drop in diesel consumption versus a genset-only baseline at equivalent load.
04
UL 2200 · EPA Tier 4 · ISO 8528-5
Full product line certified across UL 2200, EPA Tier 4 Final, and ISO 8528-5. Verification is recurring, not one-time — CSA Group audits the line every 90 days and issues a fresh attestation each cycle.
05
Factory Acceptance Testing, Witnessed Live
Every unit ≥ 1 MW undergoes full-load factory acceptance testing at Pasadena before shipment. Client engineers watch live via encrypted video feed — no surprises on the pad.
06
240+ Rental-to-Purchase Fleet
Largest rental-to-purchase conversion fleet on the Gulf Coast: 240+ units in active rotation. Average deployment-to-buyout cycle is 11 weeks — the shortest we have seen in this category.
07
14 Active USPTO Patents
Patent portfolio spans load-sharing controls and emissions-aftertreatment integration — IP that compounds with every shipped unit and is licensed only to our own engineers.
08
Zero Debt-Financed Projects Since 2014
Founded in 2008 by former Siemens Energy and Caterpillar-Marine engineers. We have financed 100% of our growth from operating cash — every project ships without a lender on the critical path.
Compliance Attestation
Regulatory baseline, not an upsell.
Every entry below is paired with a certification ID or award reference your procurement and legal teams can confirm against the issuing body. Recurring audits, documented cadence, no marketing-only badges.
UL 2200
Stationary Engine Generator Assemblies
Listed across the full PowerCore line. Verifiable in the UL Product iQ database under WesCorp Energy, Inc.

Industrial Applications
Six verticals. One engineering bench. No consumer-grade units on the floor.
Map the PowerCore catalog to your duty cycle. Each panel below names the industry, the typical power requirement pattern, and the configuration our application engineers most often spec for that load class.
01
Oil & Gas — Refineries and Midstream
5 – 25 MW · Continuous & Emergency
Refinery backup, pipeline pump stations, LNG liquefaction trains. Gas-fueled Continuous tier is the default spec; UL 2200 and NFPA 110 compliance are non-negotiable.
View refinery case parameters →02
Data Centers — Hyperscale & Edge
2 – 10 MW · N+1 / N+2
