Independent multi-OEM workshop
About our GE Vernova service
GE Vernova (formerly GE Power + Alstom) operates a large installed base of large turbogenerators across Mexican utility power plants — CFE thermal facilities, combined-cycle IPPs, and refinery cogeneration. Beyond OEM warranty + LTSA, independent multi-OEM workshops represent the operational alternative for cost-effective full-life-cycle asset management. TEMISA Power Gen services GE Vernova generators under the same international standards GE itself applies.
Workshop capabilities
What we deliver on GE Vernova
- Turbogenerator service within the 1–365 MVA field range, confirmed from the nameplate
- Stator rewinding with VPI Class F or H insulation under EASA AR100
- EX2100e + EX2000 brushless excitation diagnosis, field replacement, AVR tuning
- Cylindrical rotor inspection, dovetail repair, retaining-ring NDT and lifting
- Hot-section consultation for adjacent gas turbine sections (combustion + transition pieces)
- Dielectric package (Megger + IP + Tan Delta + DP + DC Hipot under IEEE 95)
- Vibration FFT under ISO 10816-2 + bearing analysis under API 670
- LTSA gap analysis — independent assessment vs OEM-bound contractual service
Applications
Industries we serve on GE Vernova
CFE combined-cycle thermal plants
Large 7HA / 9HA gas turbogenerators 200-450 MVA serving as base-load capacity in CFE-owned facilities requiring full IEEE 56 compliance for grid export.
Independent power producers (IPPs)
Combined-cycle plants with private LTSA expiration considering transition to multi-OEM independent service — full cost-benefit analysis available.
Refinery cogeneration
Process gas + steam turbogenerator trains in PEMEX refineries — steam turbine + generator overhaul during planned shutdown windows.
Industrial cogeneration
Medium-capacity GE generators 50-150 MVA in industrial cogeneration installations — sugar, paper, chemical, steel.
Frequently asked questions
How does TEMISA Power Gen service GE Vernova equipment?
TEMISA Power Gen is an independent multi-brand service shop; the manufacturer's name identifies the equipment serviced.
Should I keep my GE Vernova LTSA or transition to multi-OEM service?
Long Term Service Agreements (LTSA) with GE Vernova include availability guarantees and parts. For mission-critical IPPs without redundancy, LTSA provides operational security. For utility CFE base-load with redundancy and predictable operation, independent multi-OEM service typically costs significantly less than an LTSA, with equivalent technical compliance under EASA AR100 + ISO 9001:2015. The business case depends on asset criticality, redundancy and internal risk management capability.
Do you service GE EX2100e brushless excitation systems?
Yes. We perform full diagnosis of EX2100e brushless excitation: rotating diodes, brushless exciter, PMG (Permanent Magnet Generator), AVR digital boards, voltage transformer cabling and protection logic. Field replacement of components is standard service — typically completed in 3-5 days onsite. Major exciter rebuild requires workshop access with 2-3 week turnaround.
What's typical lead time for major GE turbogenerator overhaul in your workshop?
Lead time is set with the diagnosis and scope and given in the proposal. A major overhaul typically includes disassembly, inspection, rotor balance, stator inspection, electrical testing and reassembly; a field rewind extends it. We coordinate with onsite team for transport logistics + temporary plant operation arrangements.
