About our Mitsubishi service
Mitsubishi Heavy Industries Power Systems (MHPS, now Mitsubishi Power Ltd.) is a Japanese Tier-1 OEM with significant installed base in Mexican CFE thermal plants and private IPPs — both standalone synchronous generators and complete gas + steam turbine generation trains. As an independent multi-OEM workshop certified CFE LAPEM W4200-12, TEMISA Power Gen services Mitsubishi generators under IEC 60034 + IEEE 56 + EASA AR100 standards.

Applications
Industries we serve on Mitsubishi
CFE conventional thermal
Mitsubishi turbogenerators 200-700 MVA in CFE-owned thermal power plants — base-load operation with formal IEEE 56 overhaul cycles.
Combined-cycle IPPs (gas + steam)
Mitsubishi M501F / M701F gas turbine generators 200-450 MVA in private combined-cycle IPP plants serving CFE grid via PPA contracts.
Refinery + petrochemical cogeneration
Mitsubishi industrial generators 50-200 MVA in PEMEX refineries and petrochemical complex CHP installations.
Industrial cogeneration
Medium-capacity Mitsubishi generators driven by steam or gas turbines in industrial cogeneration — sugar, chemical, paper sectors.
Frequently asked questions
Are you an authorized Mitsubishi (MHPS / MHI) representative?
No. TEMISA Power Gen is an INDEPENDENT multi-OEM workshop — not a Mitsubishi authorized representative. Independent service workshops certified to CFE LAPEM W4200-12 and applying the EASA AR100 standard are fully compatible with Mitsubishi generators outside original OEM warranty (typically 2-5 years from commissioning).
What Mitsubishi generator lines do you service?
We service the Mitsubishi Power synchronous generator portfolio: industrial turbogenerators 100-700 MVA (cylindrical rotor + hydrogen cooling on larger units), industrial cogeneration generators 50-200 MVA, and standalone Mitsubishi generators driven by steam or gas turbines in CHP plants.
How does Mitsubishi service compare to OEM service in Mexico?
Mitsubishi Power Ltd. operates Mexican office for direct OEM service with parts inventory at limited regional depot. OEM service represents premium pricing with guaranteed parts. Independent multi-OEM service through TEMISA Power Gen represents 30-50% cost reduction with equivalent technical compliance under IEC 60034 + IEEE 56 + EASA AR100 standards — the same standards Mitsubishi itself applies in its factories.
What's typical overhaul timeline for Mitsubishi 500 MVA?
Typical timeline for 500 MVA Mitsubishi turbogenerator overhaul: 12-16 weeks workshop including disassembly, hydrogen system inspection, rotor balance, stator inspection, electrical testing, reassembly, commissioning. Add 4-6 weeks if stator rewind required. We coordinate hydrogen atmosphere handling under ASME pressure vessel codes + IEC 60079 electrical area classification.
