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, TEMISA Power Gen services Mitsubishi generators under IEC 60034 and the EASA AR100 standard, with IEEE 56 as reference guide.

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
How does TEMISA Power Gen service Mitsubishi (MHPS / MHI) equipment?
TEMISA Power Gen is an independent multi-brand service shop; the manufacturer's name identifies the equipment serviced.
What Mitsubishi generator lines do you service?
We service the Mitsubishi Power synchronous generator portfolio: industrial turbogenerators (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?
Compare the independent service proposal with the manufacturer proposal using the same scope, parts specification, acceptance tests, schedule and written warranty. TEMISA Power Gen provides independent multi-OEM service; price, delivery and compatibility are confirmed for the specific machine. Applying an industry standard does not grant OEM authorization.
What's the typical overhaul timeline for a large Mitsubishi turbogenerator?
Lead time is set with the diagnosis and scope and given in the proposal. A major overhaul typically includes disassembly, hydrogen system inspection, rotor balance, stator inspection, electrical testing, reassembly and commissioning; a stator rewind extends it. We coordinate hydrogen atmosphere handling under ASME pressure vessel codes + IEC 60079 electrical area classification.
