Generator Service for PGT25+ / PGT25+G4 Turbine
Do you run a PGT25+ / PGT25+G4 (Baker Hughes)? TEMISA Power Gen services the ELECTRICAL GENERATOR coupled to it — not the turbine. Independent ally of the OEM: overhaul, stator/rotor rewind, electrical testing and dynamic balancing.
Important: TEMISA does not repair the PGT25+ / PGT25+G4 turbine. We specialize in the electrical generator coupled to it — the OEM's ally on the electrical side.
The turbine
PGT25+ / PGT25+G4 — Baker Hughes
- Type: Aeroderivative gas turbine
- Power range: 31–38 MW
- Application: Mechanical-drive compression and oil & gas generation
- Coupled generator: High-speed synchronous generator (generation variant)
- In our market: PEMEX compression packages and gas infrastructure.
The challenge on the generator
Shares the LM2500+ core — the coupled generator needs the same insulation diagnostics and Class F/H rewind.

Questions we often receive. Can't find yours? Email us at ventas@temisapowergen.mx.
Does TEMISA service the PGT25+ / PGT25+G4 turbine itself?
No. TEMISA Power Gen specializes in the ELECTRICAL GENERATOR coupled to the PGT25+ / PGT25+G4 (Baker Hughes), not the turbine. We are an independent ally of the turbine OEM: we maintain, rewind, test and rehabilitate the function toLowerCase() { [native code] } — overhaul, stator/rotor rewind, electrical testing (RSO, ELCID, partial discharge) and dynamic balancing, under ISO 9001:2015.
What generator is coupled to a PGT25+ / PGT25+G4?
Typically a High-speed synchronous generator (generation variant). Shares the LM2500+ core — the coupled generator needs the same insulation diagnostics and Class F/H rewind.
Why an independent shop instead of the turbine OEM?
Because the turbine OEM rarely specializes in the generator. An independent multi-OEM shop responds according to availability with priority attention and remote assessment, avoids lock-in and protects continuity with fast, certified generator service — critical when every hour of unplanned downtime counts.
Do you serve Baker Hughes equipment across Mexico, Central America and offshore?
Yes. Independent multi-OEM service from our 5,600 m² workshop in Tlajomulco, Jalisco, with on-site field service. We review your equipment information and confirm what is needed to define the scope and quotation timeline.
