What power generation operators are solving today
The power generation sector operates under simultaneous pressure from dispatch, fuel cost, CRE/CENACE regulation and the modernization of aged fleets. Every technical intervention has to close three equations at once: reliability, compliance and cost.
- Fleet modernization for units with 20 to 40 years of service under public utility operation
- Operational availability above 98% demanded by the grid for dispatchable assets
- Variable load curve that stresses synchronous generators, exciters and rotor windings
- Periodic technical audits required to keep generation permits valid
- Acceptance testing under IEEE 115 and IEC 60034 for commercial operation release

Commissioning of a synchronous generator at a private cogeneration plant
IEEE 115
Reference guide
Release or correct
Option evaluated
When a synchronous generator is commissioned at a private cogeneration plant, Hipot DC, polarization index, power factor and grid synchronization tests under IEEE 115 show whether the unit can be released. If a result does not meet the criterion, the cause is corrected and the affected tests are repeated.
FAQ
Frequently asked questions — Power generation service
Questions we often receive. Can't find yours? Email us at ventas@temisapowergen.mx.
Do you serve generators in CFE (Mexican utility) plants?
Yes. We service the generator and its excitation system. TEMISA's CFE LAPEM qualification 053/26 and its scope are published at /en/cfe-lapem-certified.
Can you commission new generators under IEEE 115?
Yes. We deliver the full acceptance package: Hipot AC/DC, polarization index, power factor, surge comparison, no-load and short-circuit saturation curves, and grid synchronization under IEEE 115. The signed acceptance protocol supports commercial operation release.
How is an emergency at a power generation plant handled?
Priority response coordinated with plant operations. The first phase is remote diagnosis to pre-stage critical spares and the right specialist profile before mobilizing. traceability is preserved even on emergency interventions.
Do you rehabilitate aged fleets of 20 to 40 years?
Yes. We rehabilitate generators in legacy fleets: upgrade of insulation systems to Class F/H, brushless exciter retrofit with digital AVR, protection modernization and major mechanical overhaul. Useful life is extended 15 to 25 years.
Do you handle cogeneration and self-supply IPPs under permits?
Yes. We serve private IPPs under CRE/CENACE permits: efficient cogeneration, self-supply and distributed generation. We deliver commissioning, scheduled maintenance and rehabilitation under the standards currently in force.
