Generator Service for Mining Operations
Maintenance, rewind, repair and commissioning of electrical generators in open-pit, underground and remote mining operations — gold, silver, copper and coal. 24/7 priority response under CFE LAPEM W4200-12, IEEE 115 and IEC 60034.

What mining operators are solving today
Mining runs 24/7 with minimal tolerance for downtime. Critical generators — both primary generation and backup — sit in a chain where a single failure stops the entire processing plant.
- 24/7 operation with near-zero tolerance for downtime — every hour of mill outage carries heavy production loss
- Dust, structural vibration and corrosive environments in processing plants
- Generators subject to continuous variable load from grinding mills, conveyors and crushers
- Remote substations and remote sites with complex logistics for mobilization and spares
- Emergency power for critical assets with strict SLAs (hoists, dewatering, ventilation)
- Electrical compliance under local mining regulation and ground-fault protection requirements
Why TEMISA Power Gen
Six differentiators for mining operations
CFE LAPEM W4200-12 certification — electrical generators 1 to 100 MVA
In-shop repair and rewind in our own facility — no overseas turnaround required
Specialists on 24/7 availability — not a call-center dispatch
Documented coverage across high-mining-activity states in northern Mexico
Recovery of generators that other shops discard, with HV testing after repair
ISO 9001:2015 traceability for operator audits and corporate compliance

FAQ
Frequently asked questions — Mining generator service
Preguntas que recibimos con frecuencia. ¿No encuentras la tuya? Escríbenos a ventas@temisa.mx.
Do you serve mining plants in northern Mexico and remote regions?
Yes. We have documented coverage across high-mining-activity states in northern Mexico, including remote and open-pit sites. Logistics and site-access permits are coordinated at contract start, operating under CFE LAPEM W4200-12.
Can you rewind large generators from a mining plant?
Yes. Our shop in Tlajomulco has capacity to rewind electrical generators up to 100 MVA under CFE LAPEM W4200-12. Certified copper, Class F/H insulation, VPI impregnation and post-repair HV testing. No overseas turnaround required.
How do you handle emergencies at a remote mine site?
Priority response coordinated with mine operations with pre-arranged logistics. For remote sites, access permits and work windows are validated at the start of the call. ISO 9001:2015 traceability is preserved through emergency interventions.
Do you maintain mine substations and ground-fault systems?
Yes. We service electrical generators in mine substations. The inspection scope includes thermography, vibration analysis, electrical testing and protection review aligned with applicable mining regulations and grounding standards.
Are you OEM-independent for mine generator brands?
Yes. We deliver independent multi-OEM service for generators present in mining operations: Toshiba, GE, Siemens, ABB, Brush, WEG and others. No OEM lock-in — any installed platform is supported.
