Generator Service for Tier III and Tier IV Data Centers
Tier III and Tier IV data centers operate under availability SLAs above 99.982% and require N+1 or 2N redundancy in standby power. TEMISA Power Gen serves emergency diesel gensets and cogeneration plants in Mexico, Central America and the United States under NFPA 110, IEEE 446 and CFE LAPEM W4200-12. 24/7 service for critical assets where a single second of doubt in transfer costs contractual uptime.

What data center operators are solving today
A Tier III or Tier IV data center cannot afford a single second of doubt during load transfer to the standby generator. Every maintenance protocol has to satisfy Uptime Institute, NFPA 110 and the technical audits that the end client (hyperscaler, bank, fintech) imposes on its colocation provider.
- Availability above 99.982% (Tier III) or 99.995% (Tier IV) — annual downtime measured in minutes
- NFPA 110 Type 10 / Class X / Level 1 monthly testing without interrupting operation
- Redundancy N+1 (Tier III) or 2N (Tier IV) in standby generation
- Sub-10 second automatic transfer (ATS) with closed-loop synchronization
- Quarterly load bank tests at 100% resistive nameplate load
- Uptime Institute audits for periodic certification and recertification
- Coordination with colocation M&E for ultra-short service windows

FAQ
Frequently asked questions — Data center generator service
Preguntas que recibimos con frecuencia. ¿No encuentras la tuya? Escríbenos a ventas@temisa.mx.
Do you comply with NFPA 110 for Tier III and Tier IV data centers?
Yes. We execute maintenance programs under NFPA 110 (Standard for Emergency and Standby Power Systems) Type 10 / Class X / Level 1 — the standard Uptime Institute recognizes for Tier III and Tier IV certification. Monthly testing under real load or load bank, complete annual inspection and documented report for audits.
Do you perform load bank tests for data centers?
Yes. Quarterly or semi-annual load bank tests with resistive load at 100% of generator nameplate. This is the way to validate that the genset can deliver full load without overheating, voltage oscillation or mechanical failure. We deliver an IEEE 115 acceptance protocol and a graphical report with temperature, vibration and waveform data.
Do you work with N+1 and 2N redundancy schemes?
Yes. We coordinate scheduled maintenance in N+1 (Tier III) and 2N (Tier IV) arrangements without taking the data center's standby capacity out of service. Service windows are planned to respect the colocation's contractual SLA with the end client.
Do you support all diesel genset OEMs?
Yes. We operate as an independent multi-OEM workshop: Cummins, Caterpillar, MTU, Wärtsilä, Cat C175/C280, Stamford, Leroy-Somer and TD Power Systems. No OEM lock-in — any installed platform in the data center is supported.
Can you coordinate with Uptime Institute audits?
Yes. For data centers under Tier III/IV certification or recertification we provide technical documentation (test protocols, maintenance logs, calibration certificates) in a format compatible with Uptime Institute audits, M&O Stamp and Tier Certification of Constructed Facility processes.
