Why Data Centers Cannot Afford Power Gaps
Uptime SLA Commitments
Your customers expect 99.999% availability. A single unplanned outage can breach SLAs, trigger penalties, and erode trust built over years.
Data Integrity
Abrupt power loss risks corrupted databases, failed transactions, and lost writes. Clean backup power ensures graceful operations during grid failures.
Cooling Continuity
Servers generate enormous heat. Losing cooling for even minutes can trigger thermal shutdowns and hardware damage across entire racks.
Compliance & Audits
SOC 2, Uptime Institute certifications, and NFPA 110 all require documented, tested backup power. Non-compliance jeopardizes your certifications.
Built for Mission-Critical Uptime
Every component of your backup power system is designed, installed, and maintained to eliminate single points of failure.
N+1 Redundancy Design
We design systems with redundant generators so a single unit failure never takes your facility offline. True N+1 means no single point of failure.
Automatic Transfer Switches
Sub-10-second transfer to generator power with automatic retransfer when utility is restored. Coordinated with your UPS for zero-gap coverage.
Load Bank Testing
Regular full-load testing verifies your generators can handle real-world demand — not just idle at no load. We test to 100% of rated capacity.
Fuel Management
Fuel polishing, tank monitoring, and scheduled deliveries ensure your generators have clean, fresh fuel ready for extended runtime events.
Compliance & Certification Support
Uptime Institute Tiers
Tier II through Tier IV facilities require increasingly robust power redundancy. We design and maintain systems that meet your target tier certification.
NFPA 110
Emergency and standby power systems must be installed, tested, and maintained per NFPA 110. Our programs cover monthly testing and annual load bank verification.
SOC 2 Type II
Auditors verify that backup power is tested, documented, and reliable. Our detailed service reports provide the evidence your compliance team needs.
