Data Center Generators and Battery Backup

Power generation interruptions can be catastrophic for data centers because downtime means lost data, lost revenue, and compromised customer trust. Data center backup power generators keep servers and network equipment running during power grid failures, ensuring your operation continues without disruption.

A battery backup is often part of a UPS (Uninterruptible Power Supply) system. These battery backups provide power instantly but only for a few minutes.

A data center generator, on the other hand, supplies long-term backup power using diesel or natural gas. The UPS bridges the gap until the generator starts, typically within seconds, and then the generator provides stable power for as long as needed.

A more reliable power supply alternative to battery backups is battery energy storage systems (BESS).

Yes. In fact, it’s standard to have both because the generator and a UPS can work together to provide uninterrupted power.

The UPS delivers instant power at the start of an outage, while the data center generator kicks in moments later and provides power until the utility grid is restored.

This combination ensures seamless and continuous power supply with no downtime or data loss.

Global Power Supply’s data center backup power solutions are engineered for seamless, automatic response the moment utility power fails. Our systems combine an uninterruptible power supply (UPS) with a standby generator that starts within seconds.

An automatic transfer switch (ATS) transitions the load to generator power without manual intervention. Every component is selected and configured to work in sync, ensuring your critical operations continue without interruption, data loss, or downtime.

With this setup, Global Power Supply ensures smooth, uninterrupted power throughout any outage. From design to integration, we build for reliability, speed, and total peace of mind.

Sizing depends on your total critical load, including servers, cooling, lighting, and more. We recommend adding headroom for future expansion.

Our engineering team will evaluate your load and design a solution that is right-sized for you and your needs. This helps you make sure that your data center generator can reliably handle real-world demands.

Absolutely.

Whether you operate a small server room or a large enterprise facility, our systems are built to scale. We design modular solutions with parallel-ready data center backup power generators, allowing you to expand capacity as your operations grow.

Yes. We engineer backup power systems to meet Uptime Institute Tier requirements, including N+1 and 2N redundancy models.

Whether you’re working toward Tier 1 or Tier 4 certification, we’ll configure a compliant solution that meets your data center’s resilience goals.

We offer both diesel and natural gas data center generators.

Diesel is preferred for its high output and reliability in emergencies. Natural gas offers cleaner operation and a continuous fuel supply via pipeline.

We’ll help you choose the best option for your facility based on local infrastructure and mission-critical needs.

Yes. Global Power Supply provides turnkey service — from site surveys and permitting to delivery, rigging, and commissioning.

We handle the full integration of data center backup power generators, UPS systems, ATS units, BESS, and load banks to guarantee a seamless power infrastructure.

We offer EPA-compliant generators, including Tier 4 Final models, and support clients with emissions permitting and compliance paperwork.

Our expertise in all things generators can give you the peace of mind that your backup power system meets environmental standards across states, including California and other regulated areas.

Monthly testing is recommended to verify operational readiness. Full maintenance — including oil changes, coolant checks, and fuel testing — should be performed at least twice a year.

Annual load bank testing ensures your data center generator can handle its full rated capacity under real-world emergency conditions.

Yes. Our generators can be equipped with remote monitoring systems that track performance metrics like load, temperature, fuel levels, and fault codes.

This provides real-time visibility, alerts for potential issues, and peace of mind for your operations team.

As long as it has fuel. Diesel generators can operate for hours or even days with a properly sized fuel tank. Natural gas generators can run continuously if connected to a reliable gas line.

We’ll work with you to design a solution that matches your required runtime.
