We follow industry best practices from initial design through commissioning, supported by logistics operations that keep equipment moving on schedule and ensure reliable delivery for complex data center environments.

Delivering Complete Data Center Power Solutions

A data center’s power architecture is only as strong as its weakest component. That is why we approach every project as an integrated system, supported by equipment sourcing, engineering, logistics, installation, and long-term service. Our solutions include:

  • Diesel and natural gas generators for emergency power
  • UPS systems for continuous power quality and ride through
  • Automatic transfer switches and switchgear
  • Power distribution systems, including PDUs and RPPs
  • Mobile UPS trailers for live upgrade work
  • Battery energy storage systems for hybrid and microgrid applications
  • Fuel tanks, enclosures, and all supporting infrastructure

With decades of industry experience, we help data centers secure reliable equipment quickly, even during periods of supply chain volatility. Our vendor-neutral sourcing model allows us to provide the right system for the application without limitations from single manufacturer product lines.

Reliable Generator Systems for Mission Critical Applications

Backup generators are the foundation of any resilient data center power system. We provide EPA Tier 2 and Tier 4 generator solutions engineered for rapid start, dependable load acceptance, and long-term reliability. Features include:

  • Generator packages from leading manufacturers
  • EPA Tier 4 certified systems for strict emissions regions
  • High-capacity fuel storage options
  • Custom and sound-attenuated enclosures
  • Control integration and paralleling capabilities

Every generator is configured around site-specific electrical requirements, environmental conditions, fuel strategy, and compliance obligations. Our engineering team supports load analysis, system modeling, paralleling design, and power studies to ensure performance during real outage conditions.

Advanced UPS Systems for Continuous Power Conditioning

Power quality and ride-through capability are essential for modern, high-density compute environments. Global Power Supply supplies a full range of UPS systems designed for data center applications, including:

  • Double conversion UPS systems
  • Modular and scalable UPS architectures
  • Lithium battery solutions for improved lifecycle value
  • VRLA and advanced battery technologies
  • High power systems up to multi-megawatt configurations

UPS systems are delivered with comprehensive design and integration support, ensuring proper system sizing, distribution planning, and alignment with redundancy strategies such as N, N+1, and 2N.

Rapid Deployment and In-Stock Availability

Data center construction timelines continue to accelerate. Procuring long lead equipment can be challenging, and delays in generators, UPS systems, or switchgear can create significant project risk.

Global Power Supply maintains strategically sourced inventories of generators, UPS systems, ATS units, switchgear, and related equipment. This enables faster deployment for projects that cannot wait for standard lead times. Many items are available for immediate shipment with optional pre-configuration services. Our in-stock inventory also benefits data centers performing expansions, refresh cycles, or equipment replacements where downtime windows are limited.

Power Solutions for Live Site Upgrades

Live data center environments cannot tolerate service interruptions during infrastructure upgrades. We support these projects with specialized solutions that maintain uptime while power systems are replaced or reconfigured. These solutions include:

A dedicated project team coordinates all logistics and technical steps, ensuring a controlled and predictable migration without risk to critical operations.

Custom Enclosures, Fuel Systems, and Site Infrastructure

Every data center site presents unique environmental and regulatory requirements. We design and supply custom generator enclosures, extreme weather packages, and fuel systems that meet both operational needs and local code requirements. This includes weatherproof and sound-attenuated custom enclosures, UL 142 and UL 2085 fuel tank systems, seismic-rated solutions, high altitude and cold climate generator configurations, as well as exhaust systems, ventilation, and environmental controls.

These engineered components ensure reliable performance in demanding site conditions and provide compliance with local building codes, sound ordinances, and emissions regulations.

Data Center Generator FAQs

When uptime is everything, having the right backup power plan in place is essential. Whether you’re upgrading an existing system or designing a new facility, Global Power Supply has the expertise and energy solutions to keep your data center operations running without interruption.

Below, we’ve answered some of the most common questions about data center backup power generators to help you make informed decisions about reliability, scalability, and compliance.

What are data center power solutions, and how do they ensure continuous uptime?

Data center power solutions include the integrated systems and infrastructure that deliver continuous, clean power to IT and facility equipment. These solutions typically combine uninterruptible power supply (UPS) systems, standby generators, automatic transfer switches (ATS), switchgear, and power distribution units (PDUs). Together, they provide redundant and conditioned power that protects against outages, surges, and voltage irregularities, ensuring your data center maintains uninterrupted uptime and operational resilience.

What types of backup and redundant power systems are used in data centers?

Modern data centers rely on multiple layers of backup and redundant power systems to maintain reliability. These include diesel or natural gas generators for long-duration standby power, UPS systems for instantaneous transfer during utility loss, battery energy storage systems (BESS) for load support, and ATS and switchgear for automatic source management. These components are configured in N, N+1, or 2N redundancy designs, depending on the data center’s required level of reliability and uptime classification.

How does Global Power Supply help design or integrate customized data center power systems?
