Generac Holdings, Inc. has announced the release of a new range of high-capacity standby generators tailored to the evolving requirements of the data center industry. Unveiled on April 8, 2025, the launch underscores Generac's continued investment in scalable power solutions as the digital infrastructure sector experiences sustained growth.
The latest generator series includes five models ranging from 2.25 MW to 3.25 MW, developed to support diverse data center environments including hyperscale, enterprise, colocation, and edge facilities. These systems are powered by Baudouin M55 engines, equipped with high-pressure common rail fuel systems to optimize performance in high-load and high-temperature scenarios. The engines also meet stringent emissions standards, supporting compliance with regulations in states such as Virginia.
Integrated with each unit are Marathon DataMAX alternators, engineered to meet the unique power requirements of mission-critical applications. To eliminate single points of failure, each system incorporates redundant starting systems, featuring multiple batteries, chargers, and engine starters—crucial for ensuring uptime in facilities with zero tolerance for interruptions.
Generac’s new generator systems are designed to grow with demand, using Modular Power Systems (MPS) that easily connect multiple units without requiring extra switchgear. This built-in scalability and redundancy help data centers maintain power even during failures or surges in usage. High ambient cooling packages rated up to 50°C ensure reliable performance in extreme heat—an increasingly common concern in today’s climate.
To meet tight project timelines, Generac offers faster-than-average lead times of 50–60 weeks for complete, ready-to-install systems. These packages include enclosures, tanks, and switchboards, streamlining setup for operators. All models also support Tier 4 emissions technology to meet strict environmental standards.
As AI-driven computing and cloud infrastructure accelerate data center expansion, reliable backup power is no longer optional. Grid reliability issues, energy supply constraints, and severe weather events are prompting operators to reevaluate their emergency power strategies. The new product suite is designed to help organizations navigate these challenges through integrated, future-ready power systems.
