The challenge
Unstable loads and growing demand put a liquid rack cooling system under pressure
Unstable loads and growing demand put a liquid rack cooling system under pressure
Efficiency and reliability delivered through a hybrid energy solution
Lower fuel use. Greater reliability. Full visibility
A hyperscaler’s pump house powers its liquid cooling system—essential for maintaining optimal server performance.
But the existing power setup was not designed to handle fluctuating loads. As demand shifted, generators operated inefficiently, leading to frequent wet stacking and reduced reliability.
Load variability also drove inconsistent fuel consumption, resulting in frequent, costly deliveries—often with added fees for low-volume drops.
With AI-driven demand accelerating, the electrical contractor needed a more resilient and efficient solution. One that could stabilize performance, reduce fuel waste, and be deployed within two weeks—without disrupting critical operations.
We deployed a hybrid energy solution across two sites, centered on 1 MW battery energy storage systems (BESS).
Using real-time data from Aggreko Remote Monitoring, our engineers accurately assessed the pump house’s load profile and designed a system optimized for performance, efficiency, and reliability.
The solution combined:
Through the Aggreko Connect platform, the customer gained full visibility into asset performance, fuel usage, and emissions reporting—all in one place.
At Site One, we installed 1.2 MW of low-emissions generation. The dual-engine configuration operates independently within a single containerized unit, delivering built-in redundancy without increasing footprint.
At Site Two, two 600 kW generators were deployed, including a dedicated backup unit designed to isolate and respond instantly in the event of a system disruption—ensuring continuous cooling for critical infrastructure.
Both systems were installed, tested, and fully commissioned in under two weeks. This included detailed engineering validation, site walkthroughs, and safety-controlled installation areas to ensure a smooth and secure deployment.
The hybrid solution transformed performance at the pump house:
With stable power delivery during load fluctuations, the system protected critical equipment and avoided downtime risks.
The result: a more efficient, reliable operation—ready to scale with growing AI demand.
