Bridging the Power Gap During Data Center Commissioning

By Ben Inkrott

Globally, demand for data centers is increasing, fueling a boom in data center construction as a result. Building these facilities is a huge undertaking. With multimillion- or multibillion-dollar budgets and lengthy timelines, data centers are one of the biggest growth areas in construction. Credit ratings agency Moody’s projects there will be $3 trillion in global spending by 2030 to keep pace with rapid data center expansion and AI capacity demand. 

However, there is a potential bottleneck lurking on these large-scale builds: The power gap between initial facility construction and utility grid connection. Access to fuel is important during the construction phase for equipment, but it’s also crucial during data center commissioning, when mission-critical system and generator testing occurs. 

In this guide, we’re looking at how high-capacity fuel tanks help bridge the gap between construction and getting the facility online. 

What is data center commissioning?

Data center commissioning is a rigorous, quality-assurance process that is completed to help ensure a facility’s complex systems work as a unified whole. 

While construction focuses on building the shell and installing the equipment, commissioning verifies the building’s performance and resilience. During the various stages of the data center commissioning process, critical equipment and components, including power, security and building management systems, are tested for functionality and performance during both day-to-day and emergency situations. 

It’s one of the most critical stages of the data center construction process, as it confirms the reliability of power and building management systems in both day-to-day and emergency situations.

What Are the Fuel Demands During Commissioning?

During commissioning, temporary, large-scale diesel generators require massive volumes of fuel to run full-site power outage simulations before grid connection. 

So while data center construction requires substantial temporary fuel for heavy machinery, generators and site power, the commissioning process presents its own specific fuel challenges. 

In the final step of systems testing, using high-capacity fuel tanks is most critical. Because the entire facility is tested as one unit during this stage, it often includes a full-site power outage simulation to ensure that dozens of backup generators take the load instantly. And unlike excavators that can move to a fuel truck, these large generators are stationary and must run for extended periods during load testing. As a result, they require a substantial amount of fuel. 

If a generator fails during a commissioning test due to lack of fuel, it doesn’t just delay the day – it can set back the entire project schedule and lead to massive financial penalties.

How Do High-Capacity Fuel Tanks Solve the Power Gap?

High-capacity tanks solve the power gap by providing on-site bulk storage that creates a reliable buffer. This guarantees continuous extended run times and eliminates the chaos of daily fuel truck deliveries.

In environments where avoiding downtime is crucial, high-capacity tanks act as the vital bridge, ensuring that contractors can meet rigorous commissioning timelines. That means no more frequent service visits, which can interrupt progress and create risk when refueling.

Fuel storage tanks for data centers

For extended run times and protection against spills, leaks and associated environmental fines, Western Global offers a range of transportable and stationary external fuel tanks for diesel generators. They’re easily maneuvered into place and carry enough fuel to keep projects on track. 

Here are the fuel tanks we’d recommend for data centers:

• TransCube Global – our ultimate transportable fuel tank. Available in sizes up to 1,204 gallons, this tank unlocks the ability to fuel multiple pieces of equipment simultaneously. 
• TransTank Pro  –  delivers large-scale connectivity from an impressively small footprint. Available in sizes up to 18,000 gallons, these industrial fuel tanks are the ultimate solution for heavy-duty, on-demand applications.

It’s also important to right-size fuel storage for the operation. If you’re using 50 generators during commissioning, they should have a fleet of tanks to ensure each generator has a dedicated, reliable fuel supply.

What Technology and Logistics Should I Consider?

Choosing a fuel tank solution with real-time telematics and remote monitoring capabilities helps prevent human error by providing automated alerts when fuel levels are low across the entire site. This can help streamline the commissioning process rather than manually managing dozens of fuel tanks.

How Do I Power Data Center Commissioning? 

Bridging the grid gap isn’t just about having fuel; it requires a deployment strategy tailored to the operation. Having a unified plan allows for scheduled, efficient refills rather than emergency, high-cost short-fills. Working with fuel partners helps ensure the fuel bridge never runs dry while a data center is commissioned.
