Backup power starts with a reliable fuel supply.

As data centers continue to expand, so does the need for dependable petroleum fuel systems to support emergency backup generators.

This article takes an interesting look at how data center growth is impacting diesel fuel demand.

At PEI, we design, install and maintain petroleum backup fuel systems for mission-critical facilities where reliability matters.

Hospitals rely on a lot of behind-the-scenes systems to keep things running safely and efficiently.

This article is a great example of how looking at the bigger picture can uncover hidden issues, reduce waste and improve long-term reliability.

That same kind of planning is important for backup power. PEI provides fuel systems that support hospital generators and boiler systems, helping critical equipment continue operating during outages and emergencies.

Because in healthcare, being prepared isn’t optional.

Unpredictable weather is a good reminder that backup power needs more than a generator—it needs a dependable fuel system behind it.

Petroleum Equipment Inc. installs underground storage tank systems throughout Wisconsin and Illinois, helping facilities keep fuel available when outages or severe weather disrupt normal operations.

From planning and excavation to piping, electrical work and final installation, PEI can coordinate the full project from start to finish.

Because when the power goes out, your backup fuel system needs to be ready.

There’s no better compliment than hearing that PEI is a customer’s only call for their fueling systems.

"Petroleum Equipment, Inc. (PEI) has been a trusted partner with Waukegan Corporate Aviation Facilities (WCAF) for over 14 years. They installed our fuel system which had its challenges due to the unique layout of our facility. With 90 percent of the piping underground, they aligned the piping to run efficiently and effectively for our customers. PEI’s team knows our system so well, they can diagnose most concerns over the phone.

WCAF continues to utilize PEI’s knowledge to complete annual inspections and tank cleanings. Their turnkey operations get the job done right the first time, quickly and professionally. PEI isn’t just our first call, they are our only call when it comes to WCAF’s fueling systems."

—John S, Director of Maintenance at WCAF

Thank you to John and the entire WCAF team for trusting PEI for more than 14 years!

Big events rely on more than what happens on the field.

FIFA’s stadium guidelines highlight how critical resilient power systems, redundancy, and backup generation are to keeping stadium operations running — from lighting and broadcast needs to safety and essential communications.

At Petroleum Equipment Inc., we understand the importance of reliable fuel systems that support backup power when operations can’t afford to go down.

Whether it’s a stadium, data center, healthcare facility, or manufacturing plant, dependable infrastructure matters.

The devastating tornadoes in Illinois are a sobering reminder of how quickly severe weather can impact communities, businesses, and critical infrastructure.

While no system is immune to extreme weather, underground petroleum storage systems can help reduce exposure to wind-related damage and provide added protection compared to above-ground infrastructure.

At Petroleum Equipment Inc., we design and install underground petroleum systems that help businesses build for long-term reliability, safety, and resilience.

Our thoughts are with everyone affected by these storms.
