In data centers, downtime is measured in seconds — and the systems behind backup power carry real weight.

When utility power goes down, a data center's backup systems have almost no room for hesitation. Every second of delay adds up fast.

That's why the equipment supporting that transition — generator enclosures, switchboards, and everything connecting them — matters as much as the generator itself. It's engineered to help keep critical operations running when the grid can't.

Reliability isn't a single component. It's the whole system working together.

Heat, rain, snow — enclosures are engineered with the elements in mind.

Our customers pick their climate — and our generator enclosures have to work in it. Whether it's sitting through a heat wave, rain, or a heavy snowfall, it needs to keep protecting the equipment inside.

That's why weather resistance is built into the design from the start — corrosion-resistant coatings, sealed access points, and materials chosen to hold up over years of outdoor exposure, not just a season.

Built for the environment it's actually going into, not just the one on paper.

Behind every backup power system is a switchboard built to keep pace with it.

Generators get most of the attention in a backup power system — but the switchboard is doing just as much work. It's the piece that takes generator output and routes it where it needs to go, safely and in the right amounts.

Our subsidiaries Technibus and Plant Power & Control Systems specialize in low-voltage switchboards that are UL 891 listed and built to handle systems up to 6,000 Amperes. Each one is engineered around the specific load and layout requirements of your project rather than a one-size-fits-all design.

When the power's on the line, the switchboard is where reliability gets put to the test.

From raw steel to ready-to-ship: a look inside how an enclosure comes together.

Ever wonder what it takes to turn raw steel into a finished generator enclosure?

It starts long before the first weld — with engineering drawings, material selection, and a plan for every cut. From there, our fabrication teams move through cutting, forming, welding, and finishing, with quality checks built into each stage.

It's precision work, done across a manufacturing footprint that spans millions of square feet nationwide. Follow along as we take you inside the process!

Protecting the infrastructure that powers the digital world.

Behind every data center, healthcare facility, manufacturing plant, and critical operation is infrastructure that must perform when it's needed most.

IES Infrastructure is proud to help support those systems through custom generator enclosures, low-voltage switchboards, engineered fabrication, and mission-critical power solutions.

With 3.1 million square feet of manufacturing space, more than 2,000 generator enclosures produced annually, and a commitment to engineering excellence, we're helping customers build resilient infrastructure for the future.

As demand for reliable power continues to grow, we're ready to help power what's next.

Built to withstand heat, rain, snow, and extreme environments.

Generator enclosures must perform through changing weather, demanding environments, and unexpected utility interruptions while protecting the equipment inside.

That's why durability, corrosion resistance, airflow management, and quality engineering remain essential to long-term system performance.

Strong design begins with thoughtful engineering.

Today we remember September 11, 2001, and honor the nearly 3,000 lives lost. We're deeply grateful for the first responders and recovery workers whose selfless courage and dedication showed us the best of humanity.

We also recognize the lasting impact on the families and communities affected by these tragic events. In their memory, we honor the strength they displayed.

Large-scale data centers require more than off-the-shelf solutions.

Typically, no more than two facilities share the exact same environmental conditions, electrical requirements, or operational goals.

That's why custom engineering remains essential for today's mission-critical infrastructure.

Whether addressing airflow, acoustic performance, weather protection, or installation requirements, engineered solutions help ensure power systems are ready when they're needed most.

Because every project deserves a solution built around its unique challenges.
