Unlocking gigawatts: how flexible colos make room for the AI buildout

The expansion of AI requires more than just high-performance chips—it requires massive amounts of physical power and space. But in most of the world's tech hubs, the grid's capacity is already maxed out.

How do we find gigawatts of new capacity without waiting decades for new power plants and cables? The answer lies in "Flexible Colos."

The Problem of "Stranded Capacity"

Traditional data center capacity is built on a "worst-case scenario" model. Every rack is allocated a fixed amount of power that it might use at absolute peak performance. However, most servers rarely hit that peak simultaneously.

This results in "stranded capacity"—power that is legally and technically reserved but never actually used. In a large colocation facility, this waste can add up to dozens of megawatts.

What is a Flexible Colo?

A flexible colocation data center (Flexible Colo) uses software to "overbook" its power capacity safely, much like an airline overbooks seats.

By monitoring power usage in real-time and having the ability to slightly throttle non-critical AI training workloads during rare peaks, these sites can fit 20-40% more serversinto the same building with the same grid connection.

Making Room for the AI Buildout

This flexibility is the key to unlocking the gigawatts needed for AI. It allows operators to:

  • Maximize existing sites: Add more racks to current facilities without needing expensive grid upgrades.
  • Support AI training: AI training workloads are often "delay-tolerant," meaning they can be slowed down for short periods without affecting the final result.
  • Lower costs for everyone: By using the infrastructure more efficiently, the cost per megawatt-hour drops, benefiting both the data center and the AI customer.

The Future is Software-Defined

The days of static, rigid power allocations are over. The next generation of data centers will be "software-defined"—where power flows dynamically to where it's needed most, and flexibility is baked into every contract.

At Cledion, we provide the intelligence layer that makes flexible colocation possible. Want to unlock the stranded capacity in your site? Let's build the future together.
