What is waste heat power in a data center?

Waste heat to power refers to recovering thermal energy that would normally be rejected from a data center and using it to generate useful on-site power. Instead of treating heat only as a cooling burden, this approach turns part of that thermal output into additional infrastructure value.

Why does waste heat recovery matter more for modern data centers?

It matters more now because AI workloads are increasing rack density, cooling demand, and pressure on grid capacity. As facilities become more power-intensive, operators need better ways to manage both heat and energy more efficiently.

Who is the SPRING platform designed for?

The SPRING platform is designed for hyperscalers, colocation providers, enterprise data center operators, and other high-density compute environments looking for more integrated approaches to power, cooling, and thermal efficiency.
