About us

At the Centre of the Industrial Value Chain

Kiel Power Systems is a leading manufacturing partner for highly complex mechanical components and assemblies — purpose-built for the power infrastructure that drives today's most demanding applications. As global demand for AI compute, data centre capacity and reliable energy supply accelerates, we are at the centre of the industrial value chain that makes this growth possible.
We empower the global energy transition with mission-critical precision components — focussing on data centres and energy infrastructure, and also with expertise across marine & defence.
Our capabilities cover the complete value chain — from engineering support and CNC machining to assembly, quality assurance, logistics and aftermarket services. Whether prototype, low-volume or large-scale serial manufacturing, we provide tailor-made solutions for customers with the highest technical and regulatory standards.

One distinct megatrend is reshaping global energy demand
‍— creating exceptional opportunity for exactly what we build.

AI Driven Critical Infrastructure
& Data Centres
With the capability to machine components weighing up to 100 tonnes — complemented by in-house metrology, material testing and project management expertise — we are the partner global industrial leaders turn to when it matters most.

Powering the Backbone of AI

From primary power generation to backup systems, we supply critical components across the full energy infrastructure. Reliable, resilient, and built for the demands of tomorrow's data centres.
“Our strength lies where others reach their limits: machining massive components with precision measured in microns.”
