About

Vistergy Ltd is the governed intelligence layer between standards and decisions across nuclear, energy, data centres, and LNG.

The gap between when infrastructure is built and when it works is measured in years and billions of dollars. A nuclear plant handed over does not mean a plant generating. An AI factory or data centre commissioned does not mean a data centre serving workloads. An LNG terminal completed does not mean molecules flowing. Somewhere between the final weld and the first commercial operation, the system is still dark.

Vistergy exists to shrink that gap.

What we do
We fuse satellite observation with institutional data and international standards to produce calibrated intelligence that infrastructure decision-makers can act on. Our public artefact is Atlas, the open 3D reference for the facilities that generate energy and the facilities that consume it. Our publications work through the implications week by week. Our work with enterprises, regulators, and partners turns that intelligence into decisions.

Three layers, one thesis
1/. The artefact. Atlas at atlas.vistergy.com. Nuclear, LNG, and data centres on a single globe. Open to everyone, free forever.

2/. The thinking. The Vistergy Brief every Tuesday, the Permit to Operate podcast, and Still Dark when a subject needs depth.

3/. The capability. Governed agentic AI, standards-aligned intelligence, and expert-in-the-loop decision architectures. Delivered through consulting, partnerships, government frameworks, and enterprise channels.
The same governed agents are available as a managed service through IBM watsonx Orchestrate, or installed on an operator's own Red Hat OpenShift estate.
