25 Years of Energy Infrastructure

Omexom History

A quarter-century of projects, partnerships, and expertise — shaping the infrastructure that powers communities worldwide.

The Omexom history spans 25 years of building the infrastructure that keeps the world connected and powered.

Since its early days, Omexom has grown from a regional service provider into a global specialist.

Today, Omexom operates across continents and technologies: from floating solar farms in France to digital substations in Senegal, from freshwater cabling in Finland to 500 kV substations in Indonesia. Each project is part of a longer story — one that reflects how energy systems have evolved, and how Omexom has evolved with them.

Across 36 countries and five continents, thousands of colleagues, clients, and partners have shaped what the brand is today — not just through projects, but through shared expertise, shared values, and shared ambition.
