What Omexom UK does

Omexom UK is the UK and Republic of Ireland operating brand of VINCI Energies' Omexom network, legally registered as Powerteam Electrical Services (UK) Limited in Northern Ireland. The company delivers engineering, procurement, construction (EPC) and maintenance services for electricity transmission and distribution infrastructure across voltage levels from 33kV to 400kV, including overhead lines, underground cables, substations, HVDC interconnectors, and renewable energy integration (wind, solar, battery energy storage systems, hydro, nuclear lifecycle services). It operates through seven core business units — Transmission, Substations, Renewables, Power Solutions, Engineering, Distribution, Major Projects — plus a dedicated Ireland business unit, supported by the Omexom Institute training facility in Castleford.

Revenue is generated through project-based, design-build EPC contracts and long-term maintenance agreements awarded via competitive tender with Distribution Network Operators (DNOs), Transmission Operators (TOs), and renewable energy developers. Marquee customers include National Grid (Enterprise Delivery Partner on the £9bn Great Grid Partnership through the OTW joint venture with Taylor Woodrow; Hylton Castle 275kV substation), SSEN Transmission (ASTI framework projects including Fort Augustus 400kV upgrade and Kintore world-first 400kV G3 green gas substation), Scottish Power Renewables, and ABB (IFA 2 HVDC turnkey works). Adjacent offerings span local-authority outdoor lighting (DBOM energy performance contracts targeting 60% energy savings and 99% availability), EV charging infrastructure, and local energy grids. Distribution is exclusively direct enterprise field sales; no retail or self-service channels exist.

The business model is anchored in the UK energy transition: regulatory drivers (ASTI framework, net-zero mandates) and surging renewable connection demand are expected to sustain a multi-year capex supercycle across DNOs and TOs. Omexom UK leverages VINCI Energies' network of 425 business units across 36 countries for shared expertise and resources, while operating through a decentralised brand structure that incorporates legacy entities (Powell Engineering, Powerteam Electrical Services, NorPower). The 2023 NorPower acquisition and rebranding to Omexom in May 2026 demonstrate active consolidation within the UK overhead-line services market.
