The business units that operate under the Omexom brand in close to 40 countries enjoyed sustained growth in 2025, driven in particular by the electrification shift. Massive investments will be needed to modernise and extend ageing networks in order to address the increase in global demand for electricity by 2050. More than 40 million km of high-voltage lines will have to be reinforced or rebuilt. Energy storage sites, which are vital to ensuring stable and flexible electricity grids, are also being deployed rapidly. Omexom is strengthening its role as an international player by building high-voltage direct current (HVDC) converter stations to facilitate energy transmission. The digitalisation of distribution grids, which is essential to speed up decarbonisation, also heightens the risk of cyberattacks, a threat that Omexom can address with effective and integrated responses by combining its expertise with that of Axians. Omexom is growing organically in these buoyant markets while it continues to incorporate new companies. In 2025, VINCI Energies for instance acquired EnergoBit (€120 million in revenue, 925 employees), a leading player in energy infrastructure (engineering and installation of transformer substations, electricity transmission and distribution lines, network monitoring and automation) in Romania, a country with significant needs in terms of energy transition and infrastructure modernisation.
Lastly, Omexom continues to decarbonise its operations. In Bönnigheim (Germany), Netze BW and Omexom have been testing an all-electric “worksite of the future” equipped with zero-emission excavators, trucks and drilling rigs, thus reducing the worksite’s carbon footprint and noise level while helping to demonstrate that it is possible to modernise electricity grids while protecting the environment.
- In France, VINCI Energies is building the country’s second-largest ground-mounted photovoltaic plant for Photosol (200 MWp). Located on a disused military airbase in Creil (northern France), it will feature 350,000 photovoltaic panels capable of producing around 188 GWh of renewable electricity, enough to power 85,000 homes. In addition, following on from the award of the Biscay Gulf HVDC interconnection contract in June 2023, Omexom and VINCI Construction won a new strategic contract for the construction of a ground-based HVDC converter station, on RTE’s Centre-Manche 2 project, to connect offshore wind platforms to the onshore electricity grid.
- In the UK, VINCI Energies was awarded the contract to build an electricity substation for Scottish and Southern Electricity Networks (SSEN), including the study, design and supply of all the equipment needed for the St Fillans substation in Scotland. Also for SSEN, crews are carrying out the construction, installation and commissioning of the 400 kV Emmock air-insulated substation near Tealing.
- In Sweden, VINCI Energies signed two EPC (engineering, procurement and construction) contracts for the construction and operation of two BESS (battery energy storage systems) for Centrica, a British company. VINCI Energies will construct and commission four substations, and the 10-year operation and maintenance contract is set to run from 2026 to 2036.
- In Germany, network operator UKA Netz awarded VINCI Energies a contract for the construction, delivery, installation and commissioning of a standard 110 kV wind power substation.
- In the Netherlands, VINCI Energies will be responsible for the design and construction of a 150/33 kV electrical substation that will be connected to the BESS in the south of the country.
- In Spain, VINCI Energies built the common infrastructure for the electricity substation and additional installations for two photovoltaic power plants at La Solana (Ciudad Real), for Solana Renovables.
- In Portugal, Hyperion awarded VINCI Energies the Vale de Moura BESS project (6 MW/24 MWh). The contract includes the engineering, supply and connection of the storage system to the existing solar power plant.
- In the Middle East, VINCI Energies is expanding three 400 kV substations in the United Arab Emirates and Saudi Arabia, with a view to deepening grid interconnection between Gulf countries. Delivery is slated for 2027.
- In Africa, in Côte d’Ivoire, the company signed a turnkey contract for the construction of a 52 MWp photovoltaic power plant in Sokhoro. Developed by an independent operator, it stands to become the largest solar power plant in the country, producing around 90 GWh per year, enough to meet the needs of more than 370,000 people. In Cameroon, VINCI Energies has delivered a hybrid photovoltaic microgrid in the city of Yaoundé to power 100 smart streetlights, slashing municipal lighting energy consumption by 90%.
- In Asia, where data centre projects are multiplying, VINCI Energies is fitting out electrical substations designed to power these facilities in the greater Jakarta area (Indonesia). In Singapore, the company is carrying out electrical installation work for an 11-storey, 200 MW data centre. The project, which is due for completion in April 2026, employed some 600 people in 2025.
- In New Zealand, VINCI Energies won the contract to operate and maintain the electricity distribution grid for the city of Wellington.
- In the United States, Chain Electric is building a 69 kV transmission line over 38 km in Texas for the South Texas Electric Cooperative.
