Battery systems, the energy storage solution of the future
The rise of intermittent renewable energy sources is amplifying the need for reliable, flexible storage solutions, to which battery energy storage systems (BESS) provide an effective response. VINCI Energies companies are engaged in many projects in this area. In 2025, they signed contracts to build and operate two storage systems in Sweden, to participate in the construction of a BESS in Vale de Moura, Portugal (to be connected to an existing solar power plant) and to build an electric substation to power a storage system in the Netherlands (photo above).
The total installed capacity of BESS in Europe was 2.6 GW in 2021. It is expected to reach
23.3 GW by 2031.

HVDC converters are set for success
High-voltage direct current (HVDC) converters play a pivotal role in electricity transmission by transforming the alternating current supplied by wind turbines into high-voltage direct current, which can then be carried by submarine cables to onshore stations. From there, it is converted back to alternating current and fed into the grid. In 2025, VINCI’s Energy Solutions business lines participated in the construction of several of these crucial links in the energy supply chain. With VINCI Construction, Omexom (VINCI Energies) won a contract to build two onshore HVDC converter stations for the transmission system operator RTE. Meanwhile, Cobra IS is involved in several major converter platform projects in the North Sea (photo above).
