WindGrid is a subsidiary of Elia Group that focuses on developing, building, owning and operating electricity transmission infrastructure to support the energy transition in Europe and beyond. It concentrates on offshore and cross-border assets, including transmission lines, interconnectors and grid connections to offshore generation assets. In this work, WindGrid draws on Elia Group’s decades of experience in offshore transmission through its Belgian and German transmission system operators, Elia and 50Hertz, which together have around 5 GW of offshore transmission infrastructure in operation and about 15 GW of projects at various development stages across the North and Baltic Seas. Within Elia Group’s portfolio of non-regulated activities, WindGrid is positioned as the vehicle to expand overseas activities and contribute to the development of offshore electricity grids in Europe and internationally.
WindGrid’s capabilities span project development, construction and operation know‑how, energy sector networks, regulatory expertise and system and market modelling. Its team originates, designs, permits and develops large‑scale transmission projects, underpinned by close relationships with governments, regulators, grid operators, equipment manufacturers and renewable energy developers in Europe and the United States. Flagship projects include HansaLink, a hybrid HVDC interconnector linking Scotland and Germany and integrating up to 4 GW of offshore wind in phases, and a proposed HVDC hybrid interconnector between Ireland and Great Britain; both have been included in ENTSO‑E’s Ten‑Year Network Development Plan, with HansaLink also designated a Project of Mutual Interest. In North America, WindGrid has entered into memoranda of understanding with NextEra Energy Transmission MidAtlantic to collaborate on offshore transmission for New Jersey and with PPL Corporation to develop transmission solutions that connect future offshore wind capacity to the onshore grid in New England. WindGrid also supports policy and regulatory development around offshore hybrid assets in the UK and participates in EU and US fora to help shape frameworks for meshed offshore networks and hybrid interconnectors, aiming to deliver coordinated, reliable and cost‑effective offshore transmission that enables large‑scale renewable integration and decarbonisation.
