Elia Group SA/NV is a European transmission system operator (TSO) responsible for planning, building, and operating high-voltage electricity grids. The company's core operations are concentrated in Belgium, where it operates the national transmission grid, and in Germany, where it holds a controlling 60% stake in 50Hertz Transmission, one of the country's four major TSOs. Elia Group's primary business model revolves around moving electricity from power generators—including offshore and onshore wind farms, solar installations, and traditional power plants—to local distribution utilities and large industrial users.
The company generates the vast majority of its revenue through regulated transmission tariffs, which are approved by national energy regulators and provide a return on its regulated asset base. Its operations are divided into three main segments: Elia Transmission (Belgium), 50Hertz Transmission (Germany), and Non-regulated Activities and Nemo Link. The non-regulated segment includes the Nemo Link interconnector (a subsea cable connecting the UK and Belgian grids), offshore grid development projects, and international energy market consultancy services. Elia Group is investing in grid modernization and cross-border interconnectors to integrate offshore wind power and maintain grid stability.
