ABB delivered the East West Interconnector, the world’s highest capacity HVDC light underwater power link, to EirGrid, the Irish transmission system operator. The 500-MW transmission connection establishes a link between the Irish and U.K. grids, enabling cross-border power flows and enhancing grid reliability and security of electricity supplies. The new link also facilitates power trading between the two countries and connects Ireland to the European grid. As Ireland expands its wind power capacity, it can export surplus electricity to the UK, and can import power when required.
