Transmission grids are often interconnected so that energy can flow from one country to another. This helps provide a safe, secure, reliable and affordable energy supply for everybody. EirGrid Interconnector Limited (EIL) owns the East West Interconnector linking the electricity grids in Ireland and Great Britain. We sell capacity on the East West Interconnector through auctions.
The East West Interconnector is a 500 MW High Voltage Direct Current (HVDC) link between the electricity transmission grids of Ireland and Great Britain. At 500 MW it is one of the largest voltage source conversion (VSC) HVDC links in operation worldwide.
