East-West Interconnector Between Ireland and Wales Opened

21 September 2012
Connected Grids of Ireland and Wales

The East-West Interconnector, a 500 MW ±200 kV HVDC light transmission system providing a connection between the electrical grids of the Republic of Ireland and Britain, has been officially opened with commercial operations due to commence on the 1st October.

The Interconnector will permit the trading of electricity between the Republic of Ireland and Great Britain and was built as part of a €600m investment by the RoI transmission system operator EirGrid. The Interconnector is now the largest energy infrastructure installation to be built in Ireland since the Ardnacrusha Hydroelectric Power Station in 1929.

The overall contract was awarded to ABB who in turn appointed Doran Consulting to lead the design team and provide structural design services in relation to the project buildings. The RoI site is located at Woodland, Co Meath and the GB site is located at Sholton in Flintshire, Wales.
