Work starts on Celtic Interconnector as ship arrives in Cork to lay underwater cable

Once fully installed, the entire 575km Celtic Interconnector will run from East Cork to the north-west of Brittany and will allow for the exchange of 700MW of electricity - enough to power some 450,000 homes

A specialist marine vessel, Calypso, arrived from Norway into the Port of Cork this week.

Work laying the underwater cable for the first electricity interconnector between Ireland and mainland Europe has begun.

It marks a major milestone in the huge €1bn Celtic Interconnector scheme to link the electricity grids of the two countries.
