East-West Interconnector. This project will: enhance security of supply, facilitate increased competition, assist growth in renewable energy, enable direct access to the larger UK market.


Project Completion

The electricity link called the East-West Interconnector between the electricity grids of Ireland and Britain has now been completed.

The EirGrid East West Interconnector runs between Deeside in north Wales and Woodland, County Meath in Ireland. Approximately 260km in length, the underground and undersea link has the capacity to transport 500 megawatts – enough energy to power 300,000 homes.

The EirGrid Interconnector will carry electricity both ways, benefiting consumers by helping to improve security of supply, increase competitiveness and to encourage the growth of renewable energy generation.

We are absolutely committed to your safety at all times.

Full testing of the Interconnector during the testing phase confirmed that in operation, the Interconnector is well below the ICNIRP Guidelines for limiting exposure to time-varying Electric, magnetic, and electromagnetic fields, as endorsed by the Irish Government.

ICNIRP is the formally recognised non-governmental standard setting body for EMF by the World Health Organisation (WHO) and the European Union.

A number of independent reports health and safety reports were undertaken in relation to the Interconnector, see Project Activity

Planning Approval

An Bord Pleanála granted full planning permission to EirGrid in September 2009.

Construction of the interconnector commenced in July 2010 and is now complete.

We greatly appreaciated the patience shown by the local communities during the construction phase of the Interconnector.
