North/South Interconnector

The North/South Interconnector is a major infrastructure project which will link the Northern Ireland and Republic of Ireland electricity networks. Following a European Commission decision with respect to responsibility for planning investments for the Northern Ireland electricity transmission network, Northern Ireland Electricity Networks (NIE Networks) transmission investment planning activities transferred to the System Operator Northern Ireland (SONI) on 1 May 2014.

SONI also assumed responsibility for obtaining wayleaves and other statutory consents to permit the construction of new electricity transmission apparatus. This applies to the North/South Interconnector project.

This is a cross border project, requested by the Utility Regulators and Governments both in Northern Ireland and the Republic of Ireland. The project is vital to ensure the effective operation of an efficient 'all island' electricity market, to support the realisation of strategic renewable energy targets and to exert downward pressure on electricity prices for customers in Northern Ireland.
