The North South Transmission Link project is part of EirGrid’s plans to upgrade the national electricity transmission system. It is a strategically urgent project that will remove restrictions limiting cross-border power flows between Ireland and Northern Ireland thus strengthening security of electricity supply throughout the island of Ireland.
On 27 March 2015 EirGrid published a new independently peer reviewed draft Strategy which found that there remains a clear need for the North South transmission line, and that the existing proposal for a 400kV overhead line remains the most appropriate solution for the project.
EirGrid and SONI periodically publish an All Island Generation Capacity Statement. In February of this year, the All Island Generation Capacity Statement 2015-2024 was published. The report examines the generation adequacy over a number of economic scenarios. These projections are based on economic forecasts published by the ESRI, namely the Quarterly Economic Commentary, published in October 2014 and the Medium Term Review, published in July 2013. The Statement confirms the necessity of the North-South transmission line based on its demand forecasts. The All Island Generation Capacity Statement is published on the EirGrid website.
