Application of phase-shifting transformers for the enhanced interconnection between Northern Ireland and the Republic of Ireland

Abstract

NIE is the electricity transmission and distribution company for Northern Ireland, and the ESB is the electricity generating, transmission and distribution company for the Republic of Ireland. The AC interconnection of both electricity networks brings benefits to each company in the form of sharing the generation reserves, facilitating the liberalising of the electricity market in the island of Ireland and generally improving the quality and continuity of electricity to their respective customers.
