Two Energy Pacts Put Ireland at Europe's Grid Frontier

Ireland signed dual energy MoUs with Spain and the UK at WindEurope Madrid, advancing a direct electricity interconnector study

16 Jun 2026

Ireland signed two energy cooperation agreements on April 23, 2026, at the WindEurope conference in Madrid, committing to study a direct electricity link with Spain while extending its existing framework with the United Kingdom. Climate Minister Darragh O'Brien signed both memoranda alongside counterparts from each country.

Under the Spain agreement, EirGrid, Ireland's state grid operator, will work with Redeia and its subsidiary Red Eléctrica to assess the technical and commercial feasibility of a subsea power cable between the two countries. The UK deal extends an existing bilateral cooperation framework, maintaining a second trading corridor.

Cathal Marley, chief executive of EirGrid, described the Spain study as "a significant step for the development of our systems" and "essential to delivering a secure, low-carbon energy system."

A live Ireland-Spain cable would allow surplus offshore wind power to flow south, reducing the need for gas-fired backup generation across both systems. Parallel engagement with the UK limits the risk of energy isolation that has shadowed Britain's exit from the EU's single electricity market.

Broader timing sharpens the strategic context. Ireland assumes the rotating EU Council presidency in late 2026, placing its ministers at the centre of bloc-wide energy policy discussions at the moment feasibility results are expected to emerge. Few comparable economies will hold equivalent leverage over grid integration decisions in that window.

The feasibility study has no confirmed timeline or cost estimate. Subsea interconnectors of this scale typically require several years of engineering review, permitting, and financing before construction can begin. Both Spain and Ireland have committed public targets for offshore wind expansion, but neither has yet identified the transmission capacity needed to export surplus generation at scale.
