Ó Gallachóir heralds the development of the all-island Single Electricity Market (SEM) as one of the “hidden giants” of greater all-island cooperation, 25 years after the signing of the Good Friday Agreement.

In 1995, the North South Electricity Interconnector was restored after almost 20 years of inaction and since then several significant electricity and gas infrastructure projects have been developed on the island, ranging from the commissioning of the Moyle electricity interconnector to Scotland in 2021 to the approval in 2018 of a second North South Interconnector.

MaREI Director and Associate Vice President of Sustainability at UCC Prof Brian Ó Gallachóir spoke with Claire Byrne on RTE Radio One on the 15th of January about the announcement by Electric Ireland to reduce their residential electricity prices by 8% from March.
