With recent Brexit polls in the UK showing the Leave side just ahead, I wonder what this will mean for the North South Interconnector project. Should UK leave the EU, then Northern Ireland will be free to decide how they deal with their generation capacity shortage themselves. Currently, EU Regulations are forcing restrictions on fossil fuel plant in Northern Ireland and diverting investment to unreliable renewables. Once outside the EU, NI could free themselves from these restrictions and simply build whatever conventional generation capacity is required to fill their capacity shortage.
Under these circumstances, the € 286 million interconnector project would be lying idle most of the time. If anything, Ireland would be importing the cheaper electricity from NI, not the other way around as is the current intention.
The justifications for this project are seriously undermined in the event of Brexit.
