Sinn Féin has claimed Brexit will pose a "huge challenge" to the energy market in Ireland.
MLA Cathal Boylan said Brexit will undermine energy production on the island.
He said: "Changes to any of these elements of the energy market has the potential to affect every single local household.
"A hard Brexit has the potential to create higher prices for everyone. We need to ensure that the current infrastructures are maintained and enhanced, not fractured through Brexit."
