Interconnections
Like all transmission service operators across Europe, we aim to increase our connection to other grids. This will improve the stability of our electricity supply, and will increase competition. There are already two grid interconnectors between the island of Ireland and Great Britain - East West Interconnector and Moyle Interconnector. Find out more.
