SONI aims to deliver quality to the customers and stakeholders that we serve. We respond to a wide range of needs across the wholesale energy sector and throughout Northern Ireland.
Some customers generate electricity, whether from conventional or renewable sources. Other customers have a high demand for electricity, which only our grid can provide. We also serve the suppliers and stakeholders with an interest in the transmission grid.

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.
