SONI

SONI (System Operator for Northern Ireland) plans and operates the electricity transmission system. We bring electricity to every part of Northern Ireland and plan ahead for future growth. From our control centre in Belfast, we match supply and demand for power every second of every day by using the transmission system.

The transmission system, or grid, brings power from where it is generated to where it is needed and also powers NIE Networks’ distribution system, which in turn, supplies electricity to homes, farms and businesses.

SONI is independent from NIE Networks. Since 2014, SONI has been responsible for planning for the future of the grid, while NIE Networks is responsible for maintenance, repairs and construction of the grid.

Since 2009, SONI has been part of the EirGrid Group. SONI also operates the all-island wholesale electricity market with EirGrid through the Single Electricity Market Operator (SEMO) which has been in operation since November 2007. SONI is regulated by The Utility Regulator (UR). SEMO is regulated cooperatively by the Commission for Regulation of Utilities Water and Energy (CRU) and UR through the Single Electricity Market Committee (SEM-C).
