The high-voltage network brings power from generators to supply the electricity distribution network. The grid powers every home, business, school, hospital, factory and farm in Northern Ireland. We are responsible for a safe, secure and reliable supply of electricity: now, and in the future.

We forecast when and where electricity is needed across Northern Ireland: hour-to-hour, day-to-day, and year-to-year. We work to ensure there is enough electricity for industry to prosper, and for employment to grow. Our work is essential today, as well as being a crucial investment for future generations.

Our Leadership is great

Our people dedicate themselves to a better transmission grid, for the benefit of all. We achieve this goal with a combination of expert skills from a wide range of experience. You can learn more about SONI's board and senior management here.


Working with us gives you the opportunity to be part of an organisation that is committed to delivering on our mandate of managing and operating the transmission grid across Northern Ireland. We offer a challenging yet collaborative and team-orientated work environment where high performance, knowledge and continual development are valued. Our aim is to attract and retain excellent staff.
