SONI Ltd

SONI is the System Operator for Northern Ireland. We operate the electricity transmission system in Northern Ireland, also known as the grid, and plan for its future. 

We don't generate or sell electricity. Our role is to ensure that power can flow safely, securely and reliably from where it is generated to where it is needed. Every second, our experienced grid engineers balance the demand and supply of electricity from our Control Centre.

We also have an important role in planning for Northern Ireland's future energy needs.
