What we do
SONI is Northern Ireland's electricity grid operator. We ensure power can flow to where it is needed in the present and plan for a cleaner energy future.
Operating the grid
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.
Electricity is also a key to decarbonising our society and economy to meet Northern Ireland's climate climate action goals. We are transforming the grid and how we operate it in an unprecedented way to support a cleaner, more secure energy future for everyone in Northern Ireland.
Working together
Our electricity system is complex and involves many organisations with different responsibilities - from electricity generators, to grid operators, to regulators, to electricity suppliers. Everyone has a role to play.
As Northern Ireland's Transmission System Operator, we understand that local communities, landowners, businesses and industry partners must be at the heart of this unprecedented change.
We know that we can only achieve this once-in-a-generation energy transition by working together.
