SONI (System Operator for Northern Ireland) is the Independent Transmission System Operator for Northern Ireland.

We ensure that Northern Ireland has a secure, reliable and cost-effective supply of electricity. We provide a critical service to consumers, communities and to the economy.

Today SONI has published its Business Plan Submission for the upcoming Price Control period 2020-25.

Price controls are used by regulatory authorities, such as the Utility Regulator, to set the amount of money that can be received by companies like SONI over a particular period of time.

Almost all of SONI's income (>95%) comes from regulated price control processes.
