Decision on two-year extension to the current SONI Price Control

The Utility Regulator has published a decision on the financial values necessary to extend SONI’s (System Operator for Northern Ireland) current price control by two years. 

In August 2023, following a public consultation, we published our decision to defer the start date of the next SONI price control by one year to 01 October 2026. In the intervening period, SONI subsequently requested a further year’s delay. The additional extension is to facilitate work associated with the governance programme and other key projects.

In February 2025 we published our consultation on the two-year extension and other minor modifications. We are now publishing our decision paper on licence modifications which will enable a two-year extension of the SONI Review of Prices (SRP20) price control final determination into the 2026-2027 tariff year. 

The SRP20 extension licence modifications will set the amount of revenue SONI will have to run its business for the two years beginning on 01 October 2025 and ending on 30 September 2027. Should no challenges be forthcoming, the licence modifications will take effect on 23 July 2025.
