Revised SONI Regulatory Instructions and Guidance consultation published

Today we publish for consultation our proposals regarding the revision of the annual reporting requirements for SONI. This annual reporting guidance is known as the Regulatory Instructions and Guidance (RIGs).

The guidance requires updating to reflect changes made in the 2020-2025 SONI price control final determination. Additional reporting will also aid transparency of understanding with respect to movement in SONI’s cost base and price control delivery. 

The guidance sets out proposals for RIGs annual reporting of electricity transmission system operator (TSO) costs and outputs. It details the changes from the existing guidance, rationale for change and the expected effect. 

More information on the consultation and details on how to respond, can be found on our consultation page.
