Decision on modifications to the ESO Regulatory Instructions and Guidance and Regulatory Reporting Pack for RIIO-2

Decision

On 22 May 2024, the Authority issued a Notice proposing modifications to the RIIO-2 RIGs and the RRPs for Electricity System Operator (ESO). We are now publishing the modified versions of the RIIO-2 RIGs and RRPs following the receipt of stakeholder feedback on the Notice.

These modifications are made to reflect the costs relating to the New Roles, FSO Transition costs, National Grid payments and the introduction of the fixed BSUoS tariffs. We outline these modifications in our Decision Notice.

The modifications will take effect from 25 July 2024.

The RIGs are tracked to show the location of modifications relative to previously published versions.
