Share the page

We are consulting on proposed modifications to the RIIO-2 Regulatory Instructions and Guidance (RIGs) and Regulatory Reporting Pack (RRP) for the Electricity System Operator (ESO).

We are proposing a number of modifications to the RIGs and RRP to reflect the costs relating to the New Roles, FSO Transition costs, National Grid payments and the introduction of the fixed BSUoS tariffs.

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