RPI-X@20 review

RPI-X@20 was a detailed review of energy network regulation. The review looked at how best to regulate energy network companies to enable them to meet the challenges and opportunities of delivering the networks required for a sustainable, low carbon energy sector.

The RPI-X@20 review resulted in our new RIIO regulatory framework, outlined in the RPI-X@20 decision document.

We also set out more details of how the RIIO model would work in practice in the Handbook for implementing the RIIO model.

Over the course of the RPI-X@20 review we published multiple consultation documents, a series of working papers, consultancy reports and presentations and notes from our engagement with stakeholders. These documents are set out below.
