During RPI-X@20 we undertook 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.
On 4 October 2010, the Gas and Electricity Markets Authority (GEMA) published its ‘Decision’ document to implement a new regulatory framework, known as the RIIO model (revenue = incentives+innovation+outputs). The RIIO model has been designed to promote smarter gas and electricity networks for a low carbon future. To draw the RPI-X@20 project to a close we have published three documents:
• The RPI-X@20 ‘Decision’ document: our final decision on the RIIO model;
• The Handbook for implementing the RIIO model: sets out ‘how’ the RIIO model will work in practice; and
• A Guide to Price Control Modification References to the Competition Commission: sets out how stakeholders can raise concerns to us about our price control decisions.
Over the course of the RPI-X@20 review we published several consultation documents before reaching our final decision on the RIIO model. These have been informed by, among other things, a series of working papers, consultancy reports and significant engagement with stakeholders – including via the 'RPI-X@20 web forum'.
All relevant documentation related to the project is contained within the categories on the left hand side of this page. For a list of the documents produced during the review please click here.
The RIIO model will first be applied in the transmission (RIIO-T1) and gas distribution (RIIO-GD2) price control reviews which are due to be implemented in April 2013.
