Online Stakeholder Forum

The Online Stakeholder Forum allows you to contribute to the RIIO-ED1 price control review by providing us (and other stakeholders) with analysis and papers that can be posted here on our website. The price control team will also upload working papers for discussion – as well as relevant responses.

If you have a paper or document you would like to have posted here, please email RIIO.ED1@ofgem.gov.uk. We will review the documents first to make sure they are appropriate.
