Draft Determinations on RIIO-2 re-opener applications 2024: Electricity Transmission, Electricity Distribution and Gas Distribution

Share the page

As part of the RIIO-2 price control, network companies can apply for additional allowances via Re-opener uncertainty mechanism. Since January 2024, we received re-opener application submissions from twelve network companies. We are consulting on our Draft Determination and draft direction for these applications.

We would like views from people with an interest in electricity transmission, electricity distribution and gas distribution networks. We would also welcome responses from other stakeholders and the public.
