RIIO-ED1 network price control

The RIIO-ED1 price control set the outputs that the 14 electricity Distribution Network Operators (DNOs) need to deliver for their consumers and the associated revenues they are allowed to collect for the eight-year period from 1 April 2015 to 31 March 2023.

RIIO-ED1 is the first electricity distribution price control to reflect the new RIIO (Revenue = Incentives + Innovation + Outputs) model for network regulation. RIIO is designed to drive real benefits for consumers. It provides the companies with strong incentives to step up and meet the challenges of delivering a low carbon, sustainable energy sector at value for money for existing and future consumers.
 
In February 2014 we published our decision to settle Western Power Distribution's price control early (termed 'fast-tracking'). We issued WPD’s licence conditions for RIIO-ED1 in May 2014.

In November 2014 we published our final settlements (final determinations) for the 10 companies remaining in the process. We issued their licence conditions implementing these determinations in February 2015.

Elements of the RIIO-ED1 price control were appealed to the Competition and Markets Authority (CMA) by a supplier, British Gas (BG) and a DNO, Northern Powergrid (NPg). The CMA published its decisions in September 2015. It upheld part of one of BG’s five grounds, and one of NPg’s three grounds. The decision on BG’s appeal applies to the 10 slow-track DNOs. NPg’s decision only applies to its two licensees. We have amended the licences according to the CMA’s orders, which we have published for reference below. The latest version of the licences can be accessed from the electronic public register.
