RIIO-GD1 network price control

RIIO-GD1 is the first gas distribution price control review to use the RIIO model (Revenue = Incentives+Innovation+Outputs) of network regulation. 

The RIIO-GD1 price control sets out the outputs that the eight Gas Distribution Networks need to deliver for their consumers and the associated revenues they are allowed to collect for the eight-year period from 1 April 2013 until 31 March 2021.

The RIIO model of network regulation 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.
