Three energy companies (Northern Powergrid (Northeast) Limited and Northern Powergrid (Yorkshire) plc and British Gas Trading Limited) have sought permission from the Competition and Markets Authority (CMA) to appeal against Ofgem’s price controls for electricity distribution companies.

The price controls were announced back in November 2014 and will see the big six energy companies spend around GBP 24 billion in total to renew, maintain the electricity network and connect small-scale renewable generation. The current price controls expire on 31 March 2015, with the new controls set to run from 1 April 2015 - 2023.

Ofgem also set challenging targets for all companies to continue improving reliability, speed up new connections to the network and increase their work with vulnerable consumers.

The CMA must now decide whether to grant permission to appeal, and if it does so, it then has six months to determine the appeals. A further update will follow in due course.
