In 2016, we published our initial consultation on the 2018 periodic review (PR18). In connection with this, we subsequently published a number of working papers, including working paper 5 which explored options for the treatment of enhancements projects in control period 6 (CP6).
On 16 June 2017, we published a close-out report on working paper 5. This summarised the key points raised by stakeholders along with comments on these and next steps. The responses to the working paper have also been published.
