In September 2010 we launched Project TransmiT, an independent and open review of electricity transmission charging and associated connection arrangements. The aim of the project was to ensure that we have in place arrangements that facilitate the timely move to a low carbon energy sector whilst continuing to provide safe, secure and high quality network services at value for money to existing and future consumers.
As a result of this review, we decided in July 2011 to focus on changes to the transmission charging arrangements and, having consulted with industry, launched a significant code review in July 2011. The resulting modification (CMP213) was raised by NGET in June 2012. A workgroup of industry specialists was appointed to develop the detail of the changes in respect of the three issues outlined in our direction:
- better reflect the costs and benefits imposed by different types of generators on the electricity transmission network
- take into account the potential Scottish island links that are being considered
- take account of the development of “bootstrap” High Voltage DC (HVDC) links.
Industry developed a range of options for change and presented these to us in the Final Modification Report in June 2013. We issued an impact assessment and consultation on our minded-to position in August 2013. In light of the responses to this consultation, we issued a further consultation on additional new evidence in April 2014.
Having considered all the evidence, in July 2014 we decided to approve the option known as WACM 2 and implement this from April 2016. RWE’s appeal against this decision was dismissed by the Court on 23 July 2015. RWE have made us aware that they do not intend to intend to appeal the Court’s decision, and therefore the option will be implemented from April 2016.
