Project TransmiT: Decision on proposals to change the electricity transmission charging methodology

Decision

Project TransmiT identified defects in the transmission charging methodology.  An industry led process was establish to address the defects which led to several options for change being identified.  In August 2013 we published a consultation and analysis of the impacts of these options, including our initial minded-to position.  We published a further consultation in April 2014 on new evidence that came forward in response to that consultation.

Following careful consideration of the evidence, including all the consultation responses, we have decided to approve the option known as ‘WACM 2’ to be implemented from April 2016 because it is more cost reflective than the current methodology and best meets our statutory duties.
