Final decision

On 28 April 2017, we released our final decision on Powerlink's transmission determination for the 2017-22 regulatory control period. We also published a fact sheet to accompany and summarise our final decision.

Our final decision consists of an overview and eleven (11) attachments. As many issues were settled at the draft decision stage or required only minor updates we have not prepared separate final decision attachments for all elements of the decision. For ease of reference, those attachments we have included are numbered consistently with the attachment numbering in our draft decision.

On 11 May 2017, we updated the PDF version of attachment 3 (rate of return) on this page to correct minor formatting issues within the document.
