This document explains the processes that we follow whilst undertaking the cost assessments of electricity interconnectors and provides guidance to interconnector developers on how to prepare cost submissions for our review.
Alongside this guidance document we have also included the two documents associated with our Cap and Floor Regulatory Instructions and Guidance. We published these documents in December 2019, however, for ease of access we believe that it’s appropriate to also include these documents on this page. We have not updated these documents since December 2019.
