VCR estimates and transmission reliability

November 2016

We were engaged by TransGrid to determine Value of Customer Reliability (VCR) estimates suitable for customers experiencing low probability but high impact supply outages in the Sydney CBD and Inner Suburbs regions.  We were asked to determine these VCR estimates by drawing on existing, publicly available VCR studies.  The values we derived were $90/kWh for Inner Suburbs customers and $150-$192/kWh for customers in the Sydney CBD. 

IPART has subsequently adopted our $90/kWh estimate in recommending reliability standards to apply to the Inner Sydney transmission network from 1 July 2018, available here.
