Value of Lost Load (VoLL) study

We have undertaken an investigation of the Value of Lost Load (VoLL) to inform our expenditure decisions and regulatory applications.

VoLL represents the economic value, in dollars per MWh, that a consumer places on electricity they plan to consume but do not receive because of a power interruption.  It is different in concept to the price consumers pay in the wholesale and retail markets for electricity.  Both the wholesale and retail prices reflect consumers’ demand for electricity, whereas VoLL reflects consumers’ demand to avoid power interruptions and its consequences. 

Auckland Strategy Final Report

Auckland is changing. Rapidly. Roads, housing, technology, industry and electricity.

Our Auckland Strategy looks specifically at the importance of electricity transmission into and across Auckland today and into the future.

Our capacity for meeting Auckland’s future electricity needs is very good, and we can meet all demand and growth projections for the next 30 years.

We also need to keep the grid in great shape and we have an extensive maintenance programme on our existing 220kV lines over the next 30 years. We are planning for this work now.

Securing our energy future - RCP3 consultation document

This consultation document includes 20 questions on which we are seeking your input and feedback. We will be collecting your views prior to our formal proposal submission to the Commerce Commission on 3 December 2018.
