Release No. 52
Draft decision on Powerco’s application for major electricity network upgrade
The Commerce Commission has today released its draft decision on electricity lines company Powerco’s proposal for a
major network upgrade.
In June 2017, Powerco applied to the Commission to increase its prices to allow it to replace ageingassets in its
network and meet projected increases in demand for electricity.
“We have carefully assessed Powerco’s proposal. We accept that the company is facing significant challenges as a result
of a network built in the 1950s and 60s nearing the end of its life and under increasing pressure from powering regions
with strong population and economic growth such as Tauranga,” Commissioner Stephen Gale said.
The Commission’s draft decision proposes to allow Powerco to spend $1.27 billion over the next five years, a third more
than the past five years, and to recover this increased spending from consumers over the longer term. This increase in
spending would raise the average residential monthly electricity bill by about $2.70 in the next five years, and an
additional $6 in the longer term if current demand and investment forecasts eventuate.
“We are conscious of keeping electricity affordable. However, long-lived assets like electricity networks require
significant upfront investment, with the full costs recovered over their expected lifetime. We believe this is in the
best interests of today’s consumers, as well as future generations,” Dr Gale said.
“We are satisfied that the proposed investment is necessary to maintain a safe, secure and resilient network while being
mindful of emerging technologies like solar panels and battery storage.”
Dr Gale said the draft decision proposes that Powerco will have to report annually, both to the Commission and to public
meetings on how its investment is tracking against its proposal.
“A priority for the Commission will be how Powerco is improving its asset management practices over the course of the
upgrade.”
The Commission welcomes feedback on the draft decision by email to powercocpp@comcom.govt.nz by15 December 2017. Cross-submissions will take place in January and a final decision is expected to be released by 29
March 2018.
The proposed new prices and quality standards would apply for a five year period, starting 1 April 2018.
