EC's Draft Decision On Transpower Application
Today the Electricity Commission has issued a draft decision to turn down Transpower’s proposal to build a new 400
kilovolt (kV) line between Whakamaru and Auckland. The Commission will make its final decision on the proposal in July.
Commission chair, Roy Hemmingway said, “Based on a wide range of advice and the analysis undertaken to date, there are
alternatives that provide the same level of electricity security but are less expensive than the proposed 400kV line.
Therefore, at this stage the Commission cannot approve the proposal.”
Mr Hemmingway said that Transpower’s grid upgrade proposal reflected good electricity industry practice in meeting grid
reliability standards, and the Commission was satisfied that Transpower had materially complied with processes set out
in the Electricity Governance Rules.
The Commission places the highest importance on an adequate and secure power supply to Auckland and Northland, Mr
Hemmingway said. It has already approved several transmission upgrades that would deliver improved security of supply in
the short and medium term.
Mr Hemmingway said that meeting Auckland and Northland’s expected power needs will require a major new transmission line
after the middle of the next decade, unless new generation is built close to Auckland or load growth declines.
“The form and timing of this investment will depend on the location of generation investment, demand growth and
transmission technology developments.
“We are also interested in peoples’ views on the desirability and practicality of acquiring a transmission corridor in
advance of the need for a new transmission line,” he said.
Mr Hemmingway said the Commission welcomed feedback on Transpower’s proposal and the draft decision from interested
parties and would consult widely with affected communities, key stakeholders and iwi before making its final decision in
July. There would be briefings in May, public hearings in June and a likely formal conference in early July.
“The Commission’s draft decision on Transpower’s grid upgrade proposal has been by far the most challenging activity of
the Commission since it started operating in September 2003. But the exercise has led to a greater public awareness of
Auckland and Northland’s power needs and considerable creative thinking about expanding transmission and generation. The
Commission received some thoughtful submissions on alternatives that contributed greatly to the quality of its work.”
