Bunnythorpe-Haywards A and B lines conductor replacement investment proposal

On 8 November 2013, Transpower submitted a major capex proposal and seeks our approval to upgrade the Bunnythorpe Haywards lines A and B. Transpower is seeking $161 million dollars in 2020 prices.

Transpower has advised that the conductors of these lines have reached the end of their economic live and need to be replaced. Under the regulatory rules, Transpower can replace the existing conductors and maintain the existing capacity of the lines under its base capital works programme but has to seek approval from the Commission if it wants to increase the capacity of the lines.

Transpower's analysis shows that there are economic benefits in increasing the capacity of these lines. Transpower plans to use this opportunity to upgrade the lines and thereby increase their capacity.

Earlier, on 13 December 2011, Transpower submitted to the Commission a grid upgrade plan for an economic investment to upgrade Bunnythorpe Haywards lines A and B. Transpower has since reviewed the scope and expected cost of the project and has decided to re-apply for approval under the Transpower Capital Expenditure Input Methodology.

The Commission approved the proposal on 9 May 2014. The final decision can be found below.
