Central North Island Upgrades - history
Transpower initiated consultation on the Central North Island (CNI) and Bunnythorpe-Haywards (BPE-HAY) thermal upgrades.
These two proposals were originally submitted as Part 4 of the 2005 GUP
As these were to be considered as economic investments, Transpower was responsible for consulting with affected parties. Once Transpower completed its consideration of the submissions it received, it submitted the proposals to the Commission for approval.
On 19 March 2008, Transpower wrote to the Commission suggesting a timetable for consultation and approval of the CNI and BPE-HAY investments.
In its response, the Commission determined the timetables for consideration and approval of those investments. These are discussed in the sections below.
