Bombay-Otahuhu Regional Investigation

Region Map

What we are doing?

Transpower has identified a series of related needs associated with our 110 kV network primarily in the geographical region between Otahuhu and Bombay, but also as far south of Hamilton.  We are investigating potential transmission and non-transmission solutions to meet these needs simultaneously.

Why are we doing it?

There are a number of issues that require resolution or attention in the area over the next 5-15 years including: deteriorating condition of the conductor (wire) on the Bombay–Otahuhu, Bombay–Meremere 'A', Hamilton–Meremere 'B' and Meremere–Takanini 'A' lines; capacity constraints on the Otahuhu–Wiriwire line; and widening of the Southern motorway between Papakura and Bombay.

We have released a request for proposals from non-transmission proponents.  Register your proposal by 24 July 2019.
