Transmission Line Hardware Contract Award to Electropar  ; NIGUP 400kV

New Zealand’s electrical transmission infrastructure continues to undergo a period of sustained investment to enhance its security and performance.

In 2008 owner and operator of New Zealand’s National Grid, Transpower NZ Ltd created an Alliance relationship with United Group and Balfour Beatty (called the “Transpower Alliance”). The Alliance has been created to deliver the North Island Grid Upgrade (NIGUP) project : design, supply and construction of a 400kV capable, 3 phase, 50Hz AC transmission line approximately 186km long.

The line runs from the central north island Whakamaru North Substation to the Brownhill switching station approximately 9km south of Otahuhu, Auckland although the Alliance’s scope excludes the actual substation works.
