Mossburn Substation

Decom and Powernet

Southland, New Zealand

Meridian Energy White Hill wind farm feeds power into the Powernet 66kV circuit that passes the site. With the development of the wind farm, Powernet took the opportunity to expand their nearby Mossburn Substation.


Calibre provided civil and structural engineering design and detailing services for formation, drainage and security fencing of the new yard; foundations for the new equipment and the new transformer including oil containment facilities; foundations, chambers and drainage associated with the oil separator installation; tubular steel communications pole; foundations for the communications pole; and modifications to the existing switchroom.

Our team obtained land use consent for the works and have previously obtained approval from the regional council for discharge as a permitted activity.
