Mainzeal has been working closely with Siemens over the past 12 months on their bid to undertake a major component of the upgrade project of the HVDC inter-island link.
Transpower announced that they had awarded the principal contract for construction of Pole 3 of the high voltage direct current (HVDC) inter-island link to Siemens.
The Pole 3 project involves replacing the 44-year old Pole 1 equipment at Haywards substation north of Wellington and Benmore substation in the South Island with new, modern thyristor converters.
The project will increase the capacity of the overall HVDC link to 1000 MW in 2012 and 1200MW in 2014. Under the contract, Siemens will construct the converter stations at each end of the link, expand the 220 kV switchyards at both substations and build the new voltage support equipment at Haywards.
Mainzeal will be a subcontractor to Siemens, delivering the civil and construction works.
