General – HVDC Cables
Transpower from New Zealand announced it has secured global cable solutions supplier Prysmian to replace its high voltage direct current (HVDC) submarine electricity cables that link the North and South Islands.
Acting Chief Executive John Clarke said securing a supplier to manufacture and install the cables is a significant milestone for Transpower’s future work program.
“Replacing and enhancing ageing electricity infrastructure is a priority for Transpower, ensuring New Zealanders can rely on a secure electricity supply even as electricity use grows,” Clarke said.
The existing cables reach the end of their expected 40-year life in 2032 and require replacement to ensure bulk electricity – as much as 15% of New Zealand’s power use – can be transferred reliably between the two islands.
Replacement cables are a once-in-a-generation investment and will safeguard inter-island power transfer for another 40 years, following expected installation in 2031 and commissioning in 2032.
