Aluminium smelter power supply deal paves way for second largest wind farm in NZ

One week after Rio Tinto sealed a groundbreaking electricity deal to power its New Zealand Tiwai Point aluminium smelter – and keep it from being shut down – plans to build a new 155MW wind farm have been given the all-clear.

NZ listed energy company Mercury said on Thursday it will proceed with the $486 million expansion of the Kaiwera Downs wind farm near Gore, on the South Island, off the back of the long-term agreement signed with Rio-owned New Zealand Aluminium Smelters.

The wind farm expansion will take the total capacity of the Kaiwera Downs wind farm to 198 MW, making it the second largest in New Zealand and capable to generate enough electricity to power the equivalent of around 73,000 homes per year.

As RenewEconomy reported last week, the deal to power the massive Tiwai Point smelter includes contracts with electricity generators Meridian Energy, Contact Energy and Mercury NZ to set pricing for an aggregate of 572 megawatts (MW) of electricity to meet the smelter’s full needs, backed by a mix of South Island renewables.

The 20-year deal is significant as it guarantees the future of the smelter, which accounts for around 13 per cent of all electricity demand in New Zealand, and which Rio Tinto had threatened to close.
