Rio Tinto signs Australia’s largest renewable power deal

Rio Tinto has signed Australia’s largest renewable power purchase agreement to date to supply its Gladstone operations in Queensland, agreeing to buy the majority of electricity from Windlab’s planned 1.4GW Bungaban wind energy project. The agreement, which follows the announcement last month of a PPA for the Upper Calliope solar farm in Queensland, will make Rio Tinto the biggest industrial buyer of renewable power in Australia and is another major step in the work to repower the company’s Gladstone production assets – Boyne aluminium smelter, Yarwun alumina refinery and Queensland Alumina refinery. Under the new PPA with Windlab, Rio Tinto will buy 80% of all power generated from the Bungaban wind energy project over 25 years. The project, which is currently in early development, will be built and operated by Windlab at a site in Queensland about 40 kilometres from the town of Wandoan, and 290 kilometres south-west of Gladstone, subject to development and grid connection approvals. The remaining 20% of the project’s generated electricity will supply Australia’s National Electricity Market, delivering clean electricity to homes and businesses.
