Global mining company Rio Tinto signed a power purchase agreement (PPA) with Windlab for the supply of renewable electricity at its Gladstone aluminum operations in Queensland.

Under the 25-year agreement, Rio Tinto will buy 80% of all power output from Windlab’s planned 1.4GW Bungaban wind energy project, which is currently in early development stages. The remaining 20% of the power will be supplied to Australia’s National Electricity Market, delivering clean electricity to homes and businesses.

After obtaining relevant approvals, the construction is expected to begin in late 2025 and the electricity can be generated by 2029.
