Rio Tinto has signed a new power purchasing agreement (PPA) which will see the company buy the majority of electricity from Windlab’s planned 1.4GW Bungaban wind energy project to supply its Gladstone operations.

The agreement, which follows the announcement last month of a PPA for the Upper Calliope solar farm in Queensland, will mark another step in Rio Tinto’s work to repower its Gladstone production assets – the Boyne aluminium smelter, Yarwun alumina refinery and Queensland alumina refinery.

Under the new PPA with Windlab, Rio Tinto will buy 80 per cent of all power generated from the Bungaban wind energy project over 25 years. 

The project, which is currently in early development, is set to be built and operated by Windlab at a site in Queensland about 40km from the town of Wandoan, and 290km south-west of Gladstone, subject to development and grid connection approvals.

The remaining 20 per cent of the project’s generated electricity will supply Australia’s National Electricity Market, delivering clean electricity to homes and businesses.

The PPA is the second renewable power deal signed for Rio Tinto’s Gladstone operations, after the recent agreement signed with European Energy to drive development of the 1.1GW Upper Calliope solar farm.

Once developed, the combined 2.2GW of renewable PPAs with Windlab and European Energy have the potential to lower carbon emissions by about five million tonnes per year and could generate the equivalent of ten per cent of Queensland’s current power demand.

The Bungaban PPA is set to bring more renewable power into Rio Tinto’s Gladstone operations and marks another step towards the company’s climate goal of halving its global Scope One and Two carbon emissions this decade. 

If combined with more renewable power and suitable firming, transmission, and industrial policy, the Bungaban and Upper Calliope PPAs could also provide the core of a solution to repower Rio Tinto’s three Gladstone production assets.

Rio Tinto Chief Executive, Jakob Stausholm, said, “This agreement with Windlab builds on our momentum in our work to repower our Gladstone operations and provide a sustainable future for heavy industry in Central Queensland.

“The task remains challenging, but we have a pathway to provide the competitive, firmed power our Gladstone plants need and we are continuing to work hard with all stakeholders, including the Queensland and Australian governments, on getting there.”

Mr Stausholm said that competitive capacity, firming, and transmission, are critical to developing a modern energy system that can ensure more large-scale renewables development in Queensland and help guarantee the future of Australian industry.

Once approved, construction of the Bungaban project is anticipated to start in late 2025 and is expected to produce electricity by 2029, employ up to 600 people during construction and support up to 30 permanent jobs when operating.

Windlab CEO, John Martin, said, “Securing this PPA is a major milestone for the Bungaban project and a strong signal of the project’s value from the market.

“Windlab is very proud to be partnering with Rio Tinto to support the long-term sustainable future of Rio Tinto’s Gladstone operations.”

Mr Martin said that the agreement highlights the importance of large-scale renewable energy projects in shoring up Queensland’s powerhouse traditional industries – particularly minerals and advanced processing – which employ thousands of people in regional communities across the state and has a key role to play in Queensland’s low-carbon future.

“Bungaban is a key transition opportunity that will create up to 600 new Queensland construction jobs and inject around $500 million into the regional economy through local employment, supply and contracting.

“The project can be responsibly developed, grid connected and produce enough energy to power the equivalent of 740,000 Queensland homes by 2029, while eliminating about four million tonnes of carbon from the state’s generation profile every year.”

Rio Tinto will continue to engage with potential partners to assess other proposals to help competitively meet the energy needs of its three production assets in the Gladstone region. 

These assets require more than 1GW of reliable power to operate, which equates to over 4GW of quality wind or solar power with firming. Potential further electrification of plant processes could increase their electricity demand in the future.
