Billion-Dollar Rescue for Australian Aluminum Smelter

Written by Martin Lynch, European News Editor for IIR News Intelligence (Sugar Land, Texas)

Summary

Metals and minerals major Rio Tinto has secured a AUD$2 billion (US$1.4 billion) rescue plan from the Australian government for its Boyne aluminum smelter in Gladstone, Queensland.

Future Guaranteed to 2040

The Australian government has stepped in with a AUD$2 billion (US$1.4 billion) rescue plan for the country's second largest aluminum smelter in Gladstone, Queensland.

The funding will be supplied 50:50 by the federal and local Queensland governments to help the Rio Tinto-owned Boyne smelter transition to renewable energy over a 10-year period, 2030-40. The company said that the financing will ensure that it remains internationally cost-competitive beyond its current power contract, which expires in 2029. Rio Tinto has agreed to underwrite AUD$7.5 billion (US$5.3 billion) of new wind, solar and battery storage development in the Gladstone region, which it will contract to supply the Boyne smelter going forward through a series of power purchase agreements (PPAs). 

Not the First Rescue

Last December, Industrial Info Resources reported that the Australian federal and local New South Wales (NSW) governments had agreed on a plan to save the country's largest aluminum smelter from closure. Also owned by Rio Tinto, the 590,000-tonne-per-year Tomago aluminum smelter in Hunter Valley had faced potential closure in the coming years over rising energy costs.

The Labor-led government is determined to maintain the country's industrial production capabilities. Last year it offered financial aid to Nyrstar's lead and zinc smelters in Port Pirie and Hobart, Glencore's Queensland copper smelter and refinery as well as a bailout for the failed Whyalla steelworks. 

Boyne Smelter

The smelter located on Boyne Island is operated by Boyne Smelters (BSL), which is majority-owned by Rio Tinto and has been in business since 1982 with an annual capacity of more than 500,000 tonnes of aluminum. The smelter connects via a conveyor belt to the Queensland Alumina Limited Refinery, which supplies alumina that is smelted into aluminum at BSL. Employing more than 1,000 people and thousands more indirectly, the smelter is the largest power user in Queensland, but its main source of power, the 1,680-megawatt (MW) Gladstone coal-fired power station, will be shut in 2029. It also supplies power to the Yarwun and Queensland alumina refineries. In Queensland, Rio Tinto has contracted more than 2.8 gigawatts (GW) of new renewable energy and more than 600 MW storage capacity from five projects since January 2024. 

"Slam Dunk" for Australian Industry

"This is the biggest industrial investment decision in Queensland's history," said  Federal Minister for Industry and Innovation Tim Ayers. "This is a 'future made in Australia' decision that delivers 3,000 jobs [1,000 direct and 2,000 indirect] in Gladstone and central Queensland, secures investment in this facility, helps us build economic resilience, and will push electricity prices down." Speaking to reporters he added: "It is a slam dunk, the economic case for this investment: it's good for productivity, it's good for economic resilience, it invests in electricity generation, it drives costs down, lifts productivity up, and makes Australia stronger."

Rio Tinto Chief Executive Jérôme Pécresse added: "This...partnership will ensure Boyne Smelter remains internationally competitive, strengthens the Australian aluminum sector for the future and supports the transformation and decarbonisation of the Queensland energy system. As fossil fuels become increasingly expensive, this investment, combined with the power purchase agreements we have already signed, positions Boyne to be among the world's first aluminium smelters underpinned by solar and wind power."
