Rio approves major solar farm in Cape York

January 25, 2024

Rio Tinto has approved a new 12.4 megawatt (MW) solar farm and battery storage for its Amrun bauxite operations near Weipa in Queensland.


The project is part of Rio Tinto’s global decarbonisation strategy and ongoing efforts to reduce emissions at its Pacific bauxite, alumina and aluminium operations.


“The construction of the Amrun solar farm and battery storage system, which is located on Wik and Wik-Waya Traditional lands, is an important milestone for Weipa operations and will contribute to Rio Tinto’s commitment to reduce operational greenhouse gas emissions,” Rio Tinto Weipa operations general manager Shona Markham said.


“The Amrun solar farm will be one of three Weipa operations solar stations, which will together provide 18MW of solar generation capacity to our mines and the Weipa town.


“This project helps us make inroads towards our ambitions to reduce greenhouse gas emissions from our operations.”


The project is expected to reduce Amrun’s diesel electricity consumption by 37 per cent and annual CO2-equivalent emissions by 14,000 tonnes.


Aggreko has been contracted to build, own and operate the solar farm to supply renewable electricity to the mine operations, in addition to its current contract to supply electricity generated from an existing diesel power station.


“Aggreko is excited to be supporting Rio Tinto on working towards meeting their decarbonisation goals and our own with this project,” Aggreko Asia Pacific managing director George Whyte said.


“This partnership aligns with our mission to accelerate the energy transition and as a world leader in the supply of clean energy infrastructure, we are confident that we will successfully deliver reliable and efficient energy for Rio Tinto’s Amrun operations.”


Early works have begun on the new solar farm, which is expected to be operational by early 2025.



Once completed, the Amrun solar farm will provide about 21 gigawatt hours of renewable power annually.

The Queensland Government has broken ground on the first construction works of the $5 billion CopperString project. Work commenced yesterday on the CopperString projects’ first and largest workforce accommodation site. The site will house those charged with building the project’s 840km high-voltage transmission line that will connect Mount Isa to the ‘SuperGrid’ for the first time. The workforce accommodation will house up to 550 construction workers at its peak. These workers will construct a nearby substation and progress early stages of the transmission line development heading west from Hughenden out to Mount Isa. Supercharging the state’s north-west aims to unlock Queensland’s $500 billion north-west minerals province. It’s expected CopperString will be complete in 2029, weather and construction conditions permitting. Queensland Premier Stephen Miles said CopperString is the biggest ever expansion to the state’s publicly owned energy system. “Queenslanders deserve cheaper, cleaner, more reliable energy – to power their homes, our schools, hospitals, shopping centres and more,” Miles said . “CopperString will be the catalyst for transforming Queensland’s north and north-west – opening up mining opportunities, creating more jobs and unlocking critical minerals which will be essential in developing renewable technologies. “This is the start of a long and exciting future for the region and our state.” Commencing later this month, project owner, Queensland Powerlink, will be offering free sessions for businesses along the CopperString corridor to build their capabilities. The program includes five workshops and one-on-one assistance to help businesses build confidence to bid on major projects and supply chain work in the region. “All of North Queensland understands the immense opportunities that CopperString presents for local jobs both directly and indirectly which is why this is such a momentous day,” Resources and Critical Minerals Minister Scott Stewart said.  “Critical minerals are the next big boom for the resources industry and the feedback I’ve had from companies is that this project is key to unlocking those opportunities.” Source: https://www.australianmining.com.au/queensland-breaks-ground-on-copperstring/

Underground mines are busy places, and it’s vital companies are on top of their processes to enable an efficient and safe underground operation. Whether it’s having the best equipment to drive higher production, maximise return on investment, minimise waste or keep workers out of harm’s way, mining companies benefit from understanding and investing in the right underground technologies.

BHP has started environmental processing to have the transport at its Escondida copper mine in Chile transitioned to an electric trolley system. The Big Australian will invest around $US250 million ($371.6 million) in the project at Escondida, which it owns in a joint venture with Rio Tinto. The funds will go towards installing key infrastructure to electrically assist the movement of extraction trucks in areas where the highest fuel consumption currently takes place. BHP has submitted an environmental impact statement to the Environmental Impact Assessment System in Chile. “The electric trolley system is one of the initiatives with which we seek to move towards a safer and more sustainable way of operating hand in hand with technology,” BHP Escondida president Alejandro Tapia said . “This project will allow us to reduce the fuel consumption of our extraction trucks and thus advance our goal of net-zero operational greenhouse gas emissions by 2050.” The project includes the construction of a new electrical substation and transmission lines both inside and around the Escondida Norte pit. These facilities will electrically assist the movement of trucks inside the mine in the areas where they go up loaded with ore and, consequently, consume more fuel. With this new technology, instead of using diesel, they will be propelled by electrical power, reducing greenhouse gas emissions and improving productivity associated with truck performance given the higher travel speed. Once construction kicks off up to 160 jobs are expected to be created. The trolley project is in addition to other technological transformation initiatives that the company maintains in different stages of study and execution, including the progressive incorporation of autonomy in its mining equipment.  To date, Escondida has six autonomous trucks in full operation and by 2025 it expects to have the largest fleet of autonomous equipment in South America.
