Calidus to incorporate solar power, battery storage into Warrawoona power mix

Calidus Resources has executed an agreement with Zenith Pacific for the construction of a 4 MW solar farm with 3.5 MW battery energy storage system at its Warrawoona gold project in Western Australia.

Zenith is currently constructing the 11 MW gas-fired power station at Warrawoona under a Power Purchase Agreement (PPA). The construction of the solar farm is part of the PPA whereby Calidus purchases power from Zenith.

The solar farm will be constructed in the second half of 2022 and will feed into the distribution line between the power station and accommodation village.

Calidus Managing Director, Dave Reeves, said the decision to proceed with the solar farm and battery storage was in line with the company’s environmental, social and governance (ESG) initiatives.

“Calidus is committed to carbon reduction as part of its ESG policy,” he said. “This renewable microgrid is a cornerstone to our carbon reduction plan which includes the use of LNG, not diesel, and the ability of the LNG gensets to use up to 25% hydrogen.

“We are pleased to extend the relationship with Zenith to incorporate this renewables project, and look forward to its construction in the second half of this year.”

Calidus plans to start mining at Warrawoona in the June quarter of this year, and is forecast to initially produce 105,000 oz/y of gold.

Iluka taps into hybrid power at Jacinth-Ambrosia after KPS project completion

Pacific Energy says its subsidiary, KPS Power Generation, has completed the conversion of Iluka Resources’ 10 MW diesel power station at the Jacinth-Ambrosia mineral sands mine in South Australia to a hybrid power facility.

The “world first” hybrid power station incorporates both solar photovoltaics and electric turbo compounding (ETC) technology, combined with an upgraded control system, Pacific Energy said. ETC technology allows generators to maintain the same power output using less fuel and producing lower CO2 emissions, making generators work more cleanly and effectively by recovering waste energy.

The reduction in diesel consumption and improvement in fuel efficiency is expected to save over 2 million litres of diesel and over 5,500 t/y of CO2 at the operation, according to Pacific Energy.

KPS has operated the 10 MW diesel power station at the Jacinth-Ambrosia site since 2009. Under the new contract, which runs for an initial term of seven years, KPS will:

  • Install 3.5 MW of solar power generation;
  • Integrate the solar array with the diesel power station; and
  • Introduce ETC technology to each of the 10 1 MW generators.

juwi Renewable Energy Pty Ltd, the Brisbane-based subsidiary of juwi AG, constructed the medium penetration solar/diesel hybrid power solution for Jacinth-Ambrosia, with KPS owning and operating the hybrid project. It is expected to deliver almost 21% of the mine site’s annual electricity needs.

Shane Tilka, General Manager, Australian Operations at Iluka, said: “The move from diesel to hybrid energy at Jacinth-Ambrosia marks an important evolution in Iluka’s Australian operations. It also offers a potential blueprint for the future use of renewable energy at the company’s other existing and planned operations.”

Pacific Energy Group CEO, Jamie Cullen, said: “We are thrilled to work alongside Iluka, a valued long-term client to deliver a world-class, world-first solar PV and ETC hybrid power facility, and to assist them with reducing carbon emissions and transitioning to net-zero emissions.”

Glencore’s Mount Isa ops set for renewable power injection from APA Group

APA Group has reached a Final Investment Decision (FID) to build stage two of the Mica Creek Solar Farm in Mount Isa, Queensland, a decision that has brought with it an agreement to supply Glencore’s Mount Isa Mines copper-lead-zinc-silver operations in the state with renewable electricity.

The stage two investment is underpinned by a variation to the existing offtake agreement with APA customer Mount Isa Mines Limited (MIM), a Glencore company, according to APA. The variation adds a new service for the supply of electricity from the Mica Creek Solar Farm for 15 years, requiring additional capital expenditure by APA of around A$70 million ($49.8 million).

FID on stage two, which comprises 44 MW of additional solar power generation, follows APA’s announcement on November 1 that APA had reached FID on stage one of the Mica Creek Solar Farm and entered into an offtake agreement with MMG’s Dugald River operation to supply an initial 44 MW of renewable electricity to the miner. APA’s total investment for both stages of the works is estimated to be around A$150 million.

The second stage of the solar farm is to be co-located on the same site as stage one, near APA’s Diamantina Power Station Complex, on land which is leased from the Queensland Government. The solar farm is expected to be operational by mid-2023.

APA’s solar offtake agreement has been negotiated at a commercially competitive tariff, consistent with utility solar pricing, and will reduce the average delivered cost of power for MIM, APA said.

“This A$150 million investment will support APA’s vision for a world-leading hybrid energy grid in Mount Isa and our aspiration to support the further increases of renewable energy penetration for the region,” APA CEO and Managing Director, Rob Wheals, said.

“The support for the 88 MW Mica Creek Solar Farm demonstrates the enthusiasm of customers in the Mount Isa region for integrated energy solutions that can both meet their energy needs and help reduce their operational emissions.

“With continued strong interest from customers, APA is investigating a potential expansion for a third stage.”

Rio Tinto breaks ground on solar, wind power project at QMM in Madagascar

In accordance with the commitments made last July, Rio Tinto QIT Madagascar Minerals (QMM) and its partner, CrossBoundary Energy (CBE), have laid the foundation stone for the solar and wind power plant project that will supply the QMM ilmenite mine operations in Fort Dauphin, southern Madagascar.

The ceremony took place in the Ehoala Park area, in the presence of high dignitaries, including the Minister of Energy and Hydrocarbons, the Minister of Environment, the mayor of Fort-Dauphin and the Governor of the Anosy Region. The renewable energy project will go some way to helping operations in Madagascar reach carbon neutral status by 2023.

The renewable energy plant will be built and operated by CBE, an independent power producer with whom QMM has signed a 20-year power purchase agreement. The first unit, an 8 MW solar energy facility, will be operational in 2022. The 12 MW wind power facility will be completed in 2023. The project also includes an 8.25 MW lithium-ion battery energy storage system.

Around 18,000 solar panels and four wind turbines will enable QMM to meet all of its electricity needs during peak periods and up to 60% of its annual electricity consumption, as well as to reduce its annual carbon dioxide emissions by about 26,000 t, Rio said. In addition, the renewable power supply will reduce QMM’s heavy fuel oil purchases by up to 8,500 t/y. With this plant, QMM will also replace the majority of the electricity it currently supplies to the town of Fort-Dauphin and its 80,000 community members with clean energy.

Ny Fanja Rakotomalala, President of QMM, said: “This project is a key component of our ‘sustainable mine’ initiative, which aims to leave a lasting legacy for present and future generations, built independently of our mining operations. We want to leave this legacy through permanent dialogue, the full integration of activities within the development plan of the region, responsible social and environmental governance, the reduction of our environmental footprint and therefore of our carbon footprint, and through the creation of economic and social opportunities increasingly independent of QMM.

“This project is a strategic test, not only in Madagascar but also in the mining industry as a whole, as we have to innovate and rethink our operations in order to combat climate change and leave a sustainable legacy.”

Matt Tilleard, Managing Partner of CBE, said: “By establishing a commercial power plant that blends solar photovoltaic, battery energy storage and wind power, the QMM project greatly improves the island of Madagascar standing as a regional renewable energy leader. CBE is pleased to take up this technical challenge. We believe large-scale, complex commercial energy projects can be realised here in Madagascar thanks to ample supply of renewable resources, holistic government support and knowledgeable local implementing partners.”

Fortescue’s Chichester Hub iron ore operations hit solar power milestone

Fortescue Metals Group’s Chichester Hub operations are now being powered by solar energy following the completion of the 60 MW Alinta Energy Chichester Solar Gas Hybrid Project in Western Australia’s Pilbara region, the miner confirmed.

Completion of the project with Alinta Energy marks a major milestone in the delivery of Fortescue’s decarbonisation strategy, as the company works towards its ambitious target of being carbon neutral by 2030 for Scope 1 and 2 emissions.

The solar farm will power up to 100% of daytime operations at Fortescue’s Christmas Creek and Cloudbreak iron ore sites, displacing around 100 million litres of diesel every year. The remaining power requirements will be met through battery storage and gas generation at Alinta Energy’s Newman Power Station, FMG said.

Fortescue Chief Executive Officer, Elizabeth Gaines said: “The completion of this project is a practical example of Fortescue delivering on its ambitious carbon neutrality target and demonstrates that renewables can power the energy needs of Australia’s mining and resources sector.

“As Fortescue transitions from a pure-play iron ore producer to a green energy and resources company, this milestone is a critical part of our Pilbara Energy Connect project which, together with the Chichester solar farm, will see 25% of Fortescue’s stationary energy powered by solar.”

Alinta Energy’s MD & CEO, Jeff Dimery, said: “Together, we’ve built a benchmark renewable project with an ambitious partner and, given the abundance of high quality renewables resources in the Pilbara, we look forward to supporting others to do the same.

“I’m very proud of the team and thank Fortescue, our partners, contractors and suppliers, NAIF, ARENA, and, in particular the Nyiyaparli People, on whose country the solar farm sits.”

The project also includes the construction of approximately 60 km of new transmission lines, linking Fortescue’s Christmas Creek and Cloudbreak mines to the solar farm and Alinta Energy’s existing energy generation infrastructure in Newman.

Green is good: playing to win in a multi-trillion-dollar green-tech game

The COP26 Glasgow Climate Summit has made it clear the Australian Government will largely rely on private and listed companies adopting new green technologies to hit net-zero by 2050, according to the organisers of IMARC.

Nowhere will this be more apparent than in Australia’s booming resources sector, and in perhaps no other sector is there so much investment upside, they say. COP26 leaders flagged eye-watering multi-trillion-dollar investment figures that will become available in the race to net zero, in addition to the more than one third of worldwide institutional investment that now requires an ESG component.

Mid-to-large cap companies that are not on-board, or above-board, with the ‘greening’ of their operations through technology will not only damage their reputations but miss out on an entire new generation of value-creation opportunities, according to the organisers.

Green technology comes in all shapes and sizes, as do the multiple challenges posed by phasing out fossil fuels. Advancing Australia to net zero will require a mix of technological advances, infrastructure upgrades and strong governance.

For the companies participating in Australia’s biggest mining conference, the International Mining and Resources Conference (IMARC) in 2022, early adoption of green technology is essential to creating value.

Net zero: the next big thing?

With about 200 nations signing on, the consensus of the Glasgow pact was clear – there is much for companies to gain by acting now, and everything to lose by sitting on their hands.

A ‘wall of new private sector money’ will be available to those companies that embrace green technology and clean up their operations, according to IMARC organisers.

This multi-trillion-dollar wall of new money does not include the soaring price of battery metals, and Australia’s position as one of the biggest beneficiaries of the green tech uptake.

According to the Resources and Energy Quarterly September 2021, Australia is the world’s largest exporter of lithium, the second largest producer of copper and produces more than one-quarter of the world’s nickel.

Schneider Electric President of Mining Minerals and Metals, Rob Moffit, said solar and wind generation were being rapidly adopted, but battery storage technology needs to improve so that uptake can continue to grow.

“As you generate more power, you need to find better and more efficient ways to store that power,” he said. “In line with that, there is going to be further investments into battery technologies, particularly the composition of batteries.

“Demand for artificial intelligence (AI) is also set to rise. As we combine multiple energy sources, it starts to become a complex system that needs to be managed. AI and machine learning are the best technologies to do this.”

Kirkland Lake Gold’s Senior Vice President, John Landmark, echoed the sentiments of Moffit and insisted that truly renewable, reliable infrastructure was vital to the transition.

“Power utility companies are the biggest hurdle to greening our industry,” he said. “Resource companies can only do so much in reducing their footprint, but clean and affordable energy is the biggest hurdle which lies outside of the hands of the resources company that needs to be cleaner.

“Having a ‘token’ windmill or solar panel looks great in a photo-op but doesn’t address the sustainable operation and use of such renewable energy.”

‘Greenwashing’: the elephant in the room

There is perhaps no greater threat to the ESG bona fides of a mining and resources company than ‘greenwashing’.

Greenwashing is the practice of misleading the media or the general public, or of taking advantage of a lack of awareness of what constitutes a legitimately ‘green’ or ‘clean’ technology, fuel or practice, the organisers said.

And it is firmly under the scrutiny of the public eye.

Most recently, the High Court of Australia refused to hear Volkswagens’ appeal against its A$125 million ($89 million) ‘Dieselgate’ fine – the largest penalty ever imposed on a company for misleading consumers – for deliberately deceiving regulators and customers about the environmental performance of its cars.

Landmark said greenwashing was a particularly problematic issue because a company that damages its own reputation often leads to other companies within an industry being tarnished with the same brush.

He said there is also a tendency in industry to satisfy public demand and ESG agency requirements, rather than focus on legitimate sustainable practices, “which fosters an environment where resource companies feel like they need to address these tick boxes, leaving companies to dilute their sustainability efforts on non-material issues or embellish on them”.

He added: “By Kirkland Lake Gold sticking to facts only and not elaborating extensively on our sustainability achievements, we aim to ensure our credibility is linked to true data.”

Moffit emphasised this notion, saying it was vital for companies to avoid the greenwashing trap.

“[It] can be achieved by having the right processes in place — specifically using scientifically-based, externally-audited, transparent and consistent protocols,” he said. “It is vital that all commitments are certified by science and must cover all emissions scope categories, not only the ones directly related to the company’s operations.”

Electricity or hydrogen?

Electric- and hydrogen-powered vehicles are often seen as competing technologies. However, mining operations are complicated beasts and, due to the size, location and technique – open pit or underground – of the operation, certain technologies will be better suited than others, according to the event organisers.

Landmark said having many viable options available was the best way to ensure greater uptake of new vehicle technologies and therefore a greener economy, but pointed out that it is, “crucial that both electric and hydrogen vehicles are powered by a green grid”.

Moffit said the most significant benefit of hydrogen technology in heavy industry and transportation is hydrogen’s superior energy density.

“Electric and hydrogen are complementary vehicle technologies,” he said. “Electrification is perfectly suited towards passenger vehicles, but it currently isn’t the ideal option for heavy-duty vehicles such as haul trucks due to the energy density of a battery, which is just 1%. This means that for a 40-t truck, just over four tonnes of lithium-ion battery cells are needed for a range of 800 km. This is not viable.”

Landmark and Moffit will be sharing further insights on green technology at the upcoming IMARC in Melbourne, Australia, on January 31-February 2, 2022.

APA Group to deliver solar power to MMG’s Dugald River mine

Stage one of APA Group’s plan to build an 88 MW solar farm in Mount Isa, Queensland, Australia, has got underway with a Final Investment Decision to construct 44 MW of capacity to serve MMG’s Dugald River zinc-lead mine in the state.

The investment of more than A$80 million ($60 million) will see APA Group provide solar power to the mine as part of a 15-year offtake agreement.

APA also entered into a 32-year lease agreement with the Queensland Government to locate the solar farm on a site near APA’s Diamantina Power Station Complex. The first stage of the solar farm is expected to be operational by the March quarter of 2023, while APA says it is in advanced discussions with a number of customers to commit to the development of stage two, reaching 88 MW.

APA CEO and Managing Director, Rob Wheals, said the Mica Creek Solar Farm will deliver lower emissions power underpinned by the reliability of APA’s gas-fired power, while reducing the average cost and emissions of power across Mount Isa.

MMG, meanwhile, said the solar agreement will supply Dugald River with renewable energy to reduce its carbon footprint and provide immediate energy cost savings once operational in early 2023.

“The new agreement further supports MMG’s commitment to supporting the global transition to a low carbon economy with the company’s key products, copper and zinc, playing a critical role in the development of sustainable technologies such as solar panels, wind turbines, electric vehicles and batteries,” it added.

Rio Tinto backs accelerated Scope 1 and 2 carbon emission cuts with $7.5 billion of investments

Rio Tinto has outlined a new target to reduce its Scope 1 and 2 carbon emissions by 50% by 2030, more than tripling its previous target. To achieve this, it is setting aside around $7.5 billion of direct investments between 2022 and 2030.

Unveiled during an investor seminar this week, Rio said a 15% reduction in emissions is now targeted for 2025, five years earlier than previously stated, relative to its 2018 baseline of 32.6 Mt (CO2 equivalent – equity basis).

In recognition of the broader carbon footprint of the commodities it produces, Rio says it will accelerate its investment in R&D and development of technologies that enable its customers to decarbonise. Working in partnership with governments, suppliers, customers, academia and others, Rio intends to continue to develop technologies like ELYSIS™ for carbon-free aluminium and multiple pathways to produce green steel.

To meet additional demand created by the global drive to net zero emissions, Rio Tinto will prioritise growth capital in commodities vital for this transition with an ambition to double growth capital expenditure to about $3 billion a year from 2023, it said.

Rio Tinto can decarbonise, pursue growth and continue to deliver attractive returns to shareholders due to its strong balance sheet, world-class assets and focus on capital discipline, it explained.

Some key points from the presentation include:

  • Decarbonisation of the Pilbara will be accelerated by targeting the rapid deployment of 1 GW of wind and solar power. This would abate around 1 Mt of CO2, replace natural gas power for plant and infrastructure and support early electrification of mining equipment;
  • Full electrification of the Pilbara system, including all trucks, mobile equipment and rail operations, will require further gigawatt-scale renewable deployment and advances in fleet technologies
  • Options to provide a greener steelmaking pathway for Pilbara iron ore are being investigated, including with biomass and hydrogen;
  • Options are progressing to switch the Boyne Island and Tomago smelters in Australia to renewable energy, which will require an estimated circa-5 GW (equity basis) of solar and wind power, along with a robust “firming solution”;
  • Development of ELYSIS to eliminate carbon emissions from the smelting process is progressing, with commercial scale technology on track for 2024.

Pilbara Minerals enlists Contract Power Australia for Pilgangoora solar power plans

Pilbara Minerals Limited has announced a Power Purchase Agreement (PPA) between its wholly owned subsidiary, Pilgangoora Operations Pty Ltd, and Contract Power Australia that could see a 6 MW solar array built at the Pilgangoora lithium project in Western Australia.

The solar array is, the company says, an important demonstration of its commitment to implementing environmentally friendly power solutions, as a part of its pledge to transition to net-zero emissions (scope 1 and 2) in the decade commencing 2040.

Pilbara Minerals said it looks forward to continuing its working relationship with Contract Power and the broader Pacific Energy Group, which began in 2018 when the first baseload power station was installed at Pilgangoora. The PPA involves a 15-year contract to construct, operate and maintain a 6 MW solar array, which is estimated to displace 3.8 million litres/y of diesel fuel, saving an estimated 9,900 t of CO2/y over the contract period.

“A key factor in awarding this exciting new renewable energy project to Contract Power was their established track record and ability to design and safely deliver turnkey energy projects,” the company added.

It is anticipated that procurement for the project will commence imminently with commissioning expected in late July 2022, and commercial operation from the end of August 2022. The design facilitates the future expansion of solar capacity and potential inclusion of battery storage at Pilgangoora, as Pilbara Minerals creates further efficiencies around its power supply and storage solutions at Pilgangoora, it said.

The installation of the first phase of the solar farm is just one part of the initial rationalisation of power assets at Pilgangoora, as the company further integrates the Ngungaju Operation. A local power network will be created to join the Ngungaju and Pilgan Plants, and the Carlindi camp facilities thereby creating further efficiencies, Pilbara Minerals explained.

Pilbara Minerals’ longer-term objectives include integration with other northern Pilbara power and/or gas and renewables sources with a view to creating further efficiency gains on the path to net-zero carbon.

BHP closes in on renewable energy supply for Olympic Dam mine

BHP says it expects to shortly enter into renewable energy supply arrangements to enable the Olympic Dam mine in South Australia to reduce its emission position to zero for 50% of its electricity consumption by 2025, based on current forecast demand.

The arrangements will be supplied by Iberdrola, including from the Port Augusta Renewable Energy Park in South Australia, which is expected to be Australia’s largest solar-wind hybrid plant once in operation in July 2022.

BHP is to become the primary customer of this new renewable facility, with the renewable energy supply arrangements referred to including a retail agreement with Origin Energy, who will facilitate the arrangements.

This announcement follows BHP’s entry into renewable energy agreements for BHP’s operations in Western Australia in 2021, Queensland in 2020 and in Chile in 2019.

BHP Olympic Dam Asset President, Jennifer Purdie, said: “These arrangements will support an exciting new renewable energy project which will contribute to South Australia’s renewable energy ambitions.

“Olympic Dam’s copper has an important role to play to support global decarbonisation and the energy transition as an essential product in electric vehicles and renewable infrastructure. Reducing emissions from our operations will further enhance our position as a sustainable copper producer.”

Iberdrola Australia Chief Executive Officer and Managing Director, Ross Rolfe, said: “We are delighted to be partnering with BHP, helping them meet their decarbonisation and sustainability objectives. We worked very closely with BHP to design these bespoke renewable energy supply arrangements. Olympic Dam is to be the primary customer for the Port Augusta Renewable Energy Park, a demonstration of their commitment to local procurement and sustainable economic development.”

The arrangements, intended to commence on July 1, 2022, are one of the actions BHP is taking to contribute to its medium-term target to reduce operational greenhouse gas emissions (Scope 1 and 2) from its operated assets by at least 30% from financial year 2020 levels by financial year 2030.
