A new solar farm in the Northern Goldfields of Western Australia has been switched online thanks to a collaboration between BHP and renewable energy provider TransAlta, which, BHP says, will reduce Scope 2 emissions at the Nickel West northern operations by 12%.

The Northern Goldfields Solar and Battery Storage Facility is one of the world’s largest off-grid mining solar and battery energy storage systems and features about 70,000 solar panels across 90 ha of land.

The initiative, which will replace power currently generated from diesel and gas, will be a significant step towards BHP’s aim to decarbonise its operations by 30% by the 2030 financial year.

It includes a 27.4 MW solar farm at Mt Keith, and a 10.7 MW solar farm and 10.1 MW battery at Leinster, which is integrated into TransAlta’s Northern Goldfields remote power grid.

Construction on the facility began in 2022, creating more than 100 direct and indirect jobs in the Goldfields and Perth regions, and will support ongoing employment during operations.

BHP Australia President, Geraldine Slattery, said: “Renewables are increasingly powering BHP operations around the globe and this facility – the first we have built on one of our sites – is another step forward in our plans to reduce our operational greenhouse gas emissions by at least 30% by FY30, from FY20 levels.

“Nickel is in high demand for batteries and electric vehicles, and this progress is part of our commitment to delivering more sustainable, lower carbon product to our customers.”

BHP Nickel West Asset President, Jessica Farrell, said the initiative was one of many ways Nickel West was reducing its operational emissions – it was also considering wind farms in the northern and southern Goldfields.

“It’s fantastic to see the Northern Goldfields Solar and Battery Storage Facility switched on,” she said. “It’s on the back of a team of dedicated engineers, technicians and many others bringing new ideas to the table to support the development and integration of reliable and affordable renewable power to our business.

“The initiative will help Nickel West reduce Scope 2 greenhouse gas emissions at our northern operations by 12%. This will result in an estimated reduction of 54,000 t of CO2-e per annum – the equivalent of removing 23,000 combustion engine cars2 from the road each year.”

TransAlta’s President and Chief Executive Officer, John Kousinioris, said the company was excited to flick the switch on what was a ground-breaking project for the organisation.

He said: “We are excited to work together with BHP to realise this innovative solution to meet BHP’s renewable electricity needs. This facility represents a first for both companies – it’s BHP’s first on-site, large-scale renewable project globally, and it’s TransAlta’s first renewable energy facility in Australia. It’s also the first time we have combined solar and battery storage to offer a hybrid solution.

“This unique project enabled us to apply the extensive capability and technical knowledge we have to the development of a large-scale facility in a remote part of Western Australia.

“Working under our longstanding relationship with BHP, we were able to collectively solve challenges and break new ground at the same time as playing a part in WA’s exciting and rapidly accelerating transition to a cleaner energy future.”

Construction is now underway on one of the world’s largest off-grid mining solar and battery energy storage systems being built by TransAlta to help power BHP Nickel West’s Mt Keith and Leinster operations.

The Northern Goldfields Solar Project, which was announced last year, includes a 27.4 MW solar farm at Mt Keith, a 10.7 MW solar farm and a 10.1 MW battery at Leinster, and will be integrated into TransAlta’s Northern Goldfields remote power grid.

The project, which will replace power currently supplied by diesel and gas, will help BHP Nickel West reduce Scope 2 emissions at its Mt Keith and Leinster operations by 12%, resulting in an estimated reduction of 54,000 t/y of CO2-e.

The construction phase of the project is set to create more than 100 direct and indirect jobs in the Goldfields and Perth regions, and is expected to produce its first solar power by November 2022.

The project aims to employ Traditional Owners from the Tijwarl Native Title Holders following TransAlta’s contractor, juwi, awarding Cundaline Resources with the primary civil contractor role on the project. Cundaline Resources is an Aboriginal business whose owners include members of the Tjiwarl Aboriginal Corporation.

BHP Nickel West Asset President, Jessica Farrell, said BHP was meeting its commitment to deliver sustainable low carbon nickel to its customers, a product that is in high demand to power batteries and electric vehicles.

“The Northern Goldfields Solar Project is BHP’s first off-grid large-scale renewable energy project across our global operations and, significantly, will remove the equivalent of up to 23,000 combustion engine cars from the road every year, supporting our greenhouse gas reduction targets,” Farrell said.

“It is also very exciting that following years of close engagement with the Tjiwarl Native Title Holders, our project has contracted the services of a local Aboriginal business, boosting opportunities for people in the local community and across the northern Goldfields generally.”

TransAlta also unveiled today it had entered into an agreement with BHP to identify potential wind sites for a 40-50 MW wind farm, which would connect to TransAlta’s northern grid and reduce Scope 2 emissions at BHP’s Mt Keith and Leinster operations by an estimated further 30 per cent.

Adding wind will increase renewable energy supply to support BHP’s growth and to further each company’s sustainability goals, BHP said.

TransAlta Australia Managing Director, Kelvin Koay, said the construction phase of the solar and battery farm was an exciting step for the project.

“The Northern Goldfields Solar Project is TransAlta’s first renewable energy project in Australia and is an important element of our Clean Electricity Growth plan. This project contributes to achieving TransAlta’s target of a 75% GHG emissions reduction over 2015 levels by 2026 and 2050 carbon neutrality goal. As a company, we have a strong decarbonisation track record having already achieved a 61% emissions reduction since 2005.

“We’ve had a long-standing partnership with BHP since the 1990s and we welcome the opportunity to support BHP in meeting its carbon emission targets and in enhancing its competitiveness as one of the lowest carbon nickel miners in the world.”

BHP and its power partner in the Goldfields of Western Australia, TransAlta, are to build two solar farms and a battery storage system to help power the Mt Keith and Leinster nickel operations.

This will help BHP reduce emissions from electricity use at Mt Keith and Leinster by 12%, based on financial year 2020 levels.

The Northern Goldfields Solar Project will include a 27.4 MW solar farm at Mt Keith and a 10.7 MW solar farm and 10.1 MW battery at Leinster, and will displace power currently supplied by diesel and gas turbine generation, BHP said.

This will result in an estimated reduction of 540,000 t of CO2e over the first 10 years of operation. This is the equivalent of removing up to 23,000 combustion engine cars from the road every year, according to BHP.

BHP commissioned the solar farms and battery to be built, owned, and operated by TransAlta as part of the Power Purchase Agreement (PPA) extension signed in October 2020. Construction will commence in the December quarter, is expected to take 12-14 months and, at its peak, will employ over 100 people on site.

BHP Nickel West, Asset President, Eddy Haegel, said: “This is the first large-scale onsite solar farm and battery that BHP has commissioned at any of its global operations.

“The Northern Goldfields Solar Project will further improve our position as one of the lowest carbon nickel miners in the world. It will reduce emissions from electricity use at Mt Keith and Leinster by 12%, reduce fuel costs and improve the reliability of our electricity supply with the addition of the battery storage system.

“This announcement follows the nickel supply agreement we signed with Tesla last week. Sustainable low carbon nickel is essential for our battery and electric vehicle customers.”

TransAlta Corporation President and Chief Executive Officer, John Kousinioris, said: “We are proud to be supporting BHP’s emissions reduction targets and sustainability goals through the expansion of our renewable generation footprint into Australia.”

The partnership will contribute to BHP’s medium-term target to reduce Scope 1 and 2 emissions from our operated assets by at least 30% from financial year 2020 levels by its 2030 financial year.

The project is subject to final Western Australia state government approvals.
