Aggreko strikes gold at Porphyry

Kalgoorlie, Australia – Energy solutions company Aggreko, world leader in the supply of modular power, has completed construction and commissioning of a new 4.4MW solar farm utilising 5B Maverick PV panels, as well as two Aggreko Y.Cube battery energy storage systems (totalling to 2MW/1MWh) which will supply renewable power to Northern Star Resources’ Porphyry gold mine under a long term power purchase agreement. The Porphyry Project is part of Northern Star Resources’ Carosue Dam Operations.

The existing 5MW diesel power station – owned and operated by Aggreko – has been connected and integrated with the new solar farm and BESS to create Aggreko’s second thermal renewable hybrid power station in WA.

“The new solar array was commissioned in February 2024 and is set to produce about 7.4GWh of renewable energy each year – saving 1.67 million litres of diesel fuel and 4,486 metric tonnes of CO2e emissions annually,” Aggreko Managing Director Asia Pacific, George Whyte said.

“We worked closely with 5B to supply a relocatable solar plant, which seamlessly integrates renewables with conventional power sources. This ensures a reliable and sustainable energy supply, while optimising cost effectiveness.”

Aggreko’s ESG strategy is underpinned by two goals:
• Net zero emissions from facilities and operations by 2035
• 30% reduction in the emissions intensity of energy solutions by 2030
These environmental commitments sit alongside the company’s social and governance commitments: investing in its own skills and communities and being an ethical and transparent business.

Northern Star Resources’ Carosue Dam Operations General Manager, John Albrecht, said the solar PV power will help boost the operation’s financial and environmental footprint.

“The off-grid power solution implemented provides a reliable, and cost-effective solution that can be scaled up and down as needed throughout our mine’s operational life cycle.”
