Decarbonisation in mining: building resilience through tailored execution approaches

Many renewable energy projects, particularly solar farms, are being developed in coastal regions due to their high solar potential. However, these areas, including the Pilbara in Western Australia – home to some of the world’s largest mining operations – are also vulnerable to extreme winds and cyclonic conditions. According to Australian standards (AS/NZS 1170.2:2021), Category D cyclones in this region can generate wind speeds of up to 288 km/h, necessitating energy infrastructure to be designed for exceptional resilience.

A recent example from our GHD team is the Port Hedland Solar and BESS project. Given the region's frequent cyclonic activity, we’ve provided invaluable support in navigating these challenges. Our team has integrated the specific design and engineering considerations required for solar farms and BESS installations in the Pilbara, including technical representation in engaging with technology providers. This expertise is critical in ensuring that renewable energy infrastructure remains resilient under extreme conditions. The recent passage of Cyclone Zelia east of Port Hedland served as a stark reminder of the importance of designing renewable energy solutions capable of withstanding nature’s extremes. 

As the energy landscape evolves, so too does the way mining companies approach energy projects. Traditionally, these projects were delivered through Power Purchase Agreements (PPAs), with energy companies managing design, construction, and operation, while mining companies acted as energy offtakers. However, as miners take a more active role in decarbonisation – particularly in reducing Scope 2 emissions – many are now developing and managing their own renewable energy projects.

By taking ownership, mining companies gain greater control over quality, ensuring their energy systems meet high structural, electrical, and safety standards. This shift enables them to apply the same precision and attention to detail they use in mining operations. However, assuming direct responsibility for energy infrastructure introduces new set of obstacles that must be addressed. 

One of the key challenges mining companies face when managing their own renewable projects is the shortage of professionals with the right qualifications. Unlike the PPA model, where this aspect is managed by developers, with miners driving these projects now the situation has changed.

The limited pool of skilled workers, especially in remote regions like the Pilbara, has intensified competition for talent, leading to project delays and rising costs. With multiple renewable energy projects underway simultaneously, securing the right expertise has become a strategic priority. The key question remains: who is willing to pay the premium to attract and retain top professionals, and how can companies mitigate these risks effectively? 

As mining companies accelerate their decarbonisation efforts, the success of renewable energy deployment will depend on a proactive approach to managing risks, controlling costs, and ensuring seamless coordination across multiple streams.

The path to decarbonisation isn’t just about adopting new technologies – it’s about delivering the right projects, the right way, at the right time. By adopting a comprehensive, "big picture" lens and tailoring execution strategies to the context, the mining industry can pave the way for a cleaner, more sustainable future. Our GHD team is proud to have had the pleasure of contributing to this journey, providing comprehensive guidance throughout the lifecycle of their large-scale energy initiatives – from initiation to execution.
