Coal-Fired Revival: The Data Centre Opportunity
EnergyAustralia’s plan to repurpose its coal-fired power plants as sites for new data centres has sparked debate about Australia’s energy future. This may seem like an unusual pairing – coal-fired power plants, notorious for their environmental impact, are being touted as ideal locations for the energy-hungry behemoths that are data centres.
EnergyAustralia’s chief executive, Mark Collette, points out that coal-fired sites offer access to water, around-the-clock electricity, and a skilled workforce. This could speed up construction of new facilities, which can take years or even decades from scratch.
However, this opportunity raises pressing questions about Australia’s long-term energy mix. The nation is already grappling with the impact of data centres on its power grid. With 165 operating facilities consuming a significant chunk of electricity demand on the eastern seaboard, plans to build dozens more have sparked community pushback and concerns about strain on resources.
Data centre usage could rise nearly seven-fold by 2035, according to the Australian Energy Market Operator. Securing access to renewable energy sources and land is crucial for these projects. The recent agreement between state and federal energy ministers to develop national standards requiring data centres to source 100% of their electricity from renewables is a welcome step towards addressing this issue.
EnergyAustralia’s proposal highlights the complex interplay between different energy sources in Australia’s mix. As Santos’ managing director Kevin Gallagher noted, the world has not abandoned fossil fuels in favour of renewable energy – instead, it’s taking more of everything. This underscores the need for a nuanced approach to our energy policy, one that acknowledges the complementary role of different sources.
The repurposing of coal-fired power plants as data centre sites raises questions about the future of these facilities and their employees. EnergyAustralia is actively planning for what comes next at Yallourn, with plans to create a new energy security precinct featuring solar power, back-up gas power, and battery storage.
Amidst all this talk of data centres and coal-fired plants, it’s worth considering the bigger picture. The government’s welcoming attitude towards large investments in Australian data centres is telling, particularly at a time when the economy is experiencing sluggish growth. This highlights the tension between economic interests and environmental concerns that we’re seeing play out across various sectors.
The future of Australia’s energy mix remains uncertain, but one thing is clear: it won’t be built on coal alone. As EnergyAustralia moves forward with its plans to repurpose its coal-fired power plants as data centre sites, the industry must address the pressing question of how these massive facilities will meet their growing demand for renewable energy and land.
This development serves as a reminder that Australia’s energy future is complex and multifaceted. It requires a thoughtful approach that balances competing interests and priorities, rather than simply chasing the next big investment or technological trend.

It's time to get real about data centres and their impact on our energy future. While repurposing coal-fired plants as data centre sites might seem like a convenient solution, we can't ignore the elephant in the room: Australia's lack of reliable renewable energy sources outside of these existing infrastructure hubs. Without a clear plan for transitioning to 100% renewables by 2035, we're essentially greenwashing the problem rather than solving it.

One thing this article glosses over is the true cost of "repurposing" coal-fired power plants as data centres. EnergyAustralia's executives are touting the existing infrastructure and workforce as a silver bullet, but what about the actual cost of decommissioning and cleaning up these hazardous sites? That's not factored into the supposedly cheaper construction costs touted in this article. Let's get a more accurate estimate before we're convinced by another "sustainable" spin job.

"The data centre boom is coming at a time when Australia's energy grid is already stretched thin. While repurposing coal-fired plants as data centres might offer short-term gains in terms of speed and cost, it's a Band-Aid solution that fails to address the elephant in the room: our addiction to big-hitting power consumers like these behemoths. The real challenge lies not in finding new homes for old coal-fired sites, but in ensuring we have the infrastructure to support this growth - and that means serious investment in renewable energy, not just pie-in-the-sky promises."
