Sharing infrastructure and coordinating energy use could halve industrial electricity costs - Climateworks Centre

Climateworks Centre has modelled that shared electricity infrastructure and coordinated industrial energy use could reduce electricity costs for heavy industry by half. The analysis points to synchronising demand with renewable generation, pooling infrastructure investment, and co-locating energy-intensive processes as paths to lower per-unit costs.

Where this fits

This is a cost story masquerading as a technical solution. Climateworks is right that coordination cuts waste and spreads capital. But halving costs by synchronising demand to renewable supply admits the core problem Energy Realism has been tracking: weather-dependent generation requires either that customers flex their load or that the grid holds vast reserve capacity. The infrastructure that underpins "half-cost" electricity is not just local co-location; it is a transmission network sized for peak renewable output, peaking plant or battery storage to cover gaps, and industrial processes rewired to run when the sun shines and wind blows. That overbuild and its firming cost are the bill being deferred in the headline.

What it means

If heavy industry can halve electricity costs only by accepting dispatch that follows renewable weather patterns, Australia is pricing reliability out of the offer, not eliminating it. The cost is shifted. A firm, dispatchable alternative, nuclear generation, would allow industrial users to run on a stable schedule without bidding for renewable peaks or investing in their own storage. Instead, law forbids it. Australia is choosing a path where industrial competitiveness hinges on weather forecasting and China's willingness to supply battery inverters and critical minerals on time. That is not cost reduction. It is cost displacement and strategic risk, compounded.
