The end of Latrobe Valley coal – in pictures - The Guardian

The Latrobe Valley in Victoria, home to Australia's largest coal-fired power station fleet, is entering terminal decline. The Guardian's photo essay documents the shutdown of coal assets that once supplied nearly a quarter of the nation's electricity. No new timeline or replacement capacity figures are provided in the article.

Where this fits

Australia is retiring firm, dispatchable power faster than it is building the transmission, storage, and gas backup needed to maintain grid reliability without it. Latrobe's closure removes roughly 7.6 GW of coal capacity that ran at high capacity factors and required minimal weather-dependent firming. The transition plan, solar, wind, and batteries, outsources manufacturing to China and relies on gas plants to fill the gaps when weather does not cooperate. This is a reliability pressure, not a cost one: the headline celebrates the end of coal without addressing what firm power replaces it, and at what whole-system cost.

What it means

Latrobe's retirement is necessary on emissions grounds. Coal has the highest lifecycle emissions of any major generation source, and Australia cannot decarbonise without closing these plants. But the decarbonisation path chosen, renewables-plus-gas, locks in gas firming for decades, foreign ownership of the solar and battery supply chain, and a grid vulnerable to supply shocks that would halt China's factories or disrupt shipping. A firm, low-emission alternative, nuclear, remains banned by law. Australia is trading energy independence and grid resilience for a renewable build whose real footprint and supply-chain exposure rival its emissions gains.

Energy security is national security. This connects to the wider case at Unprepared: Australia's dependence on a strategic rival, and how ready it is for the world that is coming.
