Jun 6, 2026 - How a flooded gold mine became Australia`s most powerful hydroelectric power station
A gold mine in Far North Queensland shut down in 2001 after producing more than 3.4 million ounces of gold. For 25 years, two massive open pits just filled up with rainwater — sitting there, doing nothing. In November 2025, those same flooded pits became a power station. This is the world`s first pumped hydro energy storage system ever built inside an abandoned mine, expected to be operational by 2027. And Australia may have 37 more of them — collectively storing over 540 gigawatt hours of clean energy. This isn`t a story about solar panels. It`s a story about gravity, water, and 150 years of mining damage that could turn into clean energy infrastructure.
