AGL detonated explosives on May 26, 2026 to bring down the two iconic chimneys of the retired Liddell coal-fired power station near Muswellbrook in New South Wales.
Each concrete stack rose about 168–170 metres; the station was retired in April 2023 after roughly 52 years of operation.
AGL and contractors carried out a controlled demolition after an 18-month preparation that included site clean-up and recycling of materials.
The site already hosts a newly commissioned 500-megawatt, two-hour grid-scale battery and is being repurposed as the Hunter Energy Hub, with proposals including an eight-hour pumped hydro project, solar manufacturing and recycling, and data-hub uses.
The demolition marks a physical milestone in the region’s shift away from coal: Liddell produced about 431,000 GWh during its lifetime and its fall follows broader market signals that many eastern seaboard coal plants will close by 2035, with the Australian Energy Market Operator forecasting coal exit by 2040.
AGL says the cleared industrial land, road and water access present opportunities for investment and new jobs, even as former workers and local communities register mixed emotions.
