Smoke stack at one of Australia’s last oil-fired power stations demolished in controlled explosion

Hydro Tasmania has announced the demolition of the 110-metre smoke stack for the shuttered Bell Bay power station, one of the last oil-fired generators in the country.

The spectacular demolition occurred on Monday near the banks of the Tamar River. Hydro Tasmania says McMahon Services used 41 kilograms of explosives and electronically programmed detonators to ensure precise timing and a safe collapse of the structure.

“The demolition of the stack was a big moment the team had been waiting for and they did a fantastic job,” said project director Aaron McCreath.

“Bringing down such a tall and narrow structure is very complex work and requires a highly skilled specialist team.”

The Bell Bay power station was constructed between 1971 and 1974, and the two 120 megawatt steam turbine generators were powered by heavy oil shipped up the Tamar River by tankers. It was used when water levels were low and Tasmania’s hydropower stations needed backup.

The Parsons generators, along with their associated boilers and other equipment, were built in England. In 2003, Bell Bay was converted from oil to gas, extending its working life until it ceased operation in 2009. 

Hydro Tasmania says works at Bell Bay are nearing their conclusion so the site can be repurposed. All activity is expected to be completed in early 2026.
