The eight chimneys of the Hazelwood power station have been demolished by the plant's owner, the French electric utility company Engie, which plans to remove the entire coal-fuelled plant by 2022.
The 137-metres chimneys, which had soared above the town of Morwell in Latrobe Valley in the state of Victoria for 50 years, could be seen collapsing on Monday after being knocked down by controlled explosions, sending clouds of dust and debris into the air.
Engie said that the demolition of the chimneys, which were built in the 1960s, was crucial due to a high asbestos concentration in the plant and the heavy carbon emissions caused by it.
The plant was closed in 2017 and the Hazelwood Power Corporation was heavily fined for failing to deal with a bushfire which reached its coal mine in 2014 and put the employees and residents in danger.
The power station used to produce about one-quarter of the electricity in the state of Victoria and had 750 employees working in it.
