The cause of a fire at Yallourn Power station on Thursday afternoon remains under investigation, as Energy Australia works to assess the full extent of damage.
Twenty-five firefighters were called to the station on Thursday afternoon after scaffolding planks on a boiler house roof caught fire.
The Country Fire Authority deemed the blaze non-suspicious.
With damage only caused to the roof of the boiler house, electricity generation by the power station was not impacted.
“It wasn’t a big fire, it was a relatively small fire. Once we gained access the fire was extinguished relatively quickly within 30 minutes,” Morwell Fire Brigade Operations Officer Shane Mynard said.
Firefighting applicances from Morwell, Newborough, Yallourn North and Traralgon attended the scene for about an hour and-a-half.
“The main reason we were there for some time was due to the access, understanding that in a power station there are walkways, gantries and scaffolding to get through,” Mr Mynard said.
