This article is part of New Scientist’s ongoing investigation into what caused the fire at Mitchell Power Station, in northern New South Wales, Australia.
A spokesman for the NSW fire service, which was the first to respond to the blaze, said it was not possible to establish a cause of the fire, which broke out in a power plant’s fuel cell and then spread.
He said investigators were “still trying to establish exactly what caused it”.
The Mitchell power station, a state-owned power plant owned by the Mitchell Group, employs more than 100 people and has a capacity of about 100 megawatts (MW).
It was originally built to power a nuclear power plant in the 1970s, and has since been used as a storage facility for electricity generated by the power station.
Power station workers had been working in the fuel cell facility for about six months, when the fire started on Tuesday.
A spokesman said: “At this stage we don’t have any indication of what caused this fire.”
It was quite a long time ago.
It could have been the result of a power failure.
“He said the fire had burned out some fuel cells within the facility, and firefighters were working to remove the remaining fuel cells.
The power station has been closed since Thursday.
