Last month, Dundonnell was also hit by a fallen blade at one of its Vestas turbines, which brought production across the wind farm to a halt for a few days as the cause was investigated. Campbell says it is clear that the blade fell because bolts holding it to the hub became loose, but the question of why those bolts became loose is still under investigation.
Tilt Renewables’ massive Dundonnell wind farm in Victoria is gradually powering back up one week after the project was shut down after a 73 metre, 70 tonne blade fell off one of the project’s 80 newly installed Vestas turbines.
The blade fell around 8.30pm and the company has since removed all turbines from operation while an investigation of the damage occurs. "A root cause analysis will be completed in conjunction with the wind turbine manufacturer, Vestas, which will inform the assurance process on the other turbines prior to these being returned to service," Mr Campbell said.
It's estimated the blade came adrift around 6:40pm, the same time as the storm passed through the area. It's not yet known if the storm caused the turbine to break. The Lal Lal Windfarm consists of 60 Vestas V136-3.6 MW. The 228 MW facility was placed in service around June 2019.
Several Queensland Fire and Emergency (QFES) crews attended the blaze, which ignited about 3pm. A QFES spokeswoman said crews stood by for safety in the event that it led to a grass fire.
An Antarctic research station is relying on diesel generators after a wind turbine collapsed overnight.
Wind farm operator REpower is investigating a lightning strike as a cause of the break, which threw large pieces of debris. The blades attached to the six 66m-high towers 3km from the Victorian coastal township of Wonthaggi can reach speeds of more than 200km/h at the tips.
Hobart people are being used as guinea pigs in an experiment to test untried wind turbines, Hobart City Council aldermen said last night. They expressed fury at the failure and damage to the turbines on Hobart's waterfront Marine Board building on August 11, coming after the council had included safety concerns in its opposition to the turbines.
The four wind turbines on the Marine Board building will be shut down until a full investigation has been done by Workplace Standards Tasmania. Roy Ormerod, general manager of Workplace Standards Tasmania, confirmed yesterday the turbine's supplier, I Want Energy, had been ordered to turn off the turbines.
"While I am happy the fail-safe mechanism worked, it is disappointing that despite induction processes being undertaken ... human error has been found to be the cause of the problem."
They were designed to withstand cyclones but yesterday's blustery conditions were enough to wreck two wind power turbines on top of the Marine Board Building. The turbines were seen spinning out of control in winds of up to 54km/h just before midday - before two blades came loose and fell in on themselves.
One of Verve Energy’s wind turbines at the Esperance Wind Farm was hit by lightning last Saturday week, shredding the blade and making the turbine inoperative. Technicians were at the site last Friday doing routine maintenance on other turbines and say that the damaged turbine has been made safe for the time being.
Windflow Technology could face a bill of nearly $1 million for repairs to turbines it has sold to NZ Windfarms. An independent expert's report on repairs or retrofits to Windflow Technology's turbines estimate the total cost at just over $966,000 for repairs excluding replacing blades and any consequential failures. Windflow has released a statement about the report.
A wind farm turbine caught fire at the Cathedral Rocks Wind Farm in the early hours of Tuesday morning. ...The company said yesterday it expects the damage bill to be about $2 million, but it would determine an exact amount when it finishes its investigation.
A $6 million wind turbine has caught fire near Port Lincoln, starting blazes on the ground as embers fall. The fire, at the Cathedral Rocks Wind Farm about 30km southwest of the town, was first noticed by a boat about 1am.
The talk in the local community is that five of the 12 turbines at Toora are now shut down because of equipment failure, the warrantee period has expired and they can't get parts. This wind farm is not particularly old and it's now limping along with a 42% reduction in power output. It's probably a good time to get this junk off the Toora hills....... This mucking around with turbines all adds to the cost of something that is nothing more than a hoax, which would all be pretty funny if it wasn't subsidised by the public purse.
