Climate writers should know intermittent energy from wind and solar cannot support grid-scale power 100 per cent of the time. It needs to be backed up with energy storage. This is why former prime minister Malcolm Turnbull launched the Snowy 2.0 pumped hydro scheme, the cost of which has blown out from less than $3bn to more than $6bn, according to Giles Parkinson at the RenewEconomy website.
The Hallett wind farms, operated by companies wholly owned at the time by power generator AGL, had failed to obtain written approval from the network operators for critical settings designed to allow their wind turbines to ride through disruptions to the electricity grid. In action brought by the Australian Energy Regulator, the Federal Court heard on Friday that while the failure to obtain approval was inadvertent, the settings applied were insufficient to cope with the disruptions to the network during the black system event.
The recent addition of two of the state’s biggest wind farms helped Western Australia set a new benchmark for wind output in late June, although overall wind generation had been badly impacted by the damage wrought by Cyclone Seroja on transmission lines in April and May.
A formal review of the blackout found overly sensitive protection mechanisms in some South Australian wind farms were to blame. The Australian Energy Market Operator (AEMO) found the unexpected operation of the control settings resulted in the sudden loss of generation from the wind farms. In the court proceedings, both Pacific Hydro and Hornsdale admitted that they applied repeat low voltage ride through system settings to their generating units without prior written approval from AEMO and ElectraNet.
Developers of a planned sprawling Gippsland windfarm with turbines among the tallest in the country have sought an independent panel to assess and approve the project. ...Objectors claim the 250m turbines pose a fire risk and may hamper the efforts of water bombing and retardantspraying aircraft in the blazeprone part of Victoria.
The proponent behind the mammoth Golden Plains Wind Farm near Rokewood has denied reports less than the planned 228 turbines will be built. In a statement, a WestWind spokesperson said it was “inaccurate” to suggest the scope of the project had changed.
Australia’s biggest wind farm is now all but mechanically complete. The last of the 149 turbines at the 530MW Stockyard Hill facility in central Victoria has been installed, three substations are complete and energised, and yet – more than one year after the original timetable – the facility is not producing power.
The company behind a planned wind farm on Brown Mountain has suspended the development claiming continuing global uncertainty due to the coronavirus. The news came as somewhat of a relief for residents in the area, who have been campaigning against the development for more than three years.
Fines totalling $26,640 have been issued to a NSW windfarm for failing to meet environmental approval conditions.
The Robbins Island wind farm is the epitome of bad planning. Environmentally, it is placed in the middle of an important bird habitat. It proposes a private bridge and causeway across a sandy channel, more than 1400m long, and destroys one of the great vistas of the North-West coast. It also relies on a 170km long high voltage transmission line, across forest and farmland. It is directed to a group of dams that should be dedicated to hydro irrigation.
Police are investigating an incident at the proposed Delburn wind farm in Victoria’s Latrobe Valley, after a meteorological mast installed at the site was vandalised, causing it to collapse.
But the 20-tonne, 68-metre-long turbine blades were too big to move around many of the corners on rural roads. The team had no choice but to tackle the busy Great Western Highway over the Blue Mountains and then down the steep Victoria Pass, Mr Andrews said.
Energy output has flatlined at Queensland’s biggest wind farm with no electricity sent to the grid for more than a week straight. The Mount Emerald Wind Farm has not produced a kilowatt of power since Monday last week – and it was a similar story earlier in the month.
Tilt Renewables warns of hit to earnings after massive Dundonnell wind farm faces commissioning delays, company cites “insufficient clarity” from AEMO.
Goldwind Australia took the reins on the Dalveen-based project in early 2018, which first became a realisation under the stewardship of Brisbane-based businessman Tim Lucas. Since the takeover, there has no been no news on when or if the project will go ahead. More damning still, there’s no trace of the project on Goldwind Australia’s website which lists their projects that are in operation, construction or planning phases.
About 200 workers are in limbo after work on Australia's largest wind farm arm stalled, with the company responsible for installing the 126 turbines suffering "frustrating" delays securing a Queensland d building licence.
Forest Wind, the proposed wind farm project to be built between Maryborough and Gympie, already has opposition from some Fraser Coast residents.
Plans to build a huge wind farm in Victorias Latrobe Valley, overlooking the site of the now closed Hazelwood coal-fired power station, have been revised down again, from 35 turbines to a total of 33.
OSMI released a revised design for the Delburn Wind Farm last week, which reduced the number of turbines a second time.
