If electricity consumers were not already being squeezed by the closure of Victoria's coal burning Hazelwood power station, an extraordinary lack of wind in the past few months has certainly compounded the problem. The large wind-focussed generator, Infigen Energy has been forced to downgrade its full-year profit forecast due to what it says has been the least windy period it has endured put its current capacity together in 2012.
Electricity prices will jump another 20 per cent, partly because global warming policies are closing cheap coal-fired power plants. With even supply now threatened, the Turnbull Government is considering building its own plant.
This important study has identified flaws in the current compliance testing for wind turbine noise and further outlined the methods necessary for identifying and measuring the low-frequency, pulsation that isoften times reported by those impacted by the turbines. Specifically, the "presence of amplitude modulation in the low frequency region, that modulates at an infrasound rate, at or near the threshold of hearing" has been identified and may support the symptoms reported by Dr. Nina Pierpont in her work, Wind Turbine Syndrome. The introduction and conclusion of the paper is provided below. The full paper can be accessed by clicking the links on this page.
A spokesman for Mr Fydenberg said the "Government considered the proposed wind turbines would create a considerable, intrusive visual impact". "This would affect the spectacular and scenic landscapes for which the world heritage island group is recognised," the spokesman said in a statement.
Victorian firm Maddens Lawyers filed the class action against Infigen Energy Ltd in the NSW Supreme Court after a crow electrocuted by a transmission line carrying power from the company’s Woodlawn wind farm sparked the fire, which burned 3400ha and caused up to $20 million damage.
This week we learned that the complete power blackout that occurred in South Australia last September was due to the existence of a large number of wind farms that simply ceased to operate in the context of a strong storm, in turn causing the interconnector with Victoria to trip.
Overly sensitive protection mechanisms in some South Australian wind farms are to blame for the catastrophic statewide blackout in September last year, the Australian Energy Market Operator (AEMO) says.
South Australian power consumers have been slugged for a massive $4.5 million price spike for services that stop energy infrastructure from blowing up. The Australian Energy Regulator released a report on Tuesday night into why prices for services which stabilisethe grid exceeded $5000/MWh in SA on October 18 last year.
New windfarms in South Australia will face tougher technical standards, amid concern the state's heavy reliance on intermittent renewable generators has left the electricity grid prone to collapse. ...AEMO found a failure of windfarms to ride through voltage disturbances contributed to the catastrophic chain of events which caused the blackout.
Taxpayers in South Australia face being slugged tens of millions of dollars for dirty carbon dioxide-emitting diesel generators the Weatherill government wants shipped in by December to prevent pre-election blackouts.
The problem is, the wind doesn't always blow and the sun doesn't always shine. The high peaks in South Australia's energy usage don't always match up with a large chunk of its increasingly intermittent supply. Intermittency isn't the only problem though. Under current market settings, wind farms aren't required to provide the same stability coal and gas has traditionally provided to the energy grid.
In dry, technical language the Australian Energy Market Operator has warned Queensland’s Premier, Annastacia Palaszczuk, that her renewable energy policy could take the state down the South Australian road, where they have the misfortune to pay high prices for unreliable electricity. The Palaszczuk policy would massively increase Queensland’s reliance on intermittent renewables and erode the value of state assets such as black coal-fired generators, which provide baseload power. And all this for no discernible effect on climate change. It is a profoundly irrational course.
After a year of campaigning against a proposed $700 million wind farm, AFL chief executive Gillon McLachlan today begins a legal fight to protect his childhood home before a full-bench court in Adelaide.
Labor’s plan to produce 50 per cent of electricity from renewables by 2030 has been dealt a blow by the national power market operator, which has warned that Queensland’s push for the target could lead to higher electricity prices and an unstable network.
Among the individual submissions, there were 536 against the wind farm and 38 in support of the joint Australian-Spanish venture which plans to install 88 turbines across 23 rural properties in Tarago.
Wind power generators received $600 million in federal subsidies last year, helping to drive an increase in electricity prices for consumers. Data collated by Australian Power Project, which advocates a sustainable national energy policy, showed $588.7m was paid to wind farm operators.
Birds electrocuted by a power transmission line at a wind farm near Canberra in January sparked two bushfires — one of which burned 3400ha and caused millions of dollars of damage in lost livestock and property. The fires near Tarago, east of Canberra, were started at different spots on a transmission line taking power from 23 turbines on the Woodlawn wind farm to its substation.
“The government is talking about using the Clean Energy Finance Corporation to subsidise a coal-fired power station,” he said. “We subsidise wind to make coal uneconomic so now we are proposing to subsidise coal to keep the lights on. Go figure.” “Wouldn’t it be better to abolish subsidies for new renewable generation and let ordinary market forces do the rest?”
Pushing ever more renewable energy into the national electricity network is negligent without new investments in energy storage, Malcolm Turnbull has declared, stepping up his attack on Labor's "complacent" and "ideological" clean energy policy.
Malcolm Turnbull has blasted Labor’s renewable energy “horror show” by seizing on blackouts in South Australia to warn of outages across the country under the “insanity” of Bill Shorten’s 50 per cent renewables target. ...“How many South Australians are worse off because of the Labor Left ideological approach to power? I tell you: every single one."
