A $3 MILLION wind farm turbine caught fire while dozens shut down at the time South Australia most needed them -- when a heatwave left 63,000 South Australian homes without power last month.tags: wind power, wind energy
Adding to the drama, firefighters could not extinguish the blaze because the tower was too high at 67m [220ft].
Lack of wind and automatic shutdowns triggered by hot temperatures were to blame for the state's 180 turbines producing just 10 per cent of their maximum power capacity during the January heat wave, according to experts.
The experience proved SA could not rely on wind power to provide electricity when demand was greatest, the Electricity Supply Industry Planning Council (ESIPC) said.
"You never know if the wind will be blowing when you need it to or if wind turbines will shut down," ESIPC spokesman Brad Cowain said.
Operators of the Lake Bonney wind farm, where the turbine fire occurred on Sunday, January 22, said all of its 46 turbines had automatically shut down during the heat wave when temperatures exceeded 40C [104F].
... [Wind farm operator Miles George of Babcock and Brown Wind Partners] said the turbine fire ... had been caused by an electrical fault while maintenance crews were working on it after it had shut down.
Around 3pm, 40 CFS firefighters and six trucks rushed to the wind farm to extinguish the blaze but fire hose water couldn't reach the steel generator at the top of the tower.
Instead, the firefighters watched as fire destroyed the $3 million turbine – which weighs 75 tonnes -- and extinguished spot fires ignited by ashes from the turbine blaze.
... [D]uring Saturday's peak power demand wind farm output plummeted to just 2 per cent of capacity, producing enough power for only 3500 homes, according to ESIPC. This compared with the maximum capacity of 318MW to power 175,000 homes. SA leads the nation in wind farm energy with five established sites -- Starfish Hill, Canunda, Wattle Point, Cathedral Rocks and Lake Bonney.
There are numerous other approved wind farm developments including an AGL plan for 43 turbines at Hallet in the state's Mid North.
But AGL also plans to more than double the capacity of its nearby gas-fired plant, from 180MW to 430MW, at a cost of more than $100 million to ensure peak demand during hot weather can be met.

Wind farms conk out in heat wave
The Adelaide (South Australia) Advertiser has a story today about the sorry performance of the state's 180 wind turbines during the January heat wave. Even if there were some wind, many of the turbines shut down because it was too hot. Then one of them caught fire. Although firefighters couldn't do anything about the turbine, at least they were there to put out the spot fires started by falling debris. Imagine such a fire amidst the brush of a remote ridgeline.

Groups raise concern over efforts by wind industry to revise USFWS' interim guidance outside federal law
[press release]
Rowe, MA (February 10, 2006). National Wind Watch, Inc., the Humane Society of the United States, the Alliance to Protect Nantucket Sound, and Juniata Valley Audubon, Chapter of National Audubon Society, called on Interior Secretary Gale Norton and other federal officials to confirm whether the Fish and Wildlife Service intends to comply with the basic openness and accountability of the Federal Advisory Committee Act (FACA) with regard to the "collaborative process" being pushed by wind energy proponents to revise the Fish and Wildlife Service's (FWS) Interim Guidance on Avoiding and Minimizing Wildlife Impacts from Wind Turbines.
In a letter to Secretary Norton and others, the groups cited the critical importance of the FWS adhering to FACA requirements for public access and accountability given the "significant public controversy surrounding the impact of wind turbines on our nation's treasured wildlife -- in particular on bats and birds -- and considering the current rapid expansion of wind power throughout the country and the potentially devastating impact this expansion could have on wildlife if the turbines are not properly sited." In the letter, the groups stated "We are very concerned that if the FWS does not fulfill this FACA requirement, then the process will simply be an opportunity for the wind power industry to force its views on the agency, and will result in the agency revising its Interim Guidance in a manner that makes turbine siting and operation easier for the industry, but detrimental to wildlife."
The first meeting of the Policy Group for the collaborative was scheduled for February 9, 2006 in Washington, DC. The meeting was canceled when the Fish and Wildlife Service advised participants that it needed more time to evaluate the applicability of the Federal Advisory Committee Act (FACA) to the collaborative process.
National Wind Watch spokesperson, Lisa Linowes, was pleased with the FWS response to the letter but expressed concerned that the collaborative effort was permitted to go as far as it did. "The groups represented by the letter have consistently raised legitimate and important conservation concerns about industrial wind power projects. It is essential that there be a fair representation of our views and expertise," she said. The letter was submitted to the Interior Department by Meyer Glitzenstein & Crystal, a public-interest law firm in Washington D.C..

market scams, dead bats, and big business
Here are a few abstracts from Windpower Monthly's February issue.
China changes tack on wind market structure and drops fixed purchase prices for competitive tenders: Companies which a short time ago were rushing to develop wind projects in China are now having second thoughts after the government announced last month it would not be introducing a premium wind power tariff, as widely expected. Instead, the market structure will be a competitive bidding process controlled by government. "The zeal for wind development in China is likely to cool down," says Zhu Junsheng of China Renewable Energy Industries Association.
Plans for Scandinavian green certificates market hit icy patch: Europe's first cross-border market for trade of green power certificates is looking unlikely to go ahead at the start of next year as planned. All eyes have otherwise been on Norway and Sweden to demonstrate that the environmental value of renewable energy is a commodity that can be sold separately from the physical electricity. Green certificate trade, increasingly common in America, allows a country with poor wind resources to buy cheaper wind power from a distant windy neighbour. [This echos the arrangement of powerful nations enriching themselves with the resources of weak nations. --KM] But Norway is still wrangling over the details, while a Swedish fear is that as long as Norway can produce wind power more efficiently than Sweden, Swedish subsidies to renewables will end up in Norwegian pockets. ... [W]ind industry views remain mixed on whether these are teething problems or a more fundamental flaw in the concept of green certificate trade.
GE Financial Services aiming to be world's biggest wind power investor: With last year's purchase of seven small German wind farms and the commissioning of a 50 MW project in California, GE Energy Financial Services (EFS) has joined the list of institutional investors aiming to build substantial portfolios of wind plant assets. Right now wind is a "sweet spot" for new energy investment, says the company's Tim Howell. This year EFS is forming a dedicated team to focus exclusively on renewables, chasing deals in Europe and the US. We interview the men with the ambitions -- and the billions of dollars -- to make EFS the largest, most profitable owner of wind assets in the world.
Investigating mystery bat deaths in Canadian wind farm: A leading Canadian power producer is launching two bat research programs after site monitoring at a southern Alberta wind farm revealed hundreds of bat mortalities. About 90% of the bodies were found during the fall migration in August and September. The mortalities were largely silver-haired and hoary bats, neither of which is a species at risk [small comfort if you or your mate is one of the individuals killed --KM]. The company is funding research to track bat behaviour and hopes the findings can be used to identify potential issues at other sites.
Merger of American power giants seen as benefit to wind industry: A pending merger between US electricity majors FPL Group and Constellation Energy will create a giant among giants and has likely wide-reaching implications for the future of wind power development across the country. "Constellation has flirted with the wind industry and as a combination they'll be the leading players in the market," says Randy Swisher of the American Wind Energy Association. "It's very, very interesting." FPL assures that its intention to add up to 1500 MW of wind power to its portfolio remains unchanged. "A market with larger players and larger control areas is more attractive to the wind industry," adds Swisher. [This, along with the GE story above, underscores that industrial wind power is not an alternative to but increasingly a symptom of the same big-energy control that got us into the mess we're in. --KM]

More gearbox failures in wind turbines
The Associated Press reported yesterday from Minot, North Dakota, that a couple of three-year-old wind turbines haven't been operating for the past couple of months because of gear box problems.
"It's sad to see mechanical failures and we've had our fair share," said Bruce Carlson, president of the Verendrye Electric company. And Ron Rebenitsch, a Basin Electric engineer from Bismarck, added, "With the gear teeth stripping out, the turbine could run wild and self-destruct. Those turbines are under a tremendous amount of stress, and there are many parameters for a turbine to operate safely. It's a complex mechanical device, subject to failure."
"Gear box problems are not uncommon," said Randy Bush, a resource coordinator for Basin Electric. "At Edgeley, where they have a lot more towers, they have the same issues to deal with that we have."

Anarchy
| Ever reviled, accursed, ne'er understood, Thou art the grisly terror of our age. "Wreck of all order," cry the multitude, "Art thou, & war & murder's endless rage." O, let them cry. To them that ne'er have striven The 'truth that lies behind a word to find, To them the word's right meaning was not given. They shall continue blind among the blind. But thou, O word, so clear, so strong, so true, Thou sayest all which I for goal have taken. I give thee to the future! Thine secure When each at least unto himself shall waken. Comes it in sunshine? In the tempest's thrill? I cannot tell -- but it the earth shall see! I am an Anarchist! Wherefore I will Not rule, & also ruled I will not be! -- John Henry Mackay |

Wind turbine noise -- a primer
A good overview of the wind turbine noise issue, written by physician Nina Pierpont, is available at www.aweo.org/Pierpont-noise-060204.pdf (40 KB). She explains the difference between A-weighted and C-weighted sound measurements and presents evidence that the C-weighted sound level from industrial wind turbines is much greater than the usually cited A-weighted level. The C-weighting includes more low-frequency sound, which can have a serious impact on quality of life and even health.
Pierpont also puts the sound levels of wind turbines and their impact into the context of current environmental and health guidelines.

$100,000 per minute
That's what the Department of Defense says the U.S. is spending on the occupation of Iraq: $4,500,000,000 per month.
That's $54,000,000,000 per year, but Bush just asked for $120,000,000,000 more from Congress for the rest of 2006, most of it for the Iraq operation. It is estimated that $250,000,000,000 has already been spent for Iraq since the invasion in March 2003, almost three years ago.
So it looks like the cost is more like twice what the DD says: $200,000 per minute, $300,000,000 per day, $9,000,000,000 per month.
If you're going to destroy a country, it obviously requires a hell of a lot of cash to do a thorough job of it. Sacrifice is demanded from all of us.
