Gaia is a cruel prankster.
A $200-million wind farm in northern New Brunswick is frozen solid, cutting off a potential supply of renewable energy for NB Power.The 25-kilometre stretch of wind turbines, located 70 kilometres northwest of Bathurst, N.B. has been completely shutdown for several weeks due to heavy ice covering the blades.
Can't they install electric heaters to thaw the ice off the windmill blades...?.....uh....Can't they install windmills to generate the power needed to run the electric heaters to thaw the ice off the windmill blades....uhh.....
Can't we charge David Suxuki with high treason and crimes against humanity?
Posted by: Eskimo at February 15, 2011 3:09 PMAnd to add even more irony . . . all of these useless turbines are sucking electricity into them to keep the machinery warm.
Wind turbines"delivering" negative energy to the good taxpayers of New Brunswick.
The only thing that is keeping these fans up and not running is the embarrassment that would ensue among our precious politicians and their Eco freak commie pals.
Otherwise, that experiment is over.
Posted by: Abe Froman at February 15, 2011 3:21 PMIt is over Eskimo, the courts should be filled with the Suzukis and Gores and their ilk, this SCAM has broke the western world. 12 jobs! how many jobs were created in Brazil, Denmark, Japan, building these eyesores, hundreds. Canada is just waking up to this SCAM, the monetary hangover is the current disaster. Tell me Mr Suzuki, how can a young family buy 400,000 worth of house and vehicles, without a job, or a job slinging fries, or one of 12 jobs tilting at windmills? No Mr. Suzuki let me inform you, people need OIL jobs and spinoff of OIL jobs to even hope to buy a house in this market you "MAGGOT", as you freely call the rest of us. Love to see imperial David, hang off a monkey board in 30 below with a 30 mph wind, that would soon weed the "maggot" from the men!

These windmills will be regarded as the last vestige of modern society gone mad IMO...After the "big correction" whatever and whenever that will be...After the next dark age, maybe.
Just the thought that Spain literally went bankrupt in the attempt to go all in alternative energy development when we know that oil was what catapulted mankind in the space age in a mere century is just mind boggling.

Throwing ice shards of course is one of the hazards of these things. They can fly for at least half a kilometer.
Eskimo and Fred raise a good point. You cannot 'blackstart' a wind turbine. It will not function from a cold start unless it has current coming into it. What isn't measured is the excitation current being drawn by the turbine. If it's shutdown for high wind or no wind conditions, it's still drawing. So in very low or high wind conditions, it may actually be a load instead of a supply source. When the IESO produces its hourly production numbers and say the gross wind production is close to zero, net production may actually be negative. But this isn't recorded anywhere to my knowledge.
Posted by: cgh at February 15, 2011 4:17 PMNot to worry - those turbines will be back on line soon. In the meantime all those customers of NB Power can use this as an opportunity to meditate on how foolish their society was to ever embark on non-renewable sources in the first place, and buy some carbon offsets until ethical electricity once again becomes available.

I'm thinking you would incorporate heating elements into the blades when they are laminated, or de-icing fluid tubes. Its no different than an aircraft wing in that regard.
I'm amazed they don't have that, myself. There are lots of wind farms on coasts, how do they manage icing in Sweden and Denmark? Or Scotland?

Mostly correct.
It has to be remembered that politicians rely on expert advice to make these policy decisions and all the "peer reviewed" experts said that winter was a thing of the past(which is why the turbines were designed w/o de-icers) and that the CAGW question was settled, argument over.
A lot of the blame lies with the expert climate science liars.(CRU, NASA, IPCC, and touts like Suzuki, Gore, Jones, Mann, Hansen et al.)

Posted by: reg dunlop at February 15, 2011 6:35 PM$200 million to produce 99 Mw!? That's over $2 million/Mw and I wonder if the 99 Mw is real capacity or just imaginary capacity.
I don't think that a coal fired power plant costs nearly that much per Mw of capacity. Hell, I could go to the local hardware stores and buy up all of their gasoline generators and still produce power at a lower capital cost than wind power. It looks like we may be forced to do that if the watermelons continue to have influence out of proportion to their numbers. Something is very seriously wrong when people make idiotic decisions like this.
What is desperately needed is IQ tests for politicians as well as numeracy tests. My latest BC Hydro bill had a notice asking for suggestions on future power development in BC. I'll be recommending damming more rivers, coal power plants and building nuclear reactors. I'll also suggest that we let the military use the current bird blenders for artillery target practice.

Image via Wikipedia
On Jo Nova’s site, the cat is set amongst the pigeons:
A team of skeptical scientists, citizens, and an Australian Senator have lodged a formal request with the Australian National Audit Office (ANAO) to have the BOM and CSIRO audited.
The BOM claim their adjustments are “neutral” yet Ken Stewart showed that the trend in the raw figures for our whole continent has been adjusted up by 40%. The stakes are high. Australians could have to pay something in the order of $870 million dollars thanks to the Kyoto protocol, and the first four years of the Emissions Trading Scheme was expected to cost Australian industry (and hence Australian shareholders and consumers) nearly $50 billion dollars.
Given the stakes, the Australian people deserve to know they are getting transparent, high quality data from the Bureau of Meteorology (BOM). The small cost of the audit is nothing in comparison with the money at stake for all Australians. We need the full explanations of why individual stations have been adjusted repeatedly and non-randomly, and why adjustments were made decades after the measurements were taken. We need an audit of surface stations. (Are Australian stations as badly manipulated and poorly sited as the US stations? Who knows?)
The NZ equivalent to the Australian BOM is under an official review
The New Zealand Climate Science Coalition found adjustments that were even more inexplicable (0.006 degrees was adjusted up to 0.9 degrees). They decided to push legally and the response was a litany of excuses — until finally The National Institute for Water and Atmospheric Research (NIWA) was forced to disavow it’s own National Temperature Records, and belatedly pretend that it had never been intended for public consumption. But here’s the thing that bites: NZ signed the Kyoto protocol, arguably based very much on the NZ temperature record, and their nation owes somewhere from half a billion to several billion dollars worth of carbon credits (depending on the price of carbon in 2012). Hence there is quite a direct link from the damage caused by using one unsubstantiated data set based on a single student’s report that no one can find or replicate that will cost the nation a stack of money. NIWA is now potentially open to class actions. (Ironically, the Australian BOM has the job of “ratifying” the reviewed NZ temperature record.)
Thanks to work by Ken Stewart, Chris Gillham, Andrew Barnham, Tony Cox, James Doogue, David Stockwell, as well as Cory Bernardi, Federal Senator for South Australia.

"Wind farm moratorium not election-based: McGuinty"
"The governing Liberals' surprise decisions to halt off-shore wind farms and freeze the minimum wage have nothing to do with a provincial election that's just eight months away, Premier Dalton McGuinty said Tuesday.
Anti-wind power protesters have greeted McGuinty in many communities across the province, but the premier insisted the moratorium on off-shore projects is not politically motivated.
"People are free to do as they wish in terms of drawing whatever inferences that they desire from the decisions of the government," he said after speaking to a business audience in Brampton, Ont.
"But the fact of the matter is, we've been very aggressive with respect to land-based wind turbines. We will continue to be very aggressive with respect to locating land-based wind turbines here in Ontario."
The government announced the sudden reversal on off-shore projects last Friday, just minutes after McGuinty had finished speaking to reporters."
"But there may be other hurdles ahead.
Last month, a three-judge panel from the Ontario Division Court began reviewing evidence and submissions from people challenging the government's 550-metre setback for wind turbines from homes.
An Environmental Review Tribunal has also been holding hearings in Chatham and Toronto on a proposal by Suncor for a wind farm in Thamesville, which some residents fear will disrupt their sleep and cause other health problems. Those hearings were set to resume in Chatham on Tuesday."

I'm thinking this frozen turbine blade problem is an easy fix.
Shale gas. Simply punch a shale gas well at every wind turbine site, frac the crap out of it and plumb the ensuing gas into the turbine.
I'm sure some kind of burner array could be easily affixed to the leading edge of each blade. For a prototype I envision bar-b-que burners and duct tape but of course the technology will evolve if enough government investments are made in green energy.
Right?

Posted by: Snagglepuss at February 15, 2011 11:11 PMPhantom, the surface area is enormous, so heating is out of the question. As for de-icing fluid, not really possible given that they are in essentially constant motion.
There is no de-icing of the Horn's Reef windmills to my knowledge. That's why ice-throwing can be a problem. They also don't usually get winters cold enough for the salt water to freeze. Gotta love that Gulf Stream, compared to the Labrador Current which hits Atlantic Canada right in the chops.
Cascadian, all that a wind mill does is produce mechanical energy by turning a shaft. This is fine if all you want is mechanical energy to run a very old style water pump. But if you want electricity, you have to do a lot more. It's back to Faraday's Laws and Maxwell's equations of electromagnetic induction.
So you have to have a generator and converter to turn that into electricity. You can only convert it through magnetic fields, so you have to have enough electricity coming into the generator and converter to raise a magnetic field and charge the converter. Otherwise, the turbine just spins and doesn't do anything. The gearbox also needs electricity to run. So if you have a shut down turbine, you need to run the gearbox to get the turbine out of a locked position.
It's very similar to your car. The motor won't turn over by itself. You need a charge into the starter motor to turn the engine over mechanically. Running the starter motor means you need a stored source of electricity, the battery. In the case of turbines, they draw their startup current from the grid they will be supplying. In the case of the wind turbine, you don't need energy to turn the blades; I'm presuming the wind does that. But you need outside supply of electricity to start up all of its electrical equipment.
I don't know how much electricity that is or what the inrush is. However, the manufacturers such as GE or Vesta know it very well, as well as the ongoing operating load.
Nuclear power plants also can't black start themselves. Simply pulling out the control rods in a reactor doesn't start any generation because there's nothing at that point to turn over the main circulation pumps (they are about 200,000 HP synchronous electric motors, at least they are on that scale). And each reactor has four of them. So the nuclear plant has to draw power from the grid to which it is connected to provide the excitation and inrush current for the circulation pump motors (lots of other things too, but those are the main load). The backup diesel generators at a nuclear station are not to allow the reactor to start up. They are there to power all the control systems and ensure that the plant's shutdown systems are all fully powered. The typical requirement in a nuclear plant is about 100% redundancy for diesel generators. Most plants have four of them, and one can fill the minimum requirement, I believe, though it might be two.
Once the plant is running, there's a huge surplus of power. But typical for any thermal plant, internal consumption is about 5% of total output.
So when Ontario had its great electricity blackout in 2003, the only plants that managed to stay operating were the hydro damns, the coal stations, the few gas plants and the four nuclear reactors that managed to go into standby mode before grid rejection occurred. All the remaining nuclear plants could only start up after the grid had been restored.
In Ontario's case, it had to largely restart its system on its own and it took nearly two days for the grid to come back up. (Which took a truly ferocious amount of work by the generators and Hydro One in particular.) In the case of New York, Ohio and Michigan, they could restart quite quickly because they were all surrounded by electrical systems which were not blacked out.

I had no idea there was such a thing as a BC "clean energy act" which is essentially designed to cripple the BC economy. Maybe the BC communist party replaced Campbell's brain with one from a Suzuki clone as right now I can't see any difference between the BC lieberals and the commies. Maybe there's too many bald eagles in BC and it's impacting on the Native Indian salmon fishery and bird blenders are a way of decreasing eagle numbers.
BC Hydro wants to hear from the people of BC about its plans and it's time to let them know at:
integrated.resource.planning@bchydro.com
You can find out more about the proposed lunacy at http://bchydro.com/IRP
At least they consider hydroelectric power clean energy but their plans are to reduce power consumption. That means massive increases in rates as BC Hydro's costs certainly aren't going down. I guess one of the things I can do to dissipate some of the rage is start planning now for what I can do for the next human achievement hour. A good opportunity to give my house electrical system a test -- I've got 200 amps coming in and will see if I can use 190 Kwh during human achievement hour. Just wish I had some of my old power hungry PDP-11's which my wife made me give away (at least they went to a good home).

cgh, I hadn't considered surface area to be heated in my thinking. Usually with aircraft they heat the leading edge and the rest pretty much cracks off in the breeze, but with an 80 ft blade that could lead to some healthy weight imbalances as ice comes off unevenly. Leave one blade out of three loaded for a couple of turns and you'd probably hear a big kaboom from the main bearing.
Just goes to show how very not ready for prime time this tech is, and gee whiz they freakin' went and installed it anyway, billions of dollars worth.

ORNL Scientist Tells The Truth About Global Warming

Posted by: trappedintrudeaupia at February 16, 2011 12:44 PMPhantom: "a big kaboom..."
No bloody kidding.
Ontario Hydro did a large series of safety tests on wind turbines in the 1970s. These were just little 150 kW machines, not the 1-3 MW jobs we have today, so their blade length was trivial compared to the modern monsters.
OH found that the MEDIAN (not average) throw distance on blade separation from the hub was nearly 500 metres. At a weight of about 500 kg, one of them would go through a house roof. In short, we knew all the limitations of wind turbines more than 30 years ago. The key factors were speed of rotation and trajectory on separation.
Now we're dealing with machines with blades 10 times that mass. They won't go through the roof, they'll go through to the sub basement and take everything with it.
Also, no one cares about ice flaking off wings at 30,000 feet. It sublimates or melts long before it hits the ground. But ice flung off a wind turbine blade is going to hit something.
Madasl, I looked at the Weston article. All that Coon said in essence was that he didn't know anything. (Gee, what a surprise coming from that eco-twit.)
Favill: God is unnecessary in this case. Physics and engineering long ago determined that these things had severe limits. What it shows is the extent to which the greens wanted to come up with an alternative to nuclear, because that's most of what it's always been about until the AGW scam came along. Then they also became the preferred alternative to all fossil fuels as well.

“For us, cold and dry weather is good and that’s what’s typical in the region. Cold and wet weather can be a problem without any warmer days to prompt thawing, which has been the case this year.
Umm. The winter I spent in New Brunswick was awfully damp compared to a good prairie winter...
