Record Wind Power Levels Trigger Energy Price Fall Across Europe
New submitter Forty Two Tenfold writes "Electricity prices across Europe dropped last month as mild temperatures, strong winds and stormy weather produced wind power records in Germany, France and the UK, according to data released by Platts. The price decline was more marked in Germany, where the average day-ahead baseload price in December fell 10% month over month to €35.71/MWh. On a daily basis, December was a month of extremes for Germany, with day-ahead base prices closing on December 10 and 11 at less than €60/MWh – the highest over-the-counter levels seen all year – only to fall to its lowest level December 24 to €0.50/MWh."
Considering that money is not going to subsidize some Arab regime, does not add carbon to the atmosphere, and does not use up a non-renewable resource, I'd say it's a great deal. More, please.
Please note that those prices are day to day EPEX spot prices and have as much in common with the rate you get charged as a consumer/business. Even less than brent spot prices influence fuel prices at your gas station, since most electricity consumers have a yearly price agreement. The huge variation is due to the over-capacities of German networks during high wind/ sun times. This overload has to be sold to other meta consumers if necessary at a negative price. This is one of the reasons why a lot of companies here in central europe are investing in transportation (high voltage DC networks) and means to store the overproduction (water/salt/batteries).
€35.71/MWh from the generator is not exactly cheap by US experience.
The cheapest electricity in the USA today is in Kentucky (coal country) where it goes for about 6 cents/kWh. That is about $60/MWh, which is considerably more than 35 euros. I live in California, and I pay from 12 to 30 cents per kWh ($120 to $300 per MWh) depending on usage tier.
Not sure what you are thinking or if you're confused about units, etc. but ... /MWh which is close to the euro 35 ($47) price in TFA.
A quick search of US Wholesale prices shows a range of $31 to $71 for last year with highest prices in the Northeast. California was $42
So... price for this wind power is on par with US wholesale prices for all (coal, hydro, NG, etc.) averaged together... not really 3x.
I don't read your sig. Why are you reading mine?
That's not just not exactly cheap, that's 3x the cost of power here in California
I think you need a new calculator. 35.71 euros is about $49. That is less than 5 cents/kWhr. Where in California are you getting a kWh for one third of a nickel?
Just to save time, let's all agree that wind power could never, ever, ever work in North America. Or solar. Obviously the blah blah blah mumble mumble obfuscate is so different here that it would be impossible.
Also, North American wind is like TOTALLY different from European wind.

wind doesn't vary on a minute by minute basis, though. Perhaps we don't need batteries, so much as we need a way to communicate pricing signals to the consumers.
If I had a device that I could set price points to, say, start a load of laundry or run the refrigerator compressor, or hold off on the AC when a price transmitted by the power company is high or low, I could make my own demand follow the actual supply more closely.
Just because I might have a few big-power needs, doesn't mean I can't be flexible with when they are executed, if I have some way of knowing when a good time is.
I would want the information to be a price that I choose, though, rather than the "smart metering" I've seen elsewhere where the device allows the power company to decide when your devices run. If I'm picking, I can override, for instance if I'm going to an interview in a few hours and just noticed I need to wash a suit or something.
Can you be Even More Awesome?!
A better solution may be the development of longer term energy storage and batteries
An even better solution is to pass through the fluctuation in the wholesale prices directly to the consumers. This will stimulate a demand for appliances that are "price aware". So refrigerators, freezers, and AC will pre-chill when power is cheap and coast when it is not. Water heaters, clothes dryers, etc. will disconnect their heating elements when prices surge. Instead of only trying to smooth the supply, we should try to change the demand to meet the supply, and market prices are the best way to achieve that.
My calculations are 60 euro time 1.37 equals 82.2 dollars divided by 1000 or .082 or 8.2 cents per kilowatt hour. .5 euro times 1.37 equals .685 dollars divided by 1000 or .000685 or .0685 cents per kilowatt hour. The most expensive is close to what I pay and the cheapest is far less. At the cheapest rate my electricity bill would be less than 1% of what I now pay. 14.5 kilowatt hours per penny is almost free.
Yes, the producers will pay you to use (more) electricity, happens when the cost of stopping and restarting a power-plant is high and demand is low.

I'm from Portugal, this type of "green-article" never tells the whole story .
,this is terribly expensive for us, because the more subsidized energy is produced , naturally we paid more and more. Portugal already has one of the most expensive energy prices in Europe, but as the price of energy sold to public is regulated, dont reflect the real and crazy cost, consumers have accumulated a huge tariff debt to the system . In Portugal this tariff debt already exceeds 4000 million € in Spain now exceeds € 25000 million €.
We have a serious problem with subsidized renewable energy , as has Spain , or Germany ( but these are rich and in Portugal we live in a severe crisis).
When there is too much wind and hydro generation, prices in the energy market fall, BUT producers of renewable energy ( exluindo large hydro ) receive the same guaranteed rate ( feed-in tariff). As these producers have priority in the system all energy produced by them have to be bought, even if there is much cheaper energy in the market (gas, nuclear, oil, etc), even if it's free as has happened several times in the past (in Germany last year energy price at one day was negative) we have to buy the subsidized energy !
So actually what happens when there is too much wind and rain
To get an idea of prices paid to subsidized energy, here I leave these two pictures:

Annual changes in the average cost of energy subsidized vs. average market cost: http://i.imgur.com/OFn71pI.png
Although wind power does not contribute to global warming through greenhouse gas emission, it does extract kinetic energy from the atmosphere and therefore may alter global climate even at continental scales
It may be the lesser of evils compared to some other supplemental energy options but it isn't perfect- and it isn't a good candidate for base load
Not sure what you are thinking or if you're confused about units, etc.
I'm pretty sure the poster was dividing 35.71 by 1000 to get KWh price and getting .3571 rather than .03571. Then they said "47 cents per KWh!? That's 3X our residential price!". Fairly simple, and easy, mistake to make when working with with one set that scales by 1000 (kilo, mega, giga, etc.) and another item that scales by 100 (dollars to cents).
