Its about 15%, but you know what, we're still building turbines.

How about we discuss the effect of inexorably rising oil prices on electricity prices too?


None. Energy can be stored.


Which farms are unviable?

Where exactly did you get 15% from ? If I was you I would find a new source.

Because yoru source is telling you lies. Not even little lies but HUGE BIG ones.

For today

Demand http://www.eirgrid.com/operations/sy.../systemdemand/

minimum demand today was at 5am this mornign and was 2733 MW Peak was at 9:45am and was 4028Mw

Supply http://www.eirgrid.com/operations/sy...indgeneration/

Maximum supply from wind today was just after midnight and was approx 70MW. thats right seventy

yesterday it was 140MW

Day before 520 (but at midnight at time of lowest demand but was still only 14% of requirements.

Day before max output of 580 MW.

Day before that 120Mw

Day before that 260Mw


The original link you posted was for 2 hours on one particular date. 2 hours.

Even at the peak of oil prices wind power was not competitive and required support and that was before taking into account the cost of the backup supplies?

There is no way of storing enough energy to make wind a secure power source. NONE and that includes the spirit of Ireland proposal as it stands. Even with 3 full reservoirs of their maximum proposed size it wouldn't have gotten us through the last 3 months. For that matter not even 3 weeks.

The data is there. its staring you in the face and yet you choose to ignore it. Why ?

New record as wind power meets 39% of electricity demand - The Irish Times - Thu, Aug 06, 2009

And that was just during Dan Boyles last speech !!!!!

if ryan does a half smirk with those puppy dog eyes just one more time so help me god i will poke his face gaaa gaaa

You're being very selective in your choice of data:

Maybe its slightly less than 15%, or slightly more, but the keys points are that its growing exponentially, as more or less the same pace as the price of oil is increasing.

I downloaded the data into Excel from the Eirgrid site and the averages for January and February are:

Wind Generated: 265MW
System Demand: 3595MW

This gives 7.4% generated on average by wind. However, the problem is storage. Turlough Hill has a capacity of 1.6GWh. This means that it could produce 1.6GW for 1 hour (though its max generation capability is about one quarter of that, so it can run at max for around 4 hours, if full).

So, assuming that the wind generators are required to generate 200MW of power and have exclusive use of Turlough Hill for storage, I ran the numbers since January. Also I assumed that Turlough Hill was full initially.

Anyway, the reliability for different demands:

200MW: 63%
150MW: 78%
100MW: 95%

So, including full use of Turlough Hill, the current wind farm system could achieve 95% reliability if demand was 100MW.

Thus, it can produce 2.8% of demand with 95% reliability. Even that level of reliability would not really be acceptable.

We should really move all these posts into the SoI thread.
However, it's all valid stuff.

Ivnryn, as a matter of interest, were any of the maximum wind generation figures achieved during peak demand times? i.e. what were the maximum wind generation figures between, say, 3pm and 10pm for the last couple of months?
Or better still, what were the average wind generation figures for those times?

Ok, I re-ran it and set demand equal to a percentage of actual demand data. It doesn't really change things much.

Reliability for various percentages of demand provided by wind.
1% (~35MW): 100%
2% (~65MW): 99%
3% (~100MW): 93%
5% (~175MW): 69%
10% (~350MW): 41%

Note: Wind provides on average 265MW of power. However, even if it only provides on average half of that power, it is only 85% reliable.

I had a look at the data. The demand is lowest at around 6am with around 2.7GW and highest at 6pm with 4.5GW.

The wind data appears pretty flat and there is no time of the day that it peaks or falls.

...Depopulate the country by making it too expensive for those who can no longer afford to keep themselves warm in the winter.

From May 1st 2010 – the new carbon tax will result in a price increase of Kerosene (Heating Oil) by 4.3 cent a litre including VAT. This will mean an extra €43 Euro on 1000 litres – which is an increase of about 6.5%

Eamo has been badly exposed in government as simply a noisy wall of empty platitudes - I wouldn't be surprised if he tried to join FF soon aka Martin Cullen - the rat that jumped from the sinking ship that was the PDs.

LOL

And Im being selective. I just used the last 4 days

You hand picked 3 days with some of the highest wind output this year...

But lets take one of your days and look a bit closer

march 2nd wind supply peaked at 9pm at roughly 580MW.

Demand at that time roughly 4,100 MW

so roughly 15% at peak output

But lets look at 9am supply was roughly 260MW but demand was 3821MW so about 6%

So claiming we generate 15% of our electricity from wind is stretching things a bit.
