Spiritofireland.org - suggests energy independence in five years and much more

Then you have two options:

1. You can falsify this finding by using the source data for electricity demand and wind farm output yourself. It can be found here: System Performance Data | Eirgrid
   
2. Or you can keep sticking your fingers in your ears and go "nyah nyah nyah nyah nyah"

Your choice.

Put up or shut up.

I feel aggrieved. You responded to his post and not to mine.

[Geckko]

But the proposal comes complete with interconnection and asks the population what level of independence is do they want, Phase two of S of I will include wave and tidal as they become available and once phase one is complete I can see off-shore wind commercially (to the consumer) viable.
I would not want to have to go back to deciphering handwriting even your own artistic style

Excellent.

So we spend how much building 10GW of windfarm capacity and 500GW of pumped storage capacity and we STILL need 100% backup which we buy in from somewhere.

This clearly displays that even this hypothetically massive investment would provide zero "energy independence" (nothwitshtanding that we have already discussed how nonsensical that concept is).

No, it still doesn't make any sense. According to this, expected daily peak demand is less than 4GW, usually closer to 3GW. And thats peak demand, giving the reservoirs ample time to refill at offpeak hours, since the wind doesn't stop blowing at night. And lest we forget, this capacity is in addition to the CDGUs in place already. Hell, even the interconnector would be enough to take up any slack by itself.

Eh no, your graph is wrong.

1 Ever used an overdraft facility in a bank, preferably with an account that pays interest when you are in the black

2 Every energy system includes back up, why do you think the ESB uses different fuels for its plant

3 The eirgrid figures will improve a lot, in the future of putting wind turbines where they work best and most efficiently, not where the grid can connect to them

If I were to propose to you a project, similar to S of I, but with one difference.
It would state that energy 50% energy independence, could be achieved in the first phase, and that this could be improved on in the second phase, up to a limit decided by the energy policy of Ireland.

How would you view it.?

You pillock. Even during offpeak hours 10GW ofnwindfarm capacity, would still not be meeting demand for large chunk of the last 15 days. That is what my chart shows. For only one day was there any excess supply available to divert to storage.

Go and get the data!!!!! Look, here is the graph for yesterday, the ACTUAL DATA is available there. Demand at 15 intervals! Demand hits a low of just under 2GW on weekdays this time of year - the data is there!!!!!.



Wind output is available there too, at 15 minute intervals.

Run the numbers. The graph might be wrong, but you have not proven so. Do some proper analysis.

[Geckko]

And just to be clear. I have been scrupulously fair in constructing that analysis, by excluding:

Loss that would occur when electricity is diverted from grid to storage and the then back from storage to grid.

Downtime for maintenance of wind turbines and hydro turbines.

The response time of the backup pumped storage. My analysis use 15 minutes instant response to take electricty from the grid and store it (at 100% efficiency) and similarly 15 minutes to revert to generation (again at 100% efficiency). The times I have seen ar more like 1 hour.

[fiannafailure]

And there was me trying to be nice to you, I will let Dios answer for himself, but in my opinion you cannot do an a math problem without including accurate figures for all terms, you then extrapolate in to the future based on your research

Put it this way. I you proposed building 10GW of windfarm cpaacity and linking it to 500GW hours of pumped hydro storage you would not be able to take offline any of the current generating capacity, because it would still be needed (as my analysis shows).

So I would view that as a collosal waste of money - you would have this massive new infrastructure completely overlayed on the current one - redundant from the outset. This shouldn't suprise you because this is exactly the experience of Denmark.

Now, I don't care if you waste your money. My concern is that you want to waste my money.
