Wind energy electricity generation record yesterday

probe

Ireland's wind farms were churning out 770 MW per hr around 23h00 yesterday (2008.09.10). Either the wind was blowing at the right speed in all the right places or someone has put up an illegal wind farm on the grid recently!

Is that what we max out at?
What were our requirements at the time?

Total requirements at 23h00 on that day 3103 MW.

The record for the 10th is what IRL has maxed out at so far in terms of wind electricity generation ever.

The sky is the limit of course, if the CER would stop holding developments up!

The "hold up" with wind has never been about the maximum it can generate. Its about the variability. There have been times (within 48 hours of your new record, in fact) where generation of wind fell to just over 2% of that record. The average over the last 100 days is less then 30% of that record.

So let's take it that the average yield is 30% for the sake of argument. 7.2 GW of capacity would on average yield 2.16 GW. This is about half the country's total average electricity demand. The existing installed base of generating capacity is not going to be trashed overnight.

The powers that be have been sitting on international grid connection matters for the past decade (polite mode = "on"). Wind energy is a natural resource, and every day that the exploitation of this resource is delayed is criminal waste of this national resource. Over €1bn a year lost to the economy on this item alone. Blocked by bureaucratic ossification!

I lioke the numbers

However the ~770 produced compared to ~3100 demanded would infer the peak ability now is 25% of capisity

This infers with the the 30% rule you saying is 25/3= ~8% of the electricity is now made from wind farms

so where does the 13% figures banded around from come

I say roll on 7.2GW ASAP and give us at least 50%

In excess times we can sell the power through interconectors or use the power to produce other energy sources like H2O2 hydrogen peroxide to make guick ramp hydrogen peroxide steam generators that kick in with low wind power outputs

Yup. And if we assume a typical generation capability of 5MW per turbine, we'll only need 1440 turbines to do that. Of course, when we hit those troughs, where we're producing about 2% of capacity, those 1440 turbines will produce a whopping 144MW.

Now, given that we're talking about averages here, the reality will be that other than (limited) storage capability, we'll have a net balancing out of imports vs exports, so the notion that we can export wind when we have a surplus has to be counter-balanced by the requirement to import just about the same amount when the wind isn't blowing.

This is about half the country's total average electricity demand.

Half the country's current demand. You're a big supporter of weaning us off oil (which I understand) and tend to tout electricity from our abundant wind supplies as the alternative. So how many 5MW plants are we going to need for that vision? 3000? 5000? 10,000? And remember...the more power we consume based on wind, the more we need to be able to import on demand when the wind isn't blowing. Just how many GW of spare nuclear capacity do we want the French or English to have sitting waiting for us to want it? Will they play ball?

Don't get me wrong...I agree fully that Ireland should have more wind power than it currently does. However, its not just something they can give free reign to and ignore the reality that they still need the capability to replace virtually all of it from alternate sources.

The powers that be have been sitting on international grid connection matters for the past decade (polite mode = "on").

Ironically, one of the reasons they've been doing that is to allow the growth of indigenous generation industry. If they hadn't, then no-one could have built anything unless it was cheaper than importing from abroad. That alone would have been a death-knell for wind...although the cost-dynamics are slowly changing.

Over €1bn a year lost to the economy on this item alone.

As I've pointed out, this figure ignores the cost of importing shortfall when the wind isn't blowing...unless the idea was to continue to have Ireland produce 100% of its baseload from traditional, thermal generation, and to build an export-only wind market, assuming that whoever was at the other end of the interconnect would have bought the stuff at the price we would have been charging.

You've taken average wind capacity and compared to peak demand. Compare it to average demand and you'll have a higher figure.

WOW 770 MW

Just looked at the figures there.

Oh thanks that makes sensce

Roll on 50% cleaner greener wind power and simialr solutions and stop so much of Irish money flying the coop to somewhere else and give us more energy shock resistance at this the wrong end of the pipe line
