New wind record?

[dan_b]

The wind needle is definitely hard up against the rev limiter again isn't it - seems to sit there at 22GW for quite extended periods.

Another wind record notification from NESO this morning: 22.523 GW on 18 December 2024.

Impressive - especially when at a time of low overnight demand -

Was apparently 68% of all demand at the time

This is also impressive
"renewables have generated over 50% of Britain’s electricity for the last four consecutive quarters for the first time (Q4 2023 to Q3 2024)."
Although I suspect Drax and its wood burning stoves are probably factored into that.

I'm actually pretty disappointed that wind power will only average about 9.4GW this year, up from 8.8GW two years ago. That's fairly paltry growth, and surely wind power capacity has grown by a lot more than that.

I assume curtailment has a lot to answer for. Luckily other trends have been positive, such that fossil fuel generation is down sharply (largely transfers), but we still need much faster growth than this...

For 9 hrs overnight we have been net zero where exports were greater than our use of gas.

This happened whilst curtailing wind by 4 GWh +

Yesterday set new record ? for wind curtailment peaking at close to 6GW AND for the day wind curtailment for the 24hrs was 113GWh when gas only produced 92GWh

Thanks Ken, that's some nice numbers / data to put a smile on my face this morning.

New thought for me, is or will solar pv curtailment be a thing in large scale projects in UK?

My mind is now very much into generate at point of use, get everything you can out of it and export the remaining generation. Full control in your own hands with no excuses to success. Unless we go towards the European pv curtailment model in the coming years.

Then it's use on site or give to neighbours.

Sorry, not meant as a hijack but RE being RE and curtailment being an issue across both PV & WT, i wonder if they knock off hydroturbines too?

Utility solar already is self curtailed when the wholesale price goes negative because CfD does not pay out when prices go negative.

What you suggest of maximising self use has been the mantra since all this household pv started.

However i would suggest that we now consider, because of reduced prices of equipment, turning this on its head with the advent of EVs, HPs, Batts etc and concentrate on exporting as much PV as possible at 15p/kwh and importing as much at 7p/kwh.

I maintain that if individually we have PV that produced annually as much as the total leccy bill (including EV and HP) and add a 8kwh? batt then we could end up with no leccy bill other than the standing charge.

IE
Household consumption per year
EV -2000kwh
HP- 3500kwh (national avg gas 11500kwh/ COP of 3 for HP)
House -3600kwh (national avg)
Total c 9,000kwh/yr
Assume we have a 9 kw PV and one can export 8000 kwh/yr at 15p/kwh = £1200/yr

So assuming TOU tariff 7p and 23p
So 50% import at night at 7p/kwh = 9000/2 x 7p = £315
40% import at 23p/kwh = 40% x 9000 x 23p = £828/yr
10% solar at zero.

So total import cost £1143 whilst earning £1200 - whats not to like.

Dont think i am going mad.

Looks good, are the figures pretty close to your annual?

Yes to pv use mantra but I'm emphasising "Full control in your own hands with no excuses to success." That is as equally appealing to me as the finances.
