Line 598:
Consequently, it is technically the the case that intermittency even with 100% wind is not a serious technical issue for the UK even with things as they stand at the moment.
That’s not to say that close to 100% is the most desirable economic course – that remains to be settled by proper detailed half hour by half studies. However the above simply broad analysis does how that it is likley to be perfecly technicall possilbe AS
1. In the UK there are already 5 Gw of existing switchable in real time storage heaters which can be set for freqeuecny control to deal with clearly up to 5 GW of variation, and to store power for many hours. Since these only cover about 1/5th of the UK housing stock these can be readilly exteneded.
▲But then one has to mention all the other already existing technologies than can be readily deployed to assist a 100% wind scenario;
3. there is the existing 2 GW cross channel link to Europe
4. There is the potential to add 6 GW at a cost of about £1billion 5. or 40 GW at say £7billion
5. Sinden's paper shows that it is rare that there are high winds simaltanoulsy over the whole of the UK meaning it would be relativley rare for the output of 140 GW of 35,000 turbines to exceed 100 Gw, meaing that virtually all power could be exported at that time - at which it has zero marginal cost, and can then be bouaght back as needed - from whoever on the continent can offer the lowest price - as there will alwasy be someone in the same position as us.
So it seems to me there is no doubt that the issue of intermittency does not stand in the way of 100% wind on the UK and any other large interconnected grid system.
