Dear All

 

Over the past few days grid connected  wind in the UK has increased from 4351 MW to 4491 MW.

 

The increase in wind power is not prevented some very low wind periods recently. It dropped to 92 MW on 12th April at 9.00am. A similar drop occurred about a fortnight earlier. In other words on the basis of capacity wind requires  98-99% "back up" from some other power source. If one works on the assumption that peak wind output is about 80% of capacity in Britain (in Spain it seems to be about 70%), this still means that the back up is extremely high. 

 

As I keep pointing out, elaborate least squares approaches to  calculating how much back up is needed are a waste of time.

 

What is not a problem is compensating for the daily changes in output
