I asked NG for a dump of frequency deviations from the nominal 50Hz for a month at 1-minute sampling intervals so I could analyse what sort of dynamic-demand responses should be triggered when (I got the whole of August), and I also asked NG for the frequency data around the time when one of the UK's biggest generators (Sizewell) tripped off unexpectedly and NG supplied that too.

So this afternoon I have a little number-crunching to do.  I'm not any sort of statistician other than ropey/amateur, but I think that even my mediocre skills should be able extract gold from the nicely-prepared data that NG supplied.

For the record it's now publicly available in the XLS spreadsheets linked to from about the third-last bullet in my 'Sources' section, should one of you be mad for it!  B^>

So, thank you NG!
