Some years ago, I heard that the really big load was due substantially to water pumping stations coping with the huge number of WC flushes rather than the kettles.
Never seen it verified, though.

But the sums indicate they've used peak windmill output versus average house consumption - so its miles out for that reason.
Err, I don't think so. It is the admd x number of dwellings that gives the maximum demand on the network, or every planning rule in the book might as well be abandoned

I'd have thought your method would seriously underestimate demand at peak - say breakfast and tea times?
It really depends what you're planning. Road network design can use average flow figures at the cost of occasional jams. Electricity is rather different.

One of the reasons I don't have a telly.
ISTM that the TV schedulers are lining up advert breaks to counter
*channel hoppers*. >
Been like this at least 10 years (since we had cable). Ads come on one channel - you start going up and down the channels to see ads on all the other channels. Although since the TiVo (and latterly the V+ box) we rarely see adverts ;)
And the same applies with any generation scheme. The same solution apply.

It was predicted as an ice age about 30 years ago. So global warming is obviously the saviour of us all. Bring it on, I say.

Aye, but there's quite a body of knowledge that's gone into system planning . For instance, cables and transformers are quite capable of withstanding p eriods of cyclic overload without distress. The key word is cyclic, which a llows both conductors and insulation materials to return to their design sp ec

It is important for the rating of electrical equipment. The load can be expressed as an rms value but the key thing is to understand the thermal time constants for the kit you are using.
I have been involved with a number of railway rolling stock applications where we were able to avoid fan cooling some seriously large power semiconductors (which brings with it lots of maintenance complications) by using massive cast aluminium heat sinks, with their fins in the natural airflow around the vehicle. The load was very intermittent, only being high whilst the train accelerated.

Yes, you obviously have specialist knowledge, as do I. The point I was maki ng, a little knowledge is dangerous!

average demand x number of dwellings gives average demand, not peak.

Except admd means after diversity maximum demand, not average demand. A little knowledge is dangerous.....
