IDNO Loads

HI All

Just come across the attached - a snippet from an IDNO's documentation about loads for residentials.

Loads a lot lower than I am used to - what are peoples thoughts on this?

I would not be comfortable going down that low - e.g. an all electric flat with panel rads and a 3kW cylinder - don't see how you could drop down so much.

i tend to see 4.5 to 5.5 kVA for all electric flats, lowerend being for single bed units and 5.5 for two bed

I agree - they take into account diversity across a large number of homes - they're no use at all for sizing an individual supply.

If you think about it the National Grid rarely generates more than 50GW - and as there are about 20 million homes - the average demand per home even during peak times can't be more than about 2.5kW - and probably a lot less than that as industry and commerce will be drawing a not insignificant amount.
