IDNO Loads

me1899
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

    In my view, diversity can not be applied to electric space heating within any one dwelling. On a cold day the occupiers might well turn it all on.

    Some diversity can however be applied over a large estate, some homes will be empty, either continually, or during the evening peak. Other homes will have been occupied all day, and therefore be up to temperature with most of the heaters turned off by thermostats or by hand.

    3kw is a fair bit of heat in a small and well insulated modern home, especially as it might be nearer 4kw after allowing for a few empty homes, and for a bit of overloading in cold weather.


    The price of the homes if compared to others in the same area is also IMO indirectly relevant. A relatively low purchase price implies relatively less well of customers who will tend to spend less on electricity.

    A higher price implies a potentially greater fuel use.


    Flats tend to use less per square meter than houses, due to less heat loss, and a lot less in absolute terms due to the smaller area.
