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

    . . . These figures have been pared to the absolute minimum, and I assume that load shedding will become common. . . 


    Oh dear. The OP has discovered a set of figures and put them here without a clue what they mean. These figures are for “DNO diversity” in working out cable sizes and substations for a housing estate. Applying these numbers in the “DNO world” gives a fairly good idea of how the load of a distribution feeder or substation will behave, and are the result of many years experience. I don’t believe anyone on here is daft enough to apply for a new supply of 5KVA and risk getting a 30A cutout fuse. 


    To recap, part or all of a housing estate, probably. A single dwelling, no. 


    Regards,

    Hi Alan


    I am aware these figures are to do with housing blocks and estates - my question is that the figures here seem lower than what I have seen applied to such developments before.


    I normally see a block/estate estimated at 5kVA per all electric flat (for around 50 to 100 plots) to work out the supply needed. That is what is getting put on the DNO application.


    2kVA as per those figures is a fair drop from that hence the question.


    Is 5kVA per unit considered overkill for even the smaller scale housing blocks of 50 to a hundred now (noting that the figures given stated up to 750 flats for the 2kVA allowance)?

    The figures aren’t too far away from what we use (a DNO). When replacing LV network fuses I usually find a pickup of 2KVA per property is a pretty good estimate, although the initial pickup will be a lot higher. 


    Regards,


    Alan.
