An increase in electricity demand?

"Electric heaters and cookers were being offered to elderly or sick customers, and those with young children."


Certainly if we lost our gas supply, whilst we aleady cook electric, our heating is gas fired CH. To maintain comfort levels I could see three or four 2 kW fan heaters being utilised for much of the day. As for domestic water heating, a kettle or two. 


I seem to remember a previous gas problem where the local gas supplier took round electric heaters to affected houses and blew a few main fuses....???


The photograph of the SGN vehicle with a sat dish and two air conditioners has me wondering. If the a/c units are to get rid of excessive heat build up, then besides the load of the TWO a/c compressors, I wonder what they have in the van - besides a rather large gene??

    Yes, I expect a significant increase in load and some local power cuts as a result of this gas supply failure.

    The DNOs only allow ABOUT 5 amps or ABOUT 1Kva per home that has a gas supply. This rather inadequate sounding figure has in fact a good record under normal conditions.


    However under present conditions with cold weather and no gas supply over a significant area, I foresee problems. If each home adds on average an extra 2Kw of space heating, then the total load is TREBELED !

    I hope that someone has ordered some large generators. And thought about how and where to connect these. Connecting a generator to the LV busbars in a substation will relieve the load on the transformer, but wont help the LV mains leaving the substation.

    So far as possible, generators need to be connected at or near the far end of LV street mains, in order that the cable loading may be reduced. In many cases LV mains from different substations can be interconnected via link boxes set in the pavement. One approach is to link together two substations via a link box AND connect a large generator to the link box.

    This means that the main is being fed from both ends.

    Generators used thus must of course be suitable for synchronising with the public supply, but most large transportable ones are so designed.
