Theoretically optimal location of a distribution substation

Former Community Member

Hello, 
I have the following problem with the preliminary design stage of a residential area:

The software I use can calculate a theoretically optimal location of a distribution substation for low-voltage networks. This place is calculated as a "center of power demand" or "center of gravity" of electrical consumers.

If the substation locates in this optimal place, we can design 0.4kV distribution feeders with a minimum length and power losses in low-voltage feeders are minimal. 

I understand it’s almost impossible to put it exactly there, and I consider some sites nearby. But the architect believes that this is unacceptable in terms of landscape design and wants to place the substation in a far corner.

Who should be the arbiter in this situation?  DNO representative takes a neutral position.  Local authorities are completely on architect side, they do not care that long power cables will heat the atmosphere for many years to come.

    It is usual practice to run the cables along the sides of the roads rather than crossing land that may become other people’s property requiring lots of legal work writing wayleaves.


    Sometime in the UK it is virtually impossible to avoid crossing other people’s land as many housing estates are built with shared driveways. The water company sells an insurance to cover your private supply pipe, most people don’t bother paying for it, but as one guy said “When three of your neighbours drives have to be dug up and relayed in addition to your own if the pipework needs replacing, the insurance premium doesn’t seem to be so expensive “.
