Petrol stations have various strict requirements regarding their electrical installations for obvious reasons. How will adding a MW size supply for a few high power chargers be dealt with, separation? Will earth leakage currents be a problem? If I remember correctly the reason the canopys are so high is to move the lighting into a different zone.
In a conversation this evening with an ex DNO guy who's now HV freelance, the subject of EV came up and it would appear that the UK is following the Dutch way of the DNO providing a 3-phase cut-out to all new build (WPD are now implementing this where there is 3-wire 11 kV). The idea being is that one of the phases is for the standard domestic CU and if an EV charge point is required, it uses one or possibly two of the remaining phases and dedicated "CU" or "switch-fuse" with a bi-directional meter so that the vehicle battery can be used for peak lopping.
It still doesn't resolve the problem of base load increasing faster than generating capacity though.......
