This raises another point I can illustrate with:
Allegedly, a service-station on the M3 motorway near London had or had its rank of chargers powered by its own diesel generator, housed in a separate building, allegedly because they were installed before the public supply to the property was made adequate.
However, we must be careful of report veracity...
1) Was it true and is it still true?
2) Was any such installation continuous or a reserve for power-cuts? Power cuts in any given area are relatively rare in the UK and usually last less than a few hours, though still inconvenient for BEV drivers in mid-journey.
3) Was / is the generator already there anyway, for the service-area generally?
4) Even if true and for continuously feeding the chargers, what of its location?
I think it is some 30 or 40 miles even from the M3 / M25 junction. Many of its customers would be commuters to and from the capital, or travelling to and from London's four airports. Though probably not to the several, main railway termini much nearer the city centre.
So would electric cars charged from a diesel-alternator set a good way from the edge of London, be less polluting overall and certainly so in the urban area, than the equivalent vehicles with Diesel engines?

@ArishMell It does actually make sense if you throw a battery into the loop... A diesel generator is far more efficient running under a constant, steady load and speed, than it is in traffic with variable spped and stop start. An electric motor is obviously cleaner in traffic, but also returns far more torque to the road when it is needed.. So a charging station calibrated to supply what the location required should be cleaner than the equivalent in diesel powered vehicles in normal city traffic.😷
