I just suggested the Gold Coast complex near Castle Peak Bay on Castle Peak Road.
Are you living close to that, CCT? They already have a few charging stations in the shopping mall parking lot in the basement (13A only I think).
It would be a great spot for me, as I am close to it. And a lot of traffic goes that way. When the tunnel opens between Tuen Mun and the airport/Tung Chung, and the passage to the North towards Yuen Long, then it will be even better to have a supercharger here. One could be concerned is that Castle Peak Road along this stretch is quite overloaded, but it won't be that many extra cars I think. When there are special happenings, like recently at Easter, it's totally jammed by cars trying to get in and out at the same time. They need to make one more exit, maybe even a traffic light. In fact, there is a traffic light close by, they could make the exit there, and combine it with a supercharger.
For that area, it would cover quite a bit, and there is definitely room in the front to install quite a few spots. A great "Green PR" initiative for the "Gold Coast Piazza"
They already have a deal with 2 hour free parking if shopping more than 100 HKD, 3 hours if shopping more than 200 HKD:
Gold Coast Piazza
Just add free electric charge to that also ...

Just made some sketches on a Google Map, for two possible locations of superchargers in Gold Coast. One is in front of the shopping mall, the other one on the auxillary overflow parking lot inside the Gold Coast Yacht and Country Club.
In either case, I think there should be a separate access, and one in conjunction with the already existing traffic light could be a good suggestion (to avoid congestion on busy days). I am sure there are lots of obstacles wrt ownership of land, road regulations, electric cabling and much more!
