Several years ago I had a low income housing facility that wanted to consolidate two buildings with four apartments each plus a house meter on each to just one meter so they would only receive one electric bill instead of ten bills. Tenants did not pay electric bills the owner did.
Each building was served with 200 amp service conductor, which after doing some load calculations maybe should have been a little larger, but I'd almost bet the real demand was still under 200. The POCO engineer involved on this one wanted an 800 amp meter socket installed, two four inch conduits plus two spare four inch conduits between the meter and the pole. His justification was there were 4 100 amp main breakers supplied by a 200 amp conductor - plus a house main that he for some reason didn't include with his line of logic.
Keep in mind this install was already about 25-30 years old at the time, the apartments were all electric but showed no signs it was undersized. It was 120/240 single phase and only supplied with 37.5 or maybe 50 kVA transformer. Couldn't convince him the fact all this was well under size of what he wanted already and lasted as long as it had is a pretty good sign the load just isn't there.
On top of that the meters were indoors in the mechanical area, something that POCO no longer allowed for new installs, so you would think they would like to have gotten them out of there, but I think he was looking at no real change in average consumption but a loss of monthly minimum charges on 9 meters.
Most any other POCO in the region would have just put a CT meter at their pole, slugged the meters in the meter center and left everything else as is - which would have left me pretty much out of the picture altogether, but still was best interest for the customer.
