I agree the word is substation, but sadly there are 75,700+ entries for 
sub_station and only 18 entries for substation. I think the biggest 
confusion has been that a substation (sub_station) has something to do 
with power generation which it doesn't, only the conversion of voltages, 
connections between lines etc.

The good method for migrating is the one used to change highway=gate 
into barrier=gate by adding the new tag and leaving the old for a long 
changeover time, thus not breaking any data consumers uses. I don't 
think that would work well for this subtle change as many would not know 
which tag was right. A mass edit changeover to substation would break a 
lot of renders etc, so I suspect we are stuck with sub_station for now.
