The substation refinement proposal has been approved by a large majority of voters. The new feature page can be found here http://wiki.openstreetmap.org/wiki/Tag:power%3Dsubstation
Afterwards I regret a bit that I didn't reserve a dedicated value in the substation=* tag for the small street level substations (Trafohäuschen in German). I used the IEC definitions that suggest that anything below 100 kV or so should be considered 'distribution'. It may have been better to define this value only to cover the last level of transformation from medium voltage to low voltage supplied to household customers. This would address the concerns of some mappers, especially in central Europe, that used the old "station" vs "sub_station" to distinguish this. I propose to change the meaning of "substation=distribution" to be used only on substations at the last level of voltage transforming, thus the small street-level transformer kiosks etc supplied with medium voltage (typically 10-30 kV) and delivering low voltage power to households and small businesses. A small substation would then be tagged as power=substation and substation=distribution. Mappers could then unambiguously tag such facilities without having to know the actual voltage(s) employed in a given area. Tagging the voltage is still recommended, though. I would like to have opinions on this. If this change is made some substations at the 'second level' such as 60/10 kV now tagged as 'distribution' should have this tag removed. The current suggestion that small kiosk substations may be tagged as 'power=transformer' will then be removed to avoid any confusion. Only pole mounted transformers will keep their own tagging scheme (power=pole, transformer=yes/distribution).
