power=substation building=service should show name in substation style #2259

When there's a building that is an electricity substation, it's natural to tag it building=service (or building=yes) and power=substation. This causes the name of the building to be displayed in black upright text rather than in the purple oblique style that's usual for power=substation. This means that substations that are also buildings end up with a different tagging style from substations that are inside buildings (mapped as a point) or outdoor substations (which might contain buildings).

Substation that is a building (power=substation building=service name=North Residence): 172682

Substation (power=substation name=Institute of Astronomy) mapped as a point within a building (building=service ref=T035): 172671

Substation that is not a building (power=substation name=Cryogenics Sub Station): 172686

I think that the text of the first case should use the same style as the second case, while keeping the same style for the building outline. This would be consistent with the style where a shop and a building share the same way.

this is surely strange: a substation that is called "institute"???

I could imagine the energy supplier has put a label on the station, which entity it is associated to. Thus it is a label, not a name, such as a fuse in my fusebox is labelled Kitchen. That misuse of the name tag happens quite often, look at supermarket car parks.

It's not really relevant to this issue, but UK Power Networks (the company that runs all of those substations) seems to think that those are the names of the substations. See page 5 of this PDF file, where location labels (from which I transcribed the names) are shown as containing "SITE NAME" and "SITE NUMBER". I transcribed the site name into name and the site number into ref.

This feature is by no means unique to substations. Next to the North Residence substation you can see a bus stop with name=Cavendish Laboratory.

I second @bjh21 here Power operators, like any other utilities operators use to name their facilities according to which place they supply to or the place they are located in. Those names are clearly visible on the buildings, and it would be harder to use any other tag than name=* to suit the need to map it.
