[Tagging] Feature Proposal - RFC - Substation Refinement

I have a practical case at hand where an energy specialist in one international development institution is thrilled about the possibility of OSM providing a platform where "all" the details of the electricity network of one developing country. Something that no one has been able to do because different stakeholders can't come to an agreement who would be the guardians of such data (and share it to others). .. Which is why nobody really knows how much of the country is electrified (given the fragmented nature of the country and various development programs in it).
This is not (yet) an existing in the db case but I'll be exploring with him the possibility in the next half year--year. And while I'm not sure if they'd ever need all the details that are on the table now it's been clear that the people I've talked with about this have been very happy with the basic idea of OSM being "welcoming" to all verifiable objects that exist in the real world.

Whether such detailed mapping is useful only time can tell but there are
certainly mappers who want to add such information. From Taginfo:
power=busbar (13795), power=switch (8591), power=transformer (8958) to
mention the most frequently used substation component tags.
With this proposal I have tried to define the granularity at which
substations should be mapped. For example busbars and bays should be
mapped at the circuit level, not as individual conductors. With the
exception of power=switch (because it is so popular) it is recommended
not to map bay components (disconnectors, instrument transformers, surge
arresters etc) or other fine details.
