I have now switched over the tagging and examples to the namespace based
tagging of grid and generator. Overall, this makes it easier and clearer
to tag backup generators and grid-connected houses with solar panels etc
IMO. Perhaps it would also be possible to then tag electricity:grid=yes
and electricity=no in the case of grid connected houses experiencing a
long-term power outage during a natural disaster?

The electricity tag isn't used a lot yet. I have no experience with
automated or semi-automated edits, but perhaps changing
electricity=none and electricity=grid to electricity:grid=yes would be
relatively straightforward? (This is unfortunately the problem with
people adding major undiscussed/proposed tags to the main wiki.
Especially power_supply is frustrating. )
What do others think about the tag options
electricity:grid=yes/no/backup
electricity:generator=yes/no/backup
electricity=yes
electricity=no
[electricity=yes would be used when grid or generator is unknown]
instead of
electricity=grid
electricity=generator
electricity=yes
electricity=no

Hi,
While the original proposal did specify that generators are
usually diesel, broadening the definition would only lead to a
loss of detail, but the tagging would still be correct. I'm
hesitant to use *offgrid* as a building that has, for example, a
grid connection with solar panels on the roof would then be
tagged as *electricity=grid;offgrid* instead of
*electricity=grid;generator*. The former is illogical.
However, I don't have any experience in developing countries: is
it easier to verify if something is off-grid compared to if it is
connected to a generator? And, would it be necessary to
differentiate between local grids (i.e. 2-3 generators, no
substations, transfromers, etc.) and national grids? Perhaps then
a network tag would be useful, i.e. network=national, local,
regional similar to the way cycle networks are mapped?
A further suggestion was to change the tagging
to***electricity:grid=yes/no/backup* and/or
*electricity:generator=yes/no/backup*. This might be less
ambiguous for tagging amenities or buildings that get electricity
from both sources and would then be more consistent with tagging
such as *electricity:generator:origin=diesel* when, e.g. a
building has a backup diesel generator but is connected to the
grid. Unfortunately, it would then not be consistent with the use
by the Healthsites Mapping Project, although this already has the
inconsistent *electricity=none* tag which should probably be
changed directly to *electricity=no.*
Here is the link to that suggestion I made
https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/electricity#multiple_values
<https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/electricity#multiple_values> and
https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/electricity#origin_of_different_sources
<https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/electricity#origin_of_different_sources>
The whole point of the proposal process is to identify these
potential issues, resolve them, and get community agreement. If the
goal is just to implement someone else's standard then we can't use
the wisdom of the community here to improve the tag, therefore I'm
not too fussed about making this match what another project is using,
instead we should aim to have the best tags and documentation as the
outcome of this proposal process. Then if that's different, other
projects closely tied to OSM can migrate to the OSM community
accepted schema.
