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.*
Cheers, Lukas

Hi all,
Thanks a lot Lukas for reworking this proposal.
I like Joseph's idea of *electricity=grid/offgrid/yes/no* if you're
introducing *electricity:origin=**.
I'd suggest dropping the generator value as it brings confusion and
can be difficult to verify. Originally electricity=generator seemed to
be intended for diesel devices, but I think we should use something
like electricity:origin=diesel for it instead.
@Volker, I understand the tag might be less relevant in developed
countries where it is normal to have electricity. But electricity
availability is an important information in many developing countries
(like mine) where most of the population is not connected to the
electricity grid. It would be useful for health facilities
and accommodation buildings... - See Healthsites' data model at
https://wiki.openstreetmap.org/wiki/Global_Healthsites_Mapping_Project
<https://wiki.openstreetmap.org/wiki/Global_Healthsites_Mapping_Project>
where the tag is used.
Good job, Lukas!

Since a lot of people apparently didnt see the RFC the first

The original message:
Hello all,
after the comments on the confusing nature of the word 'source'
in my original proposal of 'electricity:source', I have now
changed the name to 'electricity:origin' as suggested on the
discussion page. Furthermore, I would like to revive and extend
the proposal of the key 'electricity' as this previously
conflicted with parts of the electricity:source proposal and was
not consistent.
Both proposal pages:
[1]
https://wiki.openstreetmap.org/wiki/Proposed_features/electricity
<https://wiki.openstreetmap.org/wiki/Proposed_features/electricity>
[2]
https://wiki.openstreetmap.org/w/index.php?title=Proposed_features/electricity:source
<https://wiki.openstreetmap.org/w/index.php?title=Proposed_features/electricity:source>
The idea now is to allow for the tagging of buildings or
amenities that have electricity. The rationale is described in
more detail at [1]. Tags such as access, fee, schedule and origin
can then narrow down the availability to the public and the
question of financial or direct origin of the electricity.
This is distinct from the drafted tag power_supply as it is used
to describe the type of sockets used at a specific outlet. The
values for that tag are still currently under discussion.
I would also not tag this as a subset of power=* as this maps the
facilities and features that relate to the generation and
distribution of electrical power and should not be used to map
the consumers of electricity.
I am eager to hear the feedback to the revised proposals!
-----------------------------------------------------------------------------------------------------------
Also, perhaps relevant: both the power_supply
<https://wiki.openstreetmap.org/wiki/Key:power_supply> and socket
<https://wiki.openstreetmap.org/wiki/Key:socket> keys describe
the same feature. power_supply so far has occasionally been used
in the manner that electricity proposes to be. Unfortunately, the
proposal for power_supply is relatively inconsistent. I think the
socket:* tag is better thought out and also currently more used.
I would be in favor of deprecating power_supply and separating
the two meanings it currently has into electricity=* and socket:*=#.
Regards,
Lukas
