How to map partly-abandoned power plant

I just created this changeset, hoping to capture the situation of a partly abandoned power plant. And I would like to ask if some of my tagging decisions are correct.

The power plant is a combination of four wind power plants and pumped hydro. The wind power plants are operational since 2017. The pumped hydro consists of a reservoir at the bottom of a hill and three smaller reservoirs at three of the wind power plants. This pumped hydro component was under construction, but construction has now been abandoned due to economical reasons. See my changeset sources for articles about that.

I made the following decisions:

  • Marked the upper water reservoirs (building=water_storage) as abandoned=yes because they are still visible, but cannot easily be used to store water anymore.
  • Similarly, marked the service building as abandoned=yes, but now that I think about it disused=yes is probably better suited?
  • Marked the pipeline as abandoned:man_made=pipeline, but still kept e.g. location=underground. I followed the comment by @dieterdreist in this thread saying an abandoned pipeline cannot really be said to be a pipeline anymore.
  • Marked the generators as abandoned:generator… for the same reason.
  • Added a description to the relation. Used abandoned:generator, abandoned:storage and abandoned:penstock as the roles of the abandoned components of the relation.
  • Changed tags on the relation like construction:plant:source=wind;hydro to abandoned:plant:source=wind;hydro.

I find it a little strange to use abandoned for features that have never been operational. Is that alright to do? Or should we just delete all the pumped hydro components from the map?

I appreciate your input!

This looks completely reasonable to me!

Even in common usage of the word, one can “abandon” an unfinished project.
