Hi @euronion :)
are you able to review this. I would need it for this PR: pypsa-meets-earth/pypsa-earth#1858
Thanks a lot.

Thanks for the contribution, see the comments below and let me know if you have any question!

* The "currency_year" column will now reflect the inflation adjusted currency year instead of the original currency year of the input data. (https://github.com/PyPSA/technology-data/pull/275)

* Insert costs for water networks (https://github.com/PyPSA/technology-data/pull/277)

Suggested change
* Insert costs for water networks (https://github.com/PyPSA/technology-data/pull/277)
* Add cost assumptions for water network infrastructure: water pipeline HDPE and water pipeline booster pump (https://github.com/PyPSA/technology-data/pull/277)

That makes it clearer what technologies have been added

  • Please rename it to "water pipeline HDPE", i.e. that the name reflects broader category -> diameter -> material details. So some of the info that you put in the details should also go into the name

  • Can you add the figure where you extracted the data from in the report? (Probably figure 4-7?) and the date when you accessed the publication.

  • The currency year should be 2022 instead of 2023, can you confirm/check?

  • Are there any insights about the technology year of this data, whether this is from 1981 (like the pump station data)? Else we can keep it as 2023

Similar points as for the technology above:

  • rename to something like "water pipeline booster pump"
  • Exact location where the info is taken from the publication (I couldn't locate the origin of the data from the pub)
  • It seems like the publication uses a formula with a scaling exponent != 1, so if you make an assumption on the HP of the pump, add this assumptions and ideally also the calculation to the details.
  • Check technology (1981?) and currency year (2022)

Efficiency is not clear for this technology.

Minimum: Add to the details what the efficiency unit is
Ideally: Change the unit to something more clear, maybe m3 water per kWh or something?
