build_renewable_profiles fails for landlocked countries due to offwind targets

[Gre-Dog]

Hi PyPSA-Earth team,

I'm running a minimal simulation for Jordan, a landlocked country (countries: ["JO"]), using the following config.yaml (v0.6.0):

renewables:
technologies:
onwind: true
pv: true
hydro: true
offwind-ac: false
offwind-dc: false

Despite explicitly disabling both offwind-ac and offwind-dc, snakemake still tries to build:

resources/renewable_profiles/profile_offwind-ac.nc

resources/renewable_profiles/profile_offwind-dc.nc

This leads to a failure in build_renewable_profiles because no valid offshore regions exist in the spatial inputs (as expected for a landlocked country).

Observed behavior:

MissingInputException in rule add_electricity:
Missing input files: profile_offwind-ac.nc, profile_offwind-dc.nc

Root cause:

build_renewable_profiles runs for all entries in config["renewable"], even if the technology is set to false and/or not applicable (e.g., no offshore areas in regions_offshore.geojson).

Downstream rule add_electricity expects all profile_*.nc files, even if the technology is irrelevant to the selected country.

Expected behavior:

For landlocked countries, offwind profiles should be excluded entirely from the DAG.

Rules like add_electricity should only depend on renewable technologies that are both enabled and spatially valid.

Potential workaround:

One can patch the rule with:

wildcard_constraints:
technology="onwind|pv|hydro"

…but this only pushes the error to add_electricity, which still looks for missing offwind profiles.

Let me know if you have some ideas.

Thanks for your work on this great tool!

Hello @Gre-Dog, and thank you for letting know.
To get rid of offshore technologies you need to modify this line

pypsa-earth/config.default.yaml

Lines 174 to 175 in b919f01

	extendable_carriers:
	Generator: [solar, onwind, offwind-ac, offwind-dc, OCGT]

That needs probably to be documented better. Feel free to open a PR to address this point in the documentation
