Great! I just merged the new scenario management, which has quite some changes and this branch needs to be adjusted to that. Otherwise the changes look good!

What you'd need to do is to mirror the following lines of code:

pypsa-eur/rules/build_electricity.smk

Lines 387 to 391 in 66d078e

	def input_profile_tech(w):
	return {
	f"profile_{tech}": resources(f"profile_{tech}.nc")
	for tech in config_provider("electricity", "renewable_carriers")(w)
	}

then

pypsa-eur/rules/build_electricity.smk

Lines 413 to 415 in 66d078e

	input:
	unpack(input_profile_tech),
	unpack(input_conventional),

The unpack() function allows the use of the wildcard-aware config_provider().

Okay thanks, I'll get around to it shortly!

Alright the first time I didn't test well enough but this time it should all work. I have it from good sources that this will make fellow energy system modellers in Austria quite happy!
