Are these variables really necessary? A gas turbine will always be used with Natural Gas, not other Fossil Fuels... Also, it is confusing that the other types of gas power plants are not listed here. So better to remove.

Hi Again Daniel. Thank you for your comments. The point is that the gas turbine units do not use natural gas as the fuel necessarily. The term "gas" in a gas turbine refers to the working fluid used to drive the turbine, similar to how steam is used in steam turbines.

Fair enough (I meant that oil-based gas turbines are probably not really used any more, right?).

But that still doesn't mean that we need a part-aggregate "Fossil". After all, you could also run it with Hydrogen, which could or could not be from fossil sources...

OK. Sorry for the misunderstanding on my part.
However, in our dataset, we still have a considerable installed capacity of gas turbine units using various primary fuels, so I had to include all of them.

Regarding "Fossil," I used this term to classify the diesel generation units in my dataset because "Diesel" was not listed as a separate category in the common nomenclature.

You could simplify this file by using a tag-list, so creating a separate file tag_power_turbine_types.yaml (or similar) that has

- Turbine Type:
    - Combined Cycle:
        description: combined-cycle (CC)
    - Gas Turbine:
         description: gas turbines (GT)
    - Integrated Gasification Combined-Cycle:
        description: integrated gasification combined cycle plants (IGCC)
    - Steam Turbine:
        description: steam turbines

And then simplify this section

Suggested change
- Capacity|Electricity|Gas|Combined Cycle:
description: Installed (available) capacity to generate electricity from natural gas combined cycle plants
unit: GW
- Capacity|Electricity|Gas|Gas Turbine:
description: Installed (available) capacity to generate electricity from natural gas gas turbines
unit: GW
- Capacity|Electricity|Gas|Integrated Gasification Combined Cycle:
description: Installed (available) capacity to generate electricity from integrated gasification combined cycle plants
unit: GW
- Capacity|Electricity|Gas|Steam Turbine:
description: Installed (available) capacity to generate electricity from natural gas steam turbines
unit: GW
- Capacity|Electricity|Gas|{Turbine Type}:
description: Installed (available) capacity to generate electricity with natural gas
using {Turbine Type} plants
unit: GW

Same for all other variables that use all combinations of turbines.

This produces a much more concise and readable variable list file. The nomenclature package will automatically create all permutations during scenario validation.

Nice. I will do it.

Is this really a thing?

Yes. These units utilize sunlight to heat fluids, generating steam to drive turbines and produce electricity. Spain, particularly, has a considerable installed capacity of this type.

Still, if you think adding a new technology like this might be challenging for the nomenclature used throughout the whole project, I can omit it and categorize those units simply as solar units.

Ok, is that the same as Concentrated Solar Power (CSP)? If yes, I suggest to use CSP to remain consistent with common-definitions.

There, we use "Final Energy|Solar" for thermal heat, but for water-heating, see here

You are right. Thanks for pointing it out.
I removed Capacity|Electricity|Solar|Thermal and replaced Thermal with CSP for Marginal Cost|Electricity|Solar|CSP.
