I just had a look at your upload and what I can tell from the abstract is that this is about both the infrastructure and the flows. Therefore, you were right to tag the ones that you used. In addition, I'd also tag "4.06. Flows: Consumption" and possibly "4.14. Flows: Imports and exports", depending on where the flows are coming from or going to.
On another note, I saw that the publication is in French and that you also copied the abstract in French. As you choose French as the language that it is in, you may have noticed that two additional fields opened up 1) for the title in original language and 2) abstract in original language. For future publication uploads, I'd like to ask you to fill in those fields and translate the title and abstract with google translate and put those in the respective English fields. I will make sure that from our side these things a properly marked and functional. This way, we can display the English abstracts, for the English-speakers to understand.
