Thank you all for your time and wisdom!

Yes, you have a point. Mea culpa. (But I still reckon the English is pretty dodgy ...)

That's really a technical question outside the scope of this forum about terminology — you ought to research the tax regulations in the relevant country (which you haven't told us about!)

My totally non-expert guess would be, from a purely linguistic standpoint, that a tax is levied on power generation (assuming that's what your document is talking about!) and that the way this tax is calculated is based on the revenue obtained from selling the power — seems entirely logical to me, since the revenue is the easiest thing to actually measure and account for, and the taxt could be calculated as (say) a simple % of it.

Tony, I need also to clarify a GN-related issue, please: plant operation cost and generation taxes on revenues and on production will be recorded in account X. Generation tax means something like 'production tax'? Why 'on revenues' then? Thanks!!!

That is in fact what I already said several hours ago, if you'd care to read my answer below.

To be honest, I personally don't find the EN "very poor" at all — at first reading, there seems to be something slightly awry with the introductory sentence, but even that might be explained by surrounding context.

... shorthand for "Generation" (as all the "sub tasks" are "generation sub-tasks"). The English is very poor.
