Looking at an ENTSOE paper, I have seen this table in which the typical ''loading factors'' of different generation types are listed (see figure below). But, what is this????
I was supposing that it is the ratio between the power that the generator usually produces in normal conditions over the nominal power of the generator. But, it looks strange to me, because if you look at the loading factors of Fossil base generators or hydro ones, it is between 0,5-0,7, but I know that these generators usually run at a value near to 100% of power because efficiency is much higher. I don't know if my sentence is correct.
This is the link of the document if you want to give a look to it
