No, I claim that you don't know what you're talking about because you think the units were wrong in the given context and that the arithmetic values were wrong, which they weren't.
You keep repeating that as if you think it's going to convince somebody, but, in fact, when you divide an amount of energy produced, such as 4 terawatt hours, by a length of time such as a year, you get a power, such as 500 megawatts, which does indeed tell you how much energy was produced over that length of time.
