Talk:Hydroelectric dam

The article states that: (for example, at about the time of the First Tiberium War, hydroelectric stations at Niagara Falls produced roughly 4,400 megawatts of electricity). First off, I don't know how someone could get that information. Secondly, if it did produce 4,400 megawatts of electricity, during what sort of time span is it? 1 year? 2? 3? Less than one year?
