What is the average power output of a hydroelectric power plant?

Plant Load Factor varies widely with Hyrdo Plants because of Location and Control Method. Some large plants can produce up to 1000 Mega Watts (MW) while smaller Hyrdo Stations (About 60 - 80% or all active Hyrdo Generation is through Hydro Stations) can boost anywhere from 80 MW to 500 MW respectfully. I don't think there is a National Average but I think it's about 200 MW's. I personally factor in High Head/Low Power units because most of those locations historically do transconnect the National Grid and return, on average, about 50-100 KW's to the grid. That figure is loosely stated because we don't regulate their usage really and since we can't store power, we can only restrict it, that figure can be annually or daily. Depends on the location.
