Description:	Potential energy of end volume

Storage End Potential Energy is the potential energy of the End Volume and is calculated as:

End Potential Energy = End Volume × Downstream Efficiency × time

For example, using the metric volume Model:

Hydro generator efficiency is in MW/m³/s
End Volume is in CMD (cubic metre days) which is equal to 86400m³

Therefore the time conversion is GWh =Downstream Efficiency × 86400 / (3600 × 1000) = Downstream Efficiency × 0.024 i.e.

End Potential Energy = End Volume × Downstream Efficiency × 0.024

In a cascading hydro river model the potential energy is summed downstream so the total potential energy declines as you traverse down the river chain.
