Unique hydroelectricity far from water

A very unusual hydroelectric power plant is located near the town Lestervill, Missouri. The nearest water source - about 80 miles. How, then it works and whether you need it at all?

This power station consists of two remote at a distance from each part and only works at peak load points in the grid. Water tank is opened and the water flows down the turbines. As soon as the load on the network drops, water, using residual electricity back into the tank.

Thus, it appears that hydroelectricity can be considered a self-contained battery. The cost of the project at the time of launch in 2010 was about half a billion dollars. The tank holds about 5 billion cubic meters of water.
