Dropping a rock down a 1500 foot deep hole

I'm throwing a rock down a 450 meter deep hole (1500 ft).

Animated description of how and why this hole was made:

This is a video of the drill (sorry for the bad quality):

The hole is in Austria at the bottom of lake Feldsee, and it is a part of a hydroelectric power plant.
During the day, when the price of electricity is higher, a lake will be emptied, producing 70 MW of electricity.
During the nighttime when the electricity is cheaper, the generator will be used as a pump, refilling the lake. The pump will have a capacity of 11,3 cubic meters per second.

The total drop height will be 524 meters, where this hole is 450 meters deep.

Alpine Meyreder was the main contractor for the hole project, and Bergteamet was the sub contractor drilling this hole.
