The Pumped Storage Scheme consists of an upper and a lower dam; both of approximately 22 million cubic meters water capacity. The dams, 4.6 km apart, are connected by underground waterways, through an underground powerhouse which houses 4 x 333MW pump turbines. During times of peak energy consumption, water will be released from the upper dam through the pump turbines to the lower dam to generate electricity. During times of low energy demand the pump turbines are used to pump the water from the lower dam back up to the upper dam.

The project is scheduled to come on line during 2015/16.
