The project, located approximately 350 km south-east of Johannesburg, at the border between Kwa Zulu Natal and Free State, involved the construction of a generation and pumping plant with a total installed capacity of 1,332 MW, which allows the production of electricity at peak times and the re-utilisation of the water pumping it into the upstream reservoir in times of lower demand.

The works specifically involved underground civil works, including the installation of 4 pumps/turbines, pumping and return tunnels, balancing shafts, forced pipes, the underground excavations for the plant and transformers, the access tunnels to the various structures and the upstream and downstream intake works.
