In 1980, the electric utility company �lectricit?de France ( EDF, Electricity of France ) built a second dam, the Pont des Ch�vres, on the Francis pump-turbines and a 150 MW Pelton turbine.

The dam's power station, Kurobe No . 4, is located underground and contains four generators which are powered by Pelton turbines for a total installed capacity of 335 MW and average annual generation of 1 billion kWh.
33.
The plant has Pelton turbines, with a total installed capacity of 90 MW . The plant has a net level declination of 490.6 m, and a designed flow of 7.33 m 3 / s per unit.

The formula implies that the Pelton turbine is " geared " most suitably for applications with relatively high hydraulic head " H ", due to the 5 / 4 exponent being greater than unity, and given the characteristically low specific speed of the Pelton.

By January 1961, two of Kurobe No . 4's Pelton turbines had begun operation at an initial capacity of 154 MW . In August 1962, the third turbine was in operation and by June 1963, the dam was complete at a final cost of ?51.3 billion ( $ 142.5 million ( 1963 ) ).
