The Bieudron power station forms part of the Cleuson-Dixence complex. It was built jointly by Grande Dixence SA and EOS between 1993 and 1998, at a cost of CHF 1.3 billion, to increase the generating capacity of the Grande Dixence complex.

The Bieudron power station alone holds three world records, for the height of its head (1883 m), the output of each Pelton turbine (3 x 423 MW) and the output per pole of the generators (35.7 MVA).

It was out of service for 9 years following the rupture of the Cleuson-Dixence penstock in December 2000. The rehabilitation of the penstock, which conveys water to the power station from the Grande Dixence dam, began in 2005 and took 4½ years, involving 600 people working around the clock 7 days a week . The commissioning tests for the Cleuson-Dixence complex started in the middle of 2009 and the Bieudron power plant produced its first kilowatt-hours in January 2010.
