Villelongue

History of Villelongue

The Villelongue power plant was built in 1895. FerroPEM Pierrefitte plant has been running it ever since and has held the last concession to the hydroelectric operation since 2000, for the next 40 years. The current rights will then expire in 2040. The maximum flow is approximately 1.5m3/s during spring months. The power plant yearly production is around 30 GWh, which is almost entirely consumed in Pierrefitte plant itself.
