A graphic testimony to the construction of the first hydroelectric plants in the valley of the River Esera.

The photographic collection
From 1913 to 1929 the Catalana de Gas y Electricidad company brought to completion in the Pyrenees of Aragon Ribagorza one pharaonic project for the construction of several hydroelectric plants and 225km transmission line in order to meet growing electricity demand of the city of Barcelona. The line was one of the longer in Europe at the time, and working conditions tested buildings and especially the people who made them possible. All this represented a considerable technological and human challenge which has immortalized through the photographic collection of over 2,000 photos that Catalana de Gas y Electricidad did and now are preserved in the photographic archive of the Museu de la Ciència i de la Tècnica de Catalunya.
