Some people even played with the idea of re-opening the albergue which was closed many years earlier precisely because there was no electricity. It should be possible to lure at least some tourists this way now.
Up until 2006 electricity came from this humble building (1) with Central painted on its door. Two lines, just above head-height, run to the nearest house and provided barely enough energy to make it possible to leave the home during dark winter nights, states a newspaper article relating the inauguration.
The first edition (1933) of map 211 of the Spanish Instituto Geográfico y Catastral
shows a construction at the same spot as the current mill, but there are no powerlines nor any other indication suggesting
energy production. Other mills on the same sheet (e.g. Jánovas, Guaso)
have lines drawn.
The second edition (1952) has the caption Fábrica de Electricidad at the right spot. I therefore assume that production started at the earliest somewhere in the 1930s.
