A run-of-the-river plant, it can supply clean energy to approximately 23,000 homes. Its most interesting feature lies in its historical significance. It was built between 1912 and 1918, as part of an extraordinarily important engineering project at the time, to feed a power line with the highest voltage in Europe at the time, which ran to Barcelona. Restored according to its original architecture, it is a magnificent example of an early 20th-century industrial facility.
