A multi-million-euro Endesa investment to modernise the power plant

The type of machinery turns in one direction to pump the water up and the other to bring it down again. The machines are big and heavy. Every time they start up, the alternator's polar masses turn. It's as if a wire were being continually bent, explain the engineers Andrés Muñoz and Antonio Velasco, who are responsible for the Endesa power plant. Every so often the material has to be checked for signs of fracture. The last check was made three years ago, and with the help of the University of Stuttgart (Germany), the remaining useful life of the power station was predicted, with a fixed number of uses that could not be exceeded for safety reasons.
