The company

Mini hydro

The origin of Ennera dates back more than 100 years, to a hydroelectric plant built in Zaldibia to service a blossoming iron industry for railway components that would eventually become CAF.


This industry later became CAF, an international railway component manufacturer that employed more than 7000 people the world over and had an annual turnover of around 2000 million dollars.

Energy subsidiary

CAF set up Ennera in 2007 as a subsidiary for the purpose of entering the renewable energy business. To do this, it transferred ownership of the Zaldibia plant to Ennera.
