Programmes are underway to rehabilitate the networks and bring them back to their original conveyance capacity within a few years. Taking this into account, the total future capacity of hydropower will increase to 2,627 MW. However, most hydropower plants are in a rather poor state due to lack of maintenance and therefore they do not operate efficiently. Furthermore, the existing power plants do not take into consideration the ecological aspects required in the EU Water Framework Directive (2000/60/EC) and until now no revitalization activities have been implemented.
