Στην Αφρική το μεγαλύτερο υδροηλεκτρικό φράγμα του κόσμου;

Ένα υδροηλεκτρικό φράγμα διπλάσιας ισχύος από το μεγαλύτερο στον κόσμο – το Φράγμα των Τριών Φαραγγιών, στην Κίνα – ενδέχεται να ανεγερθεί μέσα στα επόμενα χρόνια στην Αφρική. Εταιρείες από την Ισπανία, την Κίνα και τη Νότια Κορέα «ερίζουν» για την υλοποίηση του φιλόδοξου έργου που, όπως όλα δείχνουν, θα αρχίσει προς το τέλος του 2015, ωστόσο δεν λείπουν και οι ενστάσεις.

Το φράγμα Inga 3, που στην πρώτη του φάση θα έχει ισχύ 4,800MW με προοπτική δεκαπλασιασμού, πρόκειται να κατασκευαστεί στον ποταμό Κονγκό, το βαθύτερο στον κόσμο, 230 χλμ. νοτιοδυτικά της Κινσάσα, ενώ εκτιμάται ότι θα στοιχίσει μεταξύ 9 δισ. και 14 δισ. δολαρίων. Σύμφωνα με αξιωματούχους, η ανέγερσή του θα έχει ολοκληρωθεί έως το 2021.
