The power station has been operational as early as 2005 with a 6 MW generator.
In 2006 a new additional 16 MW generator was installed and went online in 2007.
Construction began in 2003 and in 2008 the three 55 MW generators were commissioned.
The power station contains 4 x 315 MW generators.
In 1941, the dam was complete and two of the 100 MW generators were operational.
The dam's power station sits at its middle base and contains the original 3 x 210 MW generators.
The two additional 250 MW generators were installed in another power plant.
The expansion of the power plant will include a new 40 MW generator.
Construction on the first stage of the project began in 1975 and the single 150 MW generator was operational in 1981.
The powerhouse is 690 ft. long and contains eight 75 MW generators.
