Ideological elements
Sun Yat-sen, founding father of the Republic of China originally envisioned the idea of TGD
John L. Savage, the USBR chief design engineer, John L. Savage, surveyed the area and drew up a dam proposal.
Mao Zedong supported the project but the Great Leap Forward and the Cultural Revolution slowed progress.
The NPC approved the dam in 1992 with a 67% approval rate which is by far the lowest motion adopted by NPC.

The Scale Effect
By November 2013, the profit of TGD has reached 0.1831 Trillion RMB(approx. US$ 29.2billion) enough to recover investment cost.
All kinds of organizations were involved in this project, but only few relevant ones were giving advices.
The construction of this project considered the users' demands, but it was fundamentally nationalize.
