Green Energy

China Three Gorges says that the enormous integrated energy site’s power will be dispatched to the Beijing-Tianjin-Hebei cluster in northern China via an ultra-high voltage power transmission line.

These are build in the desert and power is transmitted via a single large transmission line.

It's probably easier to do so from a planning and regulatory standpoint, but I agree that otherwise it would be wiser to have them closer to the end users.
