Thanks Jay; Some study on my own.

What I found was that the equivalent power generated would displace 40M Tons of coal generation, or 60M tons of Oil. That would displace China's net imports of oil; however very little oil fired generation. Much more coal. I expect that little displacement of alternate electric generation will occur, as demand grows to absorb supply.

The HV DC transmission aspect surprises me a bit. Only because my limited understanding of US power transmission suggests it uses very little DC tx. I'd guess it probably makes more sense to import LNG from the ME or Australia/SE Asia than Trinidad. <g> Trinidad would be a short hop to US markets, though. I'm still fond of converting the gas locally, to say ammonia, and shipping the value add product overseas. Displacing local production in gas tight markets. BWDIK?

My guess is the power from Three Gorges will help competitive position of China's industry long term, even with cost overruns. Though this huge number is actually a pretty small slice in respect to overall energy needs. Still need to do some work on basic metals production. Though after a nap, I suspect. <g>

In 1997, the electric power sector consumed over one-third of the country’s nearly 1.4 billion tons of coal. Seventy-five percent of all electricity produced in China was generated using coal. In contrast, hydroelectricity produced 23% and nuclear 1%.

THE ELECTRICITY:

Machinery: The two power stations flanking the dam's central spillway will operate 26 of the world's largest turbine generators, 700 megawatts each.

Capacity: Total generating capacity will be 18,200 megawatts, or as much as big 18 nuclear power stations.

Transmission: Fifteen 500,000-volt transmission lines will send electricity to Shanghai and elsewhere throughout East China, Central China and eastern Sichuan Province.

Output: 84.7 billion kilowatt hours of electricity annually, equivalent to burning 40 million tons of coal.

China's Crude Oil Imports Exceed 60 Million Tons
China's imports of crude oil exceeded 60 million tons from January to November this year, representing a 97 percent increase over the same period of last year.

One tonne of oil equivalent equals approximately:

Heat units 10 million kilocalories
42 gigajoules
40 million Btu
Solid fuels 1.5 tonnes of hard coal
3 tonnes of lignite
Gaseous fuels See natural gas and LNG table
Electricity 12 megawatt-hours
