Russian tycoon plans to supply power to China

One of Russia's richest men is planning to invest billions of dollars in a scheme to sell electricity to China.

Oleg Deripaska wants to build a series of hydro-electric dams in remote eastern Siberia and export the power southwards to cash in on Asia's booming economies.

He says he could be shipping 15 billion kilowatt hours a year to China within the next five years.

He told the BBC's Daniel Sandford the potential market is 60 billion kilowatt hours a year - enough electricity to power Greece.
