DAMMAM: Saudi Arabia has revised up its estimates for the amount it will invest in power projects over the next decade to more than 400 billion riyals ($106.6bn) from 300bn, its deputy electricity minister said.

"Some time (ago) we announced 300bn (riyals) and we increased it due to the latest developments especially in the housing sector and also the new infrastructure funded by the government," Saleh Al Awaji said at a water and power conference in Dammam yesterday.
