UPDATE 2-No need for further Saudi capacity boost yet-Naimi

ROME, April 19 (Reuters) - Top oil exporter Saudi Arabia has no plans to embark on further capacity expansion as long-term oil demand forecasts fall and alternative fuel supplies rise, the Saudi oil minister told industry newsletter Petroleum Argus.

The holder of the world's largest oil reserves sees no need to go beyond its 2009 capacity target of 12.5 million barrels per day "at least up to 2020," Oil Minister Ali al-Naimi said.

Long-term future energy demand forecasts have fallen sharply, he said in the interview given to the weekly on April 11, casting doubt on the need for more Saudi oil.

Demand forecasts have fallen as low as 106 million bpd in 2030, down from previous estimates as high as 130 million bpd. The world currently consumes around 86 million bpd.

"The projection of demand is on the decrease," Naimi said. "The projection of alternative fuels is on the rise. Therefore, it behoves us to pause, instead of expending unnecessary funds on expanding capacity that will probably not be needed," he said. "We will watch what happens in the coming years. It is a pragmatic position."

Saudi Arabia has spent tens of billions of dollars on projects to meet growing world demand and maintain spare production capacity of 1.5-2.0 million bpd to deal with any unexpected outages in global supply. The kingdom has previously said it could take output capacity of 15 million bpd.

The kingdom is the only oil producer with substantial spare capacity that can be brought online quickly.

"We are idling at around 9 million bpd and we will reach capacity of 12.5 million bpd by 2009," Naimi said. "That is substantial spare capacity. As far as I know, all the latest projections, at least up to 2020, do not require anything higher than that."

A Saudi oil official said earlier this month that output stood at around 9 million bpd. Current capacity is around 11.3 million bpd.
