As part of the drive for greater energy efficiency, state-oil giant Saudi Arabian Oil Co., known as Saudi Aramco, has signed three new energy conversion agreements with a Japanese-Saudi consortium to build and operate cogeneration power plants in the kingdom.

The agreements for the cogeneration plants were signed with Marubeni Corp. and JGC Corp. of Japan and Saudi Aljomaih Energy & Water Co., Aramco said in an emailed statement on Thursday.

The plants will generate a total of 900 MW of power and 1500 tons of steam per hour when they commence operation in 2016 at the company’s Abqaiq, Hawiya and Ras Tanura facilities.

Aramco did not disclose the value of the deals but said it would hold a 50 per cent stake in the plants, which will have a thermal efficiency of more than 80 per cent, compared with conventional generation thermal efficiency of 40-50 per cent.
