The plant, close to the Abu Dhabi border, will have a capacity of 1,500MW and 100-120 million gallons a day (g/d) of water.

The project has been divided into two packages. The first covers the power plant and includes the gas turbines, auxiliary boilers, steam turbines and all associated works.

The second package, covering the desalination element of the scheme, includes multi-stage flash desalination units, sea water pumps, potable water pipes and associated works.

Bidders can submit a bid for one or both packages. If different companies are selected for the two packages, Dewa says it could invite the them to form a consortium, led by the power plant bidder. This would be awarded on a turnkey basis.

The plant will be commissioned in stages in 2011 and 2012. The closing date for completed tenders is 15 April.
