PROJECT DETAILS

The arrangement of the entire Taweelah B Plant, previously managed by Al Taweelah Power Company (ATPC), as well as the new capacity added as part of the EPC contract, all of which is now under the management of Taweelah Asia Power Company (TAPCO), can be divided in three (3) different phases as detailed below:

Commissioned between 1995 and 1997, comprises six identical units; a unit being made up of a steam raising boiler, a condensing steam turbine generator, with steam extraction to a multi-stage-flash seawater desalination distiller.

The complete Taweelah New B Extension was brought into commercial operation on October 30th 2008.

The Plant comprises of 3 Gas Turbines, which operate in combined cycle mode (two of which can operate in open cycle), each Gas Turbine of which exhausts into a heat recovery steam generator raising steam to drive a back pressure steam turbine generator under normal operation. The steam is then fed to four multi stage flash seawater desalination distillers.
