PROJECT DETAILS

The Taweelah B Power and Desalination Complex is comprised of three distinct power generation and desalination facilities of different technologies, known as ‘Initial B Plant’ (IB), ‘Initial B Extension’ (IBE), and the ‘New B Extension’ (NBE).

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.

Commissioned between 1999 and 2001, comprises two gas turbines (operating in either simple or combined cycle) each exhausting into a heat recovery steam generator raising steam to drive a back pressure steam turbine generator which, in turn, supplies steam to three multi-stage-flash seawater desalination distillers.

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.
