The Project

the project

The Taweelah B Power and Desalination Complex are comprised of three different power generation and desalination facilities of various technologies: Initial B Plant (IB), Initial B Extension (IBE), and the New B Extension (NBE).
The net water desalination capacity allows the Taweelah B plant to produce a net contracted water capacity of 160 MIGD and 2000 MW.

Initial B Plant

The Initial B Plant is a thermal plant with conventional boilers and turbines commissioned between 1995 and 1997. It has six steam generators and steam turbines that provide an installed net power capacity of 750 MW and a six multi-stage flash (MSF) desalination unit that provides a net water production capacity of 69.1 MIGD. The distillers are supplied with steam from the extraction and, in case of unavailability or dispatch shut down of the turbines, can be supplied steam from the bypass stations.

Initial B Extension Plant

The Initial B Extension, completed in 2001, has GE Frame 9E gas turbines as its prime movers. It has an installed net power generation capacity of 330 MW and a net desalinated water production capacity of 22.5 MIGD provided by two gas turbines, two heat recovery steam generators (HRSGs), a single backpressure steam turbine, and three MSF desalination units.

New B Extension Plant

The New B Extension is one of the more recent generations of a combined cycle cogeneration plant, commissioned in 2008. The frame F technology gas turbines are Siemens machines. It has a net power capacity of 970 MW and net water production capacity of 69.2 MIGD.
