Al Taweelah Power and Desalination Complex

The Al Taweelah Power and Desalination Complex is located approximately 50 kilometres to the Northeast of the Emirate of Abu Dhabi. It has two power and water plants, Taweelah A1 and Taweelah B, and Taweelah RO, which will be the world’s largest RO facility when fully commercially operational. 

Taweelah A1 is a combined-cycle power plant and thermal-based water desalination facility. It uses ten gas turbines, ten heat recovery steam generators and three steam turbines. Abu Dhabi National Energy Company (TAQA) owns 60 per cent of the plant with ENGIE and Total each holding 20 per cent.

The Taweelah B Power and Desalination Complex comprises three distinct power generation and desalination facilities that use different technologies, including simple, open and combined-cycle gas turbines and multi-stage flash distillation. TAQA own 60 per cent of the plant, Marubeni owns 14 per cent, BTU Power and Powertek each own 10 per cent and Kyuden owns 6 per cent.

The new Taweelah RO desalination plant is part of the Al Taweelah Power and Desalination Complex and will be the largest RO water desalination plant in the world when fully commercially operational. The plant will be 44 per cent bigger than the world’s current largest RO plant in terms of capacity, supplying 200 million imperial gallons per day (909,200 cubic metres per day). In June 2022, production of desalinated water using low carbon-intensive RO technology from Taweelah RO reached 50 per cent capacity, providing 100MIGD of desalinated water. A partnership between Abu Dhabi National Energy Company (TAQA) and Mubadala Investment Company holds a 60 per cent equity interest in the Taweelah Reverse Osmosis project with the remaining 40 per cent held by ACWA Power.
