UAE's largest desalination plant is 53% completeby Jochebed Menon on Dec 28, 2016
Dubai Electricity and Water Authority’s (DEWA) M-Station, the largest power production and water desalination plant in the UAE, is 53% complete.
The total cost of M-Station will be $3.16bn (AED11.62bn), while the estimated cost of the expansion project is $400m (AED1.47bn).
The project will be completed and delivered by end of April 2018, DEWA said in a press release.
Two gas turbine generators will be inaugurated on 31 May, 2017, which will be followed by the addition of two heat recovery steam turbine generators and one back-pressure steam turbine on 30 April, 2018.
This will increase the plant’s thermal efficiency from 82.4% to 85.8%, which is considered one of the highest thermal-efficiency rates in the world.
The expansion project includes new power generation units with a capacity of 700MW to be added to the current capacity of the station to eventually produce 2,760MW by 2018.
Its current total capacity is 2,060MW of electricity and 140 million imperial gallons of water per day (MIGD).
The M-Station was launched in 2013 at a cost of $2.76bn (AED10.15bn).
This includes $1.7bn (AED6.2bn) for electricity to provide 2060MW through 6 Siemens (F) model gas turbines with a capacity of 234MW each, six heat recovery steam turbine generators, and three back-pressure steam turbines with a capacity of 218MW each.
The project has been completed in phases since mid-2010.
The desalination cost is $1.08bn (AED3.95bn) using eight desalination units with multi-stage flash distillation (MSF) technology, with a capacity of 17.5 million MIGD for each unit, with a total of 140 million gallons per day.
DEWA, which currently operates 21 (400kV) substations and 222 (132kV) substations, continues to build a strong infrastructure to enhance its installed capacity, which is currently 9,900MW of electricity and 470 million MIGD.
DEWA has appointed Mott MacDonald as the consultancy company for the project.
