DEWA's M-Station expansion at Jebel Ali 98% complete

By Wam

Dubai Electricity and Water Authority,DEWA, has completed 98 percent of the M-Station expansion project, the largest power generation and water desalination plant in the UAE.

Saeed Mohammed Al Tayer, Managing Director & CEO of DEWA, made the announcement during his visit to review the progress of the M-Station expansion project.

Nasser Lootah, Executive Vice President of Generation at DEWA, Mansoor Al Suwaidi, Vice President for Projects, Dr Maan Alafeefi, VP of Commissioning, and Masoud Kamali, Project Manager, also took part.

During the tour, Al Tayer was briefed by representatives from Siemens about the construction, engineering, and operational processes of the expansion project, with over 19.5 million safe man-hours.

M-Station’s current total capacity is 2,185 megawatts (MW) of electricity and 140 million imperial gallons of water per day (MIGD).

The station also operates at the highest levels of availability, reliability, and efficiency, and uses the most advanced technologies in the world.

The expansion project includes new power generation units, with an added 700MW capacity, to the station’s current total.

The expansion project has added two dual-fuel gas turbine generators, two heat-recovery steam boilers, and a steam turbine that is 90 percent fuel efficient.

This will increase the plant’s thermal efficiency from 82.4 percent to 85.8 percent, which is one of the highest thermal-efficiency rates in the world.

When completed, the project will increase the station’s total capacity to 2,885MW.

Since 2015, DEWA has been working with Siemens on the Jebel Ali M-Station expansion, and appointed Mott MacDonald as project consultant.

The combined total cost of the construction and expansion of M-Station, equipped with the latest smart devices and sophisticated heavy-duty technological systems, is AED 11.5 billion.

M-Station was built at a cost of AED 10.15 billion, and AED 6.2 billion were invested to generate 2,185MW of electricity from 6 Siemens F-model gas turbines, each with a capacity of 255MW; 6 boilers for waste-heat recovery; and 3 steam turbines, each with a capacity of 218MW.

The project has been implemented in phases since mid-2010. Water desalination systems, costing AED3.95 billion, use 8 desalination units, deploying Multi-Stage Flash (MSF) distillation technology, each with a capacity of 17.5 MIGD and totalling 140 MIGD, two dual-fuel-fired auxiliary boilers of 390 tonnes per hour, and 16 fuel-oil storage tanks, each with a capacity of 20,000 cubic metres, with total fuel-oil storage of 320,000 cubic metres.

DEWA is continuously working to build a robust infrastructure to enhance its total production capacity, which is currently 10,927MW of electricity and 470 MIGD.
