DEWA completes 70% of M-Station expansion

HE Saeed Mohammed Al Tayer, MD & CEO of Dubai Electricity and Water Authority (DEWA), has reviewed the progress of the M-Station expansion project. M-Station is the newest and largest electricity generation and water desalination plant in the UAE. Al Tayer was accompanied by Nasser Lootah, Executive Vice President of Generation, Mansoor Al Suwaidi, Vice President for Projects Generation, Masoud Kamali, manager for the project, Adel Shukralla, Senior Manager of Projects at M-Station, and Majed Abdullah, Senior Manager of Administration (Fire & Security).

Al Tayer was briefed by Siemens representatives on the construction, engineering, and operational progress of the expansion project, which is going according to schedule. Over 70% of the project has been completed. This includes pouring 45,000 cubic metres of concrete (96% complete), erecting 4,900 tonnes of structural steel and heavy metal work (75% complete), and 8.3 million safe man-hours without any injuries.

Since 2015, DEWA has been working with Siemens on the Jebel Ali M-Station expansion, as the total cost of M-Station construction and expansion is AED 11.5 billion. The station’s total capacity will reach 2,885MW when the expansion project is completed in 2018. This includes the provision of new power generating units, adding 700MW to the installed generation capacity of M-Station. The expansion project includes the addition of two dual-fuel gas turbine generators, two heat-recovery steam boilers, and a steam turbine that is 90% fuel efficient. This will increase the plant’s thermal efficiency from 82.4% to 85.8%, which is one of the highest thermal-efficiency rates in the world.

DEWA works tirelessly to build a robust infrastructure to enhance its total production capacity, which is currently 10,200MW of electricity and 470 million imperial gallons of desalinated water per day (MIGD). M-Station is the newest and largest electricity generation and water desalination plant in the UAE, with a current total capacity of 2,185MW of electricity and 140 MIGD. The station adopts the highest levels of availability, reliability, and efficiency, using the most advanced technologies in the world. It is equipped with the latest smart devices and sophisticated heavy-duty technological systems. M-Station was built at a cost of AED 10.15 billion. AED 6.2 billion were invested to generate 2,185MW of electricity from 6 gas turbines (F-model) from Siemens, with a capacity of 255MW for each unit, 6 boilers for waste-heat recovery and 3 steam turbines, with a capacity of 218MW each. 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.
