Dubai Electricity and Water Authority (DEWA) has announced that CEO Saeed Mohammed Al Tayer recently reviewed the progress of the M-Station expansion project, the newest and largest electricity generation and water desalination plant in the UAE, and that 70 per cent of the project has been completed

Al Tayer was accompanied by Nasser Lootah, executive V-P of generation, Mansoor Al Suwaidi, V-P 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 and 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 per cent of the project has been completed. This includes pouring 45,000 cu/m of concrete (96 per cent complete), erecting 4,900 tonnes of structural steel and heavy metal work (75 per cent complete), and 8.3mn 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 US$3.13bn. 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 per cent fuel efficient. This will increase the plant?s thermal efficiency from 82.4 per cent to 85.8 per cent, 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 470mn imperial gallons of desalinated water per day (MIGD). M-Station?s current total capacity is 2,185MW of electricity and 140 MIGD. According to DEWA, 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 US$2.76bn and US$1.69bn were invested to generate 2,185MW of electricity from six gas turbines (F-model) from Siemens, with a capacity of 255MW for each unit, six boilers for waste-heat recovery and three steam turbines, with a capacity of 218MW each. The project has been implemented in phases since mid-2010. Water desalination systems costing US$1.08bn use eight 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 cu/m, with total fuel-oil storage of 320,000 cu/m.
