Dewa completes 82pc of M-Station expansion

Dubai Electricity and Water Authority (Dewa) has completed 82 per cent of the M-Station expansion project, the newest and largest electricity generation and water desalination plant in the UAE.

Saeed Mohammed Al Tayer, MD & CEO of Dewa was briefed by Siemens’ representatives on the construction, engineering, and operational progress of the expansion project, which is going according to schedule. To date, most of the civil work has been done, and 10.9 million safe man-hours recorded without any injuries.

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 million imperial gallons of desalinated water per day (MIGD). The station adopts the highest levels of availability, reliability, and efficiency, using the most advanced technologies in the world. The station’s total capacity will reach 2,885MW when the expansion project is completed in Q3 of 2018.

The station 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.

Since 2015, Dewa has been working with Siemens on the Jebel Ali M-Station expansion, as the combined total cost of M-Station construction and expansion is Dh11.5 billion ($3.1 billion). M-Station is equipped with the latest smart devices and sophisticated heavy-duty technological systems. It was built at a cost of Dh10.15 billion. Dh6.2 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 Dh3.95 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 works tirelessly to build a robust infrastructure to enhance its total production capacity, which is currently 10,200MW of electricity and 470 MIGD. – TradeArabia News Service
