Dewa says the $3.2bn plant will produce 140 million gallons of desalinated water per day
Construction of Dubai Electricity and Water Authority’s (Dewa) $415.7m (AED1.5bn) M-Station expansion has been completed.
The project has been inaugurated by HH Sheikh Hamdan bin Rashid Al Maktoum, Deputy Ruler of Dubai, Minister of Finance, and President of Dewa.
M-Station is the largest water and desalination plant in the UAE, according to state news agency WAM. The total construction and expansion cost of the plant, which recorded 20 million safe man-hours, has been recorded at $3.2bn (AED11.5bn).
UK-headquartered Mott MacDonald was appointed as the project consultant for M-Station, which generated 2,185MW of electricity from six Siemens F-model gas turbines, six Doosan waste-heat recovery boilers for steam generation, and three Alstom steam turbines — each with a capacity of 218MW — before the Jebel Ali plant underwent its expansion.
As part of the project, 16 fuel-oil storage tanks — each with a capacity of 20,000m³ — totalling 320,000m³ capacity have been built.
Following expansion, the overall capacity of M-Station has reached 2,885MW and 140 million gallons of desalinated water per day. And with the multimillion-dollar expansion, the plant has added new generating units with a capacity of 700MW.
M-Station’s extension also includes two dual-fuel gas turbine generators, with a capacity of 263.5MW, two waste heat-recovery boilers for steam generation, and a Siemens back-pressure steam turbine with capacity of 173MW.
According to Dewa, the extension has a 90% fuel efficiency, which has hiked the M-Station’s overall fuel efficiency from 82.4% to 85.8% — making the plants’s fuel efficiency rate one of the highest in the world.
