Dewa's giant power plant on track for 2018 launch

DUBAI, December 27, 2016

Dubai Electricity and Water Authority (Dewa) said it has completed 53 per cent of the work at M-Station, the largest power production and water desalination plant being built in the emirate at a cost of Dh11.6 billion ($3.15 billion).

The M-Station project was launched in 2013 at a cost of Dh10.15 billion. This included an estimated Dh6.2 billion towards boosting electricity output to 2,060 MW through six Siemens (F) model gas turbines with a capacity of 234 MW each, six heat recovery steam turbine generators, and three back-pressure steam turbines with a capacity of 218 MW each.

Mott MacDonald is the consultancy company for the project, which is set to be completed and delivered by end of April 2018.

According to Dewa, the estimated cost of the expansion project has been put at Dh1.47 billion. It will include setting up of new power generation units with a capacity of 700 MW to be added to the current capacity of the station to eventually produce 2,760 MW by 2018.

Its current total capacity is 2,060 MW of electricity and 140 million gallons of water per day (mgpd).

Dewa pointed out that the station adopts the highest levels of availability, reliability, and efficiency, using the most advanced technologies in the world. It has successfully completed 3.9 million safe man-hours without any injuries.

Saeed Mohammed Al Tayer, the managing director and chief executive of Dewa, was briefed by representatives from Siemens on the project including its operational process and completion.

Nasser Lootah, the executive vice president of generation at Dewa, and Mansoor Al Suwaidi, the vice president for projects generation at Dewa, joined Al Tayer during the tour.

The Dubai utility firm is also set to inaugurate two gas turbine generators in May next year followed by the addition of two heat recovery steam turbine generators and one back-pressure steam turbine on April 30 in 2018.

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

Dewa said the project has been completed in phases since mid-2010. The desalination cost is put at Dh3.95 billion using 8 desalination units with multi-stage flash distillation (MSF) technology, with a capacity of 17.5 million MIGD for each unit, with a total of 140 million gallons per day.

There are 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. The total fuel storage tank’s capacity is 320,000 cu m, it stated.

The utility company continues to build a strong infrastructure to enhance its installed capacity, which is currently 9,900MW of electricity and 470 million MIGD.

It enhanced the efficiency rate between 84-90 per cent, while production capacity improved by 27 per cent in 2015 compared to 2006, with the use of efficient technologies in electricity production and desalination.

Dewa currently operates 21 (400kV) substations, and 222 (132kV) substations and has achieved promising success in energy transmission and distribution.-TradeArabia News Service
