Umm Al Houl combined-cycle power plant make-up
The project encompasses the construction of a natural gas-fired combined cycle power plant along with a desalination plant. The electricity and water produced from the project will be purchased by Qatar General Electricity and Water Corporation for a period of 25 years.
The plant will be equipped with six gas turbines, four steam turbines and 10 generators. It will be divided into two power blocks with each block consisting of three gas turbines that will operate two downstream steam turbines.
Power from the plant will be transmitted to the country's power grid via a newly built substation.
The plant will also include process and plant drainage systems, system control and data acquisition connection between facility, substations, control centres and fuel supply systems.
Details of the desalination plant
The desalination plant will have a capacity of 136.5 million imperial gallons a day (MIGD) of net water capacity, of which 60MIGD will be produced through reverse osmosis technology, while 76.5MIGD will be produced using multiple-stage flash technology.
The plant will require large volumes of water for cooling requirements including cooling the steam produced and used within the steam turbines. Significant volumes of water will also be required for the desalination process.
The plant will also include seawater intake and discharge facilities along with portable water facilities including pumping stations, reservoirs and connection pipelines as well as disinfection and wastewater treatment facilities.
