The turbines at coal fired power stations are steam driven. The steam is produced using highly purified water demineralised water. This water needs to be recovered due to the high costs involved in its production and also to save water. When the spent steam leaves the turbine it is at a very low pressure and high volume.
The power plant will have six units that will together generate 4,800MW. The first unit is scheduled to be commissioned in early 2012. The remaining units will be commissioned at regular intervals of nine months, with the last due for completion in 2015. The plant will be the largest drycooled coalfired power station in the world.

Dry cooling systems tend to be more economical for natural gas combinedcycle plants because the amount of cooling needed is much less per megawatthour than for coal or nuclear plants. More than 15% of operating generating capacity from natural gas combinedcycle plants in the United States use dry cooling technology.
