Dubai’s 250MW hydroelect­ric power plant in Hatta is 29% complete


Constructi­on of the UAE’s first

hydropower is progressin­g with 29% of the work already


It will have a production capacity of 250 megawatts (MW), a storage capacity of 1,500 megawatt-hours, and a life span of up to 80 years. This is the first station of its kind in the GCC with investment­s up to


The first 37-metre-high Roller Compacted Concrete (RCC) wall is now complete at the project’s upper dam. The station will use water in the Hatta Dam and an upper dam. The Hydroelect­ric power plant

is an energy storage with turnaround efficiency of 78.9% that utilises potential energy

of the water stored in the upper dam which is converted to kinetic energy during the

flow of water through the 1.2km subterrane­an tunnel, and this kinetic energy rotates

the turbines and converts mechanical energy to electrical energy which is sent to the grid. Then to store energy again, clean energy generated at the MBR Solar Park is used to pump the water through this tunnel back to the upper dam by converting the electrical energy to kinetic energy and

then finally storing it as a potential energy in the upper

dam that is being built.
