Dubai Electricity & Water Authority (Dewa) has awarded a AED58m ($15.8m) contract to France’s EDF for the engineering consultancy contract on the planned AED1.92bn Hatta dam hydroelectric power station, the first hydro project in the GCC.

The proposed hydropower scheme will have a capacity of 250MW.

The consultancy contract will cover design, hydro-geological, geological, environmental, geotechnical and deep excavation studies. The work will also involve providing consultancy services for deep-water tunnel designs, dam and hydroelectric power station, tender for material supply, supervision of construction work, site installation and commissioning.

MEED reported in February that eight firms had submitted proposals for the engineering consultancy role.

The project will use water stored in the Hatta Dam, near the Oman border, and will be the first hydroelectric facility in the GCC.

The existing Hatta Dam can store up to 1,716 million gallons of water. The project will involve the construction of an upper reservoir, which will be able to hold up to 880 million gallons. The upper reservoir will be located 300 metres above the dam level.

During off-peak hours, turbines will use solar energy to pump water from the dam to the upper reservoir.

The project will support the AED1.3bn ($354m) Hatta development plan, which was announced earlier in November. Under the plan, three main areas, including an economic and service zone, tourism and sports zone and a culture and education area, will be built in the Hatta area.

The Hatta development plan is part of the UAE’s 2021 Vision, launched in 2014.
