DEWA launches RFEOI for 250 MW Hatta hydroelectric project
Dubai Electricity and Water Authority (DEWA) has launched a request for expression of interest (RFEOI) to develop the Hatta hydroelectric project in Dubai.
The project is the first of its kind in the Arabian Gulf, with a total capacity of 250 MW, and is expected to last between 60 to 80 years.
The hydroelectric power station is expected to generate electricity by making use of the existing water stored in the Hatta Dam, which can store up to 1,716 million gallons, and an upper reservoir that will be built in the mountain that can store up to 880 million gallons. The upper reservoir will be 300 meters above the dam level.
During off-peak hours, turbines that use clean and cheap solar energy will pump water from the lower dam to the upper reservoir. During peak-load hours, when production costs are high, turbines operated by the speed of waterfall from the upper reservoir will be used to generate electricity and connect it to DEWA’s grid.
The efficiency of power production aims to reach 90% with a 90-second response to demand for electricity.
On June 12, 2017, we reported that DEWA awarded a AED58 million consultancy contract for the pumped-storage hydroelectric power station at Hatta Dam to France’s EDF. The consultancy contract covers design, hydro-geological, geological, environmental, geotechnical, and deep excavation studies. It also includes consultancy on deep-water tunnel designs, the dam and hydroelectric power station, the tender for material supply, supervision of construction work, site installation, on-site testing and commissioning.
We have recently reported about several projects in Saudi Arabia:
