Hatta Hydro Electric Power Plant
Construction of a Pumped Storage Hydro Power Plant located near the city of Hatta in the Hajar Mountains, 140 km southeast of the city of Dubai.
The Hydro Power Plant is a major component to achieve the targets of Dubai’s Clean Energy Strategy 2050.
The existing Saad Hatta Al Awwal Dam will be used as the lower reservoir, the upper reservoir will be approx. 150m higher.
Both reservoirs will be connected by a 1.2 km long pressure tunnel.
The upper reservoir will be constructed with two roller-compacted concrete dams with a height of approximately 35 m and 70 m.
Additionally a powerhouse with 2 units capable of generating a total net power of 250MW over the 6 hours generation cycle.
Waterways will consist of one tunnel of approx. 1300m length and 7m diameter to feed the powerhouse with approx. 200m³/s.
Also part of the works is the construction of two road tunnels with a length of approximately 470 m and 440 m using blast excavation as well as the construction of the reinforced outflow and intake structures, several ancillary buildings and mechanical and electrical systems.
