Hatta Pumped Storage Hydroelectric Project
Hatta in the Hajar Mountains, 140 km southeast of the city of Dubai, United Arab Emirates (UAE). 2019-2024Products supplied: NC-bolts. All in Pc-coating.
The Hatta pumped storage hydroelectric project will be the first hydroelectric power station in the Arabian Gulf region (GCC). It is part of the Dubai Clean Energy Strategy 2050 program, which has a goal of providing 75% of Dubai’s total power generation from clean energy sources by 2050. Designed to run for 80 years, our Pc-Coated NC-bolts was a natural choice to ensure the specified service life in the most challenging environments.
The Hatta hydroelectric facility will consist of a lower and an upper reservoir to store and use the surplus water from the Hatta Dam. Both reservoirs will be connected by a 1.2 km long pressure tunnel. Additionally 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.
