Work on Track on Hatta Pumped Hydro Storage Project

Construction work is progressing to schedule on the Hatta pumped hydro storage project in Dubai, the first hydropower project in the GCC.


The client for the project, Dubai Electricity & Water Authority (Dewa), reported that the service tunnelling operations have been completed and that construction works are progressing on the upper dam of the scheme.


The progress was revealed following a visit to the site from HE Saeed Mohammed al-Tayer, MD and CEO of Dewa.


Dewa awarded the $391m engineering, procurement and construction (EPC) contract for the project to a consortium of Austria’s Strabag, Andritz Hydro and Oskar in August 2019. France’s EDF is the engineering consultant for the project, which is on schedule to be commissioned by February 2024.


The hydro project will use water stored in the Hatta Dam, near the Oman border. 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 300m above the dam level.
