The national grid calls for the five power networks – operated by Abu Dhabi Water & Electricity Authority (ADWEA), Dubai Electricity & Water Authority (DEWA), Sharjah Electricity & Water Authority (SEWA), the Federal Electricity & Water Authority (FEWA) and Union Water & Electricity Company (UWEC)– to be interconnected by a 400-MW transmission backbone.
Under the project, a 400-kV link will connect the Taweelah complex in Abu Dhabi, the H station at Al-Aweer in Dubai, the FEWA-operated Dhaid station in Sharjah emirate and the UWEC power and desalination plant at Qidfa in Fujairah. The Sharjah network will be linked to the grid via a 220-kV link between Dhaid and the Sajaa station, operated by SEWA.
The project is expected to be tendered in three packages. Package 1 will be the largest and involve the construction of a 400/220-kV substation with at least two 500-MVA transformers at Dhaid. Package 2 will be the transmission line works and cover the supply and installation of about 200 kilometres of 400-kV and 40 kilometres of 220-kV transmission line. The final package will be for the telecommunications and the control and settlement centre. All three packages are expected to be issued for bid by the third quarter of 2003.
