Siemens Power Transmission and Distribution is delivering a turnkey 400kV/132kV substation to Dubai Electricity and Water Authority (DEWA) as part of expansion plans for the UAE power supply system. The substation will link the H Station power plant at Al-Aweer to the country’s power supply network. It will also complete the Emirates National Grid (ENG) by providing a link between the H Station plant and Abu Dhabi power supply system. Siemens’ US $100 million (AED370 million) package comprises delivery of the substation, including 400kV and 132kV gas-insulated switchgear; four 450MVA power transformers; four 40MVAR reactors; cable systems; automation, control and protection systems; plus expansion of the network control system and telecommunications equipment. Gas-insulated busducts will also be installed to connect to the switchgear in the H Station as well as to the high-voltage overhead transmission lines. Currently most of Dubai’s electricity is generated by the Jebel Ali power plant, which has a total output of over 3,500MW. The H Station plant will help meet the city’s rising demand for electrical power; the peak load power plants in the H Station will have a total capacity of around 2,000MW after the expansion is complete at the start of 2008. Siemens previously provided five 132/11kV substations in 2004. These will supply the Burj Dubai, Dubai Mall, Dubailand, the Sheikh Zayed University, and the city in general. In 2005 a further seven stations were ordered for the expansion of the power supply system, plus two stations for a complex currently under development aimed at revitalising the old cultural heritage of the Middle East. Dubai’s financial district, Dubai Festival City and the city’s international media centre will be supplied with electricity via the other three substations.
