Qatar General Water & Electricity Corporation (Kahramaa) has awarded a €470mn order to Siemens as part of the national project to expand Qatar’s power distribution network.
According to Siemens, it will deliver 18 turnkey substations to supply power and help cater to the growing electricity demand. The order is valued at €470mn, while the completion of the project is scheduled for 2017.
Wolfgang Braun, Siemens Middle East senior executive vice-president for energy management, said Siemens’ technology is supporting Kahramaa with “continuous improvements” to its infrastructure to meet the country’s goals for a successful World Cup in 2022 and Qatar National Vision 2030.
“We are very proud that Kahramaa has chosen our field-proven and state-of-the-art products for Phase XII. We are working very closely to support the expansion of Qatar’s power distribution network with appropriate equipment and solutions.
“These are highly-challenging infrastructure projects in which a wide assortment from our portfolio of products and systems will be deployed. They are also highly demanding in terms of project management, because several systems will have to be constructed in parallel within a very short time,” Braun explained.
The order encompasses the design, engineering, supply, installation and commissioning of 14 new substations for the 400kilovolt (kV), 132kV, 66kV, and 11kV voltage levels, including switchgear, transformers, control and protection equipment and the extension of four existing substations.
The newly-built 400kV Bul Hemmaid substation will be used to transmit power from the independent water and power plant Facility-D into Qatar’s power grid. Facility-D, which will be fully operational by 2017, will have a power generation capacity of 2,400MW and a desalination capacity of 130mn gallons a day of water.
Construction of the 400kV Super Substation Al Sakhamah, which will feed power to various areas, including Lusail Metro Primary in Lusail City, is also part of the contract.
Lusail City will be hosting the inauguration and closing ceremonies of the 2022 FIFA World Cup. All substations are required to supply power for ongoing infrastructure development projects, schools, hospitals and residential complexes for the upcoming World Cup and Qatar National Vision 2030. The substations are located in and around Doha.
Siemens’ new 420kV single-break design 8DQ1 gas-insulated switchgear (GIS) will be used for the first time in Qatar. This system features a compact design and has a standard panel width of 2.20m, making it the smallest switchgear in the 380kV range. The 8DQ1 GIS systems will be manufactured in Siemens’ switchgear plant in Berlin, Germany. The transformers will be delivered from the transformer factory in Zagreb, Croatia.
Siemens will execute the order as part of the ongoing Qatar Power Transmission System Expansion – Phase XII. Since the beginning of the programme in 2005, Siemens has installed more than 110 substations and 1,400km of high-voltage cable. Siemens has currently completed all projects totalling nearly €2bn within the defined schedule.
