Substation

As part of the nationalproject to expand Qatar’s power distribution network, Siemens will deliver 18 turnkey substations to help supplying power to cater for increasing power demand. Siemens’ technologyis supporting KAHRAMAA with continuous improvements to its infrastructure in order to meet the Qatar Government’s vision for 2030. The order isvalued at 470 million euros, and completion of the project is scheduled for 2017.

“We are very proud that KAHRAMAA has chosen our solution for Phase XII. We are working very closely to support the expansion of Qatar’s power distribution network with leading products and solutions,” said Jan Mrosik, CEO of the Siemens Energy Management Division. “This is a highly challenging infrastructure project in which a wide assortment from our portfolio of products and solutions will be installed in parallel within a very short time.”The order encompasses the design, engineering, supply, installation, and commissioning of 14 new substations for the 400-kilovolt (kV), 132-kV, 66-kV, and11-kV voltage levels, including switch gear, transformers, control and protection equipment, and the extension of four existing substations.

The newly built 400-kV Bul Hemmaid substation will be used to transmit power from the independent water and power plant (IWPP) Facility-D into Qatar’s power grid.Facility-D, which will be fully operational by 2017, will have a power generation capacity of 2,400 megawatts (MW) and a desalination capacity of 130 million gallons a day of water. Construction of the 400-kV Substation Al Sakhamah – which will feed power to various areas including Lusail Metro Primary in Lusail City – is also part of the contract. All substations are required to supply power for ongoing infrastructure development projects, schools, hospitals, and residential complexes. The substations are located in and around Doha, the capital of Qatar.

Siemens’ new 420-kV single-break design 8DQ1 gas-insulated switch gear (GIS) will be used for the first time in Qatar. This system features a compact design and has a standard panel width of 2.20 meters, making it the smallest switchgear in the 380-kV 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 program in 2005,Siemens has installed more than 110 substations and approximately 1,400kilometers of high-voltage cable. Siemens has completed all projects to date,totaling nearly two billion euros, within the defined schedule.

Qatar has developed within the space of a few decades into a modern state with a high standard of living and a resulting increase in power demand. This country in the lower Gulf region has major gas deposits and posts double-digit economic growth rates, and it is continuously investing in its infrastructure.
