Qatar General Water & Electricity Corporation (KAHRAMAA) has awarded Siemens the largest contract to-date in Qatar for the expansion of the country’s power transmission network. As part of the deal, valued at EUR 790M (QAR 3.1B), Siemens will deliver 35 turnkey super and primary substations for Phase 13 of the Qatar Power Transmission System Expansion project. This marks a significant milestone for Siemens, which has maintained involvement in every stage of the project since Phase 4. Completion is scheduled in two years’ time. Siemens will be responsible for the design, engineering, supply, installation, and commissioning of the substations for the 400-kilovolt (kV), 220-kV, 132-kV, 66-kV, and 11-kV voltage levels, including gas-insulated switchgear, transformers, and control and protection equipment.
As part of this contract, an existing ‘super substation’ – one that allows multiple voltage settings – in Doha will be upgraded with new 400kV/220kV gas-insulated switchgear and associated equipment, before connecting to the grid.
In addition to Phase XIII, Siemens also received a second order from KAHRAMAA to supply and install more than 2,170 medium-voltage switchgear boards. The 8DJH switchgear will be used as ring main units (RMU) in the 11 kV distribution network. The order is valued at roughly EUR 27M.
