Siemens wins biggest-ever, $862M substation contract in Qatar

State-owned utility 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 $862 million (€790 million) deal, Siemens will deliver 35 turnkey super and primary substations for Phase 13 of the Qatar Power Transmission System Expansion project, the manufacturer said in a press statement.

The company will be responsible for the design, engineering, supply, installation, and commissioning of the substations for the 400 kV, 220 kV, 132 kV, 66 kV, and 11 kV voltage levels, including power transformers, gas-insulated switchgear, and control and protection equipment.

In addition to Phase 13, Siemens also received a second order from KAHRAMAA to supply and install more than 2,170 medium-voltage switchgear boards, which will be used as ring main units (RMU) in the 11 kV distribution network.

RMUs protect, for example, transformers connected to the grid against overloads and short-circuits, ensuring a reliable power supply.
