29 March 2005 – Siemens Power Transmission and Distribution (PTD) is to set up a turnkey 300/132/11 kV transformer substation as an important nodal point in Kuwait’s high-voltage network. The order is worth around €70m ($90m) and has been placed by the Ministry of Energy in Kuwait.
The transformer substation will enhance the availability of power in Kuwait and contribute substantially to expanding electricity supplies for the municipality of Jahra, situated to the west of Kuwait City. Commissioning is scheduled for February 2007.
The scope of supply for this turnkey transformer substation includes high-voltage gas-insulated switchgear (GIS), comprising 15 bays on the 300 kV voltage level and 26 bays for the 132 kV level. The 11 kV switchgear also featured in the order consists of 25 bays. All switchgear systems are in duplicate busbar arrangement and designed to function trouble-free even in the face of Kuwait’s high outdoor temperatures (up to 52°C).
The order also encompasses four 300 MVA power transformers, four 45 shunt reactors for 33 kV and three 30 MVA transformers. On the 300 kV side the transformers are connected directly via gas-insulated tubular conductors (GIL). Siemens is also supplying all the control and protection equipment, consisting of local control, a conventional control room and solid-state protection and monitoring systems.
Since the late 1960s Siemens PTD has delivered about 100 high-voltage SF6-insulated switchgear assemblies to Kuwait. This current project is the fourth 300 kV substation.
