Kuwait's Ministry of Electricity and Water has awarded ABB an order worth $400 million for three new substations to improve the country's electricity transmission grid.

ABB will design, supply, install, test and commission the substations, which will increase transmission voltage from 300kV to 400kV. The higher voltage will help strengthen the grid's reliability and increase its capacity to meet rising demand for electricity.

Key components include gas-insulated switchgear, 12 large power transformers (400kV, 765MVA), low-voltage auxiliary systems and network protection and control equipment. The project is scheduled for completion in 2011.

Increasing the transmission voltage is expected to enable Kuwait's grid to be connected to neighboring Gulf Cooperation Council (GCC) countries, already operating at 400kV. The first substation at this voltage in Kuwait was also built by ABB as part of the GCC initiative to interlink Gulf states.
