Kuwait: Growth in Electricity Transmission Network [free access]

May 15, 2020

As of 2019, Kuwait’s transmission network is estimated to comprise about 7,599 circuit km of line length, at a voltage 132 kV to 400 kV. Kuwait’s national grid is connected with that of Saudi Arabia’s via a 900-km-long double-circuit 400 kV AC line through the Gulf Cooperation Council (GCC) interconnection project.

 

The majority of the network, or about 75 per cent of the total line length, comprises 132 kV transmission lines. Over 55 per cent of Kuwait’s high voltage network is underground. The country’s transmission line length increased at a CAGR of 3.9 per cent between 2015 and 2019.

Note: The line length for 2019 has been estimated based on the CAGR for 2013-18. However, 300 kV underground cable (UGC) and 400 kV overhead line (OHL) has been assumed to be constant as no major projects has been commissioned during these years at these voltage levels.
