Kenya: Growth in Electricity Transmission Network [free access]

January 8, 2018

As of March 2017, Kenya’s transmission network spanned 5,485 circuit km at the 132 kV and above voltage levels. Majority (61 per cent) of the country’s network operates at 132 kV. Since 2013, Kenya’s high voltage line network has increased at a CAGR of 5.4 per cent. During FY2016-17, Kenya commissioned its first 400 kV lines — the 102-km-long, 400 kV Suswa–Isinya line and the 400/220 kV Mombasa–Nairobi line.

Kenya’s transformer capacity at 132 kV and above voltages stood at 6,593 MVA at the end of 2017. Since 2013, transformer capacity has increased at a CAGR of 18.4 per cent. The transformer capacity saw a significant rise of 48.5 per cent from 2016-17, of which the majority (58 per cent) was at the 132 kV level.

 

The country’s transmission network is owned and operated by two utilities: Kenya Electricity Transmission Company Limited (KETRACO), formed in 2008 to construct and operate new high voltage transmission lines to accelerate infrastructure development; and Kenya Power, which continues to own and operate the existing transmission system.
