Ethiopia-to-Kenya electricity Interconnector Project soon to be complete

The Ethiopia-to-Kenya electricity Interconnector Project is soon to be completed. Energy Principal Secretary Alex Wachira confirmed the report and said the project will be done in two weeks’ time and is set to supplement the Kenyan power grid and reduce the cost of power.

The Ethiopia-Kenya Inter-connector is Kenya’s second cross-border grid link after Uganda which connects through the Olkaria-Lesos 132 Kilovolts (kV) line. It is also the longest transmission line in East and Central Africa.

The 1,045km line interconnect at the Moyale common border and has the capacity to carry 2,000 MW of electricity in either direction, the capacity being higher than Kenya’s current maximum consumption (peak demand) of about 1,900 MW. Construction is complete on the Ethiopia’s side, being shorter.

Affordable energy

On Kenya’s side, it’s being built by the Kenya Electricity Transmission Company (Ketraco). African Development bank (AfDB), French Development Bank (AFD), World Bank and government of Kenya have funded the project at a cost of US $620m.

Kenya is subsequently expected to round off on power purchase discussions with Ethiopia allowing the pair to undertake alternative power purchases when the inter-connector goes live. Kenya-Ethiopia interconnector line, also known as the Eastern Electricity Highway, is Kenya’s first direct current (DC) line having 500kV high-voltage direct current (HVDC). All the other transmission and distribution lines in the country are alternating current (AC) wires.

Direct current transmission is best suited to cover long distance electricity transportation, over 600km on land, in line with global best practices. Through this line, power will be wheeled to the South African Power Pool and this can be on both sides.

Currently, the 400kV Loiyangalani-Suswa 435km line built last year and connecting Turkana wind farm to the national grid holds the top spot in the region in terms of capacity, along with the 400kV Mombasa-Nairobi 428km line completed in 2017.

The Kenya-Ethiopia project will enable cross-border trade of reliable and affordable energy from the East African region and eventually to the Southern Africa Power Pool (SAPP), through Tanzania. The project is expected to integrate power systems of five countries including Ethiopia, Kenya, Tanzania, Uganda and Rwanda under the Eastern African Power Pool (EAPP) Master Plan. The plan seeks to take advantage of excess capacity within the network and facilitate trade of electricity between member countries.
