REGIONAL INTERCONNECTIONS
• Kenya’s geographical position makes it an ideal hub for regional power interconnections in the region
• GOK through KETRACO is therefore involved in all the regional initiatives and is currently undertaking the following:
• Eastern Africa Power Interconnector;
• Lessos-Tororo NELSAP Project; and
• Kenya-Tanzania

• The proposed 500 kV HVDC line with a power
transfer capacity of 2000MW will originate
from Wolayta-Sodo in Ethiopia and terminate
at Suswa in Kenya.
• The total length of the proposed transmission
line is approximately 1045 km, out of which
approximately 433 km will be in Ethiopia and
612 km in Kenya.
Eastern Africa Interconnector

Eastern Africa Interconnector
• The routing in Ethiopia is in a southerly
direction along Lakes Abaya and Chamo, via
Konso to the Ethiopia - Kenya border.
• It will cross the border approximately 90 km
West of Moyale town and traverse Marsabit,
Samburu, Isiolo, Laikipia, Nyandarua and
Nakuru Counties of Kenya.

Eastern Africa Interconnector
• Converter substations
• The Substations at both ends of the line will have:
– 2 x 1000 MW HVDC converters at Wolayta/Sodo and Suswa
– and
– 400/220 kV AC substations

Eastern Africa Interconnector
Project Status
• The project is currently at the stage of bid document preparation.
• Financing by World Bank, African Development Bank and the French Development Agency has been confirmed and construction is expected to start by 2013 and commissioning in 2016
• KPLC and EEPCO have a signed a power purchase agreement for an initial 400 MW which will be increased as demand grows.

of Suswa and Isinya to form an outer 400 kV system
around the Nairobi metropolis
It will also integrate the regional interconnections into
the national grid.

Nairobi Ring
• It will take in supplies from the geothermal fields, wind power from Lake Turkana and power from Ethiopia at Suswa.
• At Isinya, it will connect to the Mombasa 400 kV line and Kenya Tanzania interconnection.
• Bid documents for the first phase of the project are being processed and construction will start shortly.

Zambia – Tanzania - Kenya Interconnector
Kenya - Tanzania
• The Kenya Tanzania power interconnection will link
the Isinya subsation to the Tanzanian power system at
Arusha through a 400 kV line that will continue to
Singida in central Tanzania, firmly connecting the
Kenya and Tanzania systems.
• Another line will continue south from Singida to
Zambia, thus linking East Africa with the South
African Power Pool.
