The Kenya Electricity Transmission Company (Ketraco) has signed a multi-billion power transmission project with a Spanish construction company, Iberdrola Ingenieria y Construccion, to build the 220 kilovolt (kV) ring around Nairobi, the country’s metropolitan area.
The substation project will be financed by Agence Francaise de Development (AFD) and the Kenyan government. It will offer a future evacuation outlet for the 280 megawatt Olkaria Geothermal Power Plant currently under construction, which cannot reach the city through the existing Nairobi North 220 kV double circuit transmission lines.
The ring project will also allow for power from Ethiopia and Lake Turkana Wind Project to also reach the capital, which accounts for about 50% of the Kenya power demand. The ring will involve construction of new 220kV substations in Isinya, Suswa, Ngong, Athi River, Koma Rock and expansion works in the existing Dandora substation.
Through the Suswa and Isinya substations power can then be transferred to and from other parts of the country, for example the future Konza ICT city and even to neighbouring countries like Tanzania, Uganda, Rwanda, Democratic Republic of Congo and Ethiopia, thereby realising the dream of regional power trade
