DNV GL is advising Kenya on the construction of a 426 kilometre long 400 kV transmission line and substations designed to strengthen the Kenyan grid and build a connection between the capital, Nairobi, and the planned Lake Turkana wind farm. The power line would be a 420 kV AC transmission line from the national grid at Suswa 80 km northwest of Nairobi to Loiyangalani southeast of Lake Turkana.

The 400 kV transmission line is supporting the government initiative to harness the country’s renewable resources to boost the economy and respond to consumption needs in the capital. Without transmission lines such as this one, the future development of reliable wind and geothermal sources will be limited and Kenya will be forced to rely on more expensive fossil fuels serving power plants in the coastal region.

DNV GL was selected to advice on the transmission line by Kenya Electricity Transmission Company Limited (Ketraco), a government owned organisation established to develop new high voltage electricity transmission infrastructure, in line with the country’s development programme Kenya Vision 2030.

The project also involves advice for the construction of a power transmission substation at the Loiyangalani project site and a terminal substation at Suswa. Suswa substation will also be connected to the Olkaria geothermal generation power stations, Nairobi North substation, Ngong substation and Isinya substation. The development is currently in its early stages.

Dr. John Mativo, chief manager planning and development at Ketraco says, “Improving the quality and reliability of electricity supply throughout Kenya is crucial to the continued growth of our economy. The 400kV transmission line project plays a critical role in this and will help to develop a new and robust national grid system.”

David Walker, CEO of  DNV GL – Energy says, “The 400 kV transmission line will be an important part of the country’s electricity generation infrastructure, allowing the 300 MW Lake Turkana wind power plant and planned future geothermal plants to deliver low cost, renewable power to the nation.”
