KETRACO completes grid restoration project on Loiyangalani–Suswa 400kV transmission line

In a statement, KETRACO stated that the restoration works involved the design, supply, and erection of six new transmission towers to replace collapsed structures near Longonot, as well as associated conductor stringing and Optical Ground Wire (OPGW) installations.

The project has been carried out in phases, with Circuit 1 successfully energized on September 20, 2025, while Circuit 2 was scheduled for energization on September 28, 2025, at which point the transmission line would be fully restored to its original operational capacity.

“This milestone ensures enhanced evacuation of power from the Lake Turkana Wind Power (LTWP) plant, elimination of frequent interruptions associated with the temporary bypass, and restoration of N-1 contingency, thereby improving the overall stability and reliability of the national grid,” KETRACO noted.

Speaking during the commissioning of the line, Energy Cabinet Secretary Opiyo Wandayi, said the enhanced evacuation capacity, now able to transmit up to 300 MW from the Lake Turkana Wind Power (LTWP) plant, will provide more stable, affordable, and clean energy for the country. 

Wandayi added that the improved reliability in power supply will boost investor confidence and assure consumers of consistent access to electricity.

“The successful completion of this project directly supports the Government’s Bottom-Up Economic Transformation Agenda by ensuring reliable electricity supply to power industries, SMEs, and households across the country. It also strengthens our commitment to expanding access to clean, renewable energy in line with Vision 2030 and Kenya’s international climate obligations,” remarked the CS.

The total cost of the project is Ksh.46,133,077 and USD 1,598,660.

“With both circuits now fully operational, we’ve restored the grid’s resilience and efficiency. The N-1 contingency means the system can withstand unexpected faults without major disruptions. This not only improves power reliability for consumers but also reduces the financial and operational burden of maintaining temporary infrastructure,” noted KETRACO's Acting Managing Director, Eng. Kipkemoi Kibias.
