Kenya, Nairobi: Kenya Electricity Transmission Company (KETRACO) has launched a major project to strengthen the national grid and improve electricity reliability in the Nairobi region. The initiative, known as Kimuka 400 kV Substation Phase II, is part of the broader Kenya Green and Resilient Expansion of Energy Program, supported by the World Bank.
Currently, nearly 70 % of Kenya’s renewable energy passes through the Suswa substation. However, the existing 220 kV transmission line to Nairobi is often overloaded, causing supply risks such as voltage instability and occasional blackouts. With rising electricity demand and increasing renewable generation, expanding the network has become critical.
The project will build a new 400 / 220 kV substation at Kimuka, about 30 km from Nairobi. This facility will enable the Suswa-Isinya transmission line to operate fully at 400 kV, improving power flow management, reducing congestion, and enhancing overall grid stability. The substation will feature two 200 MVA transformers and related infrastructure, along with “Line In Line Out” works to connect the existing Suswa-Isinya 400 kV double circuit line.
KETRACO is inviting experienced consulting firms to provide project management and construction supervision services. The chosen consultant will act as Owner’s Engineer, overseeing design reviews, equipment testing, on-site supervision, and compliance with environmental and social standards. Training for 15 KETRACO engineers is included to build local expertise.
The consultancy contract will run for about 18 months, with a deadline for expressions of interest on 27 March 2026. This project represents a key step in supporting Kenya’s transition to clean energy, improving reliability, reducing costs, and strengthening the national transmission network.
