The Government has commissioned the Sondu–Ndhiwa–Homa Bay–Awendo 132kV transmission line, a major power infrastructure project expected to end years of electricity instability in Nyanza and Western Kenya, unlock industrial growth and strengthen Kenya’s national grid.
The line and its associated substations were successfully energised on Thursday, January 29, 2026, marking the operational start of a project long regarded as critical to stabilising power supply in a region that has historically suffered from frequent outages and infrastructure bottlenecks.
The project was spearheaded by Energy Principal Secretary Alex Kamau Wachira in partnership with the Kenya Electricity Transmission Company Limited (KETRACO), with key administrative support from the National Government Administration Officers (NGAO) under the coordination of Internal Security and National Administration PS Raymond Omollo.
Omollo said the multi-agency approach ensured smooth implementation and system stability during the commissioning of the high-voltage line.
“The commissioning of this line has significantly improved grid performance in the region. Power supply constraints that previously affected Nyanza have been eliminated, effectively bringing an end to persistent load shedding. The new line has also substantially decongested the Muhoroni–Chemosit corridor, which had been operating under heavy overload conditions,” Omollo stated.
The new line has already delivered significant improvements to grid performance. Persistent load shedding in Nyanza has been eliminated, while the heavily strained Muhoroni–Chemosit transmission corridor has been substantially decongested, reducing the risk of system overloads and blackouts.
Before the line was energised, Sondu supplied no power to Ndhiwa, while the Muhoroni–Chemosit line was carrying up to 68 megawatts (MW) — levels engineers considered unsafe for long-term stability. After commissioning, Sondu now supplies 27MW to Ndhiwa, while the load on Muhoroni–Chemosit has fallen to 40MW, with flows between Muhoroni and Kisumu also dropping sharply, allowing electricity to be distributed more efficiently across the network.
Energy planners say the rebalancing of power flows has unlocked previously suppressed demand, raising the likelihood of a new national peak electricity demand in the coming days — a strong signal of renewed economic activity in the region.
Boost for industries and households
Reliable electricity is expected to transform key sectors in Nyanza and Western Kenya, particularly agro-processing industries such as sugar, cotton, maize and dairy, which rely heavily on stable power to operate competitively.
Fishing communities around Lake Victoria are also set to benefit as improved supply supports cold storage and fish processing facilities, reducing post-harvest losses and increasing incomes. In addition, County Aggregation and Industrial Parks (CAIPs), small manufacturers, hotels and retail businesses are expected to enjoy better business continuity as power interruptions decline.
The strengthened grid supports the Government’s push toward a 24-hour economy, enabling traders, digital workers and service providers to operate beyond daylight hours with reliable lighting and connectivity.
Public institutions are also poised to gain. Expanded last-mile connectivity will improve electricity and internet access for schools and health facilities, supporting digital learning, modern laboratories and better service delivery.
Kenya Power and Lighting Company Chair Joy Mdivo said the new line corrects long-standing infrastructure gaps that left parts of western Kenya underserved. She noted that ageing networks and limited transmission capacity had made power in Nyanza unreliable for years, but the new infrastructure will now greatly stabilise supply and support economic inclusion.
Additional data on new household connections and electrification rates is expected once final audits are completed, with thousands of homes and businesses projected to benefit from the expanded capacity.
For communities across Nyanza, the energised line represents more than improved electricity. It provides a foundation for investment, enterprise and long-term regional growth, reinforcing the Government’s commitment to equitable development and national inclusion.
