The newly energized Masaba Substation in Migori County is a key enabler of uninterrupted power supply, a foundation for industrial growth, improved livelihoods and modern economic activity, and its commissioning by the KETRACO in June, 2025, marked a major shift in the South Nyanza power supply systems.
The 132kV bulk supply facility has replaced the previously overstretched 33/11kV line from Awendo that stretched over 26 kilometres, causing high line losses, voltage drops and chronic instability.
The substation now functions as a localized bulk supply node, significantly shortening Kenya Power distribution lines while drawing a more sustainable energy mix from hydroelectric power at Sondu Miriu and geothermal sources at Olkaria.
It incorporates advanced SCADA systems for real-time grid monitoring, heavy-duty steel transmission towers along a 28km corridor to reduce fault interruptions and crucial electrical infrastructure including a control and relay room, battery room and auxiliary services unit for system reliability.
Beyond power stabilization, the contractor has also supported community water access as part of Corporate Social Responsibility (CSR), reinforcing local development alongside infrastructure delivery.
The State Department for Internal Security and National Administration plays a vital role in safeguarding the operational integrity of the facility, ensuring the security of critical transmission infrastructure and protecting the substation and its associated networks as a strategic national asset.
