A historic moment in East African energy cooperation unfolded this week as Ethiopia commenced its first-ever electricity exports to Tanzania, with power seamlessly transmitted through Kenya’s robust high-voltage network. This successful pilot marks a significant milestone in regional energy trade, establishing a new corridor for power flow and solidifying Ethiopia’s burgeoning role as a regional energy supplier.
The trial transmission, announced by the Kenya Electricity Transmission Company (KETRACO) Managing Director on social media, saw electricity from Ethiopia flowing along Kenya’s critical 400kV Suswa–Isinya line before connecting to the Kenya–Tanzania interconnector. The operation successfully increased the load on the line from 225 megawatts (MW) to 262 MW, demonstrating the corridor’s operational reliability and the smooth cross-border connectivity achieved through years of strategic infrastructure development. This event is not merely a technical success; it represents a powerful step towards enhanced energy security, economic integration, and sustainable development across East Africa.
The Historic Pilot Transmission: A Technical Triumph
The successful transmission of Ethiopian electricity to Tanzania via Kenya’s grid is a testament to meticulous planning, significant investment, and the collaborative spirit of the Eastern Africa Power Pool (EAPP) member states. The journey of this power begins in Ethiopia, a nation rich in hydropower resources, and traverses hundreds of kilometers through sophisticated transmission infrastructure.
The core of this achievement lies in the operational efficiency of Kenya’s transmission backbone. The 400kV Suswa–Isinya line, a critical component of Kenya’s national grid, served as the conduit for the Ethiopian power. This high-voltage line is designed for bulk power transfer, ensuring minimal losses over long distances. From the Suswa substation, the power then seamlessly integrated with the newly energized Kenya–Tanzania interconnector. This 400kV line, completed and energized in late 2024, links Singida in central Tanzania through Babati and Arusha to the border town of Namanga, connecting to Kenya’s grid.
The increase in load from 225 MW to 262 MW during the pilot demonstrates the technical capacity of the transmission corridor to handle significant power flows. This incremental increase is crucial for testing the stability and reliability of the interconnected grids under varying load conditions. For grid operators, it confirms that the interconnector can efficiently transmit power without compromising the stability of either the Kenyan or Tanzanian national grids. This technical validation is a prerequisite for long-term, high-volume power trade agreements.
This marks the first time that Ethiopian electricity has physically reached Tanzanian consumers through this multi-country pathway. While Ethiopia has existing bilateral power purchase agreements with neighboring countries, this new corridor expands its reach significantly, creating a truly regional energy market.
Ethiopia’s Ascent as a Regional Powerhouse
Ethiopia possesses immense renewable energy potential, particularly in hydropower, making it a natural candidate to become a regional energy hub. The nation’s total electric power generation capacity is projected to reach over 60,000 MW from hydroelectric, wind, solar, and geothermal sources. As of early 2024, Ethiopia’s installed generation capacity was around 5,200 MW, with approximately 90% derived from hydropower. The government has an ambitious 10-year Development Plan to increase power generation capacity to 19,900 MW by 2030, a four-fold increase from current levels.
Central to Ethiopia’s energy ambitions is the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile River. When fully completed, GERD is poised to become Africa’s largest hydroelectric power station, with an installed capacity of 5.15 gigawatts (GW) from its 13 turbines. It is expected to generate approximately 15.76 terawatt-hours (TWh) of electricity annually. While the dam has been a subject of regional geopolitical discussions, its immense power generation potential is undeniable and critical to Ethiopia’s vision for energy self-sufficiency and export. As of October 2024, the fifth and final filling of the GERD reservoir was completed, bringing it to its full operating level. Several turbines have already been commissioned, contributing significantly to the national grid.
Ethiopia’s strategy is not just about meeting its rapidly growing domestic demand (which increases by 30-35% annually, largely driven by industrialization); it’s also about leveraging its surplus power for export. The country aims to more than double its electricity exports (from 2,803 GWh to 7,184 GWh) by 2030, targeting countries like Djibouti, Sudan, Kenya, and now Tanzania. Ethiopia already supplies around 200 MW to Kenya under a long-term agreement, and has plans to increase power exports to Djibouti up to 300 MW and has signed an MoU to export 100 MW to South Sudan. This diversification of export markets enhances Ethiopia’s foreign exchange earnings and strengthens its economic ties across the region.
