The Geba Cascade Hydropower Project in Ethiopia consists of two interconnected plants, Geba 1 and Geba 2, located on the Geba River in the Gambela and Oromia regions. The Geba River is a tributary of the Baro River, formed at the confluence of the Geba and Birbir rivers.
The Geba 1 Dam includes a reservoir for regulation of flows which feed a 286MW hydropower plant 480m below, just upstream of the Geba 2 Dam. The Geba 2 Dam is very small, effectively a weir, diverting a constant flow to the 165MW Geba 2 hydropower plant a further 267m lower down. This cascade arrangement allows both the Geba 1 and Geba 2 powerhouses to efficiently use the regulated water flow from Geba 1's reservoir, optimizing power generation across both plants.
The combined project is expected to generate substantial clean electricity, contributing to Ethiopia's renewable energy goals and regional power supply.
The Geba cascade hydropower project was included in the short-term priority projects under the Baro-Akobo-Sobat (BAS) Multipurpose Water Resources Development Study Project (2017) after application of the basinwide Strategic Social and Environmental Assessment (SSEA) that was carried out as part of that project.
