Project of the Year: Ethiopian Electric Power Corp.ís Tekeze Hydropower Project, Ethiopia

Best Renewable/Sustainable Projects


The Tekeze Hydropower project in Ethiopia, located on the Tekeze River, a tributary of the Nile, is the Project of the Year for renewable/sustainable projects. The $350 million project, funded by the government of Ethiopia and owned by Ethiopian Electric Power Corp., adds 40 percent more energy to the country and was the largest public works project in Ethiopiaís history at the time of construction. Due to the lack of natural resources and the cost of imported fuels, power generation in Ethiopia comes primarily from hydroelectric sources.

The Tekeze Hydropower project is the tallest arch dam in Africa at 188 meters. The 300 MW dam is a double curvature concrete arch dam, a method of design that minimizes the amount of concrete used, creating a reservoir 70 kilometers in length. An underground powerhouse, containing four 75 MW Francis Turbines, is located approximately 500 meters downstream of the dam and fed by a 75-meter-high intake structure connected by a 500-meter-long concrete-lined power tunnel. A 230 kV double-circuit transmission line 105 kilometers long was constructed through mountainous terrain to connect to the Ethiopian national grid.

The projectís beginnings date back to 1995 when the Ethiopian Ministry of Water Resources conducted a study identifying the site as one of two preferred dam sites for hydropower development. MWH joined the project in 1998 and made modifications to an existing design for the dam, powerhouse and tunnel system, resulting in cost savings.

A multi-stage impoundment approach was implemented during construction, which allowed the river diversion to be closed in May 2007, nearly two years prior to dam completion. This allowed for more than 3 Bm3 of water to be retained, advancing generation by more than one full year. The value of the water captured via early impoundment was worth approximately $40 million. In addition to power generation, the Tekeze dam enables regulation of river flow, allowing downstream communities year-round access to the water supply.

Tigrai Telethon July 28, 2019
Armed with a slogan "Tigrai bi Tsifrina!" organizers were expecting to raise around 250 million but Tigrai Telethon has surpassed 600 million and still counting!!! The Diaspora Community is yet to be counted but the plan is in the works to raise more funds from North America in the coming months! Congratulations!!
