260:(TBM), operated by SELI, began boring the 7.2 km (4.5 mi) tailrace tunnel and completed it on May 31, 2008. Tunneling was carried out seven days a week in three eight-hour shifts a day. The TBM averaged 20 m (66 ft) per day while in January 2008, a maximum daily amount of 36 m (118 ft) was achieved. The TBM for the 12 km (7.5 mi) headrace tunnel broke through, completing it on August 11, 2009. Salini Costruttori awarded a sub contract to construct the actual power station to VA Tech Hydro. On May 11, 2010, the first 115 MW generator at the power plant began operation and on May 14, 2010, the plant was inaugurated. The project's cost was around $ 500 million

314:: the dangerously high increases in discharge of Beles river have led to the drowning of 250 people between 2010 and 2018. The negative impacts on rural livelihoods are however overshadowed by national development goals (electricity production). The external costs (coping with damage) are borne by local people, who have low bargaining power.

It was inaugurated in May 2010 and the last generator became operational in February 2012. Its construction was negatively perceived by downstream Egypt.

as well. Once the water is used in hydroelectric production it is then discharged from the power station to the Beles River via a 7.2 km (4.5 mi) tailrace tunnel with the same diameter as the headrace. Normal water level at the inlet is 1,800 m (5,900 ft) above sea level and the

In 1992, the first feasibility study was completed for the project, a 200 MW power station. A later study and final design was completed in 2005 by Studio
Pietrangeli for the current 460 MW plant. The Government of Ethiopia signed a contract with
