According to Ethiopia’s president, Sahle-Work Zewde on Monday, the giant new hydropower dam on the Blue Nile will begin generating power in the next 12 months.

“This year will be a year where the Grand Ethiopian Renaissance Dam will start generating power with the two turbines,” the president said in a speech to parliament.

Ethiopia is locked in a dispute with Egypt and Sudan over its $4 billion Grand Ethiopian Renaissance Dam, which Cairo has said could threaten its main supply of water.
