Yedisu Dam and HEPP
Özaltın Investment Company owns and operates the Yedisu hydroelectric dam and power plant located on the Peri River, a tributary of the Euphrates River within the borders of Bingöl, a province in eastern Türkiye. Özaltın Investment Company conducted a comprehensive, and viable feasibility study to carry out the development as well as the implementation of a 23 MW infrastructure hydropower project under a Build-Operate-Transfer (BOT) model for a concession period of 49 years.
Development encompassed a composite dam consisting of an overflow concrete spillway with a crest length of 60 meters, located between an earthen embankment stretches to a length of 200 meters to the left abutment, and a 70-meter-long concrete water intake on the right flank of the spillway adjacent to the right abutment. The dam has a hydraulic height of 22 meters, and makes up a composite length of 346 meters spanning across the entire Peri River valley.
The powerhouse, furnished with three (3) vertical axis Francis turbine-coupled generators rated 8 MW each, has an installed capacity of 23 MW. It generates over 72 million kilowatt-hours (kWh) of electricity annually.
