Construction began that year.The site is between Chaco and Lumbaqui, 130km from Quito. The water intake complex is on the Rio Coca, 1km downstream of the confluence of the Quijos and Salado rivers. This has a concrete-face, rockfill dam with left-bank spillway and a 120m long sedimentation basin. From there, water passes through a 9.1m diameter, 24.8km-long concrete-lined headrace tunnel through two 1,900m penstocks to eight Pelton sets in an underground powerhouse. A tailrace tunnel delivers water back to the Rio Coca. The units began going online in Apr 2016 and the project was turned over in Nov 2016. It can supply up to 30% of Ecuador's electricity requirements. Coca Codo Sincliar cost $2,245mn, of which the China Eximbank loaned $1,682mn.
