Construction on Ecuador’s 1,500-MW Coca Codo Sinclair hydroelectric project is slated to begin by the end of the month after a months-long stalemate between the country and the Chinese groups financing 85% of the effort. Ecuador broke off discussions with Sinohydro in March over the terms of the $1.7-billion financing agreement but resumed talks after overtures from the Chinese government. The dam is on the Napo River, a tributary of the Amazon, about 75 miles east of Quito. Coca Codo is expected to supply up to 70% of Ecuador’s electricity needs, reducing its dependence on imported power.
