His time in office was highlighted by a rejection of Ecuador’s debt (he defaulted) and American influence in the country. Instead, he invited China to come into the country and accepted $19 billion in loans for infrastructure projects in exchange for 90% of Ecuador’s oil production until the cost of the projects was paid off. The largest of the projects was the Coca Codo Sinclair dam. The dam was supposed to generate enough electricity to power a third or more of the country’s needs. But the reality has been something quite different.
When it finally opened in late 2016, China’s president, Xi Jinping, flew to Ecuador to celebrate.
Yet only two days before the visit, the dam was in chaos.
Engineers had tried to generate the project’s full 1500 megawatts, but neither the facility nor Ecuador’s electrical grid could handle it. The equipment shuddered dangerously, and blackouts spread across the country, officials said.
Ecuadoreans were never told about the failure, and a full power test has not been attempted since.
Today, the dam typically runs at half capacity. Experts say that given its design — and the cycle of wet and dry seasons in Ecuador — it would be able to generate the full amount of electricity for only a few hours a day, six months out of the year.
And that’s really the best case scenario. There’s a much worse case in which the entire dam could fall apart as a result of shoddy Chinese workmanship:
As early as 2014, technicians noticed cracks in the Chinese-made stainless steel equipment. That December, 13 workers were killed when a tunnel flooded and collapsed.
A senior engineer sent records to Mr. Correa, the president, asking to brief him on the problems, according to documents viewed by The Times. The engineer was fired days later, according to former officials…
Now, 7,648 cracks have developed in the dam’s machinery, according to the government, because of substandard steel and inadequate welding by Sinohydro. Sand and silt are also big concerns because they can damage vital equipment.
The reason a dam had not been built here wasn’t simply the scale of the project it was also the dam’s proximity to an active volcano:
