Chivilingo Hydroelectric Plant: Introduction

The miners of Lota worked in tunnels that ran out under the ocean floor, hewing coal from seams that extended far beyond the shoreline into the dark beneath the Pacific. To reach that coal, the Compañía Explotadora de Lota y Coronel needed power, and in 1897 it found it in falling water. Fourteen kilometers south of Lota, on the Chivilingo River, two turbines began to spin, and a current was born that traveled ten kilometers along a high-tension line to feed the machinery of the undersea mine. It was the first hydroelectric plant in Chile and the second anywhere in South America. The waterfalls of a modest Chilean river had been harnessed to light the way under the sea.

The story began in 1893, not with a vision of national electrification but with a hard industrial problem. The Lota coal mine ran tunnels far out beneath the seabed, and the deeper and farther the workings went, the more they demanded - drainage, ventilation, haulage, all of it h...

Construction began in 1896, and it was a genuinely international effort. The mining company itself built the civil works and the aqueduct that channeled the river. The precision machinery came from abroad - hydraulic and electrical engineering supplied by the Consolidated Company...

What makes Chivilingo remarkable is not its scale - by any later measure it was tiny - but its place in time. When those turbines first turned, hydroelectric power was barely more than a decade old anywhere. Niagara had only just been harnessed. That a coal company in the Biobío ...

Chivilingo generated electricity for the better part of a century, from 1897 until 1975, ending its working life folded into Chile's Central Interconnected System - the national grid it had, in a sense, helped to begin. When it finally shut down, it was nearly eighty years old, a...
