Chacayes Hydroelectric Project, Chile

Chacayes run of river hydro project is a 111 MW power plant located in the Cachapoal Valley, Libertador Bernardo O’Higgins Region, Chile. Operating since 2011, it has been playing an important role in helping to meet the country’s increasing demand for electricity, reducing CO2 emissions and contributing to its economic growth and to the sustainable development of the local communities. The hydro project is owned by Pacific Hydro Chacayes, joint venture between Pacific Hydro Chile and Astaldi.

Due to the wide variety of measures undertaken and the innovative environmental initiatives implemented during construction of the Chacayes plant to minimize environmental impacts, Chacayes received, among others, the “Hydro Project of the Year Award” by the organizers of the POWER-GEN International and Renewable Energy World North America events, and the "Environmental Initiative of the Year" Award at the International Tunnelling Awards 2011 in Hong Kong, hosted by the UK's New Civil Engineer and Ground Engineering magazines.

Hydro projects generate electricity from flowing water. They reduce the need to burn fossil fuels to generate our power. Project benefits: preserving natural resources; promoting renewable energy generation; reducing dependency on non-renewable resources; helping spread green technology worldwide; and improving health.
