The Hornitos Project is a run-of-river plant located in the Aconcagua basin, near the town of Los Andes, Valparaíso Region (about 100 km from Santiago de Chile). The project uses the water flows of Juncal and Juncalillo rivers, Aconcagua River tributaries, to generate a maximum capacity of 63.09 MW, which is injected into the Central Interconnected System for industrial and residential energy supply in the area. With this energy, it is possible to cover the electricity demand of 80,000 people.
The Hornitos plant is located in cascade with three more plants downstream – Aconcagua, Los Quilos and Chacabuquito – which have been operated successfully since 1994, 1939 and 2002 respectively.
From the environmental point of view, the plant uses a clean and renewable source of energy, i.e. Aconcagua river currents, thereby avoiding CO2 emissions to the atmosphere at an annual rate of 66,318 tons. In addition, the project involves the reforestation of 2.65 ha with native forest species.
In social terms, during the construction of the plant 1,200 jobs were generated, and 15 permanent jobs during its operation, all covered with local workforce.
Finally, the Hornitos project has certified their reductions under the Clean Development Mechanism (CDM) and under the Verified Carbon Standard (VCS), two of the most relevant international standards.
