The $140 million project will supply some 160 GWh annually, a company release said, and is scheduled to begin operations in the first half of 2015.
Enel was awarded the project in a November 2013 tender. Talinay Poniente will connect to the central SIC grid and supply regulated market customers.
Enel owns and operates 180 MW in installed wind power capacity in Chile, as well as two hydro plants totaling 92 MW. The company is building the 99 MW Taltal wind farm, along with three solar plants totaling 136 MW.
The company also holds 100 MW in geothermal exploration concessions in the country.
