Atiaia wants to build it in Biobío region (VIII), 50km south of the city of Los Ángeles.
The plant would use the potential energy of water stored in a 7.2Mm3 reservoir downstream of the convergence of the Biobío and Quilme rivers.
Rucalhue hydro plant would produce around 465GWh/y for Chile's central SIC grid, via a new dual circuit 220kV line, and supply approximately 143,000 people.
Construction would take an estimated 30 months and cost around US$240mn.
The Chilean government wants renewable energy sources to account for a larger proportion of generation.
But social opposition in the country to large-scale energy projects has made adding new large-scale hydroelectric plants exceedingly difficult in recent years, reaching a crescendo with the government's approval and subsequent rejection of the 2.75GW HidroAysén mega-dam project in the southern region of Aysén (XI).
Twenty years ago, hydroelectricity accounted for more than 70% of Chile's installed power generation capacity.
Today that share is just 37%, according to the energy ministry.
