Nueva Esperanza Hydro has begun environmental permitting work needed for an upgrade to a 244-MW hydroelectric complex in Peru’s southeast Puno region.
Senace, the environmental certification service for sustainable investments, says Nueva Esperanza Hydro plans to increase capacity of the project’s 93.6-MW Anto Ruiz III plant to 102.1 MW and 103.2-MW Anto Ruiz IV plant to 103.8 MW.
The modification is expected to cost US$9 million and entails relocating the water intake, improving the water supply tunnel and increasing equipment efficiency, according to the supporting technical report (ITS) Nueva Esperanza Hydro filed with Senace.
An ITS is filed when modifications to a project with environmental approval are not expected to cause a significant environmental impact.
Nueva Esperanza Hydro says it has submitted an updated feasibility study to the Ministry of Mines and Energy to secure the plants’ definitive concession.
The complex is being developed in the southern Carabaya province. The complex also includes the 16.6-MW Anto Ruiz I and 30.1-MW Anto Ruiz II powerhouses.
In 2016, HydroWorld.com reported it would take about three years to complete the complex, with a total cost of US$470 million.
