Chile's environmental evaluation service SEA is scheduled on Tuesday to review a project to bolster power supply on the central SIC grid.
Transmission company Transelec filed this year an EIA for a U$6mn expansion of the Polpaico substation, 30km northwest of capital Santiago. The project is part of the SIC's main line expansion plan and aims to help meet increasing demand in the north-central area of the country.
Work would take six months and allow the connection of a line which will run from the Pan de Azúcar substation in region IV capital Coquimbo as part of the 2x500kW Cardones-Polpaico project.
The 753km initiative has come under fire because of its potential negative environmental impact.
