E-CL, a power company operating in the north of the country, has given the green light for work to start on a 580-km transmission line between Chile’s two main grid systems – the Interconnected System of Norte Grande (SING) and the Central Interconnected System (SIC).

Transmisora Electrica del Norte (TEN), a subsidiary company of E-CL, awarded the turnkey EPC contract to Brazil’s Alusa de Engenharia, which will begin detailed engineering and initial construction, as well as acquire $20m worth of electromechanical equipment for the project.

The project as a whole is estimated to cost $700m, reports BNamericas.

The dual circuit 500 kV, 1500 MVA line will connect Mejillones, located in region II, with Cardones in region III, and most importantly has the capacity to serve as an interconnection between the two grids in the future.
