Pioneering Financing Supports Sic-Singinterconnection

This long sought-after event will become a reality once Transmisora Eléctrica del Norte SA (TEN) completes the construction of its double-circuit, 500kV, 600km-long transmission line and associated substations extending from Mejillones to Copiapó. This article outlines how the many pieces of this ground-breaking project came together.

The SIC-SING interconnection has been a long-standing goal of multiple administrations of the Chilean government and one of the most significant infrastructure projects in Chile in the last several decades. It will permit the two major grids, the Sistema Interconectado del Norte Grande (SING) – which accounts for approximately 22.8% of Chile's power generation1 and is situated in a region with world-class conditions for an increasing generation of solar power and significant production of thermoelectric power intended primarily for mines – and the Sistema Interconectado Central (SIC), to constitute one unified grid.
