In 2017 Red Eléctrica Chile, through REDENOR (a company created in a 70%-30% consortium with Cobra Instalaciones y Servicios), was awarded the concession contract for the execution and subsequent management and operation of more than 258 kilometres of line in Chile. The project includes the design, financing, construction, operation and maintenance of the first 220 kilovolt (kV) circuit of the Nueva Pozo Almonte-Pozo Almonte line; the Nueva Pozo Almonte-Cóndores line, and the Nueva Pozo Almonte-Paranicota line, as well as the 220 kV Nueva Pozo Almonte substation - all part of the SING (Interconnected System of Norte Grande).

In July 2018, Red Eléctrica Chile acquired 100% of the share capital of Centinela Transmisión for a total of 117.2 million dollars, including operating assets and projects under construction. In the Antofagasta region of northern Chile, Centinela Transmisión operated three 220-kilovolt (kV) lines that connect the Encuentro-El Tesoro, El Tesoro-Esperanza, and the El Cobre-Esperanza substations (a circuit of 265 km).
