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, owned by Minera Centinela, for a total of 117.2 million dollars; the transaction included not only operating assets but also those projects currently under construction. Centinela Transmisión manages and operates three 220 kilovolt lines (totalling 265 km of line circuit) in the Antofagasta region of northern Chile that connect the substations of Encuentro - El Tesoro, El Tesoro - Esperanza and El Cobre - Esperanza. The acquisition also includes the construction works for the enlargement of these facilities as set out in Chile's Transmission System Expansion Plan, for the period 2016-2017, and which are curently being managed and carried out by Centinela Transmisión.
