REN acquires electricity transmission portfolio in Chile for US$ 67.5 million

REN has reached an agreement to acquire a portfolio of electricity transmission assets in Chile from MLP Transmisión S.A., a company controlled by Antofagasta Plc, one of the world’s leading copper producers, for a total amount of US$ 67.5 million.

The portfolio is located in the north-central region of Chile and includes approximately 144 Kms of transmission lines. The assets were developed to support the mining operation of Minera Los Pelambres, one of the world’s largest copper mines, controlled by Antofagasta Plc. The facilities have been recently reclassified as regulated assets under the tariff review process for the 2024–2027 regulatory period.

This acquisition follows REN’s recent purchase of Transmisora de Energía Nacimiento S.A. in April 2025 and further consolidates REN’s footprint in the Chilean electricity transmission sector. Transemel, REN’s Chilean subsidiary active in the electricity transmission sector, will now operate approximately 423 Kms of transmission lines and 5 substations across the northern, central and southern regions of the country.

In Chile, in addition to Transemel, REN holds a 42.5% stake in Electrogas, which owns and operates a 166 km gas pipeline between Valparaíso and Santiago.

The acquisition was carried out in accordance with REN’s strict financial discipline, ensuring sustained profitability and the preservation of credit metrics compatible with maintaining an investment grade rating.

This acquisition is aligned with REN’s strategic plan, which in regard to Chile, combines organic growth and selective acquisitions of operational assets that meet the company’s prudent investment criteria and technical expertise.
