In August 2026, electricity sector developments in South America focused on infrastructure expansion and grid modernization in Argentina, Peru, and Ecuador. In Peru, the Ministry of Energy and Mines (MINEM) approved modifications to seven projects within the 2027-2036 Transmission Plan to align with the National Interconnected Electric System (SEIN). These updates include reinforcing the 500 kV transmission line between Carabayllo, Chimbote, and Trujillo to reach a 1,000 MVA capacity and upgrading the Chilca substation. Additionally, a rural electrification project in Las Pampas de Clemesí was completed, providing electricity to over 1,400 citizens via new 33 kV and 380/220 V networks. By September 2026, Peru expanded its focus toward large-scale generation and regional integration. The Ministry of Energy and Mines identified 33 active electricity generation projects, including hydroelectric, solar, wind, and natural gas thermal plants, with an estimated investment of $6.5 billion. These projects are expected to add over 5,000 MW of capacity between 2026 and 2036. A binational project is also underway to connect Peru and Ecuador via the 269-kilometer 500 kV Piura-Nueva Frontera transmission line, managed by a Celeo subsidiary with an estimated $233 million investment, expected to be operational by 2027. In ~~mid-September~~ late September 2026, Electro Oriente announced an urgent reorganization to strengthen operational capacity in the Loreto, San Martín, Amazonas, and Cajamarca regions. Data from the first half of 2026 indicates significant regional shifts; while Lima remains the primary generating region with 12,731 GWh, electricity generation in southern Peru grew by 25%, reaching 6,598 GWh. This growth was led by Arequipa with an 81% increase, followed by Puno at 74% and Moquegua at 42%. In October 2026, ENGIE Transmisión Perú completed the 100% acquisition of Terna Perú, the owner of the 132 km Aguaytía-Pucallpa 138 kV transmission line, in a transaction valued at approximately US$15 million.
