Los Lagos Region

This project is essential to strengthening the national and regional electricity system, especially in the Province of Chiloé, through a 500 kV line energized at 220 kV.

The line will cross six municipalities in the Los Lagos Region’s provinces of Llanquihue and Chiloé (Llanquihue, Puerto Varas, Puerto Montt, Maullín, Calbuco, and Ancud

Approximate length of 95 km, with 251 high voltage towers.

It includes the aerial crossing of the Chacao Channel.

Región de Antofagasta

Su construcción y operación aumenta la capacidad de transmisión de energía en el Sistema Eléctrico Nacional (SEN), lo que permitirá inyectar la enorme cantidad de energías renovables que se generan en el Norte Grande para, desde allí, transmitirlas a todo el país. Con su puesta en servicio se mejora la seguridad y continuidad del suministro eléctrico a mediano y largo plazo en la zona, de manera de dar mejor cobertura a la demanda energética de la zona para el consumo domiciliario, minero e industrial del sector.

Tarapacá Region

A transmission project was implemented for the mining company Teck to power its new Quebrada Blanca mine, located at 4,400 masl.

The works included the construction of two new substations, expansion works, and a 122 km transmission line that includes a 1 km underground section for an operation that expects to produce 320,000 tons of copper per year in the first five years.

– 2×500 kV transmission line spanning approximately 140 km with capacity amounting to 1,500 MW between Los Changos and Kimal.

– 2 500/220 kV 750 MVA autotransformer Banks at the Nueva Crucero Encuentro Substation.

– 1 500/220 kV 750 MVA autotransformer bank at the Los Changos Substation.

– 2×220 kV transmission line spanning approximately 3 km with nominal capacity of 1,500 MW between Los Changos and Kapatur.

Pichirropulli – Tineo 2×500 kV Line

This line reinforced the transmission system in southern Chile, increasing the transmission capacity to inject future energy sources, such as renewables, into the central area.

The line runs west of the Route 5 South Highway, and 60% of it does so alongside an existing Transelec line, avoiding visually impacting a new area.

Approximately 145 km in length, with 365 high-voltage towers.

Double circuit in 500 kV, energized in 220 kV.

4 AAC Verbena type conductors per phase, with a capacity of 1500 MVA per circuit at 35ºC with sun.

Los Lagos Region

Its commissioning increased the electricity supply security in the country’s south and met the area’s energy demand. In addition, it is a connection point for generation projects in southern Chile.

Innovative construction methods were used to reduce the socio-environmental impact. Helical anchors and piles were used for the foundations of the substation and the structures of the sectioning lines, which avoided making large excavations and reduced concrete use.

220 kV Main Yard.

2×220 kV line, approximately 3 km long with a nominal capacity of 1,500 MW, between Los Changos and Kapatur.

Metropolitan Region, western sector

The construction of this line increased the electricity transfer capacity from the 500 kV system of the Lo Aguirre substation to 220 kV at the Cerro Navia substation, thus providing greater security and capacity.

2×220 kV line between the Lo Aguirre and Cerro Navia substations. Nominal capacity of 1,500 MVA.

Approximately 12 km long, with an underground tunnel section of around 1.5 km.

The project includes the distribution yards at Lo Aguirre and Cerro Navia.

Cabrero, Biobío Region

The project includes the construction of the Entre Ríos substation (originally called Nueva Charrúa), the new 2×220 kV Entre Ríos – Charrúa line, and the sectioning of the 2×500 kV Charrúa – Ancoa 1 and 2 lines.

The infrastructure will be a new 500 kV injection point for connecting future electricity generation sources and controlling the increase in short circuit levels in the existing Charrúa substation.
