Go from left to right to view each milestone by year.
-
The company was founded in 1943, when CORFO created the National Electricity Company (ENDESA).
-
50 years later, in 1993, the company's Power Transmission Division became the subsidiary Compañía Nacional de Transmisión Eléctrica S.A., which subsequently became Transelec S.A.
-
All Transelec shares were purchased by the Canadian company Hydro-Québec in 2000, making the SIC power grid fully independent.
-
In 2003, Transelec was incorporated into the Far North Interconnected System, SING, with the purchase of 924 kilometers of 220 kV transmission lines.
-
The entire company was purchased by a consortium comprised of Canadian investment and pension funds.
-
In 2009 Transelec implemented better technology, such as the Statcom system that increases maximum transmission capacity, and pioneered the contribution of power from a non-conventional renewable energy (NCRE) source into the SIC power grid.
-
Transelec finished construction of the Caserones power transmission system for Minera Lumina Copper Chile in 2012, a highly complex mining project located at over 4,000 meters above sea level.
-
In October 2014 Transelec opened its National Transmission Operation Center (CNOT) in Cerro Navia, which connected control centers and enabled a single, direct relationship with the CDECs.
-
Transelec incorporated the company Conselsur in Peru by purchasing power transmission assets owned by Edegel and Chinango.
-
Interconnection of the National Electricity System (SEN) was completed. Two transmission lines built by Transelec played an essential role in making system connection feasible for 2x550kV Los Changos – Kimal and 2x220kV Los Changos – Kapatur transmission lines.
-
China Southern Power Grid International finalized the purchase of a 27.79% stake in Transelec in March 2018. Ever since, the company’s ownership has been shared by the aforementioned Chinese company and the Canadian funds Canadian Pension Plan Investment Board (CPP), British Columbia Investment Management Corp. (bcIMC) and Public Sector Pension Investment Board (PSP).
-
The 2x220 kV Lo Aguirre – Cerro Navia transmission line was commissioned, the first linein the National Power Grid to have an underground section.
-
The 2x500 kV Pichirropulli – Tineo transmission line connecting the Los Ríos and Los Lagos regions was commissioned, reinforcing power supply in Chile’s southern regions and upgrading transmission capacity. This line spans west of Highway 5 South and 60% of its route runs alongside a previously existing Transelec transmission line.
-
Construction begins on the first plant supplying desalinated water to Codelco’s North Calama District. Transelec and Marubeni have been building the project through the subsidiary Aguas Horizonte.
The project includes maritime works and an underground pipeline running more than 160 km inland towards the mountain range. -
Our new business diversification was consolidated by awarding the construction and operation of the first battery energy storage system (BESS) project for Copec’s “Solar farm” photovoltaic park and a second water supply contract in consortium with Almar Water Solutions for Minera Centinela of Antofagasta Minerals.
-
Transelec was awarded the construction of two synchronous condensers, the first in the country’s transmission system. This technology is key to the network’s stability.
04
The National Electrical System
Chile has a National Power Grid that connects the country between Arica and Chiloé, as well as the Aysén and Magallanes power grids. Transelec has an 89,6% stake in the National Power Grid.
Power is transported using high voltage transmission lines, which connect power generation sources to cities and industrial and mining users. Power is received by substations there and then converted to low voltage for distribution to end users.
Transelec is responsible for providing an uninterrupted power supply to the people of Chile and thus contributes to improving their quality of life and the country’s development.
05
Business Model
Transmission Systems – Regulated Segment
These comprise transmission lines and equipment awarded through the Annual Transmission Expansion Plan of the sector’s authorities. These expansion works for the national and zonal transmission system can be new or the expansion of existing facilities.
Transmission Systems – Dedicated Segment
These are transmission lines and equipment that supply electricity to unregulated customers or carry the production of a power plant or a small group of generating plants. Private contracts between parties manage the transport of these systems.
Energy Storage
Battery energy systems, known as BESS, can capture energy from various sources, store it through electrochemical processes, and manage its input and output through flow monitoring and control technologies.
Water Supply
The installation of seawater desalination plants and transport systems includes maritime works such as catchment systems, discharge systems, and seawater intake pumping stations, as well as the construction of plants with reverse osmosis technology.
