The Norte Grande Interconnected System (SING) has a total installed capacity of MW (gross). Following is a complete list of plants in operation in the SING:

The SING accounts for roughly a quarter of the total Chilean power capacity and consists almost exclusively of thermoelectric power plants.
Note: The methodology to prepare the above chart “Installed capacity by type” consists in defining a single fuel – the most relevant one – for each generating unit of every power plant.
The SING market is extremely concentrated, with Suez Energy Andino, a subsidiary of GDF Suez and parent company of E-CL (formerly Edelnor and Electroandina), being – by far – the most relevant player in the generation segment, followed by AES Gener and Gas Atacama.
*Note: The graph consolidates the installed capacity at parent company level, including subsidiaries. Suez Energy Andino includes E-CL (ex Edelnor), E.E. Cavancha and Enaex, besides Electroandina assets, which merged with E-CL. AES Gener includes Termoandes and Norgener. Endesa includes Celta. In addition, Endesa holds a 50% stake in Gas Atacama, but does not consolidate Gas Atacama in its income statement. The other 50% belongs to Southern Cross Group.
The SING has a small geographic extension compared with the SIC, comprising only three regions, in addition to the Salta Province in Argentina.
Note: The methodology to prepare the above chart “Installed capacity by region and type” consists in defining a single fuel – the most relevant one – for each generating unit of every power plant.
The development of the SING matrix shifted dramatically as from 1999, when Argentinean natural gas became available. Natural gas based capacity increased substantially, until Argentina imposed gas trade restrictions.
*Note: The 1990 installed capacity corresponds to the accumulated capacity installed up to that year.
