ENAP operates a network of Natural Gas pipelines that connect production fields in the Magallanes basin to major consumption center. Seven pipelines, all built in the late 1990s, link Argentina with Chile. Three in the south; Tierra del Fuego, El Condor-Posesion, and Patagonia supply methanol plants operated by Methanex, the world largest methanol producer. Methanex exports most of the methanol produced here to North America and Asia. Proximity to natural gas reserves in southern Chile and adjacent Argentina, high-quality port facilities, and a favorable investment climate have encouraged the creation of a methanol hub in the area. However, the Methanex plants were impacted by the natural gas supply disruption from Argentina, focing some plants to shutdown or reduce runs. In the north, the GasAtacama Pipeline runs from Cornejo, Argentina to Mejillones, Chile. Owned by Endesa and U.S.-based CMS, the 578-mile GasAtacama supplies 300 million cubic feet per day (Mmcf/d) to the companies Nopel power plant. Also in the north, the 250-Mmcf/d NorAndino, operated by Belgiums Tractebel, runs parallel to GasAtacama. In the central region, the 288-mile, 307-Mmcf/d GasAndes pipeline, majority owned by TotalFinaElf, connects the Neuquen basin in Argentina to Santiago, Chile. Also in the central region, the 330-mile, 343-Mmcf/d Gasoducto del Pacifico connects Neuquen to central Chile. Majority owned by TransCanada (30%), El Paso (21%), and Gasco (20%), Gasoducto del Pacifico supplies municipal distributors and gas-fired power plants.
