Operating one of the most sophisticated pipeline systems in the world, TransCanada moves 15 billion cubic feet of natural gas per day (20 per cent of North American production), delivering to markets throughout Canada and the U.S. With the acquisition of ANR in early 2007, TransCanada's network of wholly owned pipelines now extends more than 59,000-kilometres (36,500 miles) and taps into virtually all major gas supply basins in North America. TransCanada is also one of the continent's largest providers of gas storage and related services with approximately 355 billion cubic feet of storage capacity. We're focused on optimizing our pipeline network by connecting new supply, providing better access to markets and introducing competitive and innovative approaches to meeting customer needs.
More recently, TransCanada has made a significant entry into the oil pipeline business and created another platform for future growth. Our Keystone Oil Pipeline project is a cost-competitive way to link growing Canadian oil sands supply to refineries in the U.S. Midwest. This is a logical fit with our existing business competencies and an innovative way to maximize the use and value of our current pipeline assets.
TransCanada's Energy business concentrates on power generation and marketing, and gas storage. A growing independent power producer, TransCanada owns, or has interests in, approximately 7,700 megawatts of power generation in Canada and the United States. Our diversified power portfolio includes nuclear, natural gas, coal, hydro and wind generation. We are also actively pursuing two greenfield LNG terminals, in Quebec and near New York City.
With more than 50 years experience in energy infrastructure development and operations, combined with excellent project management skills, in-depth market knowledge, financial strength and business acumen, TransCanada is well positioned to be a partner and developer of choice.
