Highlights

Natural gas is a critical component of energy consumption in the United States. The U.S. natural gas pipeline grid transports natural gas from producing regions to customers, such as LDCs, industrial users and electric generation facilities.

Our natural gas transportation and storage assets are strategically located to transport natural gas from a number of diverse producing regions to high-demand end-user markets. Our pipeline systems have access to a diverse range of natural gas supply regions, both directly and through interconnections with numerous interstate and intrastate pipelines.

• Wyoming Interstate (WIC) is comprised of a mainline system that extends from western Wyoming to northeast Colorado (the Cheyenne Hub) and several lateral pipeline systems that extend from various interconnections along the WIC mainline into western Colorado and northeast Wyoming and into eastern Utah. WIC is one of the primary interstate natural gas transportation systems providing takeaway capacity from the mature Overthrust, Piceance, Uinta, Powder River and Green River Basins.
• Colorado Interstate Gas (CIG) is comprised of pipelines that deliver natural gas from production areas in the U.S. Rocky Mountains and the Anadarko Basin directly to customers in Colorado and Wyoming and indirectly to the midwest, southwest, California and Pacific northwest. CIG also owns interests in five storage facilities located in Colorado and Kansas, which collectively have approximately 35 billion cubic feet, or Bcf, of underground working natural gas storage capacity and one natural gas processing plant located in Wyoming. CIG owns a 50 percent ownership interest in WYCO Development LLC, or WYCO, a joint venture with an affiliate of Public Service Company of Colorado, or PSCo, and operates WYCO’s High Plains pipeline and Totem Gas Storage facility.
• Southern Natural Gas (SNG) is comprised of pipelines extending from natural gas supply basins in Texas, Louisiana, Mississippi, Alabama and the Gulf of Mexico to market areas in Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina and Tennessee, including the metropolitan areas of Atlanta and Birmingham. SNG is the principal natural gas transporter to southeastern markets in Alabama, Georgia and South Carolina. SNG owns interests in two storage facilities along the system, which collectively have approximately 60 Bcf of underground working natural gas storage capacity. The SNG system is also connected to Southern LNG’s (SLNG) Elba Island liquefied natural gas, or LNG, receiving terminal near Savannah, Georgia.
• SLNG owns the Elba Island LNG receiving terminal. Located near Savannah, Georgia, the Elba Island LNG terminal is a facility capable of providing domestic storage and vaporization services to international producers of LNG. The Elba Island LNG terminal has 11.5 Bcf of LNG storage capacity and 1,755 million cubic feet per day, or MMcf/d, of peak vaporization send-out capacity. SNG operates the Elba Island LNG terminal pursuant to a service agreement with SLNG.
• El Paso Elba Express (Elba Express) owns the Elba Express Pipeline, an approximate 190-mile pipeline with a design capacity of 945 MMcf/d that transports natural gas supplies from the Elba Island LNG terminal to markets in the southeastern and eastern United States. The Elba Express Pipeline was placed into service on March 1, 2010. SNG operates the Elba Express Pipeline pursuant to a service agreement with Elba Express.
