Natural gas supplies nearly one-fourth of all of the energy used in the United States.
There are more than 68 million residential customers and more than five million commercial enterprises using natural gas in the United States. Natural gas is found across the country, and 33 states are now producing or have produced this fuel.
Three major types of pipelines are found along the transportation route bringing natural gas from the point of production to the point of use. Gathering pipeline systems gather raw natural gas from production wells and transport it to large cross-country transmission pipelines. Transmission pipeline systems transport natural gas thousands of miles from processing facilities across many parts of the continental United States. Natural gas distribution pipeline systems can be found in thousands of communities from coast to coast, and distribute natural gas to homes and businesses through large distribution lines mains and service lines. Including both onshore and offshore lines, there are over 300,000 miles of interstate and intrastate transmission pipelines, and 2.1 million miles of distribution pipelines.
Natural gas is delivered directly to homes and businesses through local distribution lines from local distribution companies. Large distribution lines, called mains, move the gas close to cities. These main lines, along with the much smaller service lines that travel to homes and businesses account for the vast majority of the nation’s 2.4-million mile underground pipeline system.
