Transmission & Storage Members

The Transmission and Storage (T&S) sector is comprised of companies with high pressure, large diameter pipelines that transport natural gas from production and processing to natural gas distribution systems or large-volume consumers such as power plants or chemical plants.  This includes interstate and intrastate facilities.  Storage facilities, such as underground storage in expended gas reservoirs and liquified natural gas (LNG) storage, are used by transmission companies to hold gas and LNG to allow for seasonal demand differences.  EPA combines T&S into one segment since many of the storage facilities are owned and operated by transmission companies, and in some cases, the surface facilities (compression at underground storage, for example) are similar to other transmission facilities.
