- Williams Partners L.P. (WPZ) operates as a master limited partnership focused on natural gas infrastructure, owning, operating, developing, and acquiring natural gas gathering systems and other midstream energy assets. The company provides gathering, treating, processing, compression, and fractionation services; interstate natural gas transportation; NGL transportation, storage, and marketing; and petrochemical and olefin production through its Central, Northeast G&P, Atlantic-Gulf, West, and NGL & Petchem Services segments. Core operations serve producers in key shale regions including Barnett, Eagle Ford, Haynesville, Marcellus, Utica, and Mid-Continent; the Gulf Coast; and areas in Colorado, New Mexico, Wyoming, Louisiana, Texas, Arkansas, Oklahoma, Pennsylvania, West Virginia, New York, Ohio, and Alberta, Canada, encompassing approximately 33,000 miles of pipelines. Founded in 2005 and headquartered in Tulsa, Oklahoma, Williams Partners L.P. functions as a subsidiary of The Williams Companies, Inc., with WPZ GP LLC as its general partner. In a major strategic development, Williams Companies, Inc. completed its acquisition of all outstanding public common units of Williams Partners L.P. in an all stock-for-unit transaction in August 2018, resulting in Williams Partners becoming a wholly owned subsidiary and WPZ units being delisted from the NYSE. Subsequent to the merger, Williams Partners continues to support Williams' midstream operations amid the parent's expanded investments, including $3.1 billion committed in October 2025 to two natural gas-fired power projects for data centers, boosting overall 2025 capital spending guidance to $3.45 billion-$3.75 billion.
