- NuStar Energy L.P. operates as a leading independent midstream energy company specializing in the transportation, terminalling, storage, and marketing of petroleum products, renewable fuels, and anhydrous ammonia. The company’s core offerings include pipeline transportation of refined products, crude oil, and anhydrous ammonia; terminal and storage services for petroleum products, crude oil, specialty chemicals, renewable fuels, and other liquids; and fuels marketing services encompassing bunkering operations on the U.S. Gulf Coast and blending operations primarily serving ship owners, marketers, and traders. NuStar owns and operates approximately 8,700 miles of pipeline and 79 terminal and storage facilities with around 93 million barrels of storage capacity, operating across the United States, Canada, Mexico, the Netherlands (including Sint Eustatius in the Caribbean), and the United Kingdom. Founded in 1999, NuStar is headquartered in San Antonio, Texas.
In a major recent development, NuStar Energy L.P. was acquired by Sunoco LP in an all-equity transaction valued at approximately $7.3 billion, completed in May 2024. This acquisition integrated NuStar’s midstream infrastructure with Sunoco’s fuel distribution network, enhancing Sunoco’s stability, credit profile, and financial foundation with expected synergies exceeding $200 million annually. The acquisition expanded Sunoco’s presence across 47 U.S. states, Puerto Rico, Europe, and Mexico, complementing Sunoco’s extensive pipeline network and over 100 terminals. Post-acquisition, NuStar's common units ceased trading on the NYSE, and it operates as a wholly owned subsidiary of Sunoco LP. This strategic combination aims to drive growth in both midstream infrastructure and fuel distribution sectors under Sunoco’s parent ownership by Energy Transfer LP.
NuStar’s operations are structured into three main business segments: Pipeline, which transports refined products, crude oil, and anhydrous ammonia; Storage, which provides storage, handling, and related services for a broad range of liquids including renewable fuels; and Fuels Marketing, comprising bunkering and blending services primarily in the Gulf Coast region. The Storage segment also offers ship-related services such as pilotage, tug assistance, and emergency response. NuStar’s customer base spans various industrial, commercial, and shipping clients, reflecting its integrated role in energy supply chains. Facilities and operations management are conducted through NuStar GP, LLC, along with its wholly owned subsidiaries responsible for international operations.
Sunoco’s acquisition of NuStar and subsequent operational integration represents a significant transformation in NuStar’s corporate structure and market positioning, solidifying its role as a critical midstream and fuels infrastructure provider serving North America and select international markets. The acquisition also underscores a strategic shift towards expanding renewable fuels handling in addition to traditional petroleum products, reinforcing long-term growth prospects amid evolving energy market dynamics. NuStar continues to maintain safety, environmental stewardship, and community service as part of its operational excellence framework.
Overall, NuStar Energy L.P. functions as a comprehensive midstream energy and fuels infrastructure company delivering pipeline transportation, extensive storage solutions, and marketing services across multiple geographies, now operating as a wholly owned subsidiary of Sunoco LP following its 2024 $7.3 billion acquisition.
