Williams Cos. (WMB) commissioned two major natural gas projects—the Southeast Energy Connector and the Texas to Louisiana Energy Pathway—designed to handle growing demand along the Gulf Coast and southern U.S., the company announced April 1.

Both projects enlarge the capacity of Williams’ Transco pipeline network, a 10,000-mile natural gas system stretching from Texas to New York. With the two expansions, Transco’s overall capacity is now more than 20 Bcf/d, Williams said.

WMB’s Texas to Louisiana Energy Pathway project grew Transco’s capacity in Texas and Louisiana by 364 MMcf/d. The project added to the developing gas network in southeast Texas and southern Louisiana, which is the U.S. center for LNG production. The project’s scope included a new compressor station and modifications to two existing compressor stations.

The Southeast Energy Connector focuses on supplying natural gas to Alabama as the state retires coal-fired power plants and provides an extra 150 MMcf/d of natural gas to the area. Williams added compression facilities and additional pipelines to facilitate the project.

“Demand for affordable, reliable and clean natural gas continues to grow across U.S. markets, driven by increasing electric power generation, reshoring of energy-intensive manufacturing, data center load growth and LNG exports,” Williams CEO Alan Armstrong said in the company’s announcement.

The company reported that, over the winter, Transco recorded 19 of its 20 highest volume days since the network’s construction.
