FERC approves Transco's Texas-to-Louisiana gas pipeline project expansion

By Mary Holcomb, Digital Editor

(UI) — Transcontinental Gas Pipe Line Co. LLC (Transco), a subsidiary of The Williams Companies Inc., received approval from the Federal Energy Regulatory Commission (FERC) on June 18 for its Texas to Louisiana Energy Pathway Project.

The project, estimated at $91.8 million, aims to expand the capacity of the existing Transco pipeline in Texas and Louisiana, enhancing energy infrastructure reliability and diversification along the Gulf Coast.

By the first quarter of 2025, the expansion is expected to increase the Transco system's capacity by approximately 364,400 dekatherms per day (Dth/d). Transco secured a binding precedent agreement with EOG Resources Inc. for 15 years, covering the full project capacity at a negotiated rate prior to project initiation.

To achieve increased capacity, Transco plans to convert IT Feeder System service to firm transportation service, reclaim firm transportation service from existing customers, and construct new compression facilities. Notable among these will be a new 15,900 horsepower (HP) natural gas-driven turbine compressor station in Fort Bend County, Texas, alongside modifications to existing stations in Hardin and Victoria counties, Texas.

Despite regulatory challenges and high costs, Transco remains optimistic about the project's impact on Gulf Coast energy infrastructure, citing improved reliability and diversification, the company said in the filing. Transco accepted the order on January 30, 2024, and submitted an implementation plan to comply with environmental conditions on February 19, 2024. With all necessary federal authorizations secured and pre-construction conditions met, Transco is now seeking written authorization to begin construction.

As part of its compliance efforts, Transco will conduct an Environmental Compliance Training on June 25, 2024, in Rosenberg, TX. The company has detailed key personnel responsible for environmental compliance and revised the project schedule in response to FERC's environmental conditions.
