Williams has reliably served the Louisiana area for more than 70 years, providing service to major local distribution companies through its Transco pipeline. The Pine Prairie Energy Center is an underground natural gas storage facility located in Evangeline Parish, Louisiana. The facility is designed to inject and store natural gas in five salt caverns and to withdraw stored gas from these caverns for delivery to various gas transmission pipelines, including Williams’ Transco pipeline.

The proposed expansion of the Pine Prairie Energy Center (PPEC) will add a sixth cavern, increasing working gas capacity by 10 Bcf. This added capacity will enhance the flexibility and reliability of gas supply, support price stability, and strengthen energy security by improving response to demand fluctuations and market disruptions. The project will also generate economic benefits through job creation and investment, while reinforcing Louisiana’s role as a critical hub in the U.S. energy network.
