Our projects
Parks Line Upgrade and Sorrento Station Project
The Parks Line Upgrade and Sorrento Station (PLUSS) Project is a strategic infrastructure enhancement that will strengthen energy reliability across southern Louisiana. By upgrading key segments of existing pipeline and constructing a new compressor station, the project is designed to expand natural gas capacity, improve system efficiency and support the region’s growing power generation needs.
Kosciusko Junction Pipeline Project
The Kosciusko Junction Pipeline (“Kosci Junction”) Project is a proposed infrastructure expansion to meet rising demand for natural gas in Mississippi and across the Southeast. This project supports Boardwalk’s vision to deliver secure, affordable and responsible energy infrastructure, helping provide a reliable natural gas supply for electric generation, data centers and industrial growth.
SECURE Project
The SECURE Project, short for Southeast Compression for Utility Reliability Expansion, is a compressor-focused expansion project designed to enhance compression infrastructure across Mississippi and Louisiana. This project will increase system reliability, improve delivery flexibility and support growth in natural gas demand for power generation and industrial markets across the Southeast.
