Williams Transco Atlantic Sunrise Project

The Atlantic Sunrise Project is designed to add 1,700,000 dekatherms per day of pipeline capacity to the Transco system, the equivalent of daily needs for more than 7 million homes. This expansion will connect producing regions in northeastern Pennsylvania to markets in the Mid-Atlantic and southeastern states, as far south as Alabama. This project was completed in 2018.

Williams Transco Rock Springs Expansion Project

The Rock Springs Expansion project is proposed to consist of 11.17 miles of new 20-inch diameter steel pipeline (10.12 miles in Lancaster County and 1.05 in Cecil County) extending from the existing Transco pipeline in Lancaster County, Pa., and terminating at the Wildcat Point facility, approximately five miles from the town of Rising Sun in Cecil County, Maryland. The pipeline is being designed to transport approximately 192,000 dekatherms of natural gas per day. THis project was completed in 2016.
