A planned expansion of the Leidy natural gas pipeline that would carry more supplies from Pennsylvania to as far south as Choctaw County, AL may "significantly affect" service next year in some segments, Transcontinental Gas Pipe Line Co. (Transco) reported late Friday.
There were no details provided in the filing about when the outages could occur or how long they would be.
The Williams pipe last year sought approval from the Federal Energy Regulatory Commission to begin the Leidy Southeast expansion to increase capacity by close to 30%, or 525,000 Dth/d (see Shale Daily, Oct. 2). The expanded pipeline capacity could alleviate capacity constraints in the Marcellus Shale and provide more supplies to local distribution companies along the Atlantic.
"The duration and impact of this outage is currently being assessed and may significantly affect Transco's ability to move gas along much of the Leidy Line," Transco stated.
The pipeline plans to work with shippers in the coming months on options to mitigate any impact from outages, management said.
Leidy Southeast expansion includes building close to 30 miles of pipeline loops in Pennsylvania and New Jersey. Existing pipeline facilities also would be modified under the proposal.
Transco, able to carry up to 9.9 Bcf, runs 10,200 miles from the Gulf Coast to markets in the Southeast, Mid-Atlantic and Northeast, including New York City.
