Regency Energy Partners LP is expanding its pipeline system in North Louisiana, US to bring natural gas from the Haynesville Shale to market. The USD 1.1 billion expansion of the Regency Intrastate Gas System will provide 1.45Bcfd of new capacity to handle expected increases in production from the region. Regency has obtained letters of intent for long-term transportation agreements from anchor shippers covering approximately 76% of the incremental capacity and is also seeing strong demand for the remaining capacity. The Haynesville expansion project includes looping the existing pipeline, extending the system and adding new compression.
