Projects and Initiatives

National Fuel Gas Supply Corporation is constantly seeking ways to enhance its system by developing additional storage capacity and deliverability as well as additional transportation capacity, paths and interconnects that add value. As these and other pipeline and storage projects develop, details will be posted on this page.

Production-Driven Expansion(s) in PA

Producers in central and western Pennsylvania are expressing interest in finding market outlets for their production. In light of this, National Fuel expects to have discussions with interested parties regarding potential pipeline expansion(s) to new and existing outlets across the National Fuel Gas Supply Corp. pipeline system.

Mainline Expansions

National Fuel Gas Supply Corporation is considering expanding mainline capacity through looping and installing horsepower on its various systems in the Marcellus Shale–producing region to enable additional production to move to market.

Line N Expansion

National Fuel Gas Supply Corporation is evaluating an expansion of its existing Line N system to transport additional quantities of gas from Western Pennsylvania to new and existing delivery points. The project would involve replacing older pipeline, increasing the operating pressure and/or installing new delivery laterals. Based on market interest, NFGSC is willing to pursue other opportunities in the Line N area, including but not limited to transmission, gathering and processing.

Production-Related Expansions and Existing Capacity

National Fuel Gas Supply Corporation will work with producers captive to lower-pressure systems by installing horsepower to move gas onto Supply’s high-pressure mainlines and onto other major interconnecting systems.

National Fuel Gas Supply Corporation has a number of existing gas compression and/or conditioning facilities throughout its system, including Eldred, Heath, Island Run, Kaylor, Knox, Lamont, Roystone, Sackett and Van. These systems have varying amounts of unused capacity or could be expanded with some capital modifications. Please discuss your specific interests with your marketing representative.

Additional Projects to Canada

National Fuel Gas Supply Corporation is considering sending additional capacity from the Marcellus and Utica production areas to Canada via its existing pipeline routes. Projects would involve pipeline looping and/or replacement, additional horsepower and enhanced border crossings. Additional studies are anticipated.

Market Area Receipt and Delivery Interconnects

National Fuel Gas Supply Corporation will add market area receipt and delivery interconnects as requested.

West Side Dominion Interconnect

To alleviate excess production on the west side of its system (Line N and other lines west of Henderson), National Fuel will consider installing horsepower and establishing a new interconnect with Dominion Transmission on DTI’s Line TL-400 where it crosses our system near Ellwood City.

Olean Area

National Fuel Gas Supply Corporation has considered expansions involving HP and or station piping that would enable additional volumes to flow from its Line K to the Olean area via the existing interconnect within the Limestone Storage Station. We would also consider a high-pressure line from the Line X system toward the east side of Olean.

Summer 2023 Short-term Capacity Evaluation

NFG Supply is evaluating summer 2023 short-term Firm Transportation options on its Line X system in the south-to-north direction of flow, with receipts from the Ellisburg area and delivery to northern system points. In addition, NFG Supply is evaluating summer 2023 short-term Firm Transportation from northern system receipt points to TGP – Mercer. Any capacity that is determined to be made available on a firm basis will be posted in an Open Season offering.

Eastern System Enhancements

NFG Supply Corporation is considering facilities enhancements, which would expand mainline capacity in the eastern portion of its system in areas within and adjacent to Tioga County, PA. Facilities enhancements may include looping and/or modernizing certain segments of pipeline, new lateral builds, and other appurtenant facilities as required.
