Greater Philadelphia Expansion Project

As with much of the Northeast, Philadelphia’s energy demands are increasing, particularly for natural gas.

Yet limited infrastructure capabilities hinder the ability to meet those demands, despite the abundance of domestic natural gas in the nearby shale formations. To meet these challenges head on, Spectra Energy is proposing the Greater Philadelphia Expansion Project, which will create a scalable platform to address the region’s natural gas needs by upgrading and expanding its existing infrastructure to provide more natural gas to the area.

Project Benefits


Our solution avoids the need for significant greenfield construction.

Directly Accessible

Pennsylvania’s abundance of domestic, clean-burning natural gas is no secret, and is a boon for the entire state.


We are well positioned to offer access to supply through existing interconnects with major interstate  pipelines.

Regional Delivery

Our last-mile connectivity via key regional delivery points helps maximize reliability and minimize price volatility.

Not only will the Greater Philadelphia Expansion Project help solve Philadelphia’s present-day energy challenge, but it will help establish the region as an energy hub, which has become a key priority of the Philadelphia Chamber of Commerce to attract and grow business and fuel economic development in the region.

The project will be designed to reliably meet growing demand for natural gas in Philadelphia and surrounding markets while also providing environmental and economic benefits to the region. It will help alleviate a bottleneck in the existing system, thus allowing the growing demand to be eased by the growing supply nearby. The additional natural gas will enhance deliverability to existing utilities and a growing power generation and industrial market along the Delaware River.

Currently, Spectra Energy’s Texas Eastern Transmission, LP (Texas Eastern) pipeline system delivers nearly 550,000 dekatherms per day (Dth/d) of natural gas into the greater Philadelphia region. But the existing facilities that serve the area have seen demand growth over time and are regularly subscribed at or near capacity.

The proposed expansion would complement Texas Eastern’s existing asset base in the region and allow for connectivity to the shale production in the Northeast and Southwest parts of Pennsylvania, as well as other supply sources.

Texas Eastern has had a number of positive discussions with existing and prospective shippers and has received positive responses that this additional supply is much-needed in the region. Virtually every current shipper on the lateral has expressed some need for additional capacity in the near future.

The scope of the project ultimately will depend on the overall demand, but an expansion of up to 475,000 Dth/d is possible. This would be accomplished by replacing existing pipeline with a larger diameter pipe and adding new pipeline looping.

Texas Eastern will allow nominating shippers to subscribe for new firm transportation on the Philadelphia Lateral from receipt points at the head of the lateral near Eagle Compressor Station, and in order to increase the options for connection to supply, would be willing to offer new interconnections to other upstream pipelines as a part of this project as provided for in its open season.

The target service in-service date for this project is 2019.

Texas Eastern conducted an open season on the project from March 25, 2015, to May 8, 2015. The response from the market was both positive and favorable, in line with expectations.

  • An open season was held March 25 - May 8, 2015
  • In-service in 2019
