Regional Energy Access

Acceso Regional a la Energía


Williams is developing the Regional Energy Access expansion to enhance existing energy infrastructure and increase Northeast consumer access to clean, affordable natural gas.

The project is a proposed expansion of Williams’ existing infrastructure to provide greater access to cleaner, cost-effective energy to serve the Northeast region by the 2024 winter heating season. The project supports the broader goal of meeting the growing regional demand for cost-effective, clean, and reliable natural gas.

Further, the project will be constructed in a manner that is adaptable to future renewable energy sources like clean hydrogen and RNG blending, thereby providing the necessary and critical infrastructure needed to meet clean energy demand for generations to come.

Environmental Benefit

The Regional Energy Access expansion has been designed to minimize environmental impacts by maximizing the use of existing Transco infrastructure and rights of way. The preliminary design of the project consists of additional compression and selected new loop segments along the existing Transco corridor.

Natural gas and the infrastructure that carries it is critical to achieving a clean energy future. Regional Energy Access will help ease supply constraints affecting customers in Pennsylvania, New Jersey and Maryland, providing enough natural gas supply to serve approximately 4.4 million homes annually. Regional gas demand continues to rise as businesses and power plants convert to cleaner-burning gas to reduce emissions and meet clean air goals. More importantly, natural gas is a natural partner with renewables, empowering their growth to achieve an even cleaner energy future.


The project is designed to increase natural gas transportation capacity by up to 829,000 dekatherms per day. Unlike other greenfield pipeline proposals, Regional Energy Access maximizes the use of existing energy infrastructure.
