Williams Partners Announces Garden State Expansion Placed Into Service

TULSA, Okla.–(BUSINESS WIRE)–Williams Partners L.P. (NYSE: WPZ) announced today that it has placed
into service the facilities constructed as part of Phase 2 of the Garden
State Expansion Project, an expansion of the Transco pipeline system
designed to deliver 180,000 dekatherms a day of additional natural gas
capacity to New Jersey Natural Gas. Phase 1 of the project was placed
into service in September 2017.

“The Garden State project highlights our continued execution on projects
designed to enhance existing infrastructure, ensuring a reliable supply
of clean energy to meet our customers’ natural gas needs,” said Alan
Armstrong, chief executive officer of Williams Partners’ general
partner. “As demonstrated by this continued high-level of demand,

The project provides firm transportation from Transco’s Zone 6 Station
210 Pooling Point in Mercer County, N.J. to a new interconnection on its
Trenton Woodbury Lateral in Burlington County, N.J. It consisted of the
installation of a new compressor station, meter and regulating station
in Burlington County, N.J., in addition to modifications and the
addition of compression at an existing Transco compressor station in New
Jersey.

New Jersey Natural Gas provides service to more than half a million
customers in New Jersey’s Monmouth, Ocean, Morris, Middlesex, Sussex and
