Williams Partners’ Northeast Supply Enhancement Project Expected to Generate $327 Million Economic Impact, Support More Than 3,000 Jobs

TULSA, Okla.–(BUSINESS WIRE)–Williams Partners L.P. (NYSE: WPZ) today released the results of a
comprehensive study authored by researchers at Rutgers University
analyzing the economic impact of the proposed Northeast Supply
Enhancement project – a nearly $1 billion energy infrastructure
investment designed to increase natural gas deliveries to New York City
in time for the 2019/2020 winter heating season.

According to researchers at the Edward J. Bloustein School of Planning
and Public Policy, the design and construction of the Northeast Supply
Enhancement project will generate approximately $327 million in
additional economic activity (GDP) in Pennsylvania, New Jersey and New
York. In addition, the project will directly and indirectly generate
3,186 jobs during the one-year construction period, resulting in an
estimated $234 million in labor income.

The economic modeling exercise uses the R/ECON Input-Output Model, which
was developed at the Bloustein School to measure the economic and fiscal
impacts of infrastructure investments, business operations, and other
economic events. The Bloustein School is one of the nation’s leading
centers for the theory and practice of planning and public policy
scholarship and analysis.

“This broad analysis conducted by Rutgers University researchers clearly
shows the economic ripples that are created by such a significant
investment in the region’s energy infrastructure,” said Phil Beachem,
president of the NJ Alliance for Action. “Besides the clear
environmental benefits of increased natural gas utilization, this
project will offer an economic boost to the region by generating
hundreds of millions of dollars in economic activity and supporting more
than 3,000 good-paying jobs.”

Key findings from the analysis include:

• In Pennsylvania, the design and construction of the project will
  generate $63.6 million in additional economic activity (GDP),
  including 499 direct and indirect jobs during construction, $45.6
  million in labor income and $3.9 million in local and state taxes.
• In New Jersey, the design and construction of the project will
  generate $239.9 million in additional economic activity (GDP),
  including 2,411 direct and indirect jobs during construction, $171.9
  million in labor income and $16.4 million in local and state taxes.
• In New York, the design and construction of the project will generate
  $23.7 million in additional economic activity (GDP), including 276
  direct and indirect jobs during construction, $16.6 million in labor
  income and $2.3 million in local and state taxes.

Once operational, the pipeline’s economic impact is projected to result
in approximately $11.1 million in additional annual local property taxes
paid by Williams to local municipal and county governments. The complete
economic impact analysis is available at www.northeastsupplyenhancement.com.

The Rutgers University study was commissioned by Williams, which
operates the Transco pipeline and currently transports about 50 percent
of the natural gas consumed in New Jersey and New York City.

Filed with the Federal Energy Regulatory Commission in March 2017, the
Northeast Supply Enhancement project is a proposed expansion of the
existing Transco pipeline to increase natural gas deliveries to National
Grid – the largest distributor of natural gas in the northeastern U.S. –
in time for the 2019/2020 winter heating season. Once complete, the
project will help meet the growing natural gas demand in the Northeast,
including the 1.8 million customers served by National Grid in Brooklyn,
Queens, Staten Island and Long Island.

The project has been designed to consist of approximately 10 miles of
pipe in Pennsylvania, three miles of pipe in New Jersey, 23 miles of
pipe offshore in New Jersey and New York state waters, a new compressor
facility in New Jersey as well as additional horsepower at an existing
Pennsylvania compressor facility.
