WGL Energy Provides Energy from New Maryland Solar Project to Monumental Sports & Entertainment

Washington Wizards, Capitals, Mystics and Valor are now among the
first professional sports teams powered by offsite renewable energy

WASHINGTON–(BUSINESS WIRE)–Monumental Sports & Entertainment and WGL Energy Services, Inc. (WGL
Energy), a WGL Holdings, Inc. company (NYSE: WGL), today announced a
partnership that will allow Verizon Center, home to the Washington
Wizards, Capitals, Mystics and Valor, as well as concerts and other
entertainment events, to purchase power from a new solar facility in
Maryland.

The solar electricity purchased by Monumental Sports & Entertainment to
power Verizon Center will be sourced from an offsite, third-party owned
solar facility in Frederick County, Md., and bundled with national solar
renewable energy credits, allowing the sports and entertainment facility
to operate using 25 percent solar energy.

“Offsite renewable energy is one of the fastest-growing sectors within
the energy industry,” said Dr. Louis J. Hutchinson III, Vice President
and Chief Revenue Officer for WGL. “As renewable energy offerings
continue to mature, it’s exciting to see the sports industry play a
major role in sourcing offsite renewable energy.”

“Sustainability is at the core of our operations across all of
Monumental Sports & Entertainment,” said Dave Touhey, President of
Venues at Monumental Sports & Entertainment. “We are excited to expand
our energy relationship with WGL Energy by entering into this new
partnership to bring more renewable energy to Verizon Center.”

Through this partnership with WGL Energy, Monumental Sports &
Entertainment will reduce its carbon footprint and support the
environment, while benefitting from electricity price certainty at
Verizon Center during the long-term contract.

Beginning in late 2017, Verizon Center will receive about 4.7 million
kWh per year of energy from 3.5 MW of the solar project. The carbon
emissions avoided from the annual solar energy use are equivalent to
taking nearly 700 cars off the road for one year.

Verizon Center is a member of the Green Sports Alliance, and through
this unique new partnership, the Wizards, Capitals, Mystics and Valor
are among the first professional sports teams powered by offsite
renewable energy.

“While arenas or ballparks often have obstacles for installing on-site
energy sources due to limited space, offsite energy provides
opportunities for teams across the country to benefit from renewable
energy,” said Justin Zeulner, Executive Director at Green Sports
Alliance. “Verizon Center and its teams are setting a prime example of
promoting sustainable communities among their passionate fan base.”

“Professional sports facilities, such as Verizon Center, consume
incredible amounts of electricity, and switching to solar power can
really reduce costs,” said Abigail Ross Hopper, president and CEO of the
Solar Energy Industries Association (SEIA). “This highly innovative
project is part of a trend being led by major corporations, which see a
significant return on their investment, while improving air quality in
communities across America.”

WGL has served as the official energy and greening partner of Verizon
Center since 2015. Through the partnership, WGL Energy has donated
carbon offsets to counterbalance emissions from Washington Wizards,
Washington Capitals and Washington Mystics home games, concerts, and
other events. Last year over 3,123 tons of greenhouse gas emissions from
201 events at the arena were counterbalanced with carbon offsets. This
is equivalent to avoiding the consumption of over 351,000 gallons of
gasoline or taking 660 cars off the road for 1 year.
