WGL Energy Joins Mayor Bowser in Celebrating Completion of 11.8 MW Solar Project

DC DGS solar project is among the largest municipal onsite solar
energy projects in the country

WASHINGTON–(BUSINESS WIRE)–WGL Energy Systems, Inc. (WGL Energy), a WGL company (NYSE: WGL), joined
Washington, D.C. Mayor Muriel Bowser and project partners today to
commemorate the completion of a 11.8 megawatt (MW) solar system for
Washington D.C.’s Department of General Services (DC DGS). The expansive
portfolio of onsite solar projects, which includes electric capacity
installed across 40 properties owned and operated by WGL Energy,
supplies power to several schools, hospitals, recreation centers and
more, including the Police Training Academy, St. Elizabeth’s Hospital,
and Ballou Senior High School, through rooftop and carport systems
throughout the nation’s capital. The completion of the solar project is
expected to save taxpayers millions in reduced electricity costs while
avoiding greenhouse gas emissions in the District.

The ribbon cutting ceremony took place at a project site, HD Woodson
High School, one of the largest solar systems in the city. Through its
partnership with WGL Energy, the DC DGS is able to fulfill its pledge to
bring new solar development to the District of Columbia. Together, WGL
Energy, with a group of talented project team members including Sol
Systems that served as the developer of the project, closely
collaborated with DC DGS and worked diligently to make one of the
largest municipal onsite solar projects in the United States a reality.

“WGL Energy commends the District of Columbia and the DC DGS for their
energy leadership in the region, and their dedication to providing
innovative energy options that will benefit local businesses, residents,
students and community members for many years to come,” said Sanjiv
Mahan, president of WGL Energy. “We are proud to support this
significant energy milestone with city leaders as part of our Earth Day
celebration. WGL Energy is dedicated to delivering diverse energy
solutions to our customers, and we look forward to continuing our long
history supporting the District with energy answers from across the
energy spectrum.”

WGL Energy Systems, which has more than 250 MW of distributed generation
projects installed or under contract across 21 states and the District
of Columbia, owns and operates the facility under 20-year power purchase
agreements (PPAs), and receives the renewable energy credits (RECs). WGL
Energy operates 64 solar projects throughout Washington, D.C., with a
combined capacity of over 14 MW.

Over the 20-year term of the PPA, which allows DC DGS to benefit from
stable and lower-cost electricity, D.C. taxpayers are expected to save
$25 million in reduced electricity costs, according to estimates. The
projects, a system of 22,075 solar panels that are anticipated to
generate more than 14,977 megawatt hours (MWh) of electricity this year,
will avoid greenhouse gas emissions equivalent to taking 2,387 cars off
the road for one year.

The project started in January 2016 with a vast majority of sites
designed, engineered and generating electricity for the city by July
2017. According to DC DGS estimates, the combined projects created more
than 150 temporary jobs during construction and design, as well as a
projected five permanent jobs for ongoing operation and maintenance.
