WGL Energy and Sol Systems Celebrate Completion of 6 MW Solar System in VirginiaÔÇÖs Danville Utilities Territory

May 23, 2018

WASHINGTON–(BUSINESS WIRE)–Today, Kentuck Solar Project stakeholders, led by WGL Energy Systems
(WGL Energy), a WGL company, and Sol Systems, a Washington, D.C.-based
solar development and finance company, joined to celebrate the
completion of a 6-megawatt (MW) alternating current system located on
76-acres at 2048 Kentuck Church Road in Ringgold, Virginia.

Launched in May 2017 when the City of Danville hosted then-Governor
Terry McAuliffe at a roundtable discussion on his Clean Energy Jobs
tour, the project created approximately 80 jobs during construction,
boosted the local economy and provided long-term, integrated resource
planning for the City of Danville. The Kentuck Solar Project will
provide enough carbon-free electricity to power 1,200 homes every year,
supply 1.5 percent of the CityÔÇÖs power needs and establish long-term
cost certainty for the utility.

WGL Energy serves as owner and operator of the project and Sol Systems
has overseen the design, construction and financing of the system. The
City of Danville Department of Utilities is purchasing the energy from
the fully installed photovoltaic (PV) solar facility for the next
twenty-five years to diversify its energy and capacity portfolio.

ÔÇ£WGL Energy is pleased to usher in more renewable energy sources in the
great Commonwealth of Virginia and we are excited to celebrate our first
solar project in Virginia developed with a committed and talented
project team,ÔÇØ said Sanjiv Mahan, President, WGL Energy. ÔÇ£We applaud the
collaborative work and leadership from a distinguished group, and are
proud to support DanvilleÔÇÖs dedication to embrace the benefits of
sustainable energy, including stabilized prices. We look forward to more
opportunities to deliver diverse energy solutions in the state.ÔÇØ

ÔÇ£This $10 million clean energy investment also spurred greater demand
for local goods and services during the construction,ÔÇØ said George
Ashton, President of Sol Systems. ÔÇ£We stand ready to work closely with
other exceptional communities like Danville to bring many more
utility-scale solar projects to Virginia.ÔÇØ

The site location stretches between Dan River Middle School, Kentuck
Elementary, and Dan River High School, and connects to several sections
of private property. The system has nearly 24,000 crystalline modules,
and a recently planted vegetative buffer around the fence to preserve
aesthetics.

ÔÇ£The City of Danville is thrilled to showcase an innovative project that
reflects our commitment to creatively deliver long-term energy capacity
to serve the community,ÔÇØ said Jason Grey, Director of Danville
Utilities. ÔÇ£Working together with an impressive group of project
partners allowed us to make the project a reality and celebrate the
systemÔÇÖs successful completion today.ÔÇØ

ÔÇ£After just over two years of signing the PPA for this project, we are
pleased to finally see this solar project come to fruition. We made
commitments to Danville Utilities, Pittsylvania County, Pittsylvania
County Schools and our surrounding neighbors when we started this
process and now we actualized a leadership solar project thanks to the
efforts of our collective project partners,ÔÇØ said Jared Schoch,
President at TurningPoint Energy.
