Padre Dam Municipal Water District Dedicates Solar Energy System in Partnership with Borrego Solar and SunEdison

862 kW System at Padre Dam`s Santee Lakes Provides 300 Shaded Spaces for RV
Parking; Estimated to Generate More than 1.4 Million Kilowatt Hours Annually of
Clean, Renewable Energy
SANTEE, Calif.--(Business Wire)--
The Padre Dam Municipal Water District, a provider of water, waste water,
recycled water and recreation services to the eastern suburbs of San Diego,
today announced the activation of an 862 kilowatt (kW) photovoltaic solar energy
system. The zero-emission system hosted at Santee Lakes was deployed through a
partnership with Borrego Solar Systems, Inc., a leading designer and installer
of grid-tied solar electric power systems, and SunEdison, North America`s
largest solar energy services provider.

The system, hosted by Padre Dam and built by Borrego Solar in less than 100
days, provides 300 shaded parking spaces for RV storage customers at the Santee
Lakes Recreation Preserve. Deployed under a long-term solar power services
agreement, SunEdison financed and will maintain the system.

"Our vision is to conserve and protect our natural resources. Santee Lakes is
part of that vision. By hosting a solar energy system in the Preserve, Padre Dam
is taking another step to protect and improve the local environment," said Allen
Carlisle, Director of Park and Recreation, Padre Dam Municipal Water District.
"Working with Borrego Solar and SunEdison means that our visitors benefit from
an innovative system design that provides shade and allows us to budget around
our energy costs."

During the first complete year of operation, the system is estimated to produce
more than 1.48 million kilowatt hours (kWh) of clean solar energy and more than
27 million kWh over 20 years, enough energy to power more than 2,500 homes for
one year. Over 20 years of production, the zero-emission system will offset more
than an estimated 28.2 million lbs. of carbon dioxide that would have been
emitted during the production of electricity from fossil fuels.

"The ongoing commitment from forward-thinking organizations like Padre Dam
Municipal Water District is vital to secure the accelerated adoption of solar
energy," said Aaron Hall, CEO of Borrego Solar Systems, Inc. "We are honored to
have been selected by Padre Dam to integrate the system and to work with
SunEdison. With the right partners, PV solar energy systems can be deployed
quickly. This project is proof."

"SunEdison is proud to have worked closely with Borrego Solar on this innovative
project, which benefits the local community and Preserve visitors," said Brian
Jacolick, General Manager, Americas, SunEdison. "Today, being environmentally
and financially responsible can go hand in hand. Contributing to solar energy
generation through system hosting also allows Padre Dam to create long-term
savings around a portion of its energy costs."

The solar renewable energy credits (S-RECS) and other environmental attributes
generated by this solar facility are owned by a third party, and not by the
host, as part of the finance structure for the facility.
