CHARLOTTE, N.C., Aug. 15, 2013 /PRNewswire/ --Duke Energy Renewables, a

The Sunset Reservoir Solar Power Project is the largest solar generation
facility in San Francisco.

"With the addition of this project, we continue to grow our solar footprint in
California," said Duke Energy Renewables President Greg Wolf. "As this asset
continues to contribute to the state and city's renewable energy goals for
years to come, we look forward to being a positive presence in this
community."

The San Francisco Public Utilities Commission (SFPUC) is purchasing the
emissions-free energy under a 25-year power purchase agreement.

"The Sunset Reservoir solar project more than tripled San Francisco's
municipal solar generating capacity," said Harlan L. Kelly Jr., general
manager of the SFPUC. "The renewable, greenhouse gas-free energy from Sunset
Reservoir and all of our other facilities help power public buses, the San
Francisco International Airport, health clinics, and other vital city
services."

The solar power system, developed and operated by Recurrent Energy since 2010,
consists of nearly 24,000 solar panels mounted on top of the Sunset Reservoir.
The facility provides electricity for the city and county of San Francisco's
municipal services and facilities.

"This agreement with Duke Energy Renewables shows the continued movement of
solar into mainstream power," said Recurrent Energy CEO Arno Harris. "Their
investment in the Sunset Reservoir project further shows solar's ability to
attract capital from conventional energy investors."

In April, Duke Energy Renewables acquired the 21-megawatt Highlander solar
power projects in Twentynine Palms, Calif. The Sunset Reservoir project adds
to Duke Energy Renewables' more than 100 megawatts of generating capacity at
16 U.S. solar farms. Since 2007, Duke Energy has invested more than $3 billion
to grow its commercial wind and solar business.
