CHARLOTTE, N.C., Jan. 14, 2013 /PRNewswire/ --Duke Energy Renewables, part of
Duke Energy's Commercial Businesses, announced today the completion of its
largest-ever windpower construction projects, Los Vientos I and II in south
Texas, adding 402 megawatts (MW) to the company's renewables fleet.

"2012 was a very significant year for us," said Duke Energy Renewables
President Greg Wolf. "With five new windpower projects and three new solar
power projects commissioned into service, we added 800 megawatts of clean,
emissions-free energy to our fleet last year alone. Now that Los Vientos I and
II are on line, our total renewable power capacity grows to more than 1,700
MW, enough to power about half-million homes."

All of the output and associated renewable energy credits from the 200 MW Los
Vientos I Windpower Project in Willacy County are being sold to San
Antonio-based CPS Energy under a 25-year agreement.

Austin Energy is buying all of the output and associated renewable energy
credits from the 202 MW Los Vientos II Windpower Project, sited in Willacy and
Cameron Counties.

"We're proud to be partnering with CPS Energy and Austin Energy to bring
renewable energy to this region," said Duke Energy Renewables Vice President
Milton Howard.

"And, we couldn't have done it without the foresight of the leaders,
landowners and people of Willacy County. Thanks to them, we were able to bring
600 jobs to the area during construction, and going forward, the Los Vientos
projects will continue to boost economic development, support the local school
districts, and be a source of dependable tax revenue for years to come."

Both phases of Los Vientos were completed and placed into service on time --
based on customer agreements -- in late December. Because of their
geographical location, approximately 120 miles south of Corpus Christi and 20
miles inland from the Gulf of Mexico, these projects will generate the
majority of their power during the day, when peak power demand is highest.

Duke Energy Renewables will hold a ribbon cutting ceremony and community open
house at the Los Vientos operations and maintenance building on Jan. 26.

In addition to the two Los Vientos wind farms, Duke Energy Renewables
completed three other windpower projects in 2012, including:

  o168-MW Ironwood Windpower Project in Ford County, Kan.
  o131-MW Cimarron II Windpower Project in Gray County, Kan.
  o69-MW Laurel Hill Windpower Project  in Lycoming County, Pa.

Duke Energy also has three other windpower projects in Texas: Sweetwater in
Nolan County; Ocotillo in Howard County; and Notrees in Ector and Winkler
Counties. Since 2007, Duke Energy has invested more than $2.5 billion to grow
its commercial wind and solar business.
