Duke files EWG notices for 310 MW of Los Vientos wind projects in Texas

Los Vientos Windpower IV LLC, which is an indirect subsidiary of Duke Energy (NYSE: DUK), on Oct. 13 filed with the Federal Energy Regulatory Commission a notice of self-certification as an exempt wholesale generator.

Los Vientos IV is currently engaged in the development and construction of a 200-MW (nameplate) wind facility located in Starr County, Texas. The facility will consist of an array of 100 Vestas V110 2.0 MW wind turbines. It will interconnect to Electric Transmission Texas LLC’s transmission system via a point of interconnection at a dead-end structure inside Los Vientos IV’s Jackie Howard substation in Starr County, which terminates an Electric Transmission Texas 345-kV line from its Del Sol station.

Los Vientos IV is party to a Power Purchase Agreement with the City of Austin’s Austin Energy municipal utility, dated as of Sept. 23, 2013. Under the agreement, Los Vientos IV will sell 100% of the net electric energy produced by the facility, as well as associated environmental attributes and ancillary services to Austin Energy. The agreement has a term of 25 years from the date of commercial operation.

Austin Energy had announced May 12 that it added two commercial wind plants to its fleet in late April, pushing the city-owned utility well past 1,000 MW of wind-powered electric capacity. Austin Energy began purchasing wind power in 1995 from the state’s first commercial wind plant. Since then, Austin Energy has added nine additional wind contracts in areas across Texas. The new projects are:

  • On April 22, the Jumbo Road wind farm began commercial operation. The Jumbo Road facility is located in the Texas Panhandle and is owned and operated by TX Jumbo Road Wind LLC, a wholly owned subsidiary of BHE Renewables. The project consists of 162 wind turbines with the capacity to generate approximately 300 MW. Austin Energy will purchase all of the power from the Jumbo Road wind farm under an 18-year agreement.
  • The Los Vientos III project, owned and operated by Los Vientos Windpower III LLC, a subsidiary of Duke Energy Renewables, began commercial operation on April 24. The project consists of 100 wind turbines and is located about 100 miles west of Brownsville near Rio Grande City in Starr County. The capacity of the Los Vientos III wind farm is 200 MW. Austin Energy will purchase all of the power under a 25-year agreement.

EWG notice filed for another Los Vientos project

Also on Oct. 13, Duke Energy’s Los Vientos Windpower V LLC filed with FERC its own notice of self-certification as an exempt wholesale generator. Los Vientos V is currently engaged in the development and construction of a 110 MW (nameplate) wind facility located in Starr County, Texas. This facility will consist of an array of 55 Vestas V110 2.0 MW wind turbines that will interconnect to Electric Transmission Texas LLC’s transmission system at a dead-end structure in its Liston substation.

Los Vientos V is party to three different power purchase agreements.

  • One agreement is with the City of Bryan, Texas, a home-rule municipal corporation which owns and operates Bryan Texas Utilities. This deal is dated as of Aug. 28, 2014. Los Vientos V will sell to Bryan 27.27% of the actual capacity of the facility, as well as associated environmental attributes and ancillary services. The agreement has a term of 25 years from the date of commercial operation.
  • Another agreement is with Greenville Electric Utility System, a municipally owned utility and a separate and distinct instrumentality of the City of Greenville, and is dated Aug. 28, 2014. Los Vientos V will sell to the Greenville 27.27% of the actual capacity of the facility, as well as associated environmental attributes and ancillary services. The deal is for 25 years from the date of commercial operation. 
  • The third agreement is with the City of Garland, Texas, a Texas municipal corporation, and is dated Aug. 28, 2014. Los Vientos V will sell to Garland 45.46% of the actual capacity of the facility, as well as associated environmental attributes and ancillary services. The agreement has a term of 25 years from the date of commercial operation.
