AEP files new interconnect for smaller Rocksprings Val Verde wind project in Texas

American Electric Power Service Corp., on behalf of affiliate AEP Texas Central, on Feb. 22 filed with the Federal Energy Regulatory Commission a fully executed First Amended and Restated ERCOT Standard Generation Interconnection Agreement dated Feb. 1 with wind project developer Rocksprings Val Verde Wind LLC.

The amended agreement provides for the electrical interconnection of a planned 149.34-MW wind facility. Rocksprings Val Verde’s Fermi Substation will be located in Val Verde County approximately 30 miles north of Del Rio, Texas. The temporary Point of Interconnection will be located at the jumper connection between the existing Hamilton Road-to-Sonora 138-kV transmission line and the power project developer’s 38-kV transmission line built to a point underneath the Hamilton Road-to-Sonora 138 kV transmission line. The permanent Point of Interconnection will be located at the dead-end structure inside AEP Texas Central’s Maxwell 138-kV station that terminates the developer’s 138-kV transmission line from the substation.

These facilities are scheduled to achieve commercial operation within fourteen months after applicable conditions have been satisfied.

The parties originally entered into an ERCOT interconnect deal as of Aug. 12, 2015. The parties agree to amend and restate the original agreement to revise the nominal plant capacity and the number of generating units.

This current version of the project involves a nominal 149.34-MW capacity comprised of 53 units at 2.3 MW each and 16 units at 1.715 MW each. These will be General Electric wind turbines.

The version of the project from last year’s SGIA had 180 MW of capacity composed of 90 GE turbines at 2 MW apiece.
