Revisions made in interconnect for 109-MW Pecos Solar project in Texas

American Electric Power Service Corp., on behalf of affiliate AEP Texas North Co. (TNC), on July 6 filed with the Federal Energy Regulatory Commission a fully executed First Amended and Restated ERCOT Standard Generation Interconnection Agreement dated June 14, 2016, between TNC and Duke Energy Renewables Solar LLC.

Duke’s 109-MW Pecos Solar Plant will be located in Pecos and Crane counties approximately seven miles southwest of McCamey, Texas. Once the facilities are completed and energized, the Point of Interconnection will be located at the dead-end structure inside TNC’s Rio Pecos Station that terminates Duke’s 138-kV transmission line from the Pecos Solar Substation.

The parties entered into this revised agreement for reasons that include:

  • Duke requesting to defer the written authorization to proceed with design and procurement from the date of execution of the original ERCOT Standard Generation Interconnection Agreement to 22 months from the execution date of the original agreement;
  • Duke requesting to defer the written authorization to commence construction from three months to 28 months from the execution date of the original agreement;
  • revising the scheduled commercial operation date from 18 months past the execution of the original agreement to 42 months;
  • revising the plant’s capacity from 108 MW to 109 MW;
  • revising the number of solar units and size from 128 units at 0.850 MW each to 54 units at 2.025 MW each; and
  • revising the type of inverters used from SMA model 900CP-US inverters to SMA Model SC2500-EV inverters.
