Lower Rio Grande Valley 345 kV Project
  • AEPSC Proposal
  • Construct a new 148 mile, 345kV transmission line from Laredo Lobo to Rio Bravo to Del Sol, a new 345kV switching station on the west side of the LRGV, utilizing 2-954 ACSR conductor on double-circuit capable structures, and a 24 ohm 3600 amp series capacitor on the Lobo 345 kV circuit
  • Construct a new 15 mile, 345kV transmission line from Del Sol to North Edinburg utilizing 2-954 ACSR conductor on double-circuit capable structures
  • Construct a new 15 mile, 345kV transmission line from Del Sol to Frontera utilizing 2-954 ACSR conductor on double-circuit capable structures
  • Estimated to cost approximately $380 million

study models criteria
Study models & Criteria
  • 2016 Summer Peak base case based on the latest (April 28, 2010) 2011 SSWG Data set B
  • 2020 Summer Peak base case based on the DOE 2020 Long-term study
  • Two wind farms with recent signed generator interconnections added to the base case and dispatched @ 10% capacity:
      • Los Vientos 400 MW Wind in Cameron County
      • Magic Valley 200 MW Wind in Willacy County
  • Silas Ray unit 5 turned off
  • Contingencies:
    • the loss of a transmission line, with the largest LRGV generation station out of service. (N-1 + G-1) for reliability criteria
    • the loss of a transmission line, with the prior outage (maintenance outage) of a transmission line (N-1-1) will be studied to determine the transfer capability but not used as a reliability criteria

other options and considerations
Other Options and Considerations
  • Evaluate the optimal location for the PST (for option 2 and 3)
  • Study PST options for the existing 345 kV line in the Valley
  • HVDC line from Pawnee
  • Obtain cost estimates for the different options and determine the feasibility of construction to meet the projected load growth
  • Evaluate the different options to assess the impact on the local area constraints/mitigation
