If I'm reading http://www.ercot.com/content/cdr/html/real_time_system_condi... right there is no power across the DC_L (Laredo VFT), DC_R (Railroad) and DC_S (Eagle Pass) HVDC ties.

for posterity:

  DC Tie Flows  
  DC_E (East)  -595  
  DC_L (Laredo VFT)  0  
  DC_N (North)  -218  
  DC_R (Railroad)  0  
  DC_S (Eagle Pass)  0
