  1. Why are we here? FPLE is seriously concerned that the upgrades being constructed in the McCamey area are not adequate.

  2. Concerns • McCamey Area Plan, as it is currently being implemented, will not meet the existing requirements of 755 MW, much less the 900 MW announced by ERCOT • Findings need to be verified • Generation patterns may result in lower limits • Additional mitigation alternative considerations • Timing • Implementation by ERCOT

  3. Hub and Spoke Implementation

  4. Assumptions • Rio Pecos capacitors in-service • RAPs in the 69 kV system • Big Lake – McCamey 138 @ 149/170/170 • Operations case at 52000 MW load (80%), McCamey area load 144 MW • Outages required for upgrade construction not modeled

  5. AssumptionsRAPs • Shef-Iran 69 kV • Atlt-Humt 69 kV • Odnth-Pegtp 69 kV • Illn-Oznr 69 kV • FtL-Iln 69 kV

  6. Findingsw/o Capacitors Included; RAPs Used

  7. FindingsAll Capacitors Included; RAPs Used

  8. Why is there a difference? • Dispatch outside McCamey was not taken into account when the plan was originally developed • If generating units in the Odessa area are dispatched, a portion of the generation flows through McCamey

  9. Potential Mitigation Alternatives • Accelerate Ft. Lancaster to Friend Ranch 138 kV by an additional 6 months • Install Breakers at North McCamey • Add Tension Monitors in Crucial lines • Implement SPS • Start building 345 kV line • Other

  10. Breaker Addition at McCamey

  11. Maximizing Line Capacity • Limiting lines and tension monitors • Rio Pecos to Crane 138 kV • North McCamey to Big Lake 138 kV • SPS until the 345 kV is completed
