Stakeholder Meeting, April 10th, 2008 – LCR 2009

Changes since last Stakeholder meeting

Big Creek/Ventura:

Change the Antelope-Pardee sub-area need into second worst for BC/Ventura. Update QF units in Ventura. ATP (Antelope Transmission Project) Segments 1, 2 and 3 modeled. (Includes the opening of the existing Antelope-Vincent and Antelope- Mesa 230 kV lines)

LA Basin:

New sub-area El Nido Change Barre LCR in order to correctly account for the NQC available.

Stakeholder Meeting, April 10th, 2008 – LCR 2009

Changes since the 2008 LCR study

Total Big Creek/Ventura LCR has decreased

  • Load forecast is up by 26 MW
  • Detailed sub-area analysis has been presented
  • One new peaker modeled in the area
  • New project Antelope Transmission Project (New Segments 1, 2

and 3 plus the opening of the existing Antelope-Vincent and Antelope-Mesa 230 kV lines) has reduced the LCR

  • Overall the LCR has decreased by 480 MW

Stakeholder Meeting, April 10th, 2008 – LCR 2009

Changes since the 2008 LCR study

Total LA Basin LCR has slightly increased

  • Load forecast is up by 188 MW
  • New sub-area analysis El Nido presented
  • Two new peakers modeled in the area
  • New project Rancho Vista 500 kV Substation
  • Voltage collapse in the Barre area (a non-linear problem) has

increased substantially (about 1000 MW) for a rather small change in load and as a result resources in that sub-area need to be on-line when the LA Basin calculation is done. They displace some resources that would otherwise be much more effective to the

  • verall problem the South of Lugo constraint
  • Overall the LCR has increased by 95 MW
