SCE Pardee to Santa Clara 230 kV

Evidence chain

1. 1

   Policy, planning or funding trigger

   SCE's SB1006 advanced conductors and grid enhancing technologies study describes roughly 40 miles of HTLS reconductoring with a 2,180 A emergency rating target, including replacement of four 1,200 A disconnects at Santa Clara with 3,000 A equipment.
2. 2

   Why this project is exposed

   Later stakeholder materials show significant cost escalation and cost transparency scrutiny, which puts the proposed approach and its structural modification scope in play.
3. 3

   Relevant TS capability

   Conductor achieving the required emergency rating with reduced structural modification, supported by line specific installed cost analysis.
4. 4

   Is specification still influenceable?

   Yes at the concept stage. There is no approved project and no procurement, so the evaluation basis is still being formed.
5. 5

   Recommended commercial action

   Prepare a line specific installed cost and structure modification comparison and hold it ready for the next scope discussion.
6. 6

   Likely buyer

   SCE transmission planning and engineering.
7. 7

   Key uncertainty

   Whether the concept advances at all, and under what scope and cost assumptions, is unresolved.
