Update on Adjacent Circuit Criteria and Coordination Efforts - RS Activities Report (Jan 2012)

The report outlines developments from the RS Update Drafting Team, finalized on January 27, 2012, regarding the criteria for adjacent circuits. Key points include the exemption for internal systems, minimum circuit separation requirements, criteria applicability involving 300 kV circuits, and the new approvals by PCC and the Board for implementation by April 2012. Additionally, it addresses coordination efforts with FAC 10/11 and efforts to respond to TSS queries regarding WECC Standard WRS1.2. Comments on the mapping of TPL-001-2 to WECC criteria are due by February 3.

  1. Marv Landauer Report to TSS on RS Activities January 25-27, 2012 Salt Lake City

  2. RS Update Drafting Team Finalized Adjacent Circuit Criteria (WRS1.1) at September 7 meeting: • Criteria does not apply to internal systems • 3 mile total exemption for station entrances, river crossings, etc. • Minimum separation of 250 feet for Adjacent Circuits • Only applicable if both circuits are above 300 KV • Only applies to adjacent circuits In previous proposal, a lower voltage intermediate circuit would not impact adjacency if outer circuits were within 250 feet (not raising the bar) - new • Approved by PCC in October • Approved by Board with April 2012 implementation • Coordination needed between new criteria and FAC10/11 White paper being prepared and possible revisions to FAC 10/11

  3. RS Update • RS preparing response to TSS request on clarification of WECC Standard WRS1.2 • PCUR underway for Hassayampa-Jojoba/Kyrene and Hassayampa-Pinal West double line outage.

  4. RS Update • Developing SAR to map WECC Criteria with TPL-001-2 • WECC criteria Table W-1 • Also mappingTable 1 between old and new TPL standards • Comments by February 3 to Catherine O’Brien
