Pisgah Area
? CAISO and SCE Proposed Projects / Upgrades
? Existing 230 kV Pisgah substation is expanded to 500 kV (part of the
Stirling project which is expected to be filed in 2010)
? Loop in the existing Eldorado-Lugo 500 kV line into Pisgah to form
Pisgah-Lugo No.l (part of the Stirling project and requires CPCN)
? Upgrade existing Lugo-Pisgah No.2 220 kV line to 500 kV to form Pisgah-
Lugo No.2 (part of the Stirling project and requires CPCN)
? Loop in the existing Lugo-Mohave 500 kV line into Pisgah 500 kV
Substation to form Pisgah-Lugo No.3, proposed by CAISO (not part of
the Stirling project and may require a CPCN)
? New 500 kV line from the upgraded 500 kV Pisgah substation to the
existing Rancho Vista 500 kV substation which is by Etiwanda (not part
of Stirling project and requires a CPCN)
? Transmission configuration can deliver 3500 MW of renewable energy (per
CAISO 2020 Renewable Transmission Conceptual Report)
? 2500 MW solar

Pisgah Area (continued)
? Pisgah-Lugo
transmission line
? Project replaces the existing 220 kV Pisgah-Lugo line with a
500 kV line.
? Stirling filed an AFC for the Solar One generation with the
CEC Dec 2, 2008 and CEC deemed the application data
adequate May 6, 2009.
? CPUC had discussions with Stirling, CEC, BLM, and SCE in
2009 to discuss possibly expediting this project using the CEC
AFC process. It is not possible to use CEC/BLM environmental
document since SCE does not have all applicable upgrade
details to meet CEC required deadlines.
? SCE is expected to file an application for the Pisgah to Lugo
transmission line upgrade with the CPUC in 2010
? SCE may possibly need to file 1 to 3 CPCNs in this
renewable area depending on the timing of these upgrades

CAI SO and/or SCE Propose d Transmission Upgrades
Redacted
formerly Midpoint, 500 kV switchyard - This new switchyard
with completed environmental review (Devers - Palo
Verde #2) would need
CPUC decision through a Petition To Modify (PTM). PTM decision anticipated to
pe on the Nove mber 20, 2009 Commission meeting. _______
Redacted
500/230 kV substation - The Redacted
Switchyard will be
modified to a substation configuration utilizing 500/230 kV transformation (It is
not part of DPV2) I am not sure that this is correct statement?? SCE - Isn't this a
o^,! 1 -rution Sub and switchyard at same location???
Red Bluff 500/230 kV substation - New Substation proposed at Desert Center
(Same as Desert Center 500 kV substation proposed in RETI Phase 2A). May
require PTC or CPCN but possibly no environmental review by the CPUC. CPUC is
working on MOU with BLM to use a NEPA document that is CEQA compliant so it
can be used for a later PTC or CPCN filing
Colorado R iver-Red Bluff-Devers #2 500 KV line - This is the DPV2 line from
Redacted
looped into Red Bluff Substation (This line was
permitted per the DPV2 CPCN)
Devers - Valley 2nd 500 kV - Part of DPV2 project going from Devers to Valley
substation. Does not require a separate CPCN since it is part of DPV2 Project
Colorado River-Red Bluff-Devers #1 500 KV line - Existing DPV1 500 kV line
looped into new Colorado River and Red Bluff Substations. This may require a
PTC or CPCN or may be exempt if it there are service drops into the substations.
Red Bluff-Valley 500 kV line - A third 500 kV line in addition to DPV2 from Red
Bluff (Desert Center) substation to Valley substation forming a new Red Bluff -
Valley 500 kV line. Most likely requires a CPCN.
