On Friday, August 8, 2008, the following nonpublic transmission information was improperly disclosed to employees of SCE's internal marketing group, Energy Supply & Management.







4/23/2008
Last night [April 22, 2008] at approximately 4:38 PM MST, the 500/345kV bank in the Four Corners 500kV Switchyard experienced a failure of the transformer banks tertiary winding connections. The cause has not been determined at this time. Crews are currently disconnecting the three single phase transformers that form this transformer bank. There is one single phase spare transformer available for service. Oil samples are being collected for analysis. The transformers will be Dobled and SFRA tested sometime this evening.

If no more than one transformer is damaged, the transformer connections will be reinstalled and the bank will be returned to service. This disconnecting, testing, reconnecting, and return to service could be completed within three to five days, depending on conditions found during the inspections and testing.

If more than one transformer is damaged, the Moenkopi Line will not be in service until Unit 5 is returned to service, on or about May 28th. The Moenkopi line is capable of carrying all of the 755 MW output of Unit 5.

On Monday, April 7, 2008, the following nonpublic transmission information was improperly disclosed to an employee of SCE's internal marketing group, Energy Supply & Management. 

At the Scoping Meeting for the [redacted*] Phase 1 (TOT [redacted*]) and Phase 2 (TOT[redacted*]) [redacted*] determined that it would prefer to interconnect its Phase 1 Project to the Cottonwood-Savage 115 kV line.  As a result, [redacted*] has elected to withdraw its TOT Application for interconnection with CAISO (TOT [redacted*]) and resubmit its WDAT Application for the same project (WDT [redacted*]) with SCE. 

Please continue to use the existing Application Phase Work Order Number [redacted*] for WDT [redacted*].  If you have already incurred costs associated with TOT [redacted*], please apply these charges to the WDT [redacted*] WO Number.

* The redacted information contains confidential customer related information.

On Friday, November 16, 2007, the following non-public transmission information was improperly disclosed to employees of SCE's internal marketing group, Energy Supply & Management.

There is coordination between the Alberhill 500/115 kV project and the Lake Elsinore Advanced Storage (LEAPS) project.  The location of LEAPS’s Lee Lake substation was of concern because of the size of the proposed parcel by LEAPS.  The interconnection of LEAPS into Alberhill 500/115 kV project would consist of the addition of one position to the Alberhill switch rack.

The system needs associated with Nevada Hydro’s 500 kV transmission line were not studied. 

SCE’s Interconnection System Impact Study for LEAPS evaluated the following scenarios: Telega – Escondido/ Valley – Serrano (TE/VS) transmission line only (natural flow); 500 MW into SCE’s System; 500 MW into SDG&E’s system; 600 MW of load into SCE’s system; and 600 MW of load into SDG&E’s system

The system reliability and need for Nevada Hydro was not studied.
SCE’s Transmission and Interconnection Planning group has proceeded with its annual Expansion Plan study with out the TE/VS and/or LEAPS project and has taken the necessary steps to assure reliable service to the Lake Elsinore / San Jacinto region with its proposed Alberhill 500/115 kV project.  Method of service for the Alberhill 500/115 kV substation does not consider the TE/VS and/or LEAPS project.        

The Alberhill 500/115 kV project details:
- Up to 7-500 kV positions
- 4 -560 MVA 500/115 kV Transformer banks
- Up to 9 115 kV positions

Proposed to pick-up approximately 288 MW.


10/16/2007
On Tuesday, October 16, 2007, the following non-public transmission information was improperly disclosed to several employees of SCE's internal marketing group, Energy Supply & Management.

Nevada Hydro submitted an interconnection application with the California ISO to interconnect the 500 MW Lake Elsinore Advance Pump Storage ("LEAPS") project to SCE's Valley-Serrano 500 kV line and the San Diego Gas & Electric Company near Camp Pendleton.

A new interconnection substation is needed so that the LEAPS project can interconnect to SCE's electrical system, whereby the Valley-Serrano 500 kV line will be looped into the new substation. Also, several facility upgrades on SCE's system are required to accommodate the LEAPS project. The substation and upgrades must be included in the Nevada Hydro Environmental Impact Report (EIR). The new substation will basically be SCE's proposed Alberhill substation and may be relocated to the proposed Nevada Hydro 500 kV substation site.
