Response: 

Southwest had a 15-year term storage contract with SoCalGas that commenced in 1993 and terminated March 31, 2008.   The long-term storage contract provided Southwest 1.5 Bcf of inventory, 60 MMcfd of withdrawal rights and 12.5 Mmcfd of injection rights.  The following are the annual fixed costs (calendar year) of each component of the long-term storage service from 2004 through 2007.

Response to SCE-DR-1-1:  (Continued)

Inventory     $   330,682.50
Injection      $   145,608.80
Withdrawal $   715,826.70
Total           $1,192,118.00

The above annual costs were readily available and were extracted from Southwest's Gas Transaction System.  In order for Southwest to provide the annual fixed costs associated with the long-term storage services prior to 2004, Southwest would need to research and gather historical invoices from Archived files which may not be readily available.

Per Decision 07-12-019, SoCalGas set-aside to Southwest 1,602,023 Dth of inventory, 7,483 Dth/day of injection rights and 45,120 Dth/day of withdrawal rights.  The term for these storage services is April 1, 2008 through March 31, 2009.  The following are the rates associated with each component of the storage service, which equal the fully-scaled LRMC rates that the Combined Portfolio is charged for storage services.

Inventory     $ 0.3754/Dth 
Injection      $ 35.43/Dth
Withdrawal $ 20.35/Dth
