XIII. System "Window" Procedures

PG&E has raised the issue of SoCalGas' operation of its receipt point "windows." SoCalGas' windowing procedure is an allocation methodology that establishes the amount of throughput capacity available at each of its interstate gas transmission receipt points on a daily basis for customers trying to ship gas through those receipt points for volumes to be received into the SoCalGas intrastate transmission system. Arguing that it has problems with SoCalGas' current windowing process, PG&E recommends that SoCalGas should modify its windowing procedure to include: (1) a fixed minimum window to be established at each receipt point on SoCalGas' system; (2) a fixed minimum window at Wheeler Ridge for PG&E in the amount of 440 MMcf/d; (3) the establishment of Hector Road as a normal receipt point; and (4) SoCalGas' development of a system of access to its transmission system based on firm and as available contract rights.

SoCalGas responds that the issues PG&E raises concerning SoCalGas' "windowing" procedures are addressed thoroughly in Gas Industry Restructuring and therefore should not be addressed in this BCAP.

In D.99-07-015, we addressed SoCalGas' windowing procedure and requested that the utility file an advice letter containing proposed windowing tariffs. In response, SoCalGas filed A.L. 2837, protested by PG&E, which is currently pending. Additionally, in I.99-07-003 the windowing procedure is being considered. The issue is not new. It was considered in D.99-07-015, is being considered in regard to A.L. 2837, and will be considered in I.99-07-003. There is no need to consider it here.
