CAISO Notice - Big Creek - Fresno Interconnection

< Market Participants:
<
< The California ISO is initiating a study to determine the feasibility of
< interconnecting SCE's Big Creek transmission system with PG&E's Fresno
< area transmission system. This study is being initiated to determine
< whether some form of interconnection between these two systems is
< beneficial to the overall system. Some of the potential benefits that may
< be realized by this interconnection are:
<
< (1) Expansion of the pumping window available for the Helms Project,
< (2) Reduction in RAS tripping for the generation and pump modes for the
< Helms Pumped Storage Project,
< (3) Improved spring and summer stability performance in the Big Creek
< system (and a subsequent reduction in RAS),
< (4) Improved reliability for the Rector, Vestal, and Springville load
< areas following double circuit line outages,
< (5) Additional transmission capacity for potential new generation in the
< area (Pastoria expansion and others) without major transmission
< construction, and
< (6) Incremental improvement to Path 15 transfer capability.
<
< A stakeholder group is being formed to provide input into the studies. In
< addition, a draft Study Plan has been posted on the ISO's web site for
< your review and comment
< ("http://www.caiso.com/docs/2001/06/14/200106141553509859.html"). Due to
< the expedited nature of this study, please provide your interest in
< participating on the study group and/or comments on the study plan to
< Peter Mackin (pmackin@caiso.com) by June 26, 2001.
<
< An announcement regarding the first stakeholder meeting for this study
< will be sent out shortly.
