Main Text:  As the California ISO (CAISO) indicated in a market notice issued on May 31, 2007, the CAISO was analyzing Generator Must Offer Waiver Denials (MOWD) that occurred during the period June 1, 2006 through February 28, 2007 for purposes of preparing weekly Significant Event / Repeat Waiver Denial Reports as contemplated in the Reliability Capacity Services Tariff (RCST) Settlement.  The CAISO has conducted a MOWD evaluation after every four separate days in which the CAISO issued a MOWD to a Must Offer Generator.  As part of its analysis, the CAISO has determined whether or not any Significant Events occurred during this period that might warrant RCST designations under the RCST Settlement.

 

The CAISO has published a summary report to its website at http://www.caiso.com/17c6/17c6a16019910.html that provides an analysis of the major events which occurred over the period June 1, 2006 February 28, 2007 and indicates whether any of those events would qualify as Significant Events warranting a RCST designation.

 

Over the next 1-3 weeks, the CAISO will begin publishing the weekly “Significant Event / Repeat Waiver Denial Reports” for the period which will describe in more detail the reasons for Must-Offer Generator commitment.  Over the next 3-5 weeks, the CAISO will begin publishing the Significant Event/Repeat Waiver Denial Reports for the period March 1, 2007 through the present.
