CAISO Notice - Non-Operational Generation Report Change) (Subject: CAISO Notice - Non-Operational Generation Report Change) ISO Market Participants: Recently, some market participants have indicated that there is some confusion regarding the ISO's Non-Operational Generation Report, published once daily on the California ISO Web site. This report includes any outage to any unit at any time of the day. However, many of the reported outages occur off-peak while consumer demand is low. Generation that is fully available for peak periods can be shown as unavailable, even if it was unavailable for only part of the day.  To avoid this confusion and to provide more up-to-the-minute generator outage information as appropriate, the California ISO will now report Non-Operational Units on its web site based on a "snapshot" of conditions, rather than including all outages which may have occurred at any time during the day. Because system conditions may change throughout the day, we will update this report throughout the day. Beginning today, the ISO will publish the Non-Operational Generation Report four times daily at approximately 7:15 AM, 11:15 AM, 3:15 PM, and 7:15 PM at http://www.caiso.com/docs/2001/01/25/2001012508442613704.html. The first report will be later today. This snapshot report will state the time when the "snapshot" was taken.  Please keep in mind that this information is a snapshot of conditions at the time of the report and may change at any time. Also note that there may be multiple outages for any given unit on these snapshot reports. Without releasing confidential information, the ISO will indicate whether the outages are Planned or Unplanned. If there are multiple outages, there may be more than one such designation (one for each outage of record). We hope that this additional information will provide a more accurate picture of generator outages through the day. If you have any questions about this report, you may send them to Greg Van Pelt, Manager of Outage Coordination, at   gvanpelt@caiso.com.   CRCommunications
