The transition to Daylight Savings Time is rapidly approaching. In preparation ISO Market Operations has provided the following Scheduling Procedure to help assure a smooth transition. The Scheduling Procedure is the same one used in 2001. CAISO Scheduling Procedure for Daylight Savings Time Transition The following is a brief explanation of how SC's should prepare schedules for submission to the CAISO Scheduling Infrastructure (SI) system for the upcoming conversion to Daylight Savings Time commencing on 4/7/02. When submitting preferred or revised preferred schedules for Trade Date 4/7/02, which is considered a "Short" day, SC's should schedule all 24 hours of information with the data for HE03 being zero. The ISO's System Applications (SA) do not read or write data from/to the SI database for the "Short" day's HE03. Therefore, no data will be sent to settlements for this hour. Consequently, settlements will have only 23 records for this "Short" day, Trade Date 4/7/02. If you have additional Scheduling questions for this trade date, please contact Alek Kandybenko, ISO Market Operations, @ (916)351-2213. > CRCommunications.1108 > Client Relations Communications > >
