Time-of-Use (TOU) Price Factors Recalculated for Summer 1998

The Time-of-Use PX Energy Price Factors calculated by SCE during the summer of 1998 were incorrect.

SCE announced this finding at the February Rule 22 Committee meeting and at the April 16 ESP Seminar. The revised and corrected PX Energy Price Factors appear as links in the list below.

The files are in the standard Monthly Weighted Average Price Factor format established in December 1998. However, the contents of the new files only include the revised On-Peak and Mid-Peak price factors (the only factors that were originally incorrect).

The new files follow the "pnYYMMDD" naming convention, where "pn" stands for "Price New". The date in the file name identifies the START_DATE supported by the file.

The following references provide information used in calculating the PX price factor:
