Description Of Issue
Business Practice Manual (BPM) 202 Participant Sharing Calculation Inputs describes the Multi-Day (MD) files necessary to run the Operations Program Sharing Calculation, which includes at least seven Operating Days’ worth of forecast data, and Operating Day (OD) files used to post updated Sharing Calculation results, hour by hour, for the Operating Day.
BPM 202 currently states that the OD file “is mainly used for informational purposes in the Operations Program.” While this statement is accurate, OD files are also utilized during the Preschedule Day Sharing Calculation process when both MD and OD files are available for the same operating hour. This functionality was implemented at the request of Participants to ensure the Sharing Calculations incorporate the most current forecast information that is available within the OD files.
Accordingly, BPM 202 should be updated to clarify the purpose and use of both MD and OD files, as well as provide greater transparency regarding the logic that the Operations Client applies when processing these files. These revisions will better align the BPM language with current operational practices and system functionality.
Proposed Solution
BPM 202 Participant Sharing Calculation Inputs – Language in Section 7.2 Operating Day File has been amended to bring clarity and transparency to OD file specifications as well as reflect the OD file prioritization over MD files in the Sharing Calculation when both files are available.

7.2. Operating Day File
The data requested in the Operating Day (OD) files (OD files) is necessary to run the Operations Program Sharing Calculation, which is the mechanism to determine whether a Participant is surplus or deficit on any given hour of the Operating Day.mainly used for informational purposes in the Operations Program. As the binding obligations are set on the Preschedule Day under the , input data submitted in the OD files is additionally used to post updated Sharing Calculation results, hour by hour, for the Operating Day. These updated Sharing Calculation results help inform a Participant about its position relative to the Sharing Calculation result posted on the Preschedule Day.
For operating hours in which MD and OD files are available, the Sharing Calculation prioritizes the use of OD files for hours containing concurrent data.
OD files include at least 24 (or 23 for the spring transition to daylight savings time) operating hours’ worth of forecast data and are to be submitted every hour throughout the Binding Season.
Per , Participants are required to submit an Operating Day file no later than one hundred and twenty (120) minutes prior to the start of any given operating hour.
