Member testing for the SPP Transmission Settlement Timeline project began March 10th in the MTE environment. Included in this project are business process changes for Transmission Settlements which will result in changes to member data submission due dates and settlement posting dates for a given invoice month. Specifically, as stated by SPP, this is a "process change for transmission settlements to shift the timeline for daily settlement postings (PTP) in a given invoicing month to include the previous month's 24th day through the current month's 23rd day. This change will allow for more timely closing of the month end processes and postings."
Additionally, it will include enhancements to the TC Transmission Data Submissions. The MIPO may be accessed in the project folder and includes full details on these changes and the member testing plan.
