NY – Con Ed ESCO-Newsletter-Issue-2025-32 RAIS Sync List update
Category: New York
RAIS Sync List update
We have added two new fields to the Retail Access Information System (RAIS) Synchronization List:
- Last To Date – This is the last bill that is posted on the account
- Last Made Date – This is the date the Last To Date posted to our billing system
These additions aim to improve transparency around delayed billing for ESCOs. The File Layout has been updated accordingly. Please refer to the new columns highlighted below in red.
We are applying the same update to the Transportation Customer Information System (TCIS) Synchronization List. However, this update requires more manual effort. Once the changes are complete, we will send out a newsletter.
