SHORT DESCRIPTION: Notice of newly identified issues with the Short-Term System Adequacy Report postings
INTENDED AUDIENCE: ERCOT Market Participants
DAYS AFFECTED: June 18, 2021 - current
LONG DESCRIPTION: On June 25, 2021, additional, separate issues were identified with the Short-Term System Adequacy Report (EMIL ID - NP3-763-CD, Report ID 12315). These newly identified issues are a function of changes that were made during the 2021-R3 release on May 27, 2021 and impact the following columns:
Specifically, for the AvailCapGen and AvailCapReserve columns, the hours beyond DRUC study range are missing capacity from Split Generation Resources, and over-counting the reduction in capacity of Intermittent Renewable Resources due to Outages.
This issue is different from the ones that were previously identified and resolved on June 18, 2021. ERCOT is currently working on the fix for this new issue and does not have a timeline for resolution. A follow-up Market Notice will be provided once it is resolved.
