  2. Antitrust Admonition ANTITRUST ADMONITION ERCOT strictly prohibits Market Participants and their employees who are participating in ERCOT activities from using their participation in ERCOT activities as a forum for engaging in practices or communications that violate the antitrust laws. The ERCOT Board has approved guidelines for members of ERCOT Committees, Subcommittees and Working Groups to be reviewed and followed by each Market Participant attending ERCOT meetings. If you have not received a copy of these Guidelines, copies are available at the Client Relations desk. Please remember your ongoing obligation to comply with all applicable laws, including the antitrust laws. DISCLAIMER All presentations and materials submitted by Market Participants or any other Entity to ERCOT staff for this meeting are received and posted with the acknowledgement that the information will be considered public in accordance with the ERCOT Websites Content Management Operating Procedure. http://nodal.ercot.com 2

  6. Special Topics Phase 2 Validation reports and process • Phase 2 validation re-evaluates all submitted transactions at 7 am in the day-ahead with updated information, such as AS Obligation, CRR ownership, credit limits, FIP/FOP for TPO caps, etc. • If there is a validation error, ERCOT will cancel the transaction • ERCOT sends a notice that a Phase 2 report is available for a particular transaction type, and notification containing the cancellation for the transaction. • You can query for the Phase 2 report via web services or on the Reports page of the Market Manager in order to view the reason for the cancellation. • If applicable, correct and resubmit prior to 10 am • Note that submissions are locked out during the Phase 2 process, which starts around 7 am and is currently taking about 5-10 minutes to complete. • Error message says that ‘submissions are not allowed during Phase 2 validation’ http://nodal.ercot.com 6

  11. FAQ Q: Can I self-commit my resource a partial day and submit startup costs for other hours? A: No. For example, if you attempt to self-commit hours 7-22, but submit startup/min energy offers for hours 1-6, 23-24, the offer is accepted structured this way, but hours 7-22 are not considered self-committed by the DAM and the clearing behavior will reflect a non-self-committed offer. Meaning, if there is no overlap with the LSL/HSL in the COP in the energy offer curve, that makes the energy offer curve invalid for use in the DAM. If there is an online AS Offer for the same resource, the QSE can be awarded energy at LSL in conjunction with the AS Offer. Note that this can cause a QSE to be awarded above the submitted energy offer curve. Q: Can I self-commit my share of a JOU if the other owners submit startup costs? A: No. Similar to the answer above, the energy offer curve will be accepted, but will be invalid for award by DAM if there is no overlap with the HSL/LSL in the COP. If the offer is invalid, the physical resource cannot be awarded. In this scenario, all owners have to self-commit or all owners have to submit full TPOs to be awarded. http://nodal.ercot.com 11
