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.

– Credit Limit Error• ERCOT continues to manually pre-populate the Credit data (historical prices, credit

limits, and other supporting data)

• As this is a manual process, there have been some issues with specific MP’s


Texas Nodal

Updates / Questions / Reminders

• Three Part Offers – Adjustment Period– If there are problems preventing TPO submissions prior to market

close, please submit TPO during adjustment period– This will minimize impact to LMP’s

• Reminder: QSE’s Performing ICCP Maintenance:– ERCOT is closely monitoring ICCP / Telemetered Data– If you have a planned maintenance period:

• Send a notification to [email protected]• Include the following information

– Date/time of maintenance– Expected duration

– This will prevent ERCOT from contacting MP’s when issues are found

LFC 6.3 pre-Test (REMINDER)

• QSE’s will submit a “deconstructed” zonal, portfolio-level offer as a resource specific, nodal TPO

• QSE TPO’s will be submitted into the RT market in the adjustment period– Please ensure:

• Appropriate staff are available to support submissions• ICCP data is of good quality• This is imperative to ensure a meaningful exercise on these dates
