SHORT DESCRIPTION:  Delayed and missing postings for Resource AS Supply Insufficiency at 1430 Report

INTENDED AUDIENCE:  ERCOT Market Participants

DAYS AFFECTED:  December 1 – 14, 2010

LONG DESCRIPTION: The Resource AS Supply Insufficiency at 1430 Report has incurred posting delays and some missing postings for December 1 – 14, 2010.

The following posting days were made available on Monday, December 13, 2010. The reports were posted late due to extensive data validations being performed.

• Thursday, December 2
• Saturday, December 4
• Sunday, December 5
• Tuesday, December 7
• Wednesday, December 8
• Thursday, December 9

The following posting days were not made available and will not be made available. This is due to the Day Ahead Market (DAM) completing later than scheduled which did not give Market Participants (MPs) time to update their Current Operating Plans (COPs) based on DAM awards before the report was run (although MPs did have the required time of at least one hour to update their COPs prior to the Day-Ahead Reliability Unit Commitment, which was delayed). 

• Wednesday, December 1
• Friday, December 3
• Monday, December 6

The following posting days were not made available and will not be made available due to system issues.

• Friday, December 10
• Saturday, December 11
