NOTICE DATE: February 22, 2013
NOTICE TYPE: W-B021513-02 Update: Operations
SHORT DESCRIPTION: Issue with Day-Ahead Credit Exposure posting
INTENDED AUDIENCE: ERCOT Counter-Parties
DAY AFFECTED: February 14 - February 21, 2013
LONG DESCRIPTION: On February 14, 2013, ERCOT first published the Day-Ahead Market (DAM) Aggregate Credit Exposure report (EMIL ID NP4-411-CD) as a partial implementation of Nodal Protocol Revision Request
(NPRR) 407, Credit Monitoring Posting Requirements (formerly “Credit Monitoring Credit Parameters Posting Requirements”). ERCOT detected an issue with the calculation for certain entities, whereby the sum of the credit exposure for each individual transaction
type did not equal the total DAM credit exposure.
ERCOT released a fix late on February 21 and this issue has now been corrected.
