SHORT DESCRIPTION: Total Potential Exposure (TPE) calculations affected by ERCOT system outages
INTENDED AUDIENCE: ERCOT Counter-Parties
DAY AFFECTED: March 13, 2014
LONG DESCRIPTION: Per ERCOT Protocol Section 16.11.4.6(c), “If all or part of a Counter-Party’s ACLC and/or ACLD cannot be computed due to an ERCOT computer system failure, then ERCOT shall estimate ACLC and/or ACLD for that
Counter-Party and provide the information used to determine such estimates to that Counter-Party. If all or part of ACLC and/or ACLD cannot be estimated with current data, then the most recently available values shall be used to determine the Counter-Party’s
ACLC and/or ACLD.”
The ERCOT system outages commencing on March 11, 2014 have impacted the ability to calculate Counter-Party Total Potential Exposure (TPE) and Available Credit Limit
(ACL). Counter-Parties should be aware that Real-Time Market estimated values for Operating Day March 12, 2014 are not included in the following components of the TPE and ACL calculations:
·
Real-Time Liability Forward (RTLF)
·
Real-Time Liability Computed Not Settled (RTLCNS)
The most recently available values used in RTLF and RTLCNS for Operating Dates prior to March 12, 2014, including the Operating Day March 11, 2014 which was excluded from yesterday’s calculation, are utilized in today’s calculations.
ERCOT will send a follow-up Market Notice when these credit calculation inputs are restored.
