NOTICE TYPE: W-A070208-01
Operations
CLASSIFICATION: Public
SHORT DESCRIPTION: RPRS
did not solve within the allocated run-time on June 30, 2008 for the July 1
trade date.
INTENDED AUDIENCE: QSEs
DAY AFFECTED: July 1,
2008
LONG DESCRIPTION: On June
30th, while executing the Replacement Reserve market for July 1st,
ERCOT did not approve RPRS procurement. The RPRS market engine timed out before
solving. ERCOT diagnosed the problem to be a maximum execution time limit.
This limit exists to prevent the program from attempting to solve an
unsolvable case. RPRS was programmed to complete execution in 2000
seconds (33 1/3 minutes) and, on June 30th, did not solve within the
allocated time. The increased time required may have been related to a
change in scheduling requirements that went into effect July 1st. The
execution time limit has been increased.
CONTACT: If you have
any questions, please contact your ERCOT Account Manager. You may also call the
general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client
Services via e-mail at [log in to unmask].
