MEETING OPEN
The banana (and blueberry) bread provided by Diana was excellent. Ernie read the
antitrust admonition, reviewed the agenda for the meeting and updated the group on the
COPS meeting. COPS applauded the PWG for the hard work on the profile updates.
The notes for the 11/14/06 meeting were approved. The approved notes will be posted
to the ERCOT website.
ANNUAL VALIDATION UPDATE
Ernie reviewed the Annual Validation 2006 Update. The consensus was there needs to
be additional language in the LPGRR defining a cutoff. Lloyd suggested a PWG vote
would be sufficient. Carl explained the Annual Validation is subject to SAS 70 audit so a
vote would probably not be sufficient.
Diana mentioned that a CR is automatically creating MarkeTrak issues through the API.
The CR is working to resolve it.
Action Item: Diana will draft LPGRR language to define the end of Annual
Validation.
LRS UPDATE
Bill presented the LRS Progress Report and bar chart. Bill explained the bar chart now
includes the percent of data in the ALDB and the CLDB so a more accurate percentage

of available data is reflected. In the past there were 2 cuts that were not included in the
percent of data received.
Backcast Profile File Name and Format Discussion
Ernie reviewed the presentation that was presented to COPS. DEWG consensus was to
post forecasted load profiles generated only from new models from May 15th onward.
Carl explained the three posted documents are the best information ERCOT has at this
time on how Option 3M will be implemented. Option 3M will allocate residual energy (for
kWh balancing) to only the new profile periods going forward. Carl will remove the
document named “LP Transition Option 3 Problem-modified-a” to avoid confusion.
Profile Refresh Frequency Discussion
Ernie suggested including the profile refresh as part of the PWG long range goals or
include in a report to COPS in the next few months along with the round 2 sample
schedule. Every 2 years would be aggressive. Other unpredictable components are
new profiles (i.e. Oil/Gas), advanced metering and IDR thresholds.
TDSP Feedback on DST Issues
Three TDSP’s reported they will be ready for the new spring DST change on
March 11, 2007.
Action Item: TNMP will follow-up and report to ERCOT.
PWG Leadership Nominations
PWG 2007 leadership nominations were: Ernie Podraza, Brad Boles. Nominations by
email (to whom???) will be accepted up to the election scheduled for the next PWG
meeting on January 30, 2007.
Review and Poll for Final Consensus on LPGRR017 (BUSOGFLT)
The comment period for LPGRR017 has ended. The PWG recommends approval of
LPGRR017 regarding the Oil/Gas profile (BUSOGFLT) per the modifications made to
the Decision Tree during the PWG meeting on December 20, 2006.
The PWG reached consensus on changing the language to the Decision Tree, Appendix
D, Oil & Gas tab. This change more specifically defines the process where a CR may
submit requests to change the Profile ID assignment to ERCOT with appropriate
documentation.
PWG Meeting Notes – 12/20/06
Action Item: ERCOT will draft a transition plan for presentation at the January
PWG meeting. The transition plan will include an estimate of the timeline and
implementation day and forecast and backcast issues. Market participants should
send implementation issues and costs to ERCOT to be included in the transition
plan.
Review LPGRR for Default Profile ID Assignment by Weather Zone
PWG completed the draft of LPGRRxxx – Review Default Profile ID Assignment by
Weather Zone. Ernie will fill-in the sponsor area, include the Decision Tree input from
Adrian and file with Market Rules. The LPGRR will follow the normal market approval
timeline.
Review 2007 PWG Goals
Ernie presented the list of 2007 goals that he had compiled. The comment was the list
seems more like a “task list”.
Action Item: PWG members are asked to review the goals for prioritization next
month.
Review Action Items and Open/Close Items lists.
Ernie reviewed the Action Items and Open/Close Items lists.
Action Item: Carl will post the updated lists to the web site.
