Agenda Item 3x: Load Research Project Update and Timeline

Diana discussed the LRS timeline presentation (posted at

When asked whether they had any issues with LRS data being collected through December 2009, none of the TDSPs voiced concern, other than Lloyd Young stating that it would not be a problem as long as ERCOT uses the data.

Kyle said that CenterPoint would not change to AMS on LRS sites until after December 2009.

Ernie mentioned that due to the advent of advanced meters it may be prudent to consider whether to proceed with sampling after this round. Also, Bob Laningham would like for the group to discuss sometime in the future the role of load profiles in an AMS environment.

Ernie will include the LRS timeline in the presentation to COPS.

Kyle sent the 100 or so ESI IDs referenced in last month’s conference call to ERCOT, and said that ERCOT did a good analysis on them.

Ernie asked that ERCOT update the open items list to say that we’re waiting for AMS implementation schedules from two TDSPs.

Kyle asked whether there would be an issue in sending in 814_20 transactions related to AMS during the time that annual validation transactions would be sent.

Ernie asked whether there is still a limit of sending 50k transactions per day, and whether 814_20 changes related to AMS would have to be coordinated with the Load Profiling staff or someone else at ERCOT. Calvin spoke a bit on the 50k issue and Diana said it might be a different group at ERCOT that would coordinate this and that she would check on it.

Kyle said that CNP would probably be submitting approximately one million 814_20 transactions.

Bob asked whether there would possible be a delay in annual validation because of changes related to AMS at ERCOT.

Calvin and Diana concluded that the above concerns with the magnitude of 814_20 transactions should not pose significant problems.

Ernie asked whether a 150-day notice is called for given the new valid Profile IDs that may be approved by the ERCOT Board in March. Adrian said that off the top of his head the 150-day notice is not mandated because there are actually no new or modified models being introduced. After a brief discussion Adrian said that ERCOT would send out a Market Notice on the new valid Profile IDs as a courtesy, if LPGRR032 is approved by the Board.

ACTION ITEM: ERCOT to send out a Market Notice if LPGRR032 is approved by the Board.

Agenda Item 4: Review Target Timeline for 2009 PWG Goals

ACTION ITEM: Diana is to update the PWG 2009 goals document and send it to Ernie so that he can forward it to COPS.

When asked about an implementation date for the advanced metering interim solution, Calvin checked and found out that ERCOT will make an announcement at the MARS meeting scheduled for March 9.

Next PWG Meeting

The next PWG meeting is scheduled for March 25, 2009, and is likely to be a conference call, but Ernie will send out a notice once the details are finalized.
