Oil and gas properties profile change request. 1. Submitted to ERCOT 3/6/03 by Pioneer Natural Resources, Priority Power
Management, and Energy Data Source .

4. ERCOT is to evaluate and submit recommendation to PWG.
5. May test the new PUCT Rule 25516 for reimbursement.
6. ERCOT shall post the methodology request to the Market Information System (MIS) and respond to the request within sixty (60) days of the posted date of the request. This period does not include the time to analyze and render the complete assessment of the request.
7. “ERCOT withholds a decision on making a recommendation on whether to adopt or to deny adoption of the suggested profile change; instead ERCOT finds the request, as submitted, is incomplete and deficient. The requestors are invited to address the incompleteness and deficiencies listed below and re-submit the request for further review.”
8. Per 6/19 PWG meeting, a straw-man in development for changes to the profile change request process and to allow lagged dynamic samples.

3. ERCOT Schedule is pending, Project Manager assigned.
4. ERCOT and some Market Participants question priority going forward.
5. PRR Section 6 Language for DLC still needs to be written for a PRR.6. Memo, on Project 26359 on Competitive Metering, May 8, 2003, by Commissioner Perlman
suggests that wires companies need to develop a rate structure that provides strong incentives for demand responsiveness by charging different rates during high load periods.
7. PRR388 and PRR400 does not completely cover DLC issues.

IDR Requirement ReportLoad Profiling Guides, Section 9.2.3.3.1 Non-IDR to IDR (NIDR to IDR)
Per Protocols Section 18.6.1, "Interval Data Recorder (IDR) Installation and Use in Settlement," any ESI ID that exceeds 1000 kW or 1000 kVA in any two (2) billing months in the most recent twelve (12) month period or that receives service at 60 kV or above is required to have an interval data recorder (IDR) installed and utilized for settlement. ERCOT shall monitor the peak demand level of demand metered customers and post a monthly report to the Market Information System (MIS), with the appropriate Portal security rules, detailing which ESI IDs are required to have an IDR installed. The CR serving the ESI ID has thirty (30) days to verify the demand level and request that the TDSP install an IDR. If the CR does not agree that the IDR criteria have been met, the CR shall refer to Section 14.3, "General Dispute Resolution Guidelines," to address the issue.
The TDSP has until the second regularly scheduled meter read date after receipt of the CR’s request to install the IDR. The TDSP shall update the Load Profile ID in the ERCOT systems effective on the meter install date, via the appropriate Texas SET transactions.

Default Profiles1. PWG reviewed 7/30/03.
2. Requested ERCOT staff examine PWG suggestions if a new module can be added to the settlement software to allow ways of scaling the default profiles when both the IDR data is missing and/or a NIDR premise changes to IDR.
3. PWG and ERCOT staff to further discuss at the 8/19 PWG meeting.
