Retail Sub-Committee Update
2
Objectives
• Update on PTB Synchronization Plan– Status on synchronizing the CR of record
• Provide Update from Previous RMS issues– Portal Performance and Changes– IDR / Non IDR Meter Usage Reports– 867-03 Forwarding Updates
• Information on Enhanced MP EDI Reporting Effort
3
PTB Synchronization Plan
• To address the current market issue with the rep of record getting out of synch between ERCOT, TDSP and CR systems.
• The transition to AREP process identified some of these, and the Move In and Move Out “safety net” processes, market gaps and various system issues have caused many more.
• The objectives of this project are to provide a plan to; – Identify the size of the problem – Provide root causes and options for correcting (if available)– Develop and implement a technical plan to synchronize databases
• The Non-PTB (Over 1 MW) ESI Ids are being addressed through another process
.
4
Market Synchronization Update
• RMS synchronization plan was approved at TAC unanimously
• Kick off Conference Call meeting took place 5/21
a) Minutes distributed 5/22
• Most TDSPs and CRs have identified at least one business and one technical contact to work with ERCOT
• All parties agreed to action plan:
a) Each MP will ensure internal/provider systems are synchronized
b) A test run will occur to ensure queries and file layout are correct
c) This test run begins on May 29th and will complete by June 7th
5
PTB Synchronization Plan - Next Steps
• Market continues to support plan with appropriate technical and business resources being assigned.
• Test files will be processed by ERCOT and finalize format and comparison programs verified.
• ERCOT will work with MPs to correct any file format issues.
• Pull together a detailed project plan to evaluate differences at a point in time and document steps required to correct
• Full data send/analysis will take place once test run is complete
• Report through RMS

Portal Performance Items
• Mux E Way fix from Seebeyond on week of 3/30– Saw a temporary 7 % improvement
• Moved Portal E Ways to New Hardware week of 4/13– Saw a temporary 10 % improvement
• Added components (threads) on 4/25– Showed some very promising improvements
• Additional Architecture change was made 5/21– Removed TCH component competing with batch transactions– Seeing a 30% improvement in errors– Also added “heartbeat” functionality to verify EAI every minute
• Looking at 2 additional improvements currently being tested– Moving Siebel queries directly to Oracle– Improvements in redundancy for find transactions
• Future options also being evaluated– Additional redundant paths for Portal transactions– Continue to analyze errors and respond

867-03 Forwarding
• ERCOT believes we are forwarding all 867s that have forwarding information provided
• ERCOT provides 867 forwarding information on the current MP reports to facilitate reconciliation
• ERCOT samples of turn around time are well within protocols
• Next Steps– Should point to point 867 continue?– If MPs believe ERCOT is not properly forwarding 867-03s, provide
Examples for ERCOT to check
