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

.

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

• 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
