7
Same CR Move-in
• Objective– Reduce volume of Move-in transactions at ERCOT
– Reduce Move-in error rate Market-wide
• Completed– Identified various proposals for Market Acceptance
• AEP, CPE (Option A), Entergy and Oncor
– CR sends 650_01 to TDSP requesting off-cycle read
– TDSP sends 650_02 to CR with read data
– CR sends 814_PC to update Customer Info
– TDSP sends 814_03 Monthly to ERCOT
8
Same CR Move-in
• In Progress– Development by CPE to implement Option B
• CPE (Option B) 6-8 Weeks– CR sends 814_03 to CPE with Special Flag– CPE sends 814_04 to CR – CPE sends 867_03 Final and 867_04 Initial to CR– CPE sends 867_03 Monthly to ERCOT
– Development by TNMP to implement their option• TNMP 30-60 Days
– CR submits “flat file” request for meter read– TNMP responds with “flat file” containing meter read
• Next Steps– TDSPs to communicate certification procedure with CRs– Immediate Implementation of options using 650 Transaction
• Entergy must have ROA in place – Negotiating with PUCT
9
Macro Plan for Move-in/Move-outLong-term Solution

processing for Texas Market – Address the market events represented by the 29 scenarios previously
identified• Some may be fully automated and some may involve more manual
processes
• Proposed Solution– Establish market participant core Task Force– Develop Detailed Requirements Document– Solicit input/responses from vendors through an RFP– Summarize vendor responses for Task Force review – Recommendation to RMS on vendor short list– Vendor presentations to Task Force – Present final recommendation to ERCOT Board– Negotiate and award contract
10
Macro Plan for Move-in/Move-outLong-term Solution
• Deliverables– Detailed Requirements Document– RFP – Vendor Proposals
• Resources and Costs– TBD by task force
11
Macro Plan for Move-in/Move-outLong-term Solution
• Timeline– RMS and Board approvals to proceed (8/20/02) – RMS establishes Task Force (8/29/02)– Develop Detailed Requirements Document for RFP (tbd)– Review with RMS detailed requirements (tbd)– Release RFP to vendors (tbd)– RFP responses due from vendors (tbd)– Summarize vendor responses for Task Force review (tbd)– Recommendation to RMS on vendor short list (December meeting)– Vendor presentations to Task Force (tbd)– Vendor recommendation to ERCOT Board (tbd)– Begin contract negotiations (tbd)– Award contract (by end of Q1/2003)

Market Synchronization Activities
19
• Objective – Address market issues resulting in an out of sync “Rep of Record”
between ERCOT, TDSP, and CR systems for all ESI IDs
• Completed Items– Programs to compare and report discrepancies are complete– MP agreed upon approach resolution for 22 scenarios at July 26th
design meeting– Technical review has been completed on two rounds of test files
• In Progress– Letter to TDSPs and CR requested:
• Technical and business project contact person from each company,• Estimated time and date the MP will submit synchronization files
– Internal data synchronization
.
Market Synchronization Retailer Synchronization Project
20
• Next Steps– By August 1st ……. Test run with encrypted files
– August 10-11 …….. All TDSPs & CRs MUST compile files
– August 12th……….. All files received by ERCOT
– August 13th……….. Status report conference call (go forward decision)
– September 5th …… ERCOT to identify out-of-synch results
ERCOT will host 2nd design meeting to prioritize and
define correction criteria
– September 10th….. RMS go forward/process decision (e-mail vote)
– October 3rd …… Escalate issues to TAC (if required)
Market Synchronization Retailer Synchronization (continued)
21
Market Synchronization – Non Price to Beat
• Objective– Make necessary corrections to ensure that >1MW Customers were
switched on the correct date in January 2002
• Completed Items – Number ESI Ids (>1 MW) Identified by CR’s 1,040– Number of ESI IDs that are corrected 836
(80%)
• In Progress (as of July 31st – to be updated)– Number of ESI IDs where CR matches but date does not 128 (13%)
(TDSP and Retailers to agree to date)– Number of ESI IDs where CR is not CR of record 76 ( 7%)
(TDSP and Retailers to agree to switch & date)
• Next Steps– Escalate ESI IDs not agreed upon
22
IDR Meter Data
23
• TDSPs and ERCOT working to improve IDR data completeness
• ERCOT developed an enhanced “IDR Data Status Report” which was delivered to TDSPs starting on 7-17-2002
– Identifies any IDR ESI ID that has ever been active and associated load data
– Includes all ESI ID Service History row to facilitate 867_03 date matching
• In special circumstances, ERCOT has deployed alternative data loading mechanisms to fill gaps and bring IDR data current in Lodestar

Retail Portal Performance
32
Portal Performance Items
• 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% decrease in timeout errors– Also added “heartbeat” functionality to verify EAI every minute
• Implemented additional redundancy improvements 6/8– Improvements in redundancy (6) for find transactions– Limited the result set to 500 transactions
• Change made to Find ESI ID 7/28– Moving Siebel queries directly to Oracle– Only 2 errors in the last 3 days (99.8% success!)
• Future options being evaluated– For Find Transaction – move directly to Oracle (ETA is August 19th)– Additional redundant paths for Portal transactions (if needed)
33
Quick Recovery Team Update
34
Quick Recovery Effort
Focus: Problematic transactions that are required by the CRto generate end-use customer bills.
Period: December 17, 2001 – May 31, 2002
For transactions/issues outside of this date range, MPs mustcreate a FasTrak issue and contact their Registration Analystfor resolution.
35
Quick Recovery EffortProgress
•Created market website to track QRE progress by MP, root cause, etc. http://etod.ercot.com/QRECharts.asp?
•Database supporting website also acts as an audit trail for all QRE activities.
•Interviewed all TDSPs to determine procedures forhandling back dated move ins and move outs during therecovery effort.
•Provided TDSPs access to a report to close the information loopand let them know when ESI Id issues have been resolved.
•Consolidated all requests for information and/or data from QRE to TDSPs into one spreadsheet with common format.

POLR Rule Background
• A PUC rulemaking is in advanced stages to revise the POLR rule for implementation by January 2003
• Major changes in the draft rule:– AREPs assume role of POLR for non-paying customers at PTB with
disconnection rights– Existing POLR non-pay customers to be transitioned to the AREP– Default POLR service for reasons other than non-pay to be bid competitively
– PUC Staff’s recommended final rule and an implementation timeline will be considered at open meeting August 23, 2002
