ESI ID Tracking System (ETS)

ETS

Phase I

• Objective– Develop a system to track complete ESIID life-cycle– Maintain ESIID data until transaction life-cycle is complete

• Completed– Detailed Requirements Gathering – Functional and Technical Design Documents– First Draft Design of System Reports

• In Progress– Mock-up of internal reports and user interface– Development and production hardware on order

• Next Steps– Build Phase on schedule to start August 5, 2002

ETS

Phase II

• Objective– Develop a system to allow Market access into ESIID transaction life-cycle

data

– Maintain ESIID data until transaction life-cycle is complete

• Completed– Received information from 13 Market Participants on display data elements

• In Progress– Summary of Market display data elements to be distributed for review

– Requirements Document for Phase II In Progress

– Mock-up of Market Reports and User Interface In Progress

• Next Steps– Project funding approval from ERCOT Board of Directors

TX SET Version 1.5

TX Set Version 1.5

Market Synchronization Activities

• 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– ERCOT continues process of internal systems synchronization

.

Market Synchronization Retailer Synchronization Project

• 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)

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 1,004– Number of ESI IDs that are corrected 742

(74%)

• In Progress– Number of ESI IDs where CR matches but date does not 45 ( 4%)

(TDSP and CR to agree to date)– Number of ESI IDs where CR is not CR of record 72 ( 7%)

(TDSP and CR to agree to switch)– Number of ESI IDs with missing analysis data 145 (15%)

(ERCOT to follow-up with TDSP and CR)• Next Steps

– Escalate ESI IDs not agreed upon

IDR Meter Data

• 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

• ERCOT has provided load data exports in LSE format for TDSPs entire IDR population

• In special circumstances, ERCOT has deployed alternative data loading mechanisms to fill gaps and bring IDR data current in Lodestar – TDSP has confirmed the missing Lodestar data is available and has been

provided to CR and

– TDSP has confirmed the data being provided for loading is identical to the data provided to the CR .

Quick Recovery Team Update

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.

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.
