Current Status

• Targeted this RMS meeting for “Base” process preferences/recommendations– Retain ESI or Replace/Retire ESI

• Task Force:– has not yet reached consensus

– has had additional discussion re: need to continue work

– has requested PUCT staff input

Transition Process Alternatives

• Seven process alternatives are being considered– Retain original ESI for service delivery point and transition that ESI from

“losing” TDSP to “gaining” TDSP;

• Alternative X1 – new 814_20 that changes TDSPs

• Alternative X2 – new transaction to switch/drop TDU

• Alternative X6 – manual process to be defined

OR

– Establish new ESI for service delivery point, transition retail service from old ESI to new ESI, retire old ESI

• Alternative X3 – Use existing move in and move out transactions

• Alternative X4 – new 814_20 that copies/creates new ESI

• Alternative X5 – new ESI transfer transaction

• Alternative X7 – manual process to be defined

Transition Scenario Variables• Variables that were determined to be important in developing recommendations for

the business processes and transactions to use include:– Time Frame

• Short Term (prior to new trx) vs. Long Term (post system changes) – Transition Date

• Date certain vs. on cycle vs. off-cycle– Volume of ESI IDs in transition

• < 500 • 501 to 5000• > 5000

– “Gaining” TDU territory competitive status• Opt-In IOU vs. Opt-In MCTDU vs. Non Opt-In

– “Losing” TDU status in market• Maintains a presence in Texas market vs. exits Texas market

– TDU tariff applied by “Gaining” TDU• “Gaining” TDU tariff vs. “Losing” TDU tariff vs. N/A

5

Alternative Evaluation CriteriaPotential evaluation criteria

– Impact on customer• Ongoing service (billing etc..)• Impact on Choice

– Lead time for implementation– Cost

• Development• Maintenance• Execution• Post Execution

– Cost per use– Degree of difficulty– Impact of future market activity– Existing Market Constraints

• Protocol Revisions• TX SET Versions• Regulatory Rules

– Impact on Day to Day Processing• Transaction Volumes• Monitoring• In Flight Transactions or Processes

Market Survey

• Request for market participants (and ERCOT) to express an initial preference for the appropriate process alternative for a designated scenario (specified combination of variables) and in consideration of the proposed evaluation criteria

– Retain or replace

– Given that preference, which process alternative should be applied
