Processing Large Volumes814_20s
Issues / Discussion / Ideas
2
Background of Issue
• At May TX SET and June RMS – TXU ED brought forward questions related to processing large volumes of 814_20s.
• Request of TXU ED at June RMS – – Establish a task force to:
• Establish future volumes and processing requirements
• Evaluate current TIBCO project to determine capabilities
• Determine options for increasing ERCOT processing
• Explore other transactions or other Market Notification processes
• At June RMS – ERCOT said we would discuss internally and bring back ideas to help RMS leadership determine next steps.

Large Volumes / Business Reasons
• Potential business reasons for large volumes of 814_20s– All TDSPs - Annual Validation
– All TDSPs - T & C’s requirements for duplicate address clarifications
– All TDSPs - Retirement of temporary accounts (volumes may vary by TDSPs)
– TXU ED - Rate Expansion – approx. 3,000,000 accounts (weekend conversion)
– TXU ED - On going conversion of AMR project over next 5 years
– TXU ED - Future rate and franchise changes processes

Current Processes
• Load Profiling Guide outlines the process for annual validations. The TDSP and ERCOT work together on schedule to process large volumes– For 2006 – approx 867,000 will be sent
• Approx 200,000 per weekend – across 4 weekends (Fri/Sat/Sun/Mon)
– Future volumes expected to drop to approximately 300,000 per year
– ERCOT process capabilities for 814_20 maintenance transactions are currently between 25K to 50K transactions daily.

Ideas to Consider
• Draft protocol language to address large volumes for business reasons other than annual validation – may want to consider the plan of coordination between TDSPs and ERCOT
• After protocol changes are approved, then ask TX SET to look at – New file format for large volumes of 814_20 maintains to be sent in 'mass
update file' to load at ERCOT
– New file format for large volumes of 814_20 maintains to be sent to CRs to communicate ‘mass update file’
– Additional type of 814_20 maintain – separate out information that needs to be sent to ERCOT or CR only
• Ask ERCOT for additional analysis after implementation of TIBCO, (in Jan 2007) with volumes and timings
• After Nodal system design, explore processing window changes (uncouple from batch)
