4 Texas Market Model Overview Many internal processes previously owned by the bundled utilities were modified to support retail electric service through Texas electricity deregulation. These processes are now distributed among three groups: TDSP - Transmission and Distribution Service Providers CR - Competitive Retail Company ERCOT - Electric Reliability Council of Texas
5 Market Roles and Responsibilities TDSP Primary Ownership for premise Competitive Retail Co. Primary Ownership for Customer TDSP Primary Responsibilities Transmission & Distribution of Power Read & Service Meters Install, repair and maintain facilities for delivery of power to the customer Bills for Transmission and Distribution charges CR Primary Responsibilities Talks to customers Bills customers Maintains customers Gains/loses customers Purchases energy Settlement processes Collects from customer Payment to TDSP Customer Service Orders (optional) 650 Service Orders: Reread/Meter test 650 Disconnect/Reconnect 820 Payment 650 Service Order Reply: Reread/Meter Tests 650 Disconnect/Reconnect Response 810 Invoice for Wires and Service Charges Note this is a representation of the TX IOU model (ESP Consolidated), the MOU/EC model in Texas can be an LDC Consolidate model.
6 ERCOT Roles and Responsibilities TDSP CR ERCOT EDI Validation Customer Registration/Maintenance Processes (switching, move-ins, move- outs, drops) CR Premise Ownership (REP of Record) Forwarding consumption from TDSP to CR Landlord/Tenant (Continuous Service Agreement) CR Ownership Classification
7 Change Management EDI implementation guide changes are managed by the Texas SET (Standard Electronic Transactions) Working Group. Market Participants request Texas SET to investigate potential changes to current business processes and EDI structures Valid requests are documented in Change Controls Change Controls contain the business process and EDI transaction changes necessary for the request Change Controls are discussed and approved at TX SET meetings Change Controls are published on the TX SET website It is important to monitor the Texas SET Agendas for pertinent information
