  2. History of Performance Measures • Performance Measures were initially created by the PUC to provide transparency into the transaction flows between market participants. • There are three projects that have been used by the Commission for Performance Measures Reporting: • PUC Project 24462 – first Performance Measures Rule • PUC Project 33049 – second Performance Measures Rule – effective July 1, 2008 • http://interchange.puc.state.tx.us/WebApp/Interchange/application/dbapps/filings/pgControl.asp?TXT_UTILITY_TYPE=A&TXT_CNTRL_NO=33049 • PUC Project 36141 – Project to file Performance Measures – for filing • http://interchange.puc.state.tx.us/WebApp/Interchange/application/dbapps/filings/pgControl.asp?TXT_UTILITY_TYPE=A&TXT_CNTRL_NO=36141 • The PUC rule defines what is to be reported. The Market Metrics Working Group worked together to create templates so the filing package of each participant is consistent in appearance. • These documents are ERCOT management reports to the Commission. ERCOT provides a copy of company specific materials to market participants. • Because of the confidential data contained in the report, reports to market participants go to one place, the Siebel Primary Contact.

  3. Helpful Info • Market participants, CR and TDSP, receive ERCOT reports. They have a responsibility to validate that the statistics are reasonable and are to file a dispute with the Commission if there is a material discrepancy. • It should be understood that statistics may not match exactly. Because of reporting system designs, data may be slightly different. Timing also causes slight differences. • ERCOT uses a weighted average in the calculation of protocol for the month and the quarter. One day may not make a dramatic swing in the percent in protocol from a total market perspective. • CR and TDSP have requirements for their filings in the same rule.
