  2. Antitrust Admonition ANTITRUST ADMONITION ERCOT strictly prohibits Market Participants and their employees who are participating in ERCOT activities from using their participation in ERCOT activities as a forum for engaging in practices or communications that violate the antitrust laws. The ERCOT Board has approved guidelines for members of ERCOT Committees, Subcommittees and Working Groups to be reviewed and followed by each Market Participant attending ERCOT meetings. If you have not received a copy of these Guidelines, copies are available at the Client Relations desk. Please remember your ongoing obligation to comply with all applicable laws, including the antitrust laws. DISCLAIMER All presentations and materials submitted by Market Participants or any other Entity to ERCOT staff for this meeting are received and posted with the acknowledgement that the information will be considered public in accordance with the ERCOT Websites Content Management Operating Procedure. http://nodal.ercot.com 2

  3. Agenda • Antitrust Admonition • Environment Report • Planned / unplanned outages • Known Issues • Standing Reports and Updates • General reminders / updates • RTM / LFC Update • LFC Calendar Update • State Estimator Convergence Statistics • Question and Answers / General Discussion ERCOT asks that Market Participants log into the WebEx session using their company name and then their name.

  4. Market Trials 2010 Roadmap http://nodal.ercot.com 4

  5. Environment Report: Planned / Unplanned Nodal Outages Planned Outages • 06/18/2010, 6:00 - 7:30 P.M. (CDT) • Hardware site failover is planned for this period and will affect availability of following application services: • EWS ( Web Services) • OS UI • MM UI Unplanned Outages • 06/15/2010, 12:55 - 1:20 P.M. (CDT) • Application link to Market Manager system was unavailable on the MIS portal due an LDAP synchronization issue. • 06/15/2010 01:00 P.M. - Ongoing • Users are currently unable to view TPO awards via the MM UI. An application defect has been identified as the root cause and necessary fix is being addressed (the report is available as a downloadable file on MM UI and can also be obtained via EWS). http://nodal.ercot.com 5

  6. Known Issues Recently Closed Issues • SPPs_RTM, the time of EWS response is incorrect when EWS connection is through either HTTPS/SSL or Internal URL • The "SPP at Hubs and Load Zones" report when pulled through web services uses an incorrect GMT offset of -6 (should be -5), which is causing the SPP data to line up incorrectly with the timestamp • EIP • This issue fixed in EWS 1.19L, which went to NPROD on June 11. • NP8-501 Monthly Resource Energy Deployment Performance Report (MIS Certified Report) • Additional Language is being added to the Report Info Tab to clarify that Source Data will not always be available for every resource every five minutes; also recommending code changes to appropriately account any missing intervals • EDW http://nodal.ercot.com 6

  7. Known Issues Recently Closed Issues (continued) • Update Weather Data section in EIP External Interfaces Specification to align with CDR Report • In a future update to the EIP External Interfaces Specification, the XML example in Section 4.3.31, Weather Data, will be aligned with the actual CDR Report by removing all weather-data tags except for <temperature></temperature> (the temperature data is the only data that needs to be provided in this report because it is the only data that is used in common by both the load forecasting and dynamic ratings applications). • Corrected in v1.19M (http://nodal.ercot.com/readiness/sandbox/index.html) • Becomes effective July 9 • Update Dynamic Ratings section in EIP External Interfaces Specification • In a future update to the EIP External Interfaces Specification, the "2-hour" rating type identified in section 4.3.16, Dynamic Ratings, will need to be changed to "Emergency." • Corrected in v1.19M (http://nodal.ercot.com/readiness/sandbox/index.html) • Becomes effective July 9 http://nodal.ercot.com 7

  23. LFC – Test Overview & Setup: Quick Start Resources • Deployment of Balancing Energy Service (BES) Capable NSRS for Quick Start resources during the LFC test • Prior to the resource being asked to come online in Zonal, the QSE should: • telemeter a Non-Spin Schedule and Responsibility (NSSC and NSRS) of 0 • telemeter a resource status showing the resource as offline; and • telemeter an LSL of 0 • If the QSE receives an energy deployment in Zonal, the QSE should start that resource and telemeter a resource status of online (ON) as soon as they are capable • Once the resource is “ON” with net MW > 0, the resource will be available for SCED dispatch and the resource will be dispatched based on the energy offer curve • After the resource reaches it’s physical LSL, the QSE should reflect that value through the telemetered LSL and should leave it at that value • Once Zonal indicates that the resource should go offline, the resource should begin ramping down • When the resource goes offline, the QSE should update the telemetered resource status to offline and then change the telemetered LSL to 0 • The QSE also has the option to not provide BES-Capable NSRS during the hours of the test

  24. LFC – Test Overview & Setup: Congestion Management • Manual dispatch instructions during the LFC test • Beginning two hours prior to the LFC test, ERCOT will stop using OC1s and OOMEs and plans to use OC3s to manage congestion • The one exception to this is that ERCOT will continue to use OC1s for the W-N stability limit (non-thermal IROL for NERC) • ERCOT has created and tested a constraint for this limit in the Nodal system which can be activated for SCED as needed and should provide similar dispatch to the OC1s • ERCOT may be required to use Zonal manual dispatch instructions to solve congestion • ERCOT will set the Nodal Base-Point to match the Zonal manual dispatch instruction • The QSE will continue to follow the Nodal Base Point if they are still under Nodal control
