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.


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. 2

  • Special Topics
    • Engaging Remaining Resource Entities
    • Planning, Protection and SubSync Data Collection
  • Reminders
  • Q&A / Open Forum

ERCOT asks that you log into the WebEx using your company name then your name. This will allow us to take roll call offline. If you have not logged in with your company name, please use the WebEx chat to tell the host your company is represented 3

updates and progress
Updates and Progress
  • Status for the past week:
    • Continued to work with several RE’s via conference calls
    • Iteration 1 completed / Iteration 2 audit reports have been sent
      • RE’s received an audit report if:
        • You have errors that still exists or new errors
        • You have warnings (no action required for warnings)
        • Note – those that did not turn in a RARF for iteration 1 did not receive a new audit report
    • Current PUN Transmission Production Quality Metric is at 89%
      • Up from 86% last week
      • RARF’s Received for Iteration 1 Deadline: 14
      • RARF’s Accepted for iteration 1 Deadline: 1
      • Those that were rejected had very minor issues
      • Total RARF’s Accepted: 1 of 23 (several in the last stage of modification) 4

updates and progress1
Updates and Progress
  • Where are we at?
  • Calls to RE’s will continue through iteration 2 (unless RARF is accepted)
  • Iteration 2 started on time 4/6/09
  • Iteration 2 RARF’s are due by EOB 4/27/09
  • Continue to use for questions or to request a conference call to review your audit report 5

special topics engaging remaining resource entities
Special Topics – Engaging Remaining Resource Entities
  • ERCOT Will be Dividing the Remaining Resource Entities into 2 Submission Windows
    • Dividing into two windows allows ERCOT to spend more time assisting with MP registration issues
    • There is no change to the final RARF data collection end date (12/31/09)
    • These windows will include Planning, Protection and SubSync data
      • Previously this was out of scope for the transmission data collection phase
      • Completing this now will reduce the risk of completing at the end of the year as a separate process
    • ERCOT will ask RE’s to request inclusion into Window 1 or Window 2 at the next Friday Update Call.
    • As slots fill, ERCOT will make every effort to honor requests, but may have to change it based on capacity 6

special topics engaging remaining resource entities1
Special Topics – Engaging Remaining Resource Entities
  • Window 1
    • Begins June 1 ending on Sept. 1
    • This will be available to all technologies except Wind
    • Wind resources will be addressed during Window 2
      • WOTF are reviewing potential changes to wind registration data
      • ERCOT will address Wind Resources once these changes have been solidified
  • Window 2
    • Begins Sept 1 ending on Nov. 1
    • All Wind Resources will be in this iteration
    • There will be capacity for other resource types, but more limited than Window 1
  • ERCOT will host a market kick off meeting for both windows
    • Window 1 kick off meeting is currently targeted for the 5/22/09
    • Kick off will take the place of that week’s market call
  • Market calls will continue to be hosted by ERCOT on a bi-weekly basis through the end of Window 2 7

special topics planning protection and subsync data collection
Special Topics – Planning, Protection and SubSync Data Collection
  • Planning, Protection and SubSync Data is the last of the RARF data collection categories
  • Originally schedule for late 2009, it will be rolled into the transmission data collection process
    • For Private Use Networks that have already completed the transmission data collection, they will have the option of providing the planning, protection and subsync data in either Window 1 or Window 2
  • ERCOT is reviewing the supporting tabs in the RARF and ensuring all data requested aligns with base system requirements
    • RE’s should contact prior to starting these to ensure they are working off of the most recent version of these forms
  • Business rules will be completed for these tabs by mid-may and tested through the remainder of the month
  • These will then align with the previously mentioned Windows for transmission data collection 8


Q&A / Open Forum 9


Appendix 10

reminders originally presented on 3 13 09
RemindersOriginally Presented on 3/13/09
  • ERCOT has published a revised RARF guide
    • The revised RARF guide contains all the business rules for transmission assets
    • The URL where this can be located is:
    • Document title: EDS - Resource Registration Guide v4.2
  • Scope of Transmission Data Assets (high level lists)
    • Lines
    • Breakers and Switches
    • Capacitors and Reactors
    • Transformers
    • Static Var Compensators
    • Series Devices
    • Loads
    • * PUN Load 168 hr Profiles*note that accepted PUN Load 168 hr Profiles will be added to the RARF upon re-submittal Those that still have issues with the PUN 168 profile form, ERCOT will work with you to correct on the conference with your account manager
  • Out of Scope for this phase
    • Protection
    • SubSync
    • Planning 11

reminders originally presented on 3 13 091
RemindersOriginally Presented on 3/13/09
  • Clarifying statements on which assets need to be registered / modeled Note: This is specific to PUN’s. Specifics on other resource entities will be addressed on a later call
    • All assets which are between a generator and the point of interconnect to ERCOT
    • All Load
      • Loads which are connected on a Bus greater than or equal to 60kV need to be modeled individually
      • Loads connected at less than 60kV may be aggregated into an “equivalent load” at the 69kV Bus
      • Auxiliary and Site Service Load may be combinedNote: Auxiliary load is defined as that which is only present when the generator is running
    • In some cases it will be necessary for ERCOT and the Private Network to review specific assets and/or sites to make a determination on whether or not it is required to be registered / modeled
      • These cases will be addressed during a WebEx coordinated by the RE’s Account Manager 12

special topics originally presented on 3 13 09
Special TopicsOriginally Presented on 3/13/09
  • Issues Encountered on initial audit report group
    • Found that some validations were too “tight.”
      • These have been relaxed
      • Will be discussed on the conference call with your Account Manager if applicable to your audit report
      • Example high / low side manufactured voltage on transformers was asking for levels at exactly 69,138 or 345 – it now allows up to 9% deviation from these levels (warns > 5%)
    • Data Pre-population issues
      • Size of each step on transformer high/low tap settings calculated incorrectly
        • ERCOT will calculate this based on data provided by RE
        • This will be ignored if in error on the audit report
      • Transformer Reactance / Resistance incorrectly calculated
        • ERCOT will provide correction to RE’s for first iteration 1 submittal
      • Loads missing on Load tab
        • In cases where PUN’s have multiple substations under a site code, those substations that are not the same mnemonic as the site code did not populate the Load data. ERCOT will send the additional Loads left off 13
