Participation in the EDS 3 Testing Phases (Section 1.4 – EDS 3 Plan)

Market Participant Type Activities Timeframe Expectation

QSEs with resources planning on utilizing API’s in production

MP Development Connectivity Testing (Sandbox)

July - September Strongly Recommended

MP Connectivity Testing (EDS Environment)

July - September Strongly Recommended

MP Connectivity Testing (EDS Environment)

October Mandatory *

MP Input Validation – SCED Aug – September Strongly Recommended

MP Input Validation – SCED October Mandatory *

MP Input using SCED User Interface October Recommended **

All QSEs with resources

MP Input using SCED User Interface July – September Recommended **

MP Input for SCED Execution October – December Mandatory for designated EDS testing days

MP Input for 6 month LMP Period January – June 2008 Mandatory based on define scenarios and methodology

QSEs with resources not planning on utilizing API’s in production

MP Input using SCED User Interface October Mandatory *

* Starting in October Market Participant involvement is critical to begin producing “Reasonable” LMPs. During this period the Market Participants should have a partial EDS system in place to support the activities and functionality being demonstrated. The EDS team will provide workshops during this time to support Market Participants. Required Market Participants that are not able to participate will have to still perform these activities by requesting a ‘make-up’ workshop prior to involvement in later EDS activities. There will be limited opportunities for support due to focus on other EDS functionality.** The EDS team recommends that all QSEs with resources schedule some time to get familiar with the SCED user interface even if they are planning on utilizing APIs in production. This will help ensure that Market Participants have a second method for accessing the EDS systems if their APIs are not functioning correctly.

Transition Plan Details Development Schedule

Transition Plan Requirement Presentation to TPTF

Approval by TPTF

Develop a method for Market Participants to create and provide individual Resource offer curves to SCED

Identify MIS reporting requirements – “posting LMPs and other data available on the EDS…” if required in NP 6.3.2

Define LMP posting requirements – what does “at least six months” mean? What LMP analysis and feedback requirement?

Define a method for Load Frequency Control Testing, including the plan for settlement of nodal testing periods (Compliance involvement)

Create a CRR detailed test plan describing each step of trial allocation & auction

Define PCRR / CRR allocation process for testing

Calendar of Registration Documentation• Aligning Registration Dates to coordinate with EDS

Milestones:• Resource Registration data (fully-certified version)

– Provide to ERCOT by 9/1/07– In time for 10/1/07 mandatory EDS3/SCED testing

• Attestation for Qualification of Ancillary Services– Provide to ERCOT by 9/1/07– In support of LFC testing preparation/scheduling

1/1/08• Sign MP Standard Form Agreements

– Time of BOD approval for PRR/NPRR, not EDS– Estimate BOD approval in place by 10/1/07– Target completion 60-90 days later

• CRR Account Holder Application– Provide to ERCOT by 3/1/08– In time for 4/1/08 testing of CRR Auction

• QSE Application (new QSEs)– QSEs with Resources (August 2007)– QSEs without Resources provide to ERCOT by

3/1/08– Receive by 3/1/08, in time for 4/1/08 testing of DAM

What is Data is needed to support EDS3?

Resource Data is needed for EDS3-SCED Testing

• What ERCOT has:– Zonal Generation Asset Registration Forms (GARFs on file at ERCOT)

• What ERCOT does not have:– Subset of new resource parameters for nodal market (not on file at ERCOT)

• ERCOT’s plan to get EDS3 Resource Data established in nodal systems– In the short term (for pre-EDS3 testing), ERCOT is to release a

spreadsheet to QSEs and/or Resource Entities to complete the “bare-bones” list of Resource data needed for data entry validation

• ERCOT will upload data into Market Management System (MMS)

– In the longer term (for mandatory EDS3 activities), ERCOT is to release a new version of the Resource Asset Registration Form to Resource Entities to have completed and on file at ERCOT

• ERCOT will release new Resource Asset Registration Form (and upon request can provide the zonal GARF that is on file)

• New form will highlight new data elements needed


Texas Nodal

Nodal Sandbox/Interface Testing Environment

• Purpose of Sandbox

– Allow Market Participant developers (and vendors) to access ERCOT programmatic interfaces and test code for data submission

• Limitations/advantages of sandbox

– Not an EDS environment

– No data validation, only technical validation of code and format

Nodal Sandbox/Interface Testing Environment (cont’d)

• Limitations/advantages of sandbox (cont’d)– Environment is already available to the market for testing– Developer can use Sandbox to shake-out coding issues– Developer can use Sandbox to resolve security/digital certificate issues

• Allows technical testing prior to pre-EDS and EDS activities• Market Interface document available as Machine-to-Machine Interface (

Summary and Questions

Readiness Summary:• Sandbox/Interface Testing Environment is already available to test

submission of some transactions– No Resource data needed as there is no data validation

• To obtain Resource Registration Data, ERCOT is planning to release draft of Resource data to TPTF by June 1, and plans formal release of registration forms to market by June 28.

– Pre-EDS3 participants will need to provide “bare-bones” list of Resource data

– Mandatory EDS3 will require full completion of Resource Registration Forms (9/1/07)
