Testing Preparation – Confirming Schedule

By May 30th

– Confirm testing schedule with ERCOT for each MP.– MP must confirm number of testing resources available during

scheduled time slot.– For any other questions or issues that need to be addressed,

ERCOT will schedule a call with the MP as needed.– POC for EDS 1 Testing - Contact Jonathan Pulcini at

[email protected] to schedule testing.


Testing Preparation – Pre-Testing Activities

Four Weeks Prior to Testing– ERCOT sends the Market Participant (MP) the AIEF form to

complete.– The MP emails the ICCP team a completed AIEF form to Steve

White at [email protected].– ERCOT sends the MP an ICCP Change Request Form pre-

populated with existing Zonal ICCP points.– ERCOT completes all network requests and verifies network

connectivity with the MP.

Note: these steps have already been completed for CenterPoint Energy



Three Weeks Prior to Testing– MP submits the ICCP Service Request:

• link http://nodal.ercot.com/readiness/eds1/documents/index.html

• as a Service Request (SR) through the Texas Market Link (TML)

• with all new ICCP points using the pre-populated service request form sent by ERCOT the previous week.

Note: ERCOT requests that MPs submit SRs to TML early in the week to give ERCOT time to review the list and load changes into their Wednesday database batch load

– MP sends:• detailed schedule (list of stations/resources to test each day)

• number of resources available

• testing contacts (name, phone, email)

– ERCOT loads existing SCADA points into EMS database as part of the weekly Wednesday batch load.



Two Weeks Prior to Testing– ERCOT loads new ICCP data points for the MP into ICCP test

database.– EDS 1 testing team loads ICCP testing data points into EDS 1

testing database.– ERCOT generates and sends test checklists to the MP for

verification.– MP sends ERCOT one line diagrams (if available) for all

stations/resources that will be tested.



One Week Prior to Testing– ERCOT re-confirms testing schedule with the MP.– ERCOT updates testing checklists and resends to the MP.– ERCOT conducts a pre-test with one MP station/resource

scheduled for testing the first week.

Note: Testing will consist of verifying status changes on a unit, reviewing randomly selected analog points, and manually changes some points. The MP must have at least one resource available to conduct pre-testing.


Testing Preparation – Testing Activities

P2P Testing– ERCOT records the MP operator name, contact information, and

start time of the test on each test checklist.– ERCOT cross-verifies with the MP all analog point values and

quality codes on both ends.– The MP changes values of selected analog points on their side

and ERCOT verifies changes in value, quality code, and update time at ERCOT.

– The MP toggles status of each status point. ERCOT verifies status change, change in quality code and time taken for update on tabular displays.



Immediately Following Test– ERCOT logs, categorizes, and prioritizes all the identified

problems. – ERCOT sends an electronically signed copy of the test

results to the MP through email.– MP emails confirmation and agreement of the ERCOT

electronically signed copy to [email protected]– ERCOT provides a weekly status on testing results to track

progress at:• http://nodal.ercot.com - Readiness Center tab, Key

Documents• EDS 1 Weekly Status Report mmddyyyy.doc



EDS 1 Weekly Status Report - example


Testing Preparation – Post-Testing Activities

Week After Testing– ERCOT updates central EDS 1 testing database with test results. – ERCOT updates issue list database based on the issues

identified and assigns them either to ICCP analysts or network modeling teams.

– ERCOT ICCP/Modeling teams work with the MPs to resolve problems.

– EDS 1 team re-verifies the issues at appropriate time and updates the databases.

QSE Nodal Point VerificationJohn Webb and Ken Kasparian


Nodal QSE SCED / LFC Point Verification Plan

Background– Each QSE will add approximately 30 new SCED / LFC ICCP

points per Resource (Unit and Load)– New points are defined in the ICCP Handbook in tables 20 and

26-31

EDS 1– Scope

• Load new and existing points into the Nodal ICCP database• Verify ICCP connectivity, point mapping, scan rates and

quality code values between QSEs and ERCOT– Inbound to ERCOT

• QSE Operator manually enters / toggles values for ERCOT Operator to verify

– Outbound to QSEs• ERCOT Operator manually enters / toggles values for QSE

Operator to verify


Nodal QSE SCED / LFC Point Verification Plan

EDS 3– Scope

• Trial Operation of Security Constrained Economic Dispatch (SCED)

• Attain Reasonable LMPs & Begin Six Month LMP Posting• Trial Operation of Load Frequency Control (LFC)

– Inbound to ERCOT• Real-Time ICCP point data required for SCED / LFC

– Outbound to QSEs• EDS 3 SCED / LFC ICCP point data


Step 1(Jun – Sep 07)

Step 2(Aug – Oct 07)

Step 3(Oct – Dec 07)

ICCP Validation• Point to Point Checkout• Configure New ICCP Data

Registration Data Collection• Validate Existing Data• Collect New Registration Data

Web Services• WS Interface Specifications• Development Sandbox

SCED ICCP Input• Connect new ICCP data sources (EMS, Field Telemetry, …)• Validate new MP ICCP telemetry is available for SCED testing

Registration Data• Upload New Registration Data for Nodal testing• Complete Registration Data Integration

Web Services• WS Backend Integration• MMS Validation Rule Testing (Early EDS)

SCED Execution• Nodal Registration Data• Static ICCP data inputs to validate initial stability• Migrate to Real-Time ICCP data inputs for SCED testing• Reasonable LMP Attainment

SCED ICCP Output• Complete Integration with EMS system• Distribute SCED outputs via ICCP

Web Service Output• Distribute SCED output via Web Services

Step 4(Jan – Jun 08)

LMP Posting• Post LMPs for 6 months as required by the Nodal Transition Plan• Utilize Real-Time ICCP data• Distribute SCED outputs via Web Services & ICCP

EDS 3 - Data Preparation for SCED 6 Month LMP Posting

ICCP HandbookBill Blevins and Frank Kendall


ICCP Handbook Changes Summary

• This ERCOT Nodal ICCP Communication Handbook Version 0.20 is a major revision from the previous Version 0.11. Changes have occurred in every section and nearly every paragraph.

• The document has also been organized so that material is easier to find, easier to use as a reference document, and to improve comprehension.


ICCP Handbook Change Summary Details

• All comments from ERCOT internal review, TPTF, and other Market Participants have been processed.

• The AIEF has been modified and moved to Appendix A. • There is now only one version of the AIEF regardless of Market

Participant type.• An explanation of the ICCP Object Naming conventions and the

purpose of the naming convention tables versus the data exchange tables has been added (Section 1.4).

• The ICCP Object Naming convention tables have been moved so that they are adjacent to the data exchange tables they support.

• The ICCP Object Naming conventions have been changed to make constructing an object name easier.

• The glossary has been expanded (Section 1.6).


ICCP Handbook Change Summary Details

• Section 2 has been improved and combined with the section on implementation procedures previously duplicated in the QSE and TSP sections.

• The description of the high data availability architecture has been given its own chapter level section (Section 3) and greatly expanded to discuss various Market Participant configurations, connections, and operation in the new architecture.

• Domain naming conventions have been changed to support the high data availability architecture, and the section has been reorganized for improved clarity (Section 4.3).

• Resource status codes have been defined and included in the Handbook (Section 4.5.2).

• Other improvements in clarity have been made throughout the document.


ICCP Handbook Next steps

• Address TBD issues.• Post version 0.21 for TPTF approval.• May 22nd review comments and resolution with TPTF.• Obtain vote from TPTF for approval.• Place ICCP handbook under document control.• Deliver to IRT for EDS P-P checkouts.• Distribute to Market Participants.
