Kick Off Market Call

Kick Off Market Call



• Window Assignments by Resource Type– Each Non-PUN / Non-Wind Site will “sign-up” for the June or September Window via

[email protected] email by 6/8/09 for submittal of Transmission and Planning / Protection data

– Private Use Networks will submit Planning / Protection Data during the June Window– Wind resources will submit Transmission and Planning / Protection data during the

September window

• Approach for this phase will be similar to the resource data collection in 2008– Each Window will be broken up into 3 iterations each with increasing goals of

production quality • Iteration 1 – 85% production quality• Iteration 2 – 95% production quality• Iteration 3 – 98% production quality

– Iteration 1 will begin with ERCOT sending each RE assigned to that iteration a pre-populated RARF and an audit report

• Audit reports will detail each error in the RARF and the violated business rules• ERCOT will provide pre-populated RARF’s containing data previously submitted through various artifacts

(transmission data slides will discuss in greater detail)• This pre-populated RARF must be used going forward for all changes• Each RE’s Account Manager will schedule a formal conference call to discuss errors on the audit report



• Approach for this phase will be similar to the resource data collection in 2008 (continued)– Iteration 2 and 3 will include interim audit reports as revisions are

submitted by RE’s– Account Manager’s will schedule conference calls in iteration 2 and

3 on an as-needed basis – At the close of each iteration a formal production quality metric will

be published to the readiness center– A dashboard with the status of each RE will be published weekly

• The June Window will officially begin 6/15/09– RE’s will receive their pre-populated RARF’s the week of 6/8– ERCOT Account Managers will schedule calls to start the week of

6/15– Further schedule details discussed in the “What’s Next?” section

Registration Audit Process


Project Logistics - RARF Screening Process / Reference Materials

• Business rules used in the audit report will be published in the Resource Registration Guide

– Currently these have been added for the transmission data sections

– Planning and Protection data changes will be published by 6/8/09

– Each section contains a short narrative regarding that section

– Each also section contains all screening business rules that will be applied to each field in the RARF

– ERCOT will also be working to make these modifications to the resource data sections in the guide as well (data elements filled out last year). This will be completed at a later date.

– The Resource Registration Guide URL (last document under Key Documents section):http://nodal.ercot.com/readiness/rq/documents/index.html


Data Collection Details - Transmission Data

• Transmission Data Tabs Background

– These are derived from 2 artifacts1. TDF (Transmission Data Form) used in zonal and MP-10

2. GSU Transformer and Transmission Assets tabs revamped from the original RARF

– These artifacts were then integrated into the RARF at the request of TPTF(reviewed by TPTF in September 2008)

– Some fields were added / removed based on ERCOT data requirements

• Resource Entities have provided much of this data in previous activities

– This effort will focus on closing gaps and validating data already provided

– Audit Reports will detail only errors or warnings. RE’s should review all pre-populated data to ensure accuracy in previous submittals



• Process of Pre-populating RARF’s– Initial population baselines data from the zonal model, including updates made

through the MP-10 process– The process then updates this baseline with data submitted via the old GSU

Transformer and the Transmission Assets tabs – In short, ERCOT will provide all data we have on file to Resource Entities in a pre-

populated RARF.

• Common issues encountered during preliminary transmission data reviews: – Device names (lines, breaker, transformers, etc) do not match the ERCOT

Mnemonic• In these cases, ERCOT cannot update data submitted via RARF• We will have to work with Resource Entities individually to resolve these

– One-lines do not agree with registered assets (resources, transmission data, etc)– In some cases it was not possible to distinguish between TSP and RE owned assets

• In these cases, RE’s are asked to simply remove them from their RARF• Most commonly these are lines going from a Gen Site to a TSP substation



• Inventory of Transmission Data Forms (high level lists)– Lines– Breakers and Switches– Capacitors and Reactors– Transformers– Static Var Compensators– Series Devices– Load Data

(non-puns will provide Aux / Site Service Load)– * PUN Load 168 hr Profiles (private use networks only)


Data Collection Details - Planning and Protection Data

• Planning and Protection data was originally targeted for later this year / early 2010– Schedule accelerated in order to minimize iterations with Resource Entities– Schedule accelerated also to avoid conflicts with other activities such as re-

qualification of QSE’s and Market Trials

• The following changes made to the planning and protection data:– Planning:

• Several data elements removed from generator details• Generator Auxiliary Load is now optional except for Combined Cycle Units• PSSE Model files

– Method of submittal will now be a zip file accompanied by the RARF submittal in the SR (or alternative email process)

– Some files are noted in the RARF as optional based on the details of that site– Note that the PSSE templates are located at

http://www.ercot.com/gridinfo/generation/

– Protection• Only change is adding a 4th time point to each section (Underfrequency, Overfrequency,

Overvoltage, Undervoltage)

– Note that all changes will be included in the pre-populated RARF sent to all RE’s at the start of either the June Window or September Window


Data Collection Details - Planning and Protection Data

• Business Rules for Planning and Protection– ERCOT team is in the process of adding these to the Resource

Registration Guide– This will be complete and published to the market by 6/8/09 to the

readiness center– Posted at http://nodal.ercot.com/readiness/rq/documents/index.html

under Key Documents


Data Collection Details - Sub Synchronous Data

• Sub Synchronous data will be required of Resource Entities that have already collected this data

• For Resource Entities that do not have this data available, it will be required at a later time if their site is impacted by / included in a Reactive Management Study\– Note that RE’s can follow current RFP’s by reviewing the status

updates provided to the Regional Planning Group (RPG)• RFP for Study may define additional data from RE’s beyond that

which is requested in the current RARF form• There are no changes to this RARF tab


Data Collection Details - Load Resource Registration Changes

• NPRR162 - Change the Sign Convention of Net Real Power Consumption, LPC and MPC of Load Resources (formerly titled “Change the Sign Convention for Load Resources”)– Previously Load Resources Have submitted these values as

negatives number to signify consumption– ERCOT systems require that these be expressed as positive

numbers– ERCOT has temporarily changes this in the model. – Load Resources need to officially make this modification to their

Load RARF• ERCOT requires that each Load Resource be mapped to a

physical TSP load– ERCOT will compile information it has available and contact each

registered Load Resource Entity to confirm and update their Load RARF


Next Steps –

• All non-PUN / Non-Wind sites must send an email to [email protected] “signing up” for either the June Submittal Window or the September Submittal Window by 6/8/09

• Current Sign-ups of Non-Pun / Non-Wind for June Window:– CITY OF GARLAND– GEN TEX POWER CORP– LOWER COLORADO RIVER AUTHORITY– LUMINANT GENERATION COMPANY LLC– OAK GROVE MANAGEMENT COMPANY LLC– BIG BROWN POWER COMPANY LLC– COLLIN POWER COMPANY LLC– SANDOW POWER COMPANY LLC– TRADINGHOUSE POWER COMPANY LLC– VALLEY NG POWER COMPANY LLC


What’s Next - June Window Schedule

• Receive Audit Report and pre-populated RARF week of 6/8• Conference call with Account Managers starting week of 6/15• Iteration 1 corrections due 7/13/09 (20 business days)• Iteration 2 corrections (if needed) due 8/12/09 (15 business days)• Iteration 3 corrections (if needed) due 9/1/09 (10 business days)


What’s Next - September Window Schedule

• Kick off for September Window 8/28/09

• Receive Audit Report and pre-populated RARF 9/1/09

• Conference call with Account Managers starting week of 9/8

• Iteration 1 corrections due 9/30/09 (20 business days)

• Iteration 2 corrections (if needed) due 10/27/09 (15 business days)

• Iteration 3 corrections (if needed) due 11/16/09 (10 business days)


What’s Next – Remaining MP-10 Activities

• This will be further detailed at a future WebEx

• Background– MP-10 began in 2008 with initial validation of one-lines, gen site

topology and mapping to EPS meter(s) and resource node(s)– RE’s were sent MP-10 and asked to respond with required changes– Early 2009 ERCOT executed changes and in some cases identified

re-work required by RE’s– September 2009 (Post SEM Go Live) RE’s will be asked to:

• Perform final verification on changes made by ERCOT<OR>

• Perform re-work so that ERCOT changes can be completed


Next Steps – Updates and Communication

• ERCOT will be hosting a market call every 2 weeks– Standing Agenda:

• Project Updates

• Production quality metric

• Common issues / Frequently Asked Questions

• Q&A

• These meetings will be our primary means of communication

– These meetings will continue to be posted to the Registration and Qualification calendar at http://www.ercot.com/committees/nodal/rq/ The next Registration Market Call will occur on Friday 6/05/09

• All questions should be routed to [email protected]– Questions sent directly to your Account Manager, should also copy

[email protected] as well
