MP11 – RARF Submittals by Resource Entities

Since the January 23rd TPTF Resource Registration Update

• Combined Cycle Addendum (2) sent January 28th.

• Sent QSE specific scores on status of resources they represent.

• MP-11 scores were posted February 1st.

• ERCOT resource data validation begin.

• Conducted Combined Cycle Workshop (1/31).

• Addendum one-on-one help sessions.

• Continue to assist with questions from Resource Owners.




MP-11 scores posted February 1st.

GOOD Response

• RED– 27 Resource Entities are RED due to no EDS 4 RARF submitted

or no submittal since November (no planning data submitted)

• AMBER– 46 Resource Entities are AMBER due to missing data

• GREEN– 87 Resource Entities are GREEN




MP-11 scores posted February 1st.

Observations of Resource Entities reporting RED– Personnel changes– Work load (NERC audits, etc.)– Contact information on file with ERCOT out of date– Absent from help sessions– Disengaged in market redesign effort– Planning data difficult to come by

RARF Issues

• Understanding Nodal Parameters

– Completion of ramp rate curves

– Completion of times/energy (min up time, min offline time, start times, weekly energy, etc.)

– Completion of configurations and transitions for combined cycle

• Incomplete forms

– Protection

– Auxiliary load

– Generator details

– Reactive capability

– Transformer details

• More precision necessary for Nodal / LMPs

– Additional modeling of generator-owned transmission elements

– Private modeling of private networks for reliability

• Data not readily available



Efforts to Correct RARF Data

• Known problem areas for the entire market include– Transformer Details– Ramp Rates– Reactive Capability Curves– Resource Parameters

• Efforts moving forward to validate data needed by Nodal systems include– Validation of data by experts of each system using data– Providing feedback to Resource Entities on improving data– Documenting explanations and specific details to assist with

workshop and ultimately new registrations



RARF Addendum 1 Update

• Preliminary submittal information– By unit: 375 received of 537 expected (70%)– Additional assets to be registered in model, such as BKR G1



Resource Registration – Looking Forward *

• February 29: Addendum 2 due (CC only)

• February 7 – 22: Revision of A/S Attestations (by QSE, by Unit)

• February – March: Resource Mapping (MP10)

• March: RARF Workshops based on entity type (Wind, CC, PUN, Load, and all other Generation)

• March 15: End of acceptance of RARFs and addendums; conclude data validation of data received through RARF iterative process

• March 15 – April 7: Hold on RARF submittals to create final RARF to send to Resource Entities

• April 7 – April 25: Resource Entities review and submit certified RARF to ERCOT– From this point on – all submittals must be certified and on the final

RARF form

* Dates may change to meet NMMS or EDS needs
