Resource Controlling Entity Attestation

• In support of Competitive Constraint Test– Determine the total Managed Capacity by each Entity and its Affiliates

on the import and export side. – Managed Capacity for an Entity is a Resource or portion of a Resource

for which the Entity or its Affiliates has the decision-making authority over how the Resource or portion of the Resource is offered or scheduled, either by virtue of ownership, agreement or otherwise.

• Only affects Generation Resources that are transmission connected and have a resource node

• 83% submitted– 463 of 555 units accounted for– ~10% need corrections

• Compilation of submittals to be available as of May 15, 2008

8 Resource Registration

NPRR117

• Resource Registration Clarification– NPRR117 is intended to clarify obligations of a Resource Entity

to register Resource data with ERCOT and the obligations of a Qualified Scheduling Entity (QSE) to submit Resource Parameters for operational purposes to ERCOT.

– NPRR 117 also changes QSE’s obligation to submit Private Use Network design and engineering data to the obligation of Resource Entity.

• Asset registration can be improved/maintained going forward– Require RARF validation by Resources periodically to keep

network model up to date as well as digital certificates active– Develop MP interface to ease data entry and validation by

eliminating spreadsheets and providing MPs direct access to data and status
