1. Initial ERCOT Parking Deck Prioritization Recommendation
Troy Anderson
ERCOT – Business Integration

2. Evaluation of Parking Deck Items is Underway
With Nodal go-live behind us, ERCOT has began the impact assessment of Parking Deck items and new NPRRs/SCRs
Work is proceeding as time allows, based on the volume of Nodal Stabilization and Deferred Defect work
Board-approved Priority taken into account
Limited selection of items chosen to reduce resource impacts immediately after go-live
This bundle is referred to as Phase 1
See next slide for list of items
Phase 2 of impact assessment will begin soon
Market input requested on items for this phase

4. Evaluation of Parking Deck Items is Underway
ERCOT has reviewed the results and recommends actions that fall into 3 categories
Recommended for implementation in 2011
Not recommended for implementation in 2011
Recommendation TBD (additional estimation time needed)
Funding Recommendations – General Guidelines
If “Source” = “Parking Deck” then use Parking Deck funds
If “Source” = “Post-Go-Live” then use PPL funds
If case can be made for Stabilization funding then Stabilization

5. Evaluation of Parking Deck Items
2011 Implementation Recommended
NPRR208 – Registration and Settlement of Distributed Generation (DG) Less Than One MW
Target Delivery = September 2011
150 day market notice required between Board approval and implementation
NPRR285 – Generation Resource Base Point Deviation Charge Corrections
Target Delivery = June 2011
IMPORTANT: Impact assessment is subject to change based on potential cross-impacts with the resolution of PRR830
NPRR293 – Requirement to Post CRR Option and Obligation Quantities Cleared in DAM or Taken to Real Time
Target Delivery = May 2011
NPRR302 – Correct Fuel Type Language for Mitigated Offer Cap
Target Delivery = March 2011
Pending Board approval (still in stakeholder process)
Total cost of these items = $54k-$65k
Total labor hours of these items = hours

6. Evaluation of Parking Deck Items
Implementation Not Recommended at This Time
NPRR219 – Resolution of Alignment Items A33,A92,A106,A150 - TSPs Must Submit Outages for Resource Owned Equipment & Clarification of Changes in Status of Transmission Element Postings
Cost to implement greatly exceeds the offsetting labor savings achieved with this project
Need to consider alternate approaches or combining with one or more related efforts
NOGRR050 – Resolution of Reporting Issues Related to NPRR219
Not recommended at this time due to its connection to NPRR219

7. Evaluation of Parking Deck Items
Recommendation TBD
NPRR221 – Automated Default Uplift Invoice
NPRR251 – Sync of PRR845, Definition for IDR Meters and Optional Removal of IDR Meters at a Premise Where an Advanced Meter Can be Provisioned
NPRR290 – ERCOT Publication of DAM PSS/E Files
NPRR303 – Requirement to Post PTP Options Cleared in DAM or Taken to Real-Time
SCR759 – acLineSegment Name Length Increase in Information Model Manager
SCR760 – Recommended Changes Needed for Information Model Manager and Topology Processor for Planning Models
