1. QMWG Update to WMS S. Looney October 9, 2013

2. WMS Assignments NPRR564, Thirty-Minute Emergency Response Service – Discuss concerns expressed at last WMS meeting. – Q: Why is ERCOT getting more 30 minute response at the same time they are talking about purchasing less NSRS? A: This is a true Emergency service which is only deployed in EEA. – Concern: The market needs more information about these loads. Response: ERCOT is looking at automating the data and bringing it into the market registration system. – Concern: These products should have a reliability-based method for calculating procurement quantities. Response: DSWG is looking to revise the month groupings for the products to more accurately specify the load horizons for the contract periods. – Concern: Price reversal due to deployment. Response: Could be addressed through the ORDC which is being considered by the PUCT. – Q: How would ERCOT get 10 minute product if they are cleared with the 30 minute? A: When offered at the same price, ERCOT will preferentially award the 10 minute product.

3. General Update Annual Review of AS Methodology – 2 key Revisions for 2014: (1) Updated wind study for regulation requirement and (2) Removal of load bias for load forecast. – ERCOT requested QMWG members to submit comments. – Removing the load forecast bias improves ERCOT Operations practices for choosing and reporting load forecast. – ERCOT would not be opposed to a bias term added to NSRS requirement.

4. General Update NPRR416, Creation of the RUC Resource Buyback Provision – Implementation delay due to question about Buyback Resources carrying AS. – Consensus of the group, it was the intention of NPRR416 that you could carry AS. – Should implement NPRR416 as is without the ability to carry AS. – Submit a new NPRR with the provision to carry AS so that ERCOT could have the Project group evaluate the impact.

5. General Update NPRR486, Calculation of Generation to be Dispatched and SCR773, Addition of Regulation Feedback to GTBD Calculation – ERCOT has made significant progress and the quantities of regulation deployed have decreased. – Continuing to work through PDCWG open meetings. – Developed metrics including limit on consecutive SCED intervals in which regulation is deployed in only one direction. – ERCOT is working on a PID (Proportional Integral Derivative) type control minimizing s scheduled control error term.

6. General Update SASM Offers – ERCOT continues to see a lack of offers available for SASM. – Are there Protocol revisions needed? – Notification of a SASM to allow offers to be submitted? Wind Forecast Accuracy Report Update – Reports are posted. – Working with another wind service to do a trial of wind forecasting – By the end of the year should have data to compare to current forecasting method WGR Concerns with Commissioning Checklist – Difficulties in getting Commissioning Plan approved. WGR members of QMWG will work with ERCOT to bring back a markup.

7. General Update GREDP Report – Conventional Resources, September 311/312 scored above 90% – CPS 1 consistently greater than 160 this summer – CPS2 99% for August-September – WGRs, 2250 intervals scored, 1950 intervals passed – Congestion intervals significantly reduced due to CREZ – No inter-zonal interface limit issues in West in Q2 or Q3 2013 NDCRC Upgrade for Reactive Test submittal – Improvement in test submittal and approval process since the ERCOT workshop. Continuing work on NDCRC input screens. – Support for NOGRR125, Minimum Notice for Coordinated Reactive Testing
