NOTICE DATE: May 6, 2011 NOTICE TYPE: M-B050611-01 NPRR SHORT DESCRIPTION: Implementation details of NPRR329 INTENDED AUDIENCE: ERCOT Market Participants DAY AFFECTED: May 18, 2011 LONG DESCRIPTION: On May 18, 2011, ERCOT will implement Nodal Protocol Revision Request (NPRR) 329, Security Classification Changes for Extracts/Reports, which was approved by the ERCOT Board on April 19, 2011. NPRR329 changes the security classification of many extracts/reports from "Secure" to "Public". This will allow the data contained within these extracts/reports to be accessible without the use of an ERCOT Digital Certificate. NPRR329 will make the following extracts/reports available publicly: 1. Seven-Day Load Forecast by Forecast Zone 2. Seven-Day Load Forecast by Weather Zone 3. Short Term System Adequacy Report 4. Load Forecast Distribution Factors 5. Settlement Points List and Electrical Buses Mapping 6. DAM Ancillary Service Plan 7. Weather Assumptions 8. Aggregated Wind Generation Resource Power Potential Forecast 9. Actual and Forecasted Regional Wind Production 10. Hourly RMR Services Deployed 11. Daily RUC Active & Binding Transmission Constraints 12. Hourly RUC Active & Binding Transmission Constraints 13. Adverse Weather 14. System-Wide Demand 15. Changes to Transmission Facility Status 16. SCED Shadow Prices and Binding Transmission Constraints 17. Planned Service Four Coincident Peak Calculations Report. The following reports/protocols will be changed from Secure to Public: EMIL ID PRODUCT NAME PROTOCOL DATA SET TYPE NP3-560-CD Seven-Day Load Forecast by Forecast Zone NP3.12(a) ERCOT Forecasted Load NP3-560-CD Seven-Day Load Forecast by Forecast Zone NP3.2.2(3) ERCOT Forecasted Load NP3-560-CD Seven-Day Load Forecast by Forecast Zone NP3.2.3(3)(c) ERCOT Forecasted Load NP3-560-CD Seven-Day Load Forecast by Forecast Zone NP4.2.3(d) ERCOT Forecasted Load NP3-560-CD Seven-Day Load Forecast by Forecast Zone NP6.3.2(3)(b) ERCOT Forecasted Load NP3-561-CD Seven-Day Load Forecast by Weather Zone NP3.12(a) ERCOT Forecasted Load NP3-561-CD Seven-Day Load Forecast by Weather Zone NP3.2.2(3) ERCOT Forecasted Load NP3-561-CD Seven-Day Load Forecast by Weather Zone NP3.2.3(3)(c) ERCOT Forecasted Load NP3-561-CD Seven-Day Load Forecast by Weather Zone NP4.2.3(d) ERCOT Forecasted Load NP3-561-CD Seven-Day Load Forecast by Weather Zone NP6.3.2(3)(b) ERCOT Forecasted Load NP3-763-CD Short Term System Adequacy Report NP3.2.3(3)(a) Shared Protocol Dependency NP3-763-CD Short Term System Adequacy Report NP3.2.3(3)(b) Shared Protocol Dependency NP3-763-CD Short Term System Adequacy Report NP3.2.3(3)(c) Shared Protocol Dependency NP3-763-CD Short Term System Adequacy Report NP3.2.3(3)(d) Shared Protocol Dependency NP3-763-CD Short Term System Adequacy Report NP3.2.3(3)(e) Shared Protocol Dependency NP3-763-CD Short Term System Adequacy Report NP4.2.3(k) Shared Protocol Dependency NP4-159-CD Load Forecast Distribution Factors NP6.3.2(3)(e) Shared Protocol Dependency NP4-159-CD Load Forecast Distribution Factors NP4.2.3(e) Shared Protocol Dependency NP4-160-SG Settlement Points List and Electrical Buses Mapping NP4.2.3(i) Settlement Points NP4-160-SG Settlement Points List and Electrical Buses Mapping NP4.2.3(j) Settlement Points NP4-33-CD DAM Ancillary Service Plan NP3.2.3(3)(d) Shared Protocol Dependency NP4-722-CD Weather Assumptions NP4.2.3(b) Hourly Forecasted Temperatures by Weather Zone NP4-730-SG Aggregated Wind Generation Resource Power Potential Forecast NP4.2.2(5) Short Term Wind Power Forecast Aggregated Wind Generation Resource Power Potential Forecast NP4-732-CD Actual and Forecasted Regional Wind Production NP4.2.2(6) Aggregated Wind Generation Output by Load Zone NP5-108-CD Hourly RMR Services Deployed NP6.3.2(3)(c) Shared Protocol Dependency NP5-754-CD Daily RUC Active & Binding Transmission Constraints NP5.3(3)(b)(i) Active Binding Constraints NP5-755-CD Hourly RUC Active & Binding Transmission Constraints NP5.3(3)(b)(i) Active Binding Constraints NP6-18-AN Adverse Weather NP6.3.2(3)(a)(ii) Shared Protocol Dependency NP6-235-CD System-Wide Demand NP6.3.2(3)(d) Shared Protocol Dependency NP6-661-AN Changes to Transmission Facility Status NP6.3.2(3)(a)(i) Shared Protocol Dependency NP6-86-CD SCED Shadow Prices and Binding Transmission Constraints NP6.3.2(2) Active Binding Constraints NP6-86-CD SCED Shadow Prices and Binding Transmission Constraints NP6.3.2(3)(e) Active Binding Constraints NP6-86-CD SCED Shadow Prices and Binding Transmission Constraints NP6.5.7.1.13(4)(d) Active Binding Constraints NP9-83-M Planned Service Four Coincident Peak Calculations Report NP9.17.1(1) 4 Coincident Peak Calculations ADDITIONAL INFORMATION: Pursuant to Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation. NPRR329 and associated documents can be found on the ERCOT website, under Market Rules, at http://www.ercot.com/mktrules/issues/nprr/326-350/329/index. In conjunction with the change to the data classification of these Extracts/Reports, ERCOT will implement changes to the posting locations of these items on the Market Information System (MIS) to relocate the items from their secure portlet locations into public portlets. New ERCOT.com links will also be created to account for the public posting of these documents. CONTACT: If you have any questions, please contact your ERCOT Account Manager.
