NOTICE DATE: May 21, 2015 NOTICE TYPE: M-B052115-01 NPRR SHORT DESCRIPTION: Implementation Details for NPRR626, NPRR665, NPRR645, NPRR598 and Other Binding Document (OBD) INTENDED AUDIENCE: ERCOT Market Participants and Settlement Personnel DAYS AFFECTED: June 22-26, 2015 LONG DESCRIPTION: On June 22-26, 2015, ERCOT will implement Nodal Protocol Revision Request (NPRR) 626, Reliability Deployment Price Adder (formerly "ORDC Price Reversal Mitigation Enhancements"), NPRR665, As-Built Clarification of Reliability Deployment Price Adder, NPRR645, Real-Time On-Line Capacity Revisions, NPPR598, Clarify Inputs to PRC and ORDC, and OBD, Methodology for Setting Max Shadow Prices. o Responsive Reserve Manual Deployment Extensible Markup Language (XML) Message XML message sent to Load Resources other than Controllable Load Resources for manual deployment of Responsive Reserve Service will be updated to show a value (MW) equal to the telemetered net power consumption minus the telemetered Low Power Consumption (LPC). Currently, the XML message shows a value (MW) equal to the Responsive Reserve Responsibility. o New Reports: There are no new reports associated with these NPRRs, however the new Reliability Deployment Price Adder is being added to existing reports. Additional columns are also being added to some reports, as follows: Report Name EMIL ID Report Type ID Columns added Column Description SCED Total Available Reserves and Price Adders Based on ORDC NP6-323-CD 13221 RTORDPA Real-Time On-Line Reliability Deployment Price Adder per RTD interval RTRRUC Sum(RUC-committed Units' LDL) per SCED, Real-Time relaxed RUC LDL MW RTD Indicative Total Available Reserves and Price Adders Based on ORDC NP6-325-CD 13222 RTRRMR Sum(Online RMR Units' LDL) per SCED, Real-Time relaxed RMR LDL MW RTDNCLR Sum(Deployed RRS MW from Load Resources) per SCED Historical Real-Time Reserve ORDC Price Adder NP6-792-ER 13231 RTDERS Sum(Deployed ERS) per SCED RTOLLASL Sum(Online Resources' LASL) per RTD interval RTOLHASL Sum(Online Gen Resources' HASL) per SCED Real-Time Reserve Prices Based on ORDC for 15-minute Settlement Interval NP6-324-CD 13220 RTRDP 15-minute Real-Time On-Line Reliability Deployment Price Historical Real-Time Reserve Prices Based on ORDC for 15-minute Settlement Interval NP6-793-ER 13240 o Public Dashboards/Displays: The Reliability Deployment Price Adder will be included in the following public dashboards and displays, similar to the way the Real-Time Online and Offline Price Adders display. · LMP Contour - RTM-LMP and RTM-SPP · Real-Time LMPS for the latest SCED run · Real-Time LMPs for Load Zones and Trading Hubs · Real-Time Settlement Point Prices o New Settlement Charge Types: 1.

Determination of exclusion scenarios called out in 6.7.4 (3) a. If: TWTG q, r, p < (TPVLSL_FACTOR * (AVGTLSL q, r, p * ¼)) AND STATUSSTARTUP q, r, p =1 AND HNSADJ q, r, p > 0 Then, Set: TPVLSLFLAG q, r, p =1 Else, If: TWTG q, r, p >= (TPVLSL_FACTOR * (AVGTLSL q, r, p * ¼)) Then, Set: TPVLSLFLAG q, r, p =1 Otherwise, Set: TPVLSLFLAG q, r, p =0 b. Set CAPEFLAG q, r, p = 1 in every interval for Resources that are a: i) Non-WGR Intermittent Renewable Resource (IRR). - Intermittent Renewable Resource = 'Y' AND Fuel Type Category <> "WIND" ii) Nuclear Resource. - Fuel Type Category = "NUC" iii) Reliability Must-Run (RMR) Unit- Resource contracted per Start and Stop Time (RMR Contract Table). And, set CAPEFLAG q, r, p = 1 in intervals that contain any of the below scenarios: iv) A Resource has a telemetered STARTUP Resource Status and has less than or equal to zero Non-Spin Ancillary Service Responsibility. (STATUSSTARTUP q, r, p = 1 AND HNSADJ q, r, p <= 0) v) A Resource has a telemetered SHUTDOWN Resource Status. (STATUSSHUTDOWN q, r, p = 1) vi) A Resource has a telemetered ONTEST Resource Status. (STATUSONTEST q, r, p = 1) vii) A Resource has a telemetered net real power (TWTG) less than 95% of the telemetered Low Sustained Limit (AVGTLSL). (TPVLSLFLAG q, r, p = 0) viii) The intervals are included in hours that a Resource has been Reliability Unit Commited (RUC) and the Commitment was NOT bought back. (RUC q, r, p,rucid= 1) For any interval where none of the above scenarios are true, set CAPEFLAG q, r, p = 0 3. Application of 6.7.4 (3) exclusion scenarios to amounts calculated pursuant to paragraphs 6.7.4 (2)(a) and(b). a.

If: CAPEFLAG q, r, p = 1 Then, set: RTMGA q, r, p = 0 Else, set: RTMGA q, r, p = RTMG q, r, p d. Review RTOLHSLRA and RTMGA values by q, r, p and cap any RTMGA value for an interval at the RTOLHSLRA value. If: RTMGA q, r, p > RTOLHSLRA q, r, p Then, set: RTMGA q, r, p = RTOLHSLRA q, r, p Else, set: RTMGA q, r, p = RTMG q, r, p 4. Application of 6.5.7.3(4)(e) to the proxy curve creation process in the Settlement System which is necessary for the calculation of Real Time Average Incremental Energy Cost (NPRR665) a. For each RUC-committed Resource that has not submitted an Energy Offer Curve, ERCOT shall create a proxy Energy Offer Curve as described below: MW Price (per MWh) HSL RUC price floor, as detailed in paragraph (1) of Section 6.4.4.1, Energy Offer Curve for RUC-Committed Resources Zero Value of the RUC price floor, as detailed in paragraph (1) of Section 6.4.4.1 b. For each RUC-committed Resource that has submitted an Energy Offer Curve, ERCOT shall create a monotonically increasing proxy Energy Offer Curve as described below: MW Price (per MWh) HSL (if more than highest MW in Energy Offer Curve) SWCAP 1 MW above highest MW in QSE submitted Energy Offer Curve (if less than HSL) SWCAP minus $0.01 Energy Offer Curve Greater of the RUC price floor, as detailed in paragraph (1) of Section 6.4.4.1, or the QSE submitted Energy Offer Curve Zero Greater of the value of the RUC price floor, as detailed in paragraph (1) of Section 6.4.4.1, or the first price point of the QSE submitted Energy Offer Curve o New Settlement Bill Determinants: The following new bill determinants will be implemented for NPRR 626 and NPRR645: Bill Determinant Short Description Extract Extract Table CAPEFLAG Capacity Exclusion Flag RTM CODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL LARDASIRNAMT Load-Allocated Reliability Deployment Ancillary Service Imbalance Revenue Neutrality Amount per QSE RTM CODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL RTMGA Real-Time Adjusted Metered Generation per QSE per Settlement Point per Resource RTM CODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL RTOLHSLRA Real-Time Adjusted On-Line High Sustained Limit for the Resource RTM CODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL RTRDASIAMT Real-Time Reliability Deployment Ancillary Service Imbalance Amount RTM CODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL RTRDASIAMTTOT Real-Time Reliability Deployment Ancillary Service Imbalance Market Total Amount RTM MODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL RTRDP Real-Time On-Line Reliability Deployment Price RTM MODE MTKINPUTHEADER MKINPUTINTERVAL RTRDRUCRSVAMT Real-Time Reliability Deployment RUC Ancillary Service Reserve Amount RTM CODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL RTRDRUCRSVAMTTOT Real-Time Reliability Deployment RUC Ancillary Service Reserve Market Total Amount RTM MODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL UGENA Adjusted Under Generation Volumes RTM CODE RTMOUTPUTHEADER RTMOUTPUTINTERVAL o New Settlement Factor/FactorValue: The following new Factor will be implemented for NPRR665: Factor Short Description Extract Extract Table RUCPFLR RUC Price Floor PRDE FACTOR FACTORVALUE ACTION REQUIRED: Implement changes to shadow Settlement systems in compliance with NPRR626, NPRR665, NPRR645, and NPRR598.
