Presentation Transcript

  1. NPRRs • 642NPRR Constraint Management During Energy Emergency Alerts. This Nodal Protocol Revision Request (NPRR) seeks to improve management of congestion during an Energy Emergency Alert (EEA) by proposing: • Language that provides a mechanism for ERCOT Operations to manage constraints in EEA 2 or 3 to higher Facility ratings when applicable for those constraints identified as limiting generation output; and• Language that reconsiders use of double-circuit contingencies during emergency operations based on ERCOT Transmission Grid conditions. • 645NPRR Real-Time On-Line Capacity Revisions. This Nodal Protocol Revision Request (NPRR) modifies NPRR568, Real-Time Reserve Price Adder Based on Operating Reserve Demand Curve, Phase 1 inputs to the calculation of Real-Time On-Line Capacity by including On-Line Non-Spinning Reserve (Non-Spin) in start-up mode, eliminating under generation intervals, and capping Real-Time Metered Generation (RTMG) at the High Sustained Limit (HSL) to prevent negative On-Line capacity for Wind-powered Generation Resources (WGRs). 

  2. NPRRs • 645NPRR Real-Time On-Line Capacity Revisions (conti). Additionally, resource-level bill determinants for adjusted HSL (Real-Time Adjusted On-Line High Sustained Limit for the Resource (RTOLHSLRA)) and RTMG (Real-Time Adjusted Metered Generation per QSE per Settlement Point per Resource (RTMGA)) will be provided for transparency. • Additionally, new Resource-level bill determinants have been added to the Phase 2 grey box language to better represent the manner of implementation. • 648NPRR Remove References to Flowgate Rights. This Nodal Protocol Revision Request (NPRR) deletes references to Flowgate Rights (FGRs) for consistency with NPRR599, Removal of FGR-Specific Settlement Language, which the ERCOT Board approved on 6/10/2014, and aligns Protocol language with ERCOT systems for Congestion Revenue Rights (CRRs), Settlements and Credit, which do not have the capabilities of valuing or settling FGRs. 

  3. NPRRs • 658NPRR Changes to Annual Reporting Requirements for RUC Payments Made to Resources with PPAs. This Nodal Protocol Revision Request (NPRR) proposes the discontinuation of the posting of the Annual Report requirement if there are no Make-Whole Payments for Resources  with Power Purchase Agreements.  ERCOT Market Information List (EMIL) ID, NP5-661-M. • 659NPRR Discontinue RMR Cost Data Deviation Requests/Responses Report. This Nodal Protocol Revision Request (NPRR) proposes the discontinuation of the posting requirement for Reliability Must Run Cost Data Deviation Requests/Responses, ERCOT Market Information List (EMIL) ID, NP3-558-M.   • 664NPRR Index Fuel Price. This Nodal Protocol Revision Request (NPRR) introduces an Index Fuel Price (IFP).  Resources may designate an IFP based on the Gas Daily’s Waha index price, or the weighted price of the Gas Daily Houston Ship Channel index price and the Gas Daily Waha index price.  The default IFP shall be the Fuel Index Price (FIP). 

  4. NPRRs • 664NPRR Index Fuel Price. This Nodal Protocol Revision Request (NPRR) introduces an Index Fuel Price (IFP) (conti). Resources that designate an IFP based on Waha index price or the weighted price must submit documentation to ERCOT indicating such designation and provide proof of physical delivery from such areas, as described in the Verifiable Cost Manual.  In addition, a Real-Time Make-Whole Payment provision is included to address exceptional fuel cost events that are not resolved by the change to an IFP. • 665NPRR As-Built Clarification of Reliability Deployment Price Adder. This Nodal Protocol Revision Request (NPRR) details how the Energy Offer Curves for Reliability Unit Commitment (RUC)-Committed Resources will be extended or created for Security-Constrained Economic Dispatch (SCED) and the pricing run to determine the Reliability Deployment Price Adder.  This NPRR also clarifies language for related data that will be sent and/or posted during the Operating Hour. 

  5. NPRRs • 666NPRR Clarification for the CRR Balancing Account. This NPRR provides clarification of the process for the monthly CRR Balancing Account in accordance with NPRR580, approved by the ERCOT Board of Directors on 2/11/2014.
