M-A010722-01 Implementation Details of NPRR917, NPRR1052, NPRR1054, and NPRR1065
NOTICE DATE: January 7, 2022
NOTICE TYPE: M-A010722-01 Settlements
SHORT DESCRIPTION: Implementation Details of NPRR917, NPRR1052, NPRR1054, and NPRR1065
INTENDED AUDIENCE: All Market Participants
DAYS AFFECTED: February 1-3, 2022
LONG DESCRIPTION: ERCOT will be implementing system changes between February 1 to 3, 2022, for Protocol language associated with Nodal Protocol Revision Request (NPRR) 917, Nodal Pricing for Settlement Only Distribution Generators (SODGs) and Settlement Only Transmission Generators (SOTGs); NPRR 1052, Load Zone Pricing for Settlement Only Storage Prior to NPRR995 Implementation; NPRR 1065, Implementation Adjustment for NPRR917; and partial implementation of NPRR1054, Removal of Oklaunion Exemption Language.
NPRR917, NPRR1052, and NPRR1065 introduces the following changes to the Nodal Protocols:
- Section 6.6.3.2, Real-Time Energy Imbalance Payment or Charge at a Load Zone – Replaces the Real-Time Metered Generation from Non-Modeled Generators (RTMGNM) billing determinant with Real-Time Metered Generation from Settlement Only Generators Zonal (RTMGSOGZ) billing determinant.
- Section 6.6.3.9, Real-Time Payment or Charge for Energy from a Settlement Only Distribution Generator (SODG) or a Settlement Only Transmission Generator (SOTG) – Establishes new Settlement equations that implement nodal pricing for SODGs and SOTGs.
- Section 6.6.10, Real-Time Revenue Neutrality Allocation – Addition of Real-Time Energy Amount Total for Energy from all SODGs and SOTGs (RTESOGAMTTOT) billing determinant to maintain Revenue Neutrality.
- Section 9.19.1, Default Uplift Invoices – Adds a new parameter to the Default Uplift calculation to include the MWh activity for Settlement Only Generators (USOGTOT).
- Section 9.19.3, Default Uplift Supporting Data Reporting - Adds a new column, Uplift Real-Time Energy Produced by SOG Site (USOGTOT), under the Default Uplift Supporting Data Report.
Partial implementation of NPRR1054 introduces the following changes to the Nodal Protocols:
- Section 6.6.10, Real-Time Revenue Neutrality Allocation –Removal of Real-Time DC Export Amount Total (RTDCEXPAMTTOT) billing determinant from the calculation.

ACTION REQUIRED: Impacted Market Participants should implement changes to their shadow Settlement systems to incorporate the Protocol revisions made by NPRR917, NPRR1052, NPRR1054, and NPRR1065.
ADDITIONAL INFORMATION: Pursuant to Nodal 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.
NPRR917, NPRR1052, NPRR1054, and NPRR1065 and their associated documents can be found on the ERCOT website.
