The Informal comment period for Phase II of Project 2017-01 Modifications to BAL-003 White Paper concluded at 8 p.m. Eastern, Tuesday,
April 27, 2021.
Background
Two Standard Authorization Requests (SARs) were received for modifying BAL-003-1.1. The first SAR was submitted by the NERC Resource Subcommittee (NERC RS) and the second SAR was submitted by the Northwest Power Pool Frequency Response Sharing Group (NWPP FRSG). The two SARs were merged into a single SAR that proposed a two-phase approach to modifying BAL-003.
Phase I of the SAR has been completed and BAL-003-2 is a currently-enforced standard. Phase II of Project 2017-01 will address the second phase recommendations of the SAR to develop a proposed BAL-003-3 standard.
Standard(s) Affected: BAL-003-2 Frequency Response and Frequency Bias Setting Purpose/Industry Need
This project has been a two-phase approach. The first phase addressed the Phase 1 recommendations in the SAR. The scope of the work identified in the second phase is to (1) establish a real-time reliability standard addressing the necessary frequency response to maintain reliability; (2) establish comparability for the correct responsible entity; (3) develop real-time measurements incorporating topology difference, and (4) eliminate the incorrect indicators.
This second phase of the project addresses the Phase II recommendations in the SAR: Make the Interconnection Frequency Response Obligation (IFRO) calculations and associated allocations: 1) more reflective of current conditions; 2) consider all characteristics affecting Frequency Response (e.g., load response, mix and type of generation); 3) include all applicable entities; and 4) be as equitable as possible; and
Frequency Response Measure (FRM): 1) ensure that over-performance by one entity does not negatively impact the evaluation of performance by another; 2) measure types/periods of response in addition to secondary Frequency Response, particularly primary Frequency Response; 3) include all applicable entities; and 4) make allocations as equitable as possible.
