The formal comment period and ballots for draft
two of Reliability Standard BAL-003-3 – Frequency Response and Frequency Bias Setting concluded 8 p.m. Eastern, Thursday, June 1, 2023. The comments received and ballot results can be accessed via the links below.
The standard drafting team will review all comments received and determine the next steps of the project.
Background
Reliability Standard BAL-003-1 became effective in 2015. Supporting documents for BAL-003-1 were developed using engineering judgment on the data collection and process needed to determine the Interconnection Frequency Response Obligation (IFRO), as well as the processing of raw data to determine compliance. In the course of implementing the standard, minor errors in assumptions and process inefficiencies have been identified. Further, it was anticipated that as Frequency Response (FR) improves, the approaches embedded in the standard for collecting annual samples would need to be modified.
This project is a two-phase approach. The first phase addressed the Phase 1 recommendations in the Standard Authorization Request (SAR), resulting in Reliability Standard BAL-003-2. On July 15, 2020, the Federal Energy Regulatory Commission approved Reliability Standard BAL-003-2 and work began on the second phase of Reliability Standard improvements.
The scope of the work identified in the second phase is to (1) establish a real-time reliability standard addressing the necessary FR 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.
Standard(s) Affected: BAL-003-2 Frequency Response and Frequency Bias Setting
Purpose/Industry Need
Proposed Reliability Standard BAL-003-3 and its process documents address the Project 2017-01 Phase II recommendations in the underlying SAR. In particular, the proposed revisions would make the Interconnection IFRO calculations and associated allocations improve representation of current conditions and considers characteristics affecting FR (e.g., load response, mix and type of generation). The proposed revisions would also modify provisions of the standard pertaining to the Frequency Response Measure (FRM) in order to ensure that over-performance by one entity does not negatively impact the performance evaluation of another entity. In addition, the proposed modifications seek to include all of the appropriate applicable entities in light of the revised requirements and make IFRO and FRM allocations as equitable as possible.Further, the Reliability Standard revisions reflect the expectation that obligations associated with FRM reporting will eventually transition from occurring under the Reliability Standard to occur under a request issued pursuant to NERC Rules of Procedure (ROP)[1], Section 1600 – Request for Data or Information, subject to NERC Board of Trustees approval. This is similar to transition for misoperations data collection effected under PRC-004-3[2]. Data submission would continue under the present process until any Section 1600 data request could be issued pursuant to the rules under the NERC ROP.
