Project 2017-01 Modifications to BAL-003-1.1

Status
A supplemental 14-day nomination period for additional Standards Authorization Request drafting team members is open through 8 p.m. Eastern, Wednesday, August 9, 2017 
The nomination period is being reopened at the request of the NERC Standards Committee.  There was considerable overlap in the nominations received for this project and Project 2017-06 Modifications to BAL-002-2.  The Standards Committee requested the additional nomination period to 1) reduce the overlap between the two aforementioned projects; and, 2) increase the diversity within the two drafting teams.  The Standards Committee is expected to appoint members to the team September 2017.
Background

The 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. Now that the standard is in place and the data is available for analysis, minor errors in assumptions as well as process inefficiencies have been identified.  It was anticipated that as frequency response improves, the approaches embedded in the standard for annual samples may need to be modified.  In addition to fixing the inconsistencies identified in the Frequency Response Annual Analysis Report (FRAA), the drafting team may separate the administrative and procedural items and reassign them to an alternative process subject to ERO and NERC Operating Committee approval.

Standard(s) Affected:
BAL-003-1 Frequency Response and Frequency Response Setting | BAL-003-1.1 Frequency Response and Frequency Response Setting

Purpose/Industry Needurpose/Industry Need

Revise the BAL-003-1 standard and process documents to address: (1) the inconsistencies in calculation of IFROs due to interconnection Frequency Response performance changes of Point C and/or  Value B; (2) the Eastern Interconnection Resource Contingency Protection Criteria; (3)  the frequency nadir point limitations (currently limited to t0 to t+12), (4) clarification of language in Attachment A, i.e. related to Frequency Response Reserve Sharing Groups (FRSG) and the timeline for Frequency Response and Frequency Bias Setting activities.  (5) The BAL-003-1 FRS Forms need enhancements that include, but may not be limited to, the ability to collect and submit FRSG performance data. Additionally, the supporting procedural and process steps may be removed from Attachment A and captured in an ERO and NERC Operating Committee approved Reference Document such that timely process improvements can be made as future lessons are learned.
