Status
Nominations are being sought for additional drafting team members through 8 p.m. Eastern, Friday, September 13, 2024. 
The Standards Committee is expected to appoint members to the drafting team in October 2024. Nominees will be notified shortly after they have been appointed.

Background
The PPMVTF developed this SAR to revise MOD-025-2 to address issues regarding verification and data reporting of generator active and reactive power capability. As stated in the SAR, implementation of the standard has rarely produced data that is suitable for planning models (i.e., the stated purpose of the standard). The current MOD-025-2 verification testing activities require significant time, expertise, and coordination; however, they do not result in data that should be used by planners for modeling purposes. The SAR aims to retain testing activities are useful and focus on more effective means of collecting useful data for planning models. The Reliability, Security, and Technology Committee (RSTC) endorsed the SAR on October 19, 2020.

PRC-019-2 addresses the reliability issue of miscoordination between generator capability, control systems, and protection functions. However, PRC-019-2 was developed with a bias toward synchronous generation and does not sufficiently outline the requirements for all generation resource types. The proposed Standard Authorization Request (SAR) aims to address a number of issues identified by the SPCS and revise the standard to be inclusive of all types of generation resources. The SAR was endorsed by the NERC Planning Committee (PC) on March 4, 2020.

The MOD-025-2 and PRC-019-2 SARs were accepted and authorized for informal posting at the January 20, 2021 SC meeting.

The appointed SAR DT will also determine how to addresses the applicable scope of Project 2020-02 Transmission-connected Dynamic Reactive Resources, which also seeks to modify MOD-025-2 and PRC-019-2. See Project 2020-02 Transmission-connected Dynamic Reactive Resources for additional background.
