Status:
Proposed MOD-001-2 was adopted by the NERC Board of Trustees on February 6, 2014 and filed with the applicable regulatory authorities on February 10, 2014.
Background:
The “MOD A” initiative focuses on address outstanding FERC directives from Order 729 as well as identifying other issues based on operational lessons learned.
The standards involved are:
· MOD-001-1a – Available Transmission System Capability
· MOD-004-1 – Capacity Benefit Margin
· MOD-008-1 – Transmission Reliability Margin Calculation Methodology
· MOD-028-1 – Area Interchange Methodology
· MOD-029-1a – Rated System Path Methodology
· MOD-030-2 – Flowgate Methodology
NERC initiated an informal development process to address directives in Order No. 729 to modify certain aspects of the MOD A standards. Participants were industry subject matter experts, NERC staff, and staff from FERC’s Office of Electric Regulation. Questions emerged as to whether certain MOD A requirements were appropriately addressed through NERC Reliability Standards, specifically whether certain MOD A requirements addressed market or competitive issues rather than reliability issues. The group sought to reorient the MOD A standards to focus on the reliability-related aspects of ATC.
The ad hoc group decided to present a pro forma standard that consolidates the MOD A standards into a single standard covering only the reliability-related impact of ATC and AFC calculations, such as the need for Transmission Service Providers (TSPs) to implement their ATC calculations in a consistent manner and share ATC data with neighboring TSPs or other entities who need such data for reliability purposes. The consolidated approach is intended to maintain NERC’s focus on developing and retaining requirements that support the reliable operation of the Bulk-Power System (BPS).
