View Rule

The Commission proposed to amend its regulations to incorporate by reference, with certain enumerated exceptions, the latest version (Version 003.3) of the Standards for Business Practices and Communication Protocols for Public Utilities adopted by the Wholesale Electric Quadrant (WEQ) of the North American Energy Standards Board (NAESB).  WEQ Version 003.3 included standards developed in accordance with recommendations of the Department of Energy sponsored cybersecurity surety assessment of the NAESB Business Practice Standards that was conducted in 2019.  Additional standards were developed in response to the directives from FERC Order No. 890, such as the standards developed to support Parallel Flow Visualization, intended to improve congestion management procedures for the Eastern Interconnection.  The WEQ Version 003.3 Standards also included, in their entirety, the WEQ-023 Modeling Business Practice Standards contained in the WEQ Version 003.1 Standards, which addressed the technical issues affecting Available Transfer Capability (ATC) and Available Flowgate Capability (AFC) calculation for wholesale electric transmission services, with the addition of certain revisions and corrections.  The revisions made by NAESB in the WEQ Version 003.3 Standards are designed to aid public utilities with the consistent and uniform implementation of requirements promulgated by the Commission as part of the pro forma Open Access Transmission Tariff (Docket Nos. RM05-5-29 and RM05-5-30).
