NATF and NERC Sign Updated MOU at Joint Human Performance Conference
North American Transmission Forum (NATF) President and CEO Tom Galloway and North American Electric Reliability Corporation (NERC) President and CEO Jim Robb marked the start of this week’s human performance conference and workshops by signing an updated memorandum of understanding (MOU) between the two organizations. The MOU is designed to facilitate collaboration and leverage respective and collective strengths to identify existing and emerging risks, prioritize actions, and implement mitigation strategies to advance the reliability, resilience, and security of the Bulk Power System.
“The NATF and NERC recognize the importance of efficient and effective coordination and collaboration in this time of unprecedented industry change,” said Galloway. “This MOU will support our shared goals of identifying and addressing risks and advancing reliability, resilience, and security objectives.”
The conference—a collaborative effort among the NATF, NERC, and the Department of Energy—embodies the goals of the MOU by bringing together industry experts in a cooperative forum to share best practices to help improve human performance on the Bulk Power System.

NATF Posts Document to Assist Industry with PRC-026-1 Tools
The NATF has posted the “Relay Performance During Stable Power Swings (PRC-026-1) Evaluation Tools Reference Document” to our public website for industry use.
NERC Reliability Standard PRC-026-1, “Relay Performance During Stable Power Swings,” requires utilities to evaluate the performance of various load-responsive protective relays in response to stable power swings during non-fault conditions. Impedance-based relays are evaluated against a power swing region defined by the standard. This evaluation is unlike any analysis currently performed when setting most impedance-based relays. Thus, new power swing analysis functions are needed within commercial protection system analysis tools, or utilities must develop custom calculators using general-purpose spreadsheets or engineering calculation software.
This document lists functional attributes for either type of tool. Tool developers may reference this list when developing software requirements specifications.

TPL-001-4 Reference Document Posted for Industry
The NATF has posted version 3.0 of the “NATF TPL-001-4 Reference Document” to our public website for the benefit of the industry.
The document provides guidance regarding the use of consistent, industry-wide approaches to certain topics in NERC standard TPL-001-4. The goal of sharing this information externally is to support responsible Transmission Planners and Planning Coordinators with the various transmission system planning analyses as called for under TPL-001-4, thus enhancing the reliable planning and operation of the entire Bulk Electric System.

NATF CEO Testifies on Blackstart at Senate Committee Hearing
NATF President and CEO Tom Galloway served on a panel of experts and provided testimony during the October 11 Senate Energy and Natural Resources Committee hearing on blackstart, which involves the process of energizing system components following a widespread blackout without support from the grid, and other system restoration plans.
In his written testimony, Galloway noted the significant industry efforts to preserve high levels of grid reliability and resiliency and improve restoration from broad-scope outages, including educating the industry and regulators on resiliency threats, hardening the bulk power system, ensuring adequacy of key spares, augmenting mutual aid, enhancing restoration planning, conducting comprehensive drills and exercises, and increasing coordination with cross-sector (e.g. gas and water) and governmental entities.

EMS External Modeling Reference Document Posted for Industry
The NATF has posted version 2.0 of the “NATF EMS External Modeling Reference Document” to our public website for the benefit of the industry.
The document provides guidance to those working to improve performance of their energy management system (EMS) external models. The intended audience for the document is persons with responsibility for development and maintenance of EMS models for real-time state estimator and real-time contingency analysis.August 03, 2018
NATF CEO Participates in FERC Technical Conference
NATF President and CEO Tom Galloway served as a panelist during the July 31 FERC technical conference regarding the Bulk-Power System. Galloway appreciated the opportunity to provide perspectives on resiliency during panel II (“Advancing Reliability and Resilience of the Grid”), which focused on power system planning and operations challenges and opportunities resulting from the changing generating resource mix.

Cyber Security Supply Chain White Paper and Guidance Posted
The “NATF Supply Chain Risk Management Guidance” and “NATF CIP-013-1 Implementation Guidance” documents have been posted to the NATF public website for industry use.
The “NATF Supply Chain Risk Management Guidance” white paper describes practices for establishing and implementing a supply chain cyber security risk management plan. “NATF CIP-013-1 Implementation Guidance” is an associated document that the NATF has submitted to NERC for consideration as Implementation Guidance as an approach to comply with CIP-013.
These documents are geared to benefit members and the industry and respond to the NERC board resolution of August 2017 where it asked for industry assistance via the drafting of white papers.June 29, 2018
Distributed Energy Resources Document Posted for Industry
The NATF has posted “NATF Reference Document: Distributed Energy Resource Modeling and Study Practices” to the NATF public website.
The increasing penetration of distributed energy resources (DER) is producing new challenges for transmission planners. The reference document provides details to supplement existing documents authored by NERC and others that will help power system planners or study engineers prepare (1) DER models for interconnection-wide power flow cases and dynamic simulations and (2) DER impact assessments on the bulk power system.
Sharing this document with the broader industry will help improve power system modeling and studies being conducted to integrate DER into the Bulk Electric System.
