NERC Conference Reinforces Need to Balance Compliance and Operations

by Mark Rabuano – Manager, NERC Services, NAES Corporation

In late August, NAES hosted its fifth NERC Conference in Seattle. Our theme this year, ‘Sustaining Reliability: Balancing Operations and Compliance,’ was particularly salient for NAES, given its role as a leading operator of power plants and itself a registered entity responsible for ensuring NERC compliance. This theme has come increasingly into focus as we see a shift in NERC’s reliability risk priorities and its approach to risk-based compliance monitoring and enforcement. The conference drew over 140 attendees, represented by numerous NAES plants, NAES senior leadership, other registered entities across the country, NERC, FERC and leadership from five Regional Entities.

Our speakers reinforced the conference theme. CEO Bob Fishman kicked off the event with an overview of the NAES organization, its core values and the market trends and drivers currently impacting both the power sector and the grid’s functionality. Jim Robb, NERC President and CEO, placed those remarks into sharper focus in his discussion of NERC’s strategic priorities: the integration of inverter-based technologies, the pace of change in the nation’s resource mix, and cyber and physical security. Among NERC’s future challenges, Mr. Robb cited the need to balance its strategic goals and resource needs with the fiscal realities facing the power industry.

FERC Commissioner Neil Chatterjee offered his own perspective on the industry, noting in his keynote remarks that protecting the reliability of the bulk power system (BPS) ranks among the Commission’s highest priorities, while acknowledging the trend of rapid changes in the nation’s resource mix. In addition, Mark Lauby, NERC Senior Vice President and Chief Reliability Officer, educated the audience on NERC’s reliability risk priorities, which are mapped according to their impact on reliability and likelihood of occurrence. Chief among these are the changing resource mix, BPS planning and cyber security vulnerabilities.

Conference TwoLeaders from many of the Regional Entities underscored in their presentations the respective regions’ compliance monitoring and enforcement program (CMEP) priorities. Midwest Reliability Organization President and CEO Sara Patrick described the attributes of “Highly Effective Reliability Organizations.” Ruchi Shah, WECC Director of Risk Assessment and Mitigation, focused on the value and importance of internal controls. Texas RE Director of Compliance Assessments Curtis Crews offered his views on best practices in communication and effective mitigation. Todd Curl, SERC Senior Manager of Compliance Monitoring, provided his region’s outlook on CMEP areas of focus and the value of industry outreach to reinforce compliance.

Speakers from some of our registered entity peers – including EDF Renewables, Seattle City Light and Sacramento Municipal Utility District – offered case studies on practical compliance and operational challenges they’ve successfully navigated to support their organizations. The conference also featured six breakout sessions where NAES employees and other attendees shared compliance advice and lessons learned on implementation of current and upcoming NERC Standards, including PRC-019-2, CIP-003-6 and CIP-003-7.

Finally, we want to offer appreciation to our attendees, speakers and sponsors for supporting the event and contributing to the lively exchange of ideas. You’ve not only enriched the NAES community but helped to promote continuous improvement in the industry.

    CAISO Generator Modeling Process and Data Requirements

    Don’t wait until the last minute. You should allow time for at least one iteration with CAISO so that you are complete and deemed compliant before your deadline.

    On August 1, 2018, CAISO introduced a revised Business Practice Manual for Transmission Planning Process (BPM), which includes new data requirements for interconnected generation resources within the ISO’s footprint. Section 10 of the BPM establishes revised data requirements and compliance procedures for all participating generators including non-NERC registered entities. While additional requirements have been placed on larger NERC registered facilities, these changes may pose an even greater burden to entities that have been exempt from NERC mandated modeling and protection requirements.

    New data requirements include voltage and frequency protection models, power flow models, and in some cases, sub-synchronous resonance models. These models must be verified using criteria listed in the BPM, which can only be performed by entities with modeling software and knowledge of modeling practices.

    NAES is prepared to assist entities with data aggregation, modeling, and testing to ensure compliance with CAISO’s data requests. The following links will allow entities to determine when to expect their individual data requests (phase) and what data will be required (category).

    Business Practice Manual (BPM)

    Entity Category and Phase Listing

    CAISO Transmission Planning Website

    TPL-007

    TPL-007 establishes planning criteria for induced currents caused by geomagnetic disturbances. The standard is applicable to facilities using transformer(s) with a high side, wye grounded winding operated above 200 kV and can require both submittal of general geomagnetic data (R2) and thermal impact assessments (R6) depending on results of Planning Coordinator analysis.

    VOLTAGE AND REACTIVE (VAR) STANDARDS

    VAR-501-WECC

    VAR-501-WECC requires applicable entities within the WECC region to confirm performance settings and characteristics of Power System Stabilizers (PSS). NAES provides physical testing and reporting services to address WECC’s specific PSS requirements.

    PERSONNEL PERFORMANCE, TRAINING AND QUALIFICATIONS

    PER-006

    PER-006 requires Generator Operators to provide training to personnel who are responsible for the Real-time control of a generator. NAES has developed specific protection system training materials suitable for compliance with the Standard and provides this training both on and off site

    PROTECTION AND CONTROL (PRC) STANDARDS

    PRC-001

    PRC-001 requires entities to coordinate protection system changes with other affected parties. NAES offers both procedural documentation and engineering services to establish the required coordination for both PRC-001 and PRC-027.

    PRC-002

    PRC-002 requires the installation and operation of disturbance monitoring equipment (DME) for applicable entities. NAES can assist with the design and installation of DME as well as ongoing compliance support.

    PRC-019

    PRC-019 requires applicable entities to show coordination between voltage regulating controls, limiters, equipment capabilities, and protection settings. NAES produces PRC-019 specific coordination studies for both traditional generators and renewable projects to establish compliance with the Standard.

    PRC-023

    PRC-023 requires load responsive protective relays be set according to criteria within the Standard to ensure settings do not limit transmission loadability. NAES provides full engineering analyses to maintain compliance with this Standard.

    PRC-024

    PRC-024 requires applicable entities to ensure generator protective relays do not trip within predefined frequency and voltage limits. NAES can complete protection settings analyses and provide compliance documentation that clearly identifies protection settings as they relate to NERC’s “no trip” zones.

    PRC-025

    PRC-025 establishes minimum settings requirements for load-responsive relays protecting generators, step up transformers, and auxiliary transformers. NAES utilizes predefined calculation options as well as simulations to determine a facility’s compliance status and development of new relay settings if required.

    PRC-026

    PRC-026 requires applicable entities to perform load responsive relay settings analyses based on criteria identified within the Standard. Entities are typically notified by the Planning Coordinator when an analysis is required. NAES performs all required studies to establish compliance.

    MODELING, DATA, AND ANALYSIS (MOD) STANDARDS

    MOD-025

    MOD-025 requires Real and Reactive Power capability testing for individual generating units over 20 MVA or facilities with over 75 MVA of generation capacity. NAES offers site specific test procedures and/or complete onsite testing services to meet the requirements of this standard.

    MOD-026

    MOD-026 requires verification of excitation or volt/var control dynamic models through utilization of either system disturbances or physical testing. NAES offers full testing and modeling services to meet the requirements of this standard.

    MOD-027

    MOD-027 requires verification of governor or active power/frequency control dynamic models through utilization of either system disturbances or physical testing. NAES offers full testing and modeling services to meet the requirements of this standard.
