TRC is supporting El Paso Electric to upgrade four existing power stations by developing new settings and other enhancements building off current plant and system parameters.
Our settings reports provide a detailed review of the proposed settings at four gas turbine generating plants including their generating units and generator step-up transformers. The settings study was reviewed, and our team recommended revised settings, if necessary where stated in the study. Relay protective elements left unused in the initial settings report were developed and added. Our relay reports developed also considered compliance with NERC Standards: PRC-006-1, PRC-015-1, PRC-019-1, PRC-024-1, and PRC-025-1.
As a result, the power stations in the El Paso Electric portfolio can ensure that the protection settings loaded in their relays are correct and up to date for the current system and plant conditions. El Paso Electric is also able to ensure that their current protection settings are compliant with existing NERC standards.

NERC Compliance Success Through a Corporate Community Approach
May 6, 2024
While utilities often work in technical silos, NERC auditors are trained to cross check compliance evidence and data between interrelated standards. Working in silos often leads to inadvertent situations where the compliance evidence from one standard is used but inconsistent with information produced or used by other standards. To assure compliance evidence reporting objectives are achieved in each applicable standard and requirement, it is important to identify interrelationships and create a framework where subject matter experts (SMEs) in all technical disciplines consider the evidence data consistency requirements. NERC compliance auditors are also trained to examine process flows and identify whether they are comprehensive or incomplete. Auditors determine the appropriateness of information by examining the quality and completeness of compliance evidence. They examine the relevance, validity, consistency and reliability of evidence used for addressing the audit reliability objectives and supporting their findings and conclusions. If conflicting evidence is found, they will identify this in their formal Regional Entity (RE) audit report findings which could further lead to a compliance violation and related fines. To improve the likelihood of favorable NERC audit compliance outcomes and avoid the need for implementing mitigation plans, individual contributors and SMEs should look at certain cross linked compliance evidence to assure consistency between approaches used to record compliance evidence. Doing so will allow a company to spend more time on executing core reliability duties and enhance company regulatory obligations. Avoid waiting until the RE compliance audits are underway to identify conflicting evidence situations.

The changes address the need to winterize facilities; ensure the accurate reporting of design specifications to reliability coordinators for generating units; and the need for balancing authorities and reliability coordinators to be aware of, and plan for, generating units’ limitations during extreme cold weather.
NERC Seeks to Improve GADS Reliability Performance Reporting
August 26, 2021
Under the enabling legislation that created the Electric Reliability Organization, NERC is responsible for assessing the reliable performance of the power system. One way NERC does so is via an industry reporting system for generation and transmission. The Generator Availability Data System (GADS) has been used by NERC and the industry for over 40 years to obtain data on the generation component of the power system[1]. Due to the rapidly changing generating resource mix, it is essential that NERC have comprehensive plant, event, outage and performance data for photovoltaic and wind generation to ensure reliability. As renewable technologies are increasingly deployed, a complete set of generation asset performance statistics is necessary to allow NERC to evaluate the system’s ability to serve load, the performance of the power system and to forecast any potential reliability issues due to resource inadequacy. Therefore, NERC is proposing to make the following enhancements to the GADS data collection process for renewable generation: Add Generator Owners that operate solar photovoltaic facilities of 20 MW or greater to the Generating Availability Data System (referred to as “GADS-PV”); and Expand GADS Wind (“GADS-W”) reporting to include connected energy storage and event reporting.

NERC Addresses Single Points of Failure in Protection Systems Among Other FERC Concerns
October 25, 2018
Under the proposed NERC TPL-001-5 standard, utilities with transmission planning responsibilities will be required to identify reliability risks related to protection system failures and take mandatory corrective action. It will be critical to have an in depth understanding of your company’s protection system settings and to perform the system studies necessary to identify where single points of failure may result in cascading tripping of transmission elements. Mitigation actions may require the installation of redundant protection systems which in turn may lead to significant substation redesign. Transmission planners and planning coordinators should begin preparing for any necessary protection system changes. TPL-001-5 Overview NERC began studying the reliability risk associated with single points of protection system failure starting in 2011 as directed in FERC Order 754. TPL-001-5 will bring significant changes for Planning Coordinators and Transmission Planners as they perform annual Planning Assessments. There is a new obligation to adequately account for the reliability risk posed by single point of protection system failure via risk-based Assessment. This reliability risk management approach will be implemented through modifications to the Category P5 Planning Event which is described in Table 1 of the TPL-001-5 standard. NERC believes that the most cost-effective Corrective Action Plans to address unacceptable system performance for the P5 Planning Events will likely be to add protection system component redundancy in certain cases. Protection system redundancy changes to address Category P5 Event system performance violations should reduce or even negate non-redundant component related risks that need to be considered in assessing transmission system performance. These risks will be identified during simulations of certain extreme events as required under the standard. TPL-001-5 also addresses reliability risks related to outage management as directed in FERC Order 786. The standard requires utility planners to consider maintenance outages of significant facilities as well as outages for critical long lead time to repair or replace equipment. Specifically, it addresses stability analysis to assess system performance for conditions expected during possible unavailability of long lead time equipment. Although it is not a NERC defined term, it is believed that a “spare equipment strategy will be sufficient to allow flexibility for utilities to conduct both steady state and stability analysis required by TPL-001-5. For example, a utility’s spare equipment strategy may include the warehousing of a replacement transformer to be installed given the failure of an in service transformer. When a utility’s spare equipment strategy may prevent major transmission equipment from being out-of-service for one year or more, this possible equipment unavailability need not be assessed as part of TPL-001-5.
NERC Proposes Compliance Monitoring and Enforcement Plan for 2019
