Are you considering an excitation system upgrade or planning an AVR (Automatic Voltage Regulator) upgrade for your facility? Like aging relays and meters, older excitation systems eventually become obsolete and need replacement. Upgrading lets you take advantage of modern microprocessor-based features. These include event recording, flexible logic, and advanced monitoring and control across multiple communication protocols. In addition, newer excitation systems rely on readily available components. This improves reliability and allows faster part replacement when failures occur.
If your facility operates a generating unit over 20 MVA, a synchronous condenser over 20 MVA, or a generating facility rated at 75 MVA or greater (gross), you need to consider NERC PRC-019 compliance during any excitation or AVR upgrade. NERC PRC-019 coordinates voltage regulating controls, limit functions, equipment capabilities, and Protection System settings. After completing an upgrade or new installation, you must update your NERC PRC-019 report with the relevant commissioning documentation.
For applicable facilities, you must review NERC PRC-019 reports every five calendar years, based on your audit cycle. These reviews confirm proper coordination of excitation limiters and protections. Because audit requirements vary by system topology and technology, technical expertise is critical. A Professional Engineer can guide you through the process. They ensure you complete thorough studies, maintain current reports, and keep your system optimized. They can also program equipment, perform testing, and recommend improvements for your existing setup.
Reesha Tech brings the specialized expertise needed to help your facility achieve full compliance—and maintain it. We offer auditing, compliance support, and staff training. Our in-house team meets the full range of NERC standards. While many companies focus on a single area, Reesha Tech manages the entire compliance process from start to finish. We’re your long-term partner in grid reliability and regulatory success.
