NERC CIP-003-9 response requirements: Roadmap to compliance and security

Best Practices, CCUG, Controls / By Team-CCJ

The third and final in the NAES, ABS Group, Network Perception cybersecurity webinar series covered NERC CIP-003-9: What Now? Response Requirements. While the NERC standard is still subject to revisions and tweaks in the coming months, there is enough “writing on the wall” for low-impact bulk electric system (LIBES) sites to begin the long slog towards

Low-impact assets and NERC CIP-003-9: Should dos vs must dos

Best Practices, CCUG, Controls / By Team-CCJ

Perhaps the best way to think about how to respond to NERC-CIP-9, which seeks to protect the bulk electric system from a coordinated attack on smaller, low-impact assets which can result in a catastrophic event on the interconnected system, is this: Rather than think in terms of complying with the new standard, think about defending

Fairview: Successes attest to the value of remote M&D

Advanced GTs, Best Practices / By Team-CCJ

Powerplants built over the past several decades are packed with instrumentation, transmitters, and computers. This extensive automation has allowed reduced staffing levels while introducing challenges for effectively analyzing and acting on degrading conditions that may occur long before alarm levels are reached. Many combined cycles use all, or portions of, remote monitoring and diagnostic (M&D)

Fairview: Better DCS screens improve starting reliability

Advanced GTs, Best Practices / By Team-CCJ

Fairview incurred several plant trips following commissioning because of valves hanging up and/or key parameters being overlooked until it was too late for the Mark VIe control system to keep the unit in service. After a handful of failed starts, staff began to discuss how plant operation could be made more reliable and profitable. Most

Fairview: Redundant ammonia injection equipment reduces probability of NOx exceedance

Advanced GTs, Best Practices / By Team-CCJ

Soon after commissioning, staff discovered that a single point of failure of the ammonia-injection control valve could create an emissions exceedance, limiting the plant’s response and output, as dictated by state environmental permitting. An hourly NOx exceedance was experienced less than one month after commissioning because of a faulty flowmeter indication. It limited the amount

Empire’s upgrades zero-in on solutions for fall prevention

7F Users Group, Best Practices / By Team-CCJ

Falls are among the most common causes of serious work-related injuries and deaths. OSHA general industry standards require fall protection for persons working at heights of 4 ft or greater above a lower level (6 ft for construction). In 2021, falls remained the top OSHA citation for the 11th consecutive year. Fall protection systems include
