In 1989, the Québec grid collapsed as equipment protection relays tripped in a cascading sequence of events. Six million consumers were left without power for up to nine hours. The cause of this major outage was a geomagnetic disturbance (GMD).
Geomagnetic disturbances occur during solar storms caused by charged particles, that are ejected by the sun toward Earth. These high-energy particles, known as a coronal mass ejection, can travel to Earth in 14 to...
How utilities can protect operations from penetration BY MICHAEL STUBER, Itron For utilities deploying Smart Grid solutions, the major security concern is often the field devices. Utilities and vendors have long understood that field devices such as meters, switches, routers, and concentrators...
A small town in North Carolina has filed a lawsuit against Duke Energy, one of the largest utility companies in the United States, alleging that the company has been deceptive in its efforts to downplay the environmental impact of its operations. The lawsuit, filed by the town of Smithfield, claims...
Taking a stand against threats to ensure reliability BY JOHN FINNIGAN, Environmental Defense Fund If Ben Franklin lived today, he might say that nothing is certain but death, taxes, and cyberattacks. The U.S. electric grid is under constant cyberattack, according to a survey of electric utilities...
The importance of up-to-date critical system monitoring BY MARLEE ROSEN, Rosen Associates Supervisory control and data acquisition (SCADA) networks contain computers and applications that perform critical capabilities in delivering essential services and commodities (for example, electricity,...
Utilities are rethinking cybersecurity. The zero-trust model replaces perimeter defense with continuous verification—of every device, vendor, and data path—across the substation and supply chain. The End of Perimeter Thinking For decades, substation cybersecurity meant building walls:...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
The Federal Energy Regulatory Commission (FERC) is seeking public input on proposed "ride-through" reliability standards for inverter-based resources (IBRs), including wind, solar, and battery systems. These standards aim to ensure that IBRs can maintain operation during grid disturbances, such as...
The rapid shift toward renewable energy resources (RERs) has placed significant demands on traditional power systems. To address these challenges, modern energy infrastructure is evolving into smart grids, leveraging advanced technologies like Virtual Power Plants (VPPs) to enhance grid...
A small town in North Carolina has filed a lawsuit against Duke Energy, one of the largest utility companies in the United States, alleging that the company has been deceptive in its efforts to downplay the environmental impact of its operations. The lawsuit, filed by the town of Smithfield, claims...
In a significant move that underscores the growing demand for reliable and sustainable energy to power the expanding digital infrastructure, the Federal Energy Regulatory Commission (FERC) has approved an interconnection agreement between Talen Energy, Amazon Web Services (AWS), and Exelon. This...
