A digital substation is a modernized electrical substation that replaces traditional analog equipment and copper wiring with digital signaling, intelligent electronic devices (IEDs), and fiber-optic communication. It enables real-time data exchange, advanced automation, and greater efficiency in managing grid operations and infrastructure health.
For decades, the idea of the digital substation hovered just beyond reach—a theoretical construct wrapped in futuristic language and layered with uncertainty. It was described as an “intelligent substation,” capable of processing...
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...
As the substation RTU takes on more applications, such as Human-Machine-Interface (HMI), alarm annunciation, math & logic and “relay communication processing”, its need for high availability increases. Anything that takes the RTU out of service – configuration change, firmware update, or...
How to improve situational awareness of grid operations BY MARK FEDERLE, QinetiQ North America The adoption of Smart Grid technology in recent years has accelerated the modernization of the electric utility grid. This is a positive development given that the grid infrastructure in North America is,...
Exploring communications for real-time network visibility BY DONALD POLLOCK, Ambient Corporation In August 2013, a report entitled “Economic Benefits of Increasing Electric Grid Resilience to Weather Outages” prepared by the White House Council of Economic Advisors and the U.S. Department of...
A Smart substation digitizes protection and control, enabling utilities to detect faults faster, manage DER volatility, and reduce outage risk. The payoff depends on architecture, cybersecurity, and edge analytics, not just new relays. The shift toward smart substations is inseparable from broader...

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...
The evolving demands of modern power grids necessitate the adoption of advanced technologies that can provide enhanced efficiency, reliability, and flexibility. Smart transformers are at the forefront of this technological revolution, offering a range of capabilities that significantly improve the...
NEURAL GRID TAKES SMART GRID INTO THE CLOUD The Neural Grid represents more than Smart Grid v2.0—much more. Today, the smart grid implies the legacy mechanical power transmission and distribution (T&D) networks enhanced by pockets of automation, connectivity, and centralized IT systems. The...
When dozens of utilities received stimulus funds for distribution automation projects in 2009, solar was barely a gigawatt-scale market in the U.S. Sandy was simply a lead character in Grease, not a superstorm that would prompt cities and states to reassess the future-readiness of their...
