Communications Networks for Electric Utilities

As electric utilities evolve toward smarter, more automated operations, communication networks have become the backbone of reliable power delivery. These networks link field devices, substations, and control centers, supporting SCADA, protection, and metering systems essential to daily operations. Yet as technology advances, understanding how these systems communicate is increasingly important for ensuring reliability, security, and efficient troubleshooting across the grid.

The Communications Networks for Electric Utilities course provides a practical introduction to the communication technologies that power today’s utility operations. Participants will explore how information moves through the network, how different media and protocols support system functions, and how to apply networking concepts in real-world electric utility environments. Through demonstrations, interactive discussions, and hands-on exercises, the course connects foundational theory to field applications. Key course discussion topics include:

• Communication architectures and devices used in substations and distribution networks
• Fiber optics, copper, radio, and cellular communication methods
• Common utility protocols: DNP3, Modbus, and IEC 61850
• Network configuration, monitoring, and troubleshooting practices
• Emerging technologies such as private LTE, 5G, and Time-Sensitive Networking (TSN)

What makes this course unique is its focus on utility-specific, real-world learning, bridging electric utility operational technology (OT) and networking concepts in a clear, applied format. Participants will leave with the knowledge and confidence to support the reliable communication systems that underpin modern power operations.

By the end of this course, participants will be able to:

1. Define the purpose and role of communications in modern utility systems.
2. Identify common communication media (fiber optics, copper, wireless, cellular) and their applications.
3. Explain key network components such as switches, routers, radios, and fiber equipment.
4. Recognize common utility communication protocols (DNP3, Modbus, IEC 61850).
5. Apply basic troubleshooting techniques to identify and resolve communication issues.
6. Discuss cybersecurity considerations in OT communication networks.
