Electricity Today T&D Magazine – Substations and the Grid Spring 2025 Special Edition

In this issue, we explore the essential technologies and communication systems that are shaping the modern electrical grid. As substations evolve from isolated, hardwired facilities into digital, connected, and data-driven hubs, utilities are adopting advanced tools that support high-speed communication, real-time monitoring, and smarter system operation.

The shift toward digital and intelligent substations is redefining how the grid is monitored, protected, and controlled. With protocols such as IEC 61850 enabling standardized data exchange, SCADA platforms providing real-time visibility, and modern cybersecurity practices protecting critical assets, today’s substations operate at the intersection of electrical engineering and advanced networking. These capabilities allow utilities to improve reliability, support renewable energy integration, and build stronger operational resilience across transmission and distribution systems.

This special edition of Electricity Today T&D highlights the core topics essential to understanding the future of substation and grid modernization. Through expert explanations and system-level insights, we take a close look at communication standards, digital automation, cybersecurity frameworks, and grid connectivity technologies that are transforming how utilities design and operate the power network.

Whether you are a substation engineer, protection specialist, SCADA professional, or utility leader, this edition provides clear and practical knowledge to navigate the next generation of substation automation and grid communication.
