Power grids are becoming more digital, more distributed and more complex. At the same time, many Distribution Network Operators face shrinking operational teams, increasing cyber‑security risks and infrastructure that must run reliably for decades.
How can utilities manage thousands of substations, routers and field devices without increasing operational complexity?
This question is the focus of the latest episode of the “Powering the Future” podcast by Smart Grid Forums, featuring Paul Cullen, co‑founder of Garderos. In the conversation, he shares insights into how utilities can simplify grid communications while strengthening operational resilience and cyber security.
Key topics discussed in the podcast
In the episode, Garderos Co-founder Paul Cullen explains:
- why zero‑touch provisioning is becoming essential for operating large fleets of routers across thousands of substations
- how utilities can deploy and update thousands of devices remotely, reducing the need for on‑site engineering work
- how edge computing on industrial routers enables applications to run directly at the grid edge
- how a virtual RTU can replace additional hardware and significantly reduce cost, cabinet space and power consumption
- why open‑source software is increasingly required in public tenders and how it improves transparency in critical infrastructure projects
The conversation also highlights how utilities can maintain consistent configurations and rapid security updates across large device fleets – an increasingly important capability as cyber threats evolve.
