The latest issue of Switchgear Magazine is here!
Dear readers,
We are happy to announce that the new issue of Switchgear Magazine is now available!
This issue addresses the mismatch between deployment on the order of a year for data centres with GWs of demand, and lead-times on the order of a decade for grid expansion. Until baseload generation is installed, we are in the Interregnum and the articles and interviews in these pages are, in some sense, a dispatch from inside it.
Hyperscale data centres have been deployed akin to other large industrial loads – only to later find that the power simply wasn’t there. Some data centres have ended up in mothballs, others were brought online by guerrilla engineering, even if not at full load.
When the grid was not able to supply the power, data centre planners have turned installating their own generators. Local generation capacity, BESS and STATCOMs created what could be called the “Sovereign Gigawatt” – capable of not only keeping the lights on, but also capable of actively supporting the grid.
Inside the New Issue:
- Clean-air GIS at 420 kV: rigorous field validation of F-gas-free extra-high-voltage switchgear, showing what it takes to close the dielectric performance gap with SF₆.
- How digitalization is reshaping the grid right now: from self-predicting switchgear and pre-construction digital twins to self-healing distribution networks and the emerging “power engineer plus coder” hybrid skillset.
- Why the proprietary “black box” is now a strategic liability — and how open-source tools like GIZA and AMI 2.0 are providing the agility utilities need to manage the grid edge securely.
- AI-accelerated discovery of SF₆ alternatives: machine learning and semi-empirical quantum chemistry are screening molecular libraries at scale, cutting decades from the conventional lab timeline.
Our cover interview with Meidensha’s Mr. Shinichiro Kon goes deep on the engineering and commercial reality of scaling dry-air vacuum circuit breaker technology from 145 kV toward EHV, and why technical feasibility is only the beginning of the challenge.
Between the covers, this edition explores:
- CIGRE President Dr. Konstantin Papailiou on the global engineering talent shortage, the long-promised DC breaker, and why “there is no transition without transmission”
- TransnetBW specialist Dr. Laurentiu-Viorel Badicu on how F-gas blends and natural-origin gases compete for the long-term GIS roadmap
- The Current Zero Club on the plasma physics of the final microseconds — the deep science that determines whether the network holds or fails
These insights raise key questions:
- When data centres evolve from grid loads into grid assets, how does substation design change?
- Can AI-driven materials discovery and clean-air insulation technology scale quickly enough to meet both the F-gas regulatory timeline and the demand surge?
- What does it mean for the industry when the fastest path to guarantee reliable power is no longer through the utility, but around it?
To understand the forces now re-engineering the grid from autonomous gigawatt-scale microgrids and SF₆-free switchgear to open-source protection systems and predictive asset management, this issue is essential reading.
