MEINS (Villares de la Reina, Salamanca, Spain) took part in The Smarter E Europe 2026 (Munich), the world’s largest renewable energy, storage and electrical infrastructure trade fair (100,000+ professionals, ~2,000 companies). The company presented the CSET-145, the first fully operational, full-scale compact high voltage substation shown at the event, rated up to 138kV.
What is the CSET-145 | Compact Substation
A prefabricated substation solution developed by MEINS to accelerate the deployment of electrical infrastructure for renewable energy, BESS and data center projects.
| Parameter | Value |
|---|---|
| Maximum operating voltage | 138kV |
| Footprint reduction vs. conventional substation | >10x |
| Commissioning time | ~2 weeks |
| Format | Modular, prefabricated, transportable |
| Status at the fair | Fully operational unit, not a mockup or digital simulation |
Technical differentiator: unlike conventional civil-works substations, the CSET-145 is manufactured and tested in-plant, shipped fully assembled, and installed on-site in weeks rather than months, drastically reducing civil works footprint.

Frequently asked questions
What is a compact substation and how does it differ from a conventional one?
A compact substation such as the CSET-145 is manufactured in-plant as a prefabricated module and installed on-site in weeks, compared to the months required by a traditional civil-works substation, while also reducing the required footprint by more than 10 times.
What voltage does the CSET-145 operate at?
Up to 138kV.
Where can the CSET-145 be seen in operation?
It was exhibited fully operational at The Smarter E Europe 2026 (Munich). Summary video: https://www.youtube.com/watch?v=VUP5Vif98XQ
