Remote energy and grid equipment
Replacement parts take years. Sites are far from crews.
Up to this long to get a large power transformer. Lead times almost doubled since 2021.
IEA, 2025
Remote substations, solar sites and microgrids run on equipment that is slow to replace and far from crews. The computers that watch them should outlast the wait.
Mru Field runs on the processors already in the equipment. When one fails and nobody can come, it continues on the ones left and delivers only results it can check. Status: decision core at TRL 3; first field pilot planned for 2027.
01
Computers fail one by one
Radiation, heat and age take out processors and memory. Nothing is replaced until the next visit.
02
No one to ask
When two computers disagree, there is no operator to say which one is right.
03
The link is thin
Bytes per message, or nothing until the next window. Problems have to be solved on site.
Three computers. Then two. Then one, still working.
Most redundant systems stop when they lose their majority. Mru Field steps down instead, and says which mode it is in.

Three computers vote. One bad result is outvoted.
2 alive · compare
Two compare. A known-answer test finds the faulty one.
1 alive · self-check
The last one checks its own work and keeps watching the site, at half speed.

Questions
Does Mru Field need new hardware?
No. It is software for the processors you already deploy. It runs beside your control code and decides which computer to trust as parts fail.
Does it touch protection relays?
No. It runs on monitoring and control computers, not on certified protection.
How do we start?
Use the form below. We first model your hardware and show what each redundancy design returns over its whole life. Then we plan a pilot on your own equipment.
