FANUC’s factory in Japan has been running with the lights off since 2001.
Robots build robots there, and the line can run unattended for up to 30 days.
It’s called a dark factory. And it’s no longer science fiction.
So why do so many plants still need dozens of people on every shift?
Usually it’s not about the people. It’s about what’s missing around them: the software, the electronics and the autonomous systems that should be doing the repetitive work. Without them, headcount fills the gap.
When the right systems are in place:
⚡ Energy use drops. Areas without people need far less lighting, heating and cooling. FANUC even switches off the air conditioning.
🎯 Errors drop. Fatigue, distraction, a wrong setting. Human-caused defects and wrong production runs are prevented.
📊 Plans actually hold. Every machine, every stop, every part is recorded. Reporting is instant and schedule adherence becomes measurable.
👥 Teams get leaner and stronger. Fewer people on the floor, and the ones who stay run the system instead of babysitting machines.
Nobody becomes a dark factory overnight. But the first step is clear: knowing what your machines are doing right now, in real time.
At Solcivita, that’s exactly where we start.
