A lights-out factory, often referred to as a dark factory, runs with little to no human presence, enabling it to operate autonomously without onsite human intervention - essentially functioning in the dark. As industries look towards the "factory of the future," autonomous manufacturing in these settings is anticipated to expand across various sectors.

Dark factories also known as "lights-out factories," are revolutionizing the manufacturing industry with cutting-edge automation technologies. These facilities operate without human intervention, leveraging AI-driven Robotics, IoT networks, and intelligent automation protocols to ensure seamless 24/7 operation with minimal energy consumption.

India is moving towards dark factories, but challenges remain. The country's manufacturing sector is expected to embrace partial dark factory operations within the next 7-10 years with fully autonomous, AI-powered factories likely emerging in 15-20 years. Key sectors that will drive this transformation include: Semiconductor, AI-driven, Automation, IoT, Robotics.​
