Improving energy efficiency in the factory by the use of photovoltaic power generation and storage batteries and the "visualization" of power consumption.

The Omika Works produces products for social infrastructure systems, such as electricity, traffic, steel making, water supply/sewerage, and industries. It has introduced the factory energy management system (FEMS) in each building. By controlling power consumption in the building, the system facilitates efficient use of energy. The factory has also installed a photovoltaic power generation system (rated output: 940 kW), storage batteries (capacity: 4,200 kWh), and about 900 power consumption sensors (smart meters) in the factory. In addition to management by building, power consumption by use (air conditioning, lighting, OA, equipment, etc.) is "visualized". Careful energy management has also been implemented for peak power reduction, for example, by forecasting photovoltaic power production and power demand and by planning storage battery charging/discharging. The factory has obtained the ISO 50001*1 certificate, and all employees have been committed to improving energy efficiency. The Omika Works is a smart environmentally conscious factory that strives to improve energy savings by utilizing advanced technologies.
