Daiichi-Kasei Co., Ltd., a leading Japanese manufacturing company, has partnered with EPC provider LINET Co., Ltd. and remote monitoring system developer thingnario Co., Ltd. to accelerate the realization of a sustainable future through ESG initiatives.
Sustainable ESG Management: Daiichi-Kasei’s Environmental Responsibility
In recent years, companies around the world have increasingly recognized the importance of ESG (Environmental, Social, and Governance) initiatives—not only in reducing CO₂ emissions but also in ensuring business continuity and increasing corporate value.
Daiichi-Kasei places strong emphasis on reducing environmental impact and has proactively introduced renewable energy into its operations. In particular, the company has taken steps to ensure stable power supply during disasters as part of its Business Continuity Plan (BCP). To support this effort, Daiichi-Kasei has installed a 767 kW solar PV system and a 100 kW/200 kWh battery storage system at its factory, in collaboration with LINET and thingnario. This initiative not only promotes carbon neutrality but also ensures that the factory cafeteria can serve as an evacuation center with a reliable power supply in emergencies.
Challenges in Maximizing Renewable Energy and Ensuring Disaster Preparedness
While the introduction of solar PV and battery systems improves energy efficiency, several key challenges emerged:
1.Self-Consumption Constraints:Due to regulations prohibiting reverse power flow to the grid, it is essential to optimize battery charge/discharge schedules to avoid wasting excess solar energy.
2. Real-Time Energy Management Needs:Since solar generation fluctuates significantly with weather, it is necessary to monitor real-time generation and consumption data and automatically control battery operations for efficient energy use.
3.Emergency Backup Power Planning:In anticipation of power outages or natural disasters, maintaining sufficient battery reserves is crucial. Manual settings, however, are time-consuming and not ideal for responding to sudden emergencies.
Optimized Energy Management with the PHOTON Remote Monitoring System
To solve these challenges, Daiichi-Kasei adopted PHOTON, a solar remote monitoring system developed by thingnario. Leveraging AIoT (AI + IoT) technology, PHOTON enables real-time monitoring, smart control, and automated energy management, significantly improving the operational efficiency of combined solar and battery systems.
1.Real-Time Energy Data & Automated Battery Optimization:PHOTON monitors load demand, solar output, and battery status in real time. AI algorithms analyze energy needs and automatically determine optimal charge/discharge timing—minimizing wasted energy and maximizing renewable energy usage.
2. One-Click Emergency Mode Activation:When a potential blackout is predicted, PHOTON can automatically switch to disaster-preparedness mode with a single click. It adjusts the energy plan to ensure sufficient battery reserves, enhancing responsiveness compared to manual methods.
3. Stable Power Supply to Evacuation Areas:In the event of a major disaster, PHOTON instantly adjusts battery usage to ensure continuous power supply to designated shelters—supporting Daiichi-Kasei’s ESG commitment to community resilience and coexistence.
From Corporate Value to Environmental Responsibility: Building a Sustainable Future Together
By implementing thingnario’s PHOTON monitoring system, Daiichi-Kasei has significantly improved energy management efficiency and established a robust energy security system. From reducing energy waste to disaster resilience, thingnario’s smart energy technologies are empowering businesses to move toward a more sustainable and future-ready model.
