Applications/Examples of results

● Realizing disaster preparedness with storage batteries By combining industrial storage batteries with solar power generation, it becomes possible to respond with self-generated power and storage batteries until recovery in the event of a prolonged power outage. This provides "peace of mind and safety" in case of an unexpected power outage, and also contributes to external "credibility and trust." ● Simultaneously enhancing the main power source of renewable energy and resilience As global warming accelerates, there is a growing demand for energy conservation in offices and facilities. By combining solar power generation with storage batteries, we can effectively utilize renewable energy sources. This contributes to CO2 reduction and significantly decreases energy consumption through energy creation. ● From "selling" electricity to "using" it The selling price of solar power is declining, and there are increasing cases where it is more advantageous to use the generated electricity wisely to reduce electricity costs (self-consumption) rather than selling it. By introducing storage batteries, it becomes possible to consume the generated electricity in-house. During normal times, it is possible to flatten the load of electricity consumption through peak cutting and peak shifting, leading to reductions in electricity costs and environmental impact.

  ●Important BCP Measures for Companies BCP (Business Continuity Plan) is required to prevent activities from coming to a standstill during a disaster. Securing power during emergencies is extremely important. It leads to "peace of mind and safety" in case of an unexpected power outage, as well as external "credibility and trust." In recent years, there have been increasing instances of natural disasters where basic functions cannot be maintained. This not only results in economic losses but also negatively impacts the brand image of companies. The introduction of energy storage systems can ensure power supply during outages and contribute to the rapid recovery of business operations.

  The electricity generated is shifting from "selling" to "using." There is a growing demand for environmentally friendly initiatives, such as promoting the adoption of renewable energy. Additionally, the selling price of solar power has been declining, leading to an increasing number of cases where it is more advantageous to use the generated electricity efficiently to reduce electricity costs (self-consumption) rather than selling it. By introducing storage batteries, it becomes possible to consume the generated electricity for one's own use, enabling "self-consumption." During normal times, it is possible to achieve load leveling of electricity consumption through peak cut/peak shift, which can help reduce electricity costs and mitigate environmental impact.

  ●Utilization of Clean Energy Reduction of CO2 emissions through integration with solar power generation. Enhancing corporate value while considering the environment. The introduction of storage batteries is very effective as an energy-saving measure for companies. By combining with solar power generation, it significantly reduces energy consumption through energy creation. It becomes possible to consume the "generated electricity" from renewable energy for self-consumption.

  ●Promotion of SDGs Contributing to the achievement of the SDGs (Sustainable Development Goals) and enhancing corporate value through initiatives. As companies are strongly urged to reduce CO2 emissions, the introduction of storage batteries contributes to efforts to improve environmental issues and support local communities. Active engagement in CSR (Corporate Social Responsibility) activities and environmentally conscious corporate practices lead to an enhancement of "corporate strengths and values."

  ●Energy Saving through Peak Cutting By cutting the maximum power usage with a storage system, you can reduce high-voltage contract fees. The industrial storage system 'BLP', which allows for peak cut power settings for environmental measures and energy-saving purposes in factories, warehouses, and large commercial facilities, controls the "maximum demand" by forced discharging during peak usage times, contributing to the reduction of electricity costs.

• 

  ●Peak Shift Effect Industrial storage batteries significantly enhance energy-saving effects when integrated with renewable energy devices such as solar power generation. Charging the storage battery during low-cost time periods (mainly at night) allows for savings. By using electricity from the charged storage battery during high-cost time periods, you can save on electricity bills. By setting a schedule for charging and discharging according to time periods, the peak shift effect can also be achieved.

  ●Ensuring Power Supply is the First Step in BCP Measures In times of emergency, companies are required to be prepared to continue essential operations. To swiftly implement a Business Continuity Plan (BCP) during a disaster, it is necessary to secure at least the minimum infrastructure. Among these, ensuring emergency power supply capable of handling long-term power outages is emphasized. In the case of large-scale disasters like the Great East Japan Earthquake, it is anticipated that power outages could last more than a week, and immediately after a disaster, there is a possibility of isolation due to road disruptions and shortages of supplies caused by distribution issues. Using small batteries or gasoline-powered generators as emergency power sources would require stocking a large number of batteries and fuel, which can be difficult if procuring fuel becomes challenging. However, if self-consumption solar power generation and industrial storage batteries can be introduced, it would be possible to use the generated electricity and storage batteries in combination, enabling long-term measures against power outages even during large-scale blackouts.

  The introduction of storage batteries allows for the optimal operation of renewable energy facilities, enabling efforts for decarbonization during normal times. Achieving a decarbonized society requires renewable energy. However, due to the instability of power generation output influenced by weather, it is necessary to store renewable electricity for stable supply. In this context, large-capacity storage batteries are indispensable. The government's decarbonization policy has clearly indicated a stance to support the utilization of renewable energy combined with storage batteries, and as the movement towards achieving carbon neutrality by 2050 accelerates, the introduction of storage batteries contributes to decarbonization efforts.
