basic information

Collaboration between industrial storage batteries and self-consumption solar power generation to reduce CO2 emissions Contributing to decarbonization efforts The industrial storage system <BLP> is ideal for companies' decarbonization efforts through self-consumption solar power generation. By effectively utilizing renewable energy, it leads to CO2 emission reductions, lower electricity costs, reduced environmental impact, and benefits such as CSR (Corporate Social Responsibility), adding value to energy conservation and BCP measures (ensuring power supply during emergencies). 【Features】 ■ Rated output: 30kW / Storage capacity: approximately 73.7kWh ■ Contributes to BCP measures for facilities and companies, as well as reducing environmental impact through self-consumption ■ Compact outdoor installation type that does not require housing storage 【Benefits】 (1) Saves on electricity costs (2) Cost reduction through self-consumption (3) Measures against power outages during disasters ◆ Partnership with NEC Networks & System Integration Comprehensive design proposals for storage batteries and renewable energy equipment are possible. Leveraging extensive implementation experience, we provide consistent support from installation to maintenance operations.

Applications/Examples of results

●Simultaneously improve the main power source of renewable energy and enhance 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 natural 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 has been declining, and it is becoming more advantageous to use the generated electricity efficiently to reduce electricity costs (self-consumption type) rather than selling it. By introducing storage batteries, it becomes possible to consume the generated electricity in-house, enabling "self-consumption." During normal times, we can achieve load leveling of power consumption through peak cutting and peak shifting, leading to reduced electricity costs and measures to lower environmental impact. ●Achieving disaster preparedness with storage batteries By linking industrial storage batteries with solar power generation, it becomes possible to respond with self-generation and storage batteries until power restoration, even in the event of prolonged outages. This provides "safety and security" in case of unexpected power outages and contributes to external "credibility and trust."

  ● Important BCP Measures for Companies BCP (Business Continuity Plan) is required to prevent activities from coming to a standstill during a disaster. Securing power supply during emergencies is extremely important. It leads to "peace of mind and safety" in case of unexpected power outages, 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 facilitate the swift recovery of business operations.

  The electricity generated is shifting from "selling" to "using." There is a growing demand for environmentally conscious initiatives, such as the promotion of renewable energy adoption. Additionally, the selling price of solar power has been declining, leading to an increasing number of cases where it is more beneficial to use the generated electricity efficiently to reduce electricity costs (self-consumption type) 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 power consumption through peak cutting and peak shifting, which can lead to reductions in electricity costs and environmental impact mitigation measures.

  ●Utilization of Clean Energy Reduction of CO2 emissions through connection with solar power generation. Enhancing corporate value while considering the environment. The introduction of storage batteries is highly 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. As companies are strongly urged to reduce CO2 emissions, the introduction of storage batteries leads to active engagement in CSR (Corporate Social Responsibility) activities such as "efforts to improve environmental issues" and "contributions to local communities." Corporate activities that consider the environment will enhance "the strengths and value of the company."

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

• 

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

  ●Ensuring Power Supply is the First Step in BCP Measures In times of emergency, companies are required to prepare 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 a power supply that can handle long-term outages is emphasized. In the case of large-scale disasters like the Great East Japan Earthquake, it is anticipated that power outages could last over a week, and immediately after a disaster, there may be isolation due to road disruptions and shortages of supplies caused by distribution issues. Using small batteries or gasoline-powered generators as emergency power sources requires storing 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 implemented, it becomes possible to use generated electricity and storage batteries together during large-scale power outages, enabling long-term outage measures.

  The introduction of storage batteries enables the optimal operation of renewable energy facilities, making it possible to pursue decarbonization efforts during normal times. Achieving a decarbonized society requires renewable energy. However, due to the instability of power generation output influenced by weather conditions, it is necessary to store renewable electricity to ensure a stable supply. In this context, large-capacity storage batteries are indispensable. The government's decarbonization policy has clearly indicated a commitment to supporting the utilization of renewable energy combined with storage batteries, and as efforts to achieve carbon neutrality by 2050 accelerate, the introduction of storage batteries contributes to decarbonization initiatives.
