AMEYA360:Murata added four Japanese factories to import self-generating equipment with solar panels and batteries

　　To achieve the RE100, Murata will introduce new battery systems at four plants in Japan, which will use 100 percent renewable energy in the future. The four plants that have introduced new battery systems include Sendai Murata Manufacturing Plant (Sendai, Miyagi Prefecture), Ise Murata Manufacturing plant (Tsumi, Mie Prefecture), HAKUI Murata Manufacturing plant (Yuba, Ishikawa Prefecture), and WAKURA Murata Manufacturing Plant (Shichio, Ishikawa Prefecture).

　　With the goal of achieving a sustainable society, we will continue to promote the renewable energy of the electricity used in the whole business activities of Murata Group and contribute to reducing the environmental load of the regional society. The battery system was first introduced into use in Kanazu Murata Manufacturing Company (Fukui Prefecture Tohara City) in November 2021.

　　After this introduction, there will be 5 plants operating this system in Japan, and the cumulative CO2 emission reduction will reach 1,897 tons.

　　The system integrated management of production plan, electricity consumption, weather information, power generation forecast information in large-scale solar panels and battery units, and combined with Murata's unique energy management system, can optimize the use of energy in real time. In the daytime, the system can monitor the increase and decrease of production and the change of weather, but also can efficiently manage the use of self-generated electricity and battery charging and discharging, and reduce the power supply load of the system stably. In addition, the system will charge the battery at night, in case of daytime power demand, help to stabilize the supply load.

　　In recent years, the rise of sea level and temperature and abnormal weather caused by global warming have become major social issues, and the use of renewable energy has become very important. In particular, it is difficult to predict the supply and demand of electricity in summer and winter in Japan, and the supply network is unstable due to the instability of renewable energy generation. Therefore, companies not only need to promote the use of renewable energy with additionality, but also need to improve the efficiency of energy management. In order to solve such social problems, Murata is making continuous efforts to achieve a sustainable society by optimizing energy use by using battery units as well as solar panels for self-generating electricity.

　　The storage unit used in this system fully demonstrates the advantages of the secondary batteries of Murata Production, which can realize long-term stable operation.

　　According to the different weather conditions and production projects, the operation conditions of each village station vary greatly. In the future, we will analyze and accumulate knowledge and experience on the system operation of each stronghold, and strive to extend this system to more business offices and factories.

　　Murata has identified "Strengthening climate change measures" as an important task and has been promoting the introduction of renewable energy in a bid to contribute to solving global social issues. We strive to achieve the group's total greenhouse gas emission reduction target in business operations, and actively invest in all businesses to promote energy conservation and the use of renewable energy.

　　In the future, the Murata Group will continue its efforts to promote the use of renewable energy in Japan and overseas locations, and continue to promote measures to combat climate change.
