(headquartered in Nagoya City, Aichi Prefecture; Toyohisa Yamada, President; hereinafter "Yamada Shokai HD"), a developer of dustproof and waterproof portable power supplies that can be used outdoors even in the rain, and Nagoya Kizai Co. (headquartered in Chiyoda-ku, Tokyo; Naoki Yamaguchi, President; hereinafter "Athlitera"), a developer of dustproof and waterproof portable power supplies that can be used outdoors even in the rain, have developed a new type of large-capacity portable power supply for the realization of a decarbonized society.

Together, we will develop and provide solutions to solve problems such as noise, vibration, and accidents caused by exhaust gas at infrastructure sites and to achieve resilience for people and the earth.

Background and future development of new products
　Yamada Shokai HD, Nagoya Kizai, and AsriTerra are committed to reducing their environmental impact as part of their efforts to achieve the SDGs (Sustainable Development Goals). In order to contribute to the realization of a decarbonized society and the building of a sustainable society, we are preparing to develop new services utilizing the new large-capacity portable power supply developed by AsriTerra.

By utilizing the new large-capacity portable power source in place of the gasoline generators that are mainly used at infrastructure sites, it will be possible to eliminate noise, vibration, and exhaust gas emissions. In addition, the newly developed functionality specifically designed for gas and water construction sites is expected to reduce the defect rate of work at infrastructure sites, thereby contributing to cost reduction.

We will continue to promote technological and business development that contributes to solving the challenges of living infrastructure in order to contribute to the realization of a decarbonized society and the building of a sustainable society.
