Macnica and Challenergy launch business partnership to accelerate the spread of small wind turbines that can be installed in urban areas in preparation for disasters

Macnica (headquarters: Yokohama, Kanagawa Prefecture; Representative Director and President: Kazumasa Hara; hereinafter Macnica) and Challenergy, Inc. (Board Director: Sumida-ku, Tokyo; CEO: Atsushi Shimizu; hereinafter "Challenergy") announced today that they have entered into an exclusive sales agency agreement and will begin offering highly robust, compact wind turbines that can be used as emergency power sources in the event of a disaster. Through this business partnership, Macnica and Challenergy aim to create a safer, more secure, and sustainable society by implementing and popularizing new wind turbines that can be used in any environment.

■Background
In recent years, the frequent occurrence of natural disasters has become a serious social issue around the world. When natural disasters such as floods, typhoons, earthquakes, and wildfires occur, power transmission lines and power plants are damaged, resulting in an increasing number of cases where the power supply is cut off. This has a major impact on daily life and economic activity, and securing power is particularly important for important facilities such as medical institutions and evacuation shelters, where securing power is a lifeline.

■The "New Savonius Type" overcomes the challenges of previous wind power generation and can be installed safely even in urban areas
The small wind turbines we are now offering are next-generation wind turbines with a bladeless structure that are resistant to strong winds and quiet. This means they can be installed in residential areas where installation was previously hesitant. We hope that installing these compact wind turbines in companies, hospitals, communities, etc. will help strengthen resilience in the event of power outages or information outages in emergencies.

■Social implementation capabilities created by tag-teaming with Macnica, which works on renewable energy and decarbonization solutions
Macnica has been engaged in the development of perovskite solar cells and lead-acid batteries and the sale of energy-saving solutions as part of its Circular Economy business. Aiming for a more sustainable society, we chose wind power generation as the next candidate for renewable energy. In this context, we have decided to collaborate with Chalenergy, a startup with innovative technological capabilities. In addition to striving to implement Chalenergy's wind turbines more widely in society, we will jointly develop additional IoT technologies to further enhance our services, including the implementation of remote management functions.
