Artist's impression of the completed renewable energy-utilizing data center under development in Okuma Town, Fukushima Prefecture
Eco Kaku Co., Ltd. (Headquarters: Sano City, Tochigi Prefecture; Representative Director: Shigezo Ito; hereinafter "Eco Kaku") is pleased to announce that its "Renewable Energy-Utilizing Data Center Business" in Okuma Town, Fukushima Prefecture, has been selected as a "Good Practice of Renewable Energy Utilization" by the Ministry of the Environment, and has been featured in the "Collection of Good Practices of Renewable Energy Utilization by Data Centers" published today, May 20.
This project involves the construction of container-type data centers equipped with solar power generation systems to self-supply a portion of the massive power demand associated with AI and GPU usage using renewable energy. In the Ministry of the Environment's collection of good practices, Eco Kaku's initiative is introduced as a "Leading Model of Distributed Container Data Centers Based on a Renewable Energy Infrastructure."
■ Why "Renewable Energy x Container Data Center" Now?
Due to the spread of generative AI and the expanding use of high-output GPU servers, the power demand of data centers is growing rapidly. While data centers are critical infrastructure supporting the future digital society, the increase in power consumption and the need for decarbonization have become major social challenges.
Eco Kaku is addressing this by moving away from concentrating large-scale data centers in urban areas, and instead promoting a model that distributes container-type data centers to regions with surplus power grid capacity.
In this project in Okuma Town, Fukushima Prefecture, solar power generation facilities will be installed on the data center site to self-supply a portion of the electricity demand with renewable energy. This aims to resolve environmental challenges by reducing the load on the power grid and lowering CO2 emissions. Furthermore, it aims to create a sustainable regional industrial foundation that generates local employment, revitalizes the local economy, and increases regional tax revenues.
According to the Ministry of the Environment's collection of good practices, this project is expected to reduce CO2 emissions by 1,219 tons annually and self-supply a portion of its electricity consumption through onsite solar power generation.

■ The "Generate, Store, and Use" Energy Model Target by Eco Kaku
Eco Kaku's unique approach goes beyond simply building data centers. Leveraging its expertise in the development, design, construction, and operation of renewable energy sources, particularly solar power, the company designs the flow of energy itself within the local region.
[Generate Power]
Generate clean electricity by utilizing onsite and regional renewable energy resources.
[Store Electricity]
In the future, the company aims to achieve more stable utilization of weather-dependent renewable energy through integration with storage systems such as grid-scale battery storage.
[Use Where Needed]
Utilize the generated power in critical infrastructure such as data centers required for the AI and GPU era, thereby promoting local production and consumption of electricity.
This concept of "Generate, Store, and Use" is a crucial mechanism for not only introducing renewable energy but also utilizing it effectively within the local community.
Eco Kaku has previously been engaged in industrial solar power, solar sharing (agrivoltaics), grid-scale storage batteries, and utilizing unused or abandoned agricultural land to foster symbiosis with agriculture and promote renewable energy.
This data center project builds upon and further develops Eco Kaku's existing initiatives in renewable energy promotion, agrivoltaics, grid-scale storage batteries, and the utilization of abandoned farmland. By combining renewable energy with digital infrastructure, this new social-problem-solving business model not only contributes to the realization of a decarbonized society but also helps generate local employment, revitalize the local economy, and strengthen regional infrastructure.

■ Regional Distribution and Speed Enabled by Container Design
One challenge in establishing large-scale data centers is the time required to secure high-capacity power supplies and complete large-scale construction work.
In contrast, the container-type data centers adopted by Eco Kaku feature a high degree of freedom in site selection and are easy to deploy flexibly in areas with surplus grid capacity. By compacting the necessary equipment, it allows for phased deployment and expansion, enabling agile infrastructure development in response to demand in the rapidly evolving AI and GPU markets.
Furthermore, distributed regional data centers help avoid over-concentration in urban areas, leading to risk dispersion during disasters and improved business continuity. Combining the utilization of renewable energy with regionally distributed locations aims to achieve both decarbonization and resilience.
■ Moving Towards a New Model of Regional Symbiosis with Renewable Energy and Digital Infrastructure from Okuma Town, Fukushima Prefecture
Building a new industrial model that combines renewable energy and digital infrastructure in Okuma Town, Fukushima Prefecture, where this project is implemented, is highly significant from the perspectives of regional symbiosis and regional revitalization.
Eco Kaku will combine its expertise in the development, design, construction, and operation of renewable energy with its setup for equipment installation and operations management required for the data center business to achieve both lower environmental impact and stable digital infrastructure.
Marking the selection for the Ministry of the Environment's "Good Practice of Renewable Energy Utilization" as a major milestone, Eco Kaku will continue to grow alongside local communities as a company dedicated to solving social challenges through the utilization of renewable energy, the introduction of grid-scale storage batteries, agrivoltaics, and the data center business.
